                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this Annual Report on Form 10-K ("10-K"), or incorporated
by reference into this 10-K, are forward-looking statements within the meaning
of Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934 that are made based upon, among other things, our current
assumptions, expectations and beliefs concerning future developments and their
potential effect on us. These forward-looking statements involve risks,
uncertainties and other factors, many of which are outside our control, that may
cause our actual results, performance or achievements to be materially different
from any future results, performance or achievements expressed or implied by
these forward-looking statements. In some cases you can identify forward-looking
statements where statements are preceded by, followed by or include the words
"believes," "expects," "anticipates," "plans," "future," "potential," "probably"
or the negative of such terms or similar expressions. Forward-looking statements
in this 10-K, or incorporated by reference into this 10-K, include, but are not
limited to, statements regarding:

         o   projected capital expenditures and related funding requirements;

         o   developments, trends and consolidation in the water and wastewater
             utility industries;

         o   dividend payment projections;

         o   opportunities for future acquisitions, the success of pending
             acquisitions and the impact of future acquisitions;

         o   the capacity of our water supplies, water facilities and wastewater
             facilities;

         o   the impact of geographic diversity on our exposure to unusual
             weather;

         o   our capability to pursue timely rate increase requests;

         o   our authority to carry on our business without unduly burdensome
             restrictions;

         o   our ability to obtain fair market value for condemned assets;

         o   the impact of fines and penalties;

         o   the development of new services and technologies by us or our
             competitors;

         o   the availability of qualified personnel;

         o   the condition of our assets;

         o   the impact of legal proceedings;

         o   general economic conditions;

         o   acquisition-related costs and synergies; and

         o   the forward-looking statements contained under the heading
             "Forward-Looking Statements" in the section entitled "Management's
             Discussion and Analysis" from the portion of our 2005 Annual Report
             to Shareholders incorporated by reference herein and made a part
             hereof.

Because forward-looking statements involve risks and uncertainties, there are
important factors that could cause actual results to differ materially from
those expressed or implied by these forward-looking statements, including but
not limited to:

         o   changes in general economic, business and financial market
             conditions;

         o   changes in government regulations and policies, including
             environmental and public utility regulations and policies;

                                       2

         o   changes in environmental conditions, including those that result in
             water use restrictions;

         o   abnormal weather conditions;

         o   changes in, or unanticipated, capital requirements;

         o   changes in our credit rating;

         o   our ability to integrate businesses, technologies or services which
             we may acquire;

         o   our ability to manage the expansion of our business;

         o   the extent to which we are able to develop and market new and
             improved services;

         o   the effect of the loss of major customers;

         o   our ability to retain the services of key personnel and to hire
             qualified personnel as we expand;

         o   labor disputes;

         o   increasing difficulties in obtaining insurance and increased cost
             of insurance;

         o   cost overruns relating to improvements or the expansion of our
             operations;

         o   increases in the costs of goods and services;

         o   civil disturbance or terroristic threats or acts; and

         o   changes in accounting policies.

Given these uncertainties, you should not place undue reliance on these
forward-looking statements. You should read this 10-K and the documents that we
incorporate by reference into this 10-K completely and with the understanding
that our actual future results may be materially different from what we expect.
These forward-looking statements represent our estimates and assumptions only as
of the date of this 10-K. Except for our ongoing obligations to disclose
material information under the federal securities laws, we are not obligated to
update these forward-looking statements, even though our situation may change in
the future. For further information or other factors which could affect our
financial results and such forward-looking statements, see "Risk Factors." We
qualify all of our forward-looking statements by these cautionary statements.

Pennsylvania. Our other subsidiaries provide similar services in 12 other
states. In addition, we provide water and wastewater service through operating
and maintenance contracts with municipal authorities and other parties close to
our operating companies' service territories. We are the largest U.S.-based
publicly-traded water utility based on number of people served.

Our customer base is diversified among residential, commercial, fire protection,
industrial, other water, wastewater customers and operating contracts and other
customers. Residential customers make up the largest component of our customer
base, with these customers representing 67% of our total water revenues.
Substantially all of our water customers are metered, which allows us to measure
and bill for our customers' water consumption. Water consumption per customer is
affected by local weather conditions during the year, especially during the late
spring and early summer in our northern U.S. service territories. In general,
during these seasons, an extended period of dry weather increases consumption,
while above average rainfall decreases water consumption. Also, an increase in
the average temperature generally causes an increase in water consumption. On
occasion, abnormally dry weather in our service areas can result in governmental
authorities declaring drought warnings and water use restrictions in the
affected areas, which could reduce water consumption. See "Water Supplies, Water
Facilities and Wastewater Facilities" for a discussion of water use restrictions
that may impact water consumption during abnormally dry weather. The geographic
diversity of our customer base reduces our exposure to extreme or unusual
weather conditions in any one area of our service territory.

Our growth in revenues over the past three years is a result of increases in our
customer base and in water rates. The majority of the increase in customer base
is due to customers added through acquisitions. During the three-year period of
2000 through 2002, our customer base increased at an annual compound rate of
3.3%. The customer growth rate in 2003 was 23.8%, and reflects the additional
customers obtained in the AquaSource acquisition on July 31, 2003. In 2004, the
customer growth rate was 11.5% and reflects the additional customers added
through the Heater and Florida Water Services acquisitions. In 2005, the
customer growth rate was 3.5%. Overall, for the five-year period of 2001 through
2005, our customer base increased at an annual compound rate of 8.9%.

Acquisitions and Water Sale Agreements

With approximately 50,000 community water systems in the U.S. (84% of which
serve less than 3,300 customers), the water industry is the most fragmented of
the major utility industries (telephone, natural gas, electric, water and
wastewater). The nation's water systems range in size from large
municipally-owned systems, such as the New York City water system that serves
approximately 9 million people, to small systems, where a few customers share a
common well. In the states where we operate, we believe there are over 22,000
public water systems of widely-varying size, with the majority of the population
being served by government-owned water systems.

                                       5

Although not as fragmented as the water industry, the wastewater industry in the
U.S. also presents opportunities for consolidation. According to the U.S
Environmental Protection Agency's ("EPA") most recent survey of publicly-owned
wastewater treatment facilities in 2000, there are approximately 16,000 such
facilities in the nation serving approximately 72% of the U.S. population. The
remaining population represents individual homeowners with their own treatment
facilities; for example, community on-lot disposal systems and septic tank
systems. The vast majority of wastewater facilities are government-owned rather
than privately-owned. The EPA survey also indicated that there are approximately
6,600 wastewater facilities in operation or planned in the 13 states where we
operate. In 2005, we acquired a business providing on-site septic tank pumping
and other services. This business presently serves approximately 2,000 customers
in southeastern Pennsylvania and northern Delaware.

Because of the fragmented nature of the water and wastewater utility industries,
we believe that there are many potential water and wastewater system acquisition
candidates throughout the United States. We believe the factors driving
consolidation of these systems are:

o  the benefits of economies of scale;
o  increasingly stringent environmental regulations;
o  the need for capital investment; and
o  the need for technological and managerial expertise.

We are actively exploring opportunities to expand our utility operations through
acquisitions or other growth ventures. During the five-year period ended
December 31, 2005, we completed 123 acquisitions or other growth ventures.

We believe that acquisitions will continue to be an important source of growth
for us. We intend to continue to pursue acquisitions of municipally-owned and
investor-owned water and wastewater systems of all sizes that provide services
in areas adjacent to our existing service territories or in new service areas.
We engage in continuing activities with respect to potential acquisitions,
including calling on prospective sellers, performing analyses and investigations
of acquisition candidates, making preliminary acquisition proposals and
negotiating the terms of potential acquisitions.

Water Supplies, Water Facilities and Wastewater Facilities

Our water utility operations obtain their water supplies from surface water
sources such as reservoirs, lakes, ponds, rivers and streams, in addition to
obtaining water from wells and purchasing water from other water suppliers. Less
than 10% of our water sales are purchased from other suppliers. It is our policy
to obtain and maintain the permits necessary to obtain the water we distribute.
Our supplies by principal service area are as follows:

o  Pennsylvania - The principal supply of water is surface water from rural
   streams, rivers and reservoirs. Wells and interconnections with adjacent
   municipal authorities supplement these surface supplies. There are 11 surface
   water treatment plants.
o  Ohio - Water supply is obtained for customers in Lake County from Lake Erie.
   Customers in Mahoning County obtain their water from man-made lakes and the
   Ashtabula division is supplied by purchased water obtained through an
   interconnection with an adjacent water utility. Water supply is obtained for
   customers in Stark and Summit counties from wells. In Trumbull County,
   customers are served through an interconnection from our Pennsylvania
   division.
o  North Carolina - Water supply in 747 non-contiguous divisions is obtained
   principally from wells, with several divisions purchasing water from
   neighboring municipalities.
o  Illinois - Water supply is obtained for customers in Kankakee County from the
   Kankakee River and satellite wells, while customers in Vermilion County are
   supplied from Lake Vermilion. In Will, Lee, Boone, Lake and Knox counties,
   our customers are served from wells. In some areas, water supply is
   supplemented with purchased water obtained through interconnections with
   adjacent water utilities.
o  Texas - Water supply in 295 non-contiguous water systems is obtained
   principally from wells, supplemented in some cases by purchased water from
   adjacent surface water systems.

                                       6

o  Florida - Water supply in the majority of the 70 non-contiguous divisions is
   obtained principally from wells, supplemented in some cases by purchased
   water from adjacent surface water systems.
o  New Jersey - Water supply is obtained principally from wells and the supply
   is supplemented with purchased water obtained through interconnections with
   adjacent water utilities.
o  Indiana - Water supply in three water systems is obtained principally from
   wells.
o  Virginia - Water supply in 127 non-contiguous divisions is obtained from
   wells, one division's supply is from surface water, and four divisions
   supplement their supply with purchased water from a nearby water system.
o  Maine - Eleven non-contiguous water systems obtain their water supply as
   follows: six systems use groundwater, four systems use surface water and one
   system purchases water from a neighboring municipal district.

We believe that the capacities of our sources of supply, and our water
treatment, pumping and distribution facilities are generally sufficient to meet
the present requirements of our customers under normal conditions. We plan
system improvements and additions to capacity in response to changing regulatory
standards, changing patterns of consumption and increased demand from a growing
number of customers. The various state public utility commissions have generally
recognized the operating and capital costs associated with these improvements in
setting water rates.

On occasion, drought warnings and water use restrictions are issued by
governmental authorities for portions of our service territories in response to
extended periods of dry weather conditions. The timing and duration of the
warnings and restrictions can have an impact on our water revenues and net
income. In general, water consumption in the summer months is affected by
drought warnings and restrictions to a higher degree because nonessential and
recreational use of water is at its highest during the summer months. At other
times of the year, warnings and restrictions generally have less of an effect on
water consumption.

We believe that our wastewater treatment facilities are generally adequate to
meet the present requirements of our customers. In addition, we own several
sewer collection systems where the wastewater is treated at a municipally-owned
facility. Capital funds are included in our capital plans to address inflow and
infiltration in the collection systems, and wet weather flows at our lift
stations and treatment plants, and other conditions and requirements that can
affect compliance. Changes in regulatory requirements may be reflected in
revised permit limits and conditions when National Pollution Discharge
Elimination System ("NPDES") permits are renewed, typically on a five-year
cycle. Capital improvements are planned and budgeted to meet anticipated changes
in regulations and needs for increased capacity related to projected growth. The
various state public utility commissions have generally recognized the operating
and capital costs associated with these improvements in setting wastewater rates
for current customers and capacity charges for new customers.

Economic Regulation

Most of our water and wastewater utility operations are subject to regulation by
their respective state regulatory commissions, which have broad administrative
power and authority to regulate rates and charges, determine franchise areas and
conditions of service, approve acquisitions and authorize the issuance of
securities. The regulatory commissions also establish uniform systems of
accounts and approve the terms of contracts with affiliates and customers,
business combinations with other utility systems, loans and other financings,
and the franchise areas that we serve. A small number of our operations are
subject to rate regulation by county or city governments. The profitability of
our utility operations is influenced to a great extent by the timeliness and
adequacy of rate allowances we are granted by the respective regulatory
commissions or authorities in the various states in which we operate.

                                       7

Accordingly, we maintain a rate case management capability to provide that the
tariffs of our utility operations reflect, to the extent practicable, the timely
recovery of increases in costs of operations, capital, taxes, energy, materials
and compliance with environmental regulations. We file rate increase requests to
recover the capital investments that we make in improving or replacing our
facilities and to recover expenses. In the states in which we operate, we are
subject to economic regulation by the following state regulatory commissions:

         State                      Regulatory Commission
         -----                      ---------------------
         Pennsylvania               Pennsylvania Public Utility Commission

         New York                   New York Public Service Commission
         South Carolina             South Carolina Public Service Commission

Some of the states in which we acquired operations in 2004 and 2003 require
separate rate filings for each of our local systems, as compared to a single
state-wide rate filing. Between August 2003 and December 2005, we filed or were
preparing to file rate filings in over 25 jurisdictions. Due to the length of
time since the last rate increase for some acquired systems and the large amount
of capital improvements relative to the number of customers in some smaller
systems, the proposed rate increase in some of these systems may be substantial.
While each of these rate filings will proceed through the applicable regulatory
process, we can provide no assurance that the rate increases will be granted in
a timely or sufficient manner to cover the investments and expenses for which we
initially sought the rate increases. Further, there remains 116 divisions within
these recently acquired operations where we have not yet filed a rate request.

We are currently consolidating our customer service locations into three
principal call centers, implementing a common customer information system, and
upgrading our financial information systems. We expect to complete our primary
customer service initiatives by the end of 2006. Consistent with prior practice,
we have capitalized costs and services associated with the projects and expect
to recover these costs in future rates. Although we believe it is probable that
the applicable public utility commissions will allow recovery of these costs, we
can provide no assurances as to their full recoverability until the conclusion
of the applicable rate proceeding.

Five states in which we operate permit water utilities, and in some states
wastewater utilities, to add a surcharge to their water or wastewater bills to
offset the additional depreciation and capital costs associated with certain
capital expenditures related to replacing and rehabilitating infrastructure
systems. Prior to these mechanisms being approved, water and wastewater
utilities absorbed all of the depreciation and capital costs of these projects
between base rate increases without the benefit of additional revenues. The gap
between the time that a capital project is completed and the recovery of its
costs in rates is known as regulatory lag. The infrastructure rehabilitation
surcharge mechanism is intended to substantially reduce regulatory lag, which
often acted as a disincentive to water and wastewater utilities to rehabilitate
their infrastructure. In addition, our subsidiaries in certain states use a
surcharge or credit on their bill to reflect changes in certain costs, such as
changes in state tax rates, until such time as the costs are incorporated into
base rates.

Currently, Pennsylvania, Illinois, Ohio, Indiana and Missouri allow for the use
of infrastructure rehabilitation surcharges. These mechanisms typically adjust
periodically based on additional qualified capital expenditures completed or
anticipated in a future period. The infrastructure rehabilitation surcharge is
capped at a percentage of base rates, generally at 5% to 9% of base rates, and
is reset to zero when new base rates that reflect the costs of those additions
become effective or when a utility's earnings exceed a regulatory benchmark.
Infrastructure rehabilitation surcharges provided revenues of $10,186,000 in
2005, $7,817,000 in 2004 and $8,147,000 in 2003.

                                       8

In general, we believe that Aqua America, Inc. and its subsidiaries have valid
authority, free from unduly burdensome restrictions, to enable us to carry on
our business as presently conducted in the franchised or contracted areas we now
serve. The rights to provide water or wastewater service to a particular
franchised service territory are generally non-exclusive, although the
applicable regulatory commissions usually allow only one regulated utility to
provide service to a given area. In some instances, another water utility
provides service to a separate area within the same political subdivision served
by one of our subsidiaries.

In the states where our subsidiaries operate, it is possible that portions of
our subsidiaries' operations could be acquired by municipal governments by one
or more of the following methods:

o  eminent domain;
o  the right of purchase given or reserved by a municipality or political
   subdivision when the original franchise was granted; and
o  the right of purchase given or reserved under the law of the state in which
   the subsidiary was incorporated or from which it received its permit.

The price to be paid upon such an acquisition by the municipal government is
usually determined in accordance with applicable law governing the taking of
lands and other property under eminent domain. In other instances, the price may
be negotiated, fixed by appraisers selected by the parties or computed in
accordance with a formula prescribed in the law of the state or in the
particular franchise or charter. We believe that our operating subsidiaries will
be entitled to fair market value for any assets that are condemned, and we
believe the fair market value will be in excess of the book value for such
assets.

In December 2004, as a result of the settlement of a condemnation action, our
Ohio operating subsidiary sold its water utility assets within the municipal
boundaries of the City of Geneva in Ashtabula County, Ohio for net proceeds of
approximately $4,716,000, which was in excess of the book value for these
assets. The sale resulted in the recognition in the fourth quarter of 2004 of a
pre-tax gain on the sale of these assets, net of expenses, of $2,342,000. We
continue to operate this water system for the City of Geneva under an operating
contract that began upon the closing of the sale for a period through December
2006. These water utility assets represent less than 1% of Aqua America's total
assets, and the total number of customers included in the water system sold
represents less than 1% of our total customer base. The increase in earnings
associated with reinvesting the sale's proceeds and the operating income
generated by the operating contract has offset the loss of this water system's
historic contribution to income.

The City of Fort Wayne, Indiana has authorized the acquisition, by eminent
domain or otherwise, of a portion of the utility assets of one of the operating
subsidiaries that we acquired in connection with the AquaSource acquisition in
2003. We have challenged whether the City is following the correct legal
procedures in connection with the City's attempted condemnation and we have
challenged the City's valuation of this portion of our system. The portion of
the system under consideration represents approximately 1% of our total customer
base. While we continue to discuss this matter with officials from the City of
Fort Wayne, we continue to protect our interests in this proceeding.

Despite the sales and possible condemnation referred to above, our strategy
continues to be to acquire additional water and wastewater systems, maintain our
existing systems, and actively oppose efforts by municipal governments to
acquire any of our operations, particularly for less than the fair market value
of our operations or where the municipal government seeks to acquire more than
it is entitled to under the applicable law or agreement.

                                       9

Environmental, Health and Safety Regulation

Provision of water and wastewater services is subject to regulation under the
federal Safe Drinking Water Act, the Clean Water Act and related state laws, and
under federal and state regulations issued under these laws. These laws and
regulations establish criteria and standards for drinking water and for
wastewater discharges. In addition, we are subject to federal and state laws and
other regulations relating to solid waste disposal, dam safety and other
operations. Capital expenditures and operating costs required as a result of
water quality standards and environmental requirements have been traditionally
recognized by state public utility commissions as appropriate for inclusion in
establishing rates.

Environmental compliance issues remain at various water and wastewater
facilities associated with acquired systems, including facilities acquired in
connection with the AquaSource acquisition that was completed in 2003, the
Heater and Florida Water Service acquisitions completed in 2004 and the
acquisitions of small utilities in Northeastern Pennsylvania. We believe that
the capital expenditures required to address these compliance issues have been
budgeted in our capital program and represent less than 10% of our expected
total capital expenditures over the next five years. We are parties to
agreements with regulatory agencies in Texas, Florida, Indiana, Virginia and
North Carolina under which we have committed to make certain improvements for
environmental compliance. These agreements are intended to provide the
regulators with assurance that problems covered by these agreements will be
addressed, and the agreements generally provide protection to us from fines,
penalties and other actions while corrective measures are being implemented. We
are actively working directly with state environmental officials to implement or
amend these agreements as necessary.

Safe Drinking Water Act - The Safe Drinking Water Act establishes criteria and
procedures for the U.S. Environmental Protection Agency to develop national
quality standards for drinking water. Regulations issued pursuant to the Safe
Drinking Water Act and its amendments set standards on the amount of certain
microbial and chemical contaminants and radionuclides allowable in drinking
water. Current requirements under the Safe Drinking Water Act are not expected
to have a material impact on our operations or financial condition as we have
made and are making investments to meet existing water quality standards. We
may, in the future, be required to change our method of treating drinking water
at certain sources of supply if additional regulations become effective.

The EPA's issuance of a rule regulating radon in tap water has been postponed
repeatedly since 1991. Limits for radon in tap water, if promulgated, would
probably become effective 4 or 5 years after promulgation and would likely
contain two standards to recognize cost-effective alternative approaches to
dealing with radon in indoor air. We anticipate that the higher level
established by such a rule might require treatment at a small percentage of our
wells, primarily in North Carolina, Pennsylvania and Virginia. If the states in
which we operate elect not to implement general radon reduction (Multi-Media
Mitigation) programs, then a more stringent limit for radon could apply and a
larger number of wells would be affected. We anticipate that states will adopt
Multi-Media Mitigation programs, and the capital costs to comply with this
future regulation could approximate $4,000,000 over a five year period.

The Safe Drinking Water Act provides for the regulation of radionuclides other
than radon, such as radium and uranium. The Radionuclides Rule that became
effective in December 2003 left unchanged the existing standards for gross alpha
and radium, but changed the monitoring protocol. The rule also added a maximum
contaminant level for uranium. Under the new testing protocols, some of our
smaller groundwater facilities have exceeded one or more of the radionuclide
standards and require treatment by January 2008. Treatment processes have
already been installed at twelve facilities, and approximately twenty additional
facilities will require the installation of a treatment process, replacement or
modification of a well, or other remedy. The future capital cost of compliance
is expected to be less than $5,000,000. The impact of the rulemaking is not
expected to have a material impact on our results of operations or financial
condition.

                                       10

In order to remove or inactivate microbial organisms, rules were issued by the
EPA to improve disinfection and filtration of potable water and reduce
consumers' exposure to disinfectants and by-products of the disinfection
process. In the future, we may be required to install filtration or other
treatment, for one currently unfiltered surface water supply. The cost of this
treatment, should it be required, is not expected to exceed $5,000,000. Certain
small groundwater systems could be reclassified as being influenced by surface
water. This may require additional treatment or the development of replacement
sources of supply over time, the cost for which is not expected to exceed a
total of $1,000,000. In addition, ten small systems in Florida were recently
found to have trihalomethanes above the current maximum contaminant level.
Treatment modifications are being planned that may require capital costs of
approximately $1,500,000 over the next two years.

The EPA promulgated the Long Term 2 Enhanced Surface Water Treatment Rule and a
Stage 2 Disinfection/Disinfection By-product Rule in January 2006. These rules
will result in additional one-time special monitoring costs of approximately
$600,000 over a four-year period from 2006 to 2010. The results of the
monitoring might require modification of treatment, including capital
improvements, in year 2008 and beyond. It is not possible at this time to
reasonably project the potential impact on the capital budget, if any, from
these rules, but the impact is not expected to have a material impact on our
results of operations or financial condition.

A rule lowering the limit on arsenic was promulgated in 2001 and becomes
effective in January 2006, with a provision for further time extensions for
small systems. The rule will require installation of treatment or development of
alternative supplies at a very limited number of our groundwater sources. The
largest of these, in Pennsylvania, was equipped with treatment in 2004. A small
system in Maine was equipped with treatment in 2005. One system each in Texas
and Ohio will require treatment in 2006, and one system in North Carolina will
require treatment or replacement of a currently unused back-up well. The cost of
these remaining capital improvements to fully achieve compliance with this
regulation is not expected to exceed $500,000.

In 2000, the gasoline additive Methyl tert-Butyl Ether ("MtBE") was discovered
in a production well in one of our operating subsidiaries at levels exceeding
the state drinking water standard. The well was immediately taken out of service
and alternate water supplies were obtained. A legal settlement was reached in
2004 with the company believed to be responsible for the contamination and we
received a settlement amount of $2,000,000 to cover the cost of a permanent
replacement well, which was completed and placed in service in 2004, and to
cover our interim purchased water costs incurred. Traces of MtBE may be found
throughout the environment as the result of extensive use of MtBE as a gasoline
additive.

Clean Water Act - The Clean Water Act regulates discharges from drinking water
and wastewater treatment facilities into lakes, rivers, streams, and
groundwater. It is our policy to obtain and maintain all required permits and
approvals for the discharges from our water and wastewater facilities, and to
comply with all conditions of those permits and other regulatory requirements. A
program is in place to monitor facilities for compliance with permitting,
monitoring and reporting for wastewater discharges. From time to time, discharge
violations may occur which may result in fines. We are also parties to
compliance agreements with regulatory agencies in several states where we
operate while improvements are being made to address wastewater discharge
compliance issues. These fines and penalties, if any, are not expected to have a
material impact on our results of operations or financial condition. The
required costs to comply with the agreements previously cited are included in
our capital program, are not expected to be significant, and are expected to be
recoverable in rates.

Recent changes in wastewater regulations in the state of Missouri will require
improvements at certain of the 52 small wastewater systems we operate in that
state. We presently estimate the cost of these improvements to be approximately
$1,500,000 over the next three years.

                                       11

Solid Waste Disposal - The handling and disposal of residuals and solid waste
generated from water and wastewater treatment facilities is governed by federal
and state laws and regulations. A program is in place to monitor our facilities
for compliance with regulatory requirements, and we do not currently anticipate
any major expenditures in connection with the handling and disposal of waste
material from our water and wastewater operations.

Dam Safety - Our subsidiaries own seventeen major dams that are subject to the
requirements of the Federal and state regulations related to dam safety. All
major dams undergo an annual engineering inspection. We believe that all
seventeen dams are structurally sound and well-maintained.

In Pennsylvania, the Department of Environmental Protection has adopted the use
of a revised formula for determining the magnitude of a probable maximum flood.
We have studied our dams to determine what improvements may be needed as a
result of this new calculation. Our initial studies identified three dams in
Pennsylvania that could require capital improvements; however, further study
reduced this to two dams needing improvements of approximately $6,000,000 in the
aggregate. Our findings have been accepted by the Department of Environmental
Protection, and design is underway for both dam improvement projects.
Construction is anticipated to be completed over the next three years, and we
believe that these capital expenditures will be recoverable in our rates.
Similarly, in Ohio, the Department of Natural Resources has adopted the use of a
revised formula. We have studied our dams in Ohio and determined that three of
the dams will require improvements. Construction began in 2005 on one of these
dams, and we believe that capital expenditures of approximately $4,600,000 in
the aggregate will be required on these dams over the next four years.

Safety Standards - Our facilities and operations may be subject to inspections
by representatives of the Occupational Safety and Health Administration from
time to time. We maintain safety policies and procedures to comply with the
Occupational Safety and Health Administration's rules and regulations, but
violations may occur from time to time, which may result in fines and penalties,
which are not expected to be material. We endeavor to correct such violations
promptly after they are brought to our attention.

Security

In light of concerns regarding security in the wake of the September 11, 2001
terrorist attacks, we have increased security measures at our facilities. These
increased security measures were not made in response to any specific threat. We
are in contact with federal, state and local authorities and industry trade
associations regarding information on possible threats and security measures for
water utility operations. The cost of the increased security measures, including
capital expenditures, is expected to be recoverable in water rates and is not
expected to have a material impact on our results of operations or financial
condition.

Employee Relations

As of December 31, 2005, we employed a total of 1,489 full-time employees. Our
subsidiaries are parties to 10 agreements with labor unions covering 428
employees that expire at various times between March 2006 and May 2009. One of
the agreements, representing 275 employees, expires in December 2006 and five
additional contracts, representing 91 employees, expire at various other times
in 2006.

Item 1A. Risk Factors

In addition to the other information included in this Report, the following
factors should be considered in evaluating our business and future prospects.
Any of the following risks, either alone or taken together, could materially and
adversely affect our business, financial position or results of operations. If
one or more of these or other risks or uncertainties materialize, or if our
underlying assumptions prove to be incorrect, our actual results may vary
materially from what we projected. There may be additional risks that we do not
presently know or that we currently believe are immaterial which could also
impair our business or financial position.

OUR BUSINESS REQUIRES SIGNIFICANT CAPITAL EXPENDITURES AND THE RATES WE CHARGE
OUR CUSTOMERS ARE SUBJECT TO REGULATION. IF WE ARE UNABLE TO OBTAIN SUFFICIENT
CAPITAL ON REASONABLE TERMS OR OBTAIN GOVERNMENT APPROVAL OF OUR REQUESTS FOR
RATE INCREASES, OR IF APPROVED RATE INCREASES ARE UNTIMELY OR INADEQUATE TO
COVER OUR CAPITAL INVESTMENTS AND TO RECOVER EXPENSES, OUR PROFITABILITY MAY
SUFFER.

The water utility business is capital intensive. In addition to the capital
required to fund our growth through acquisition strategy, on an annual basis, we
spend significant sums for additions to or replacement of property, plant and
equipment. Our ability to maintain and meet our financial objectives is
dependent upon the availability of adequate capital and the recovery of our
capital investments through the rates we charge our customers. There is no
guarantee that we will be able to obtain sufficient capital in the future on
reasonable terms and conditions for expansion, construction and maintenance. In
the event we are unable to obtain sufficient capital, our expansion efforts
could be curtailed, which may affect our growth and may affect our future
results of operations. The rates we charge our customers are subject to approval
by the public utility commissions or similar regulatory bodies in the states in
which we operate. We file rate increase requests, from time to time, to recover
our investments in utility plant and expenses. Once a rate increase petition is
filed with a public utility commission, the ensuing administrative and hearing
process may be lengthy and costly. The timing of our rate increase requests are
therefore partially dependent upon the estimated cost of the administrative
process in relation to the investments and expenses that we hope to recover
through the rate increase to the extent approved. We can provide no assurances
that any future rate increase request will be approved by the appropriate state
public utility commission; and, if approved, we cannot guarantee that these rate
increases will be granted in a timely or sufficient manner to cover the
investments and expenses for which we initially sought the rate increase.

OUR OPERATING COSTS COULD BE SIGNIFICANTLY INCREASED IN ORDER TO COMPLY WITH NEW
OR STRICTER REGULATORY STANDARDS IMPOSED BY FEDERAL AND STATE ENVIRONMENTAL
AGENCIES.

Our water and wastewater services are governed by various federal and state
environmental protection and health and safety laws and regulations, including
the federal Safe Drinking Water Act, the Clean Water Act and similar state laws,
and federal and state regulations issued under these laws by the United States
Environmental Protection Agency and state environmental regulatory agencies.
These laws and regulations establish, among other things, criteria and standards
for drinking water and for discharges into the waters of the United States and
states. Pursuant to these laws, we are required to obtain various environmental
permits from environmental regulatory agencies for our operations. We cannot
assure you that we have been or will be at all times in total compliance with
these laws, regulations and permits. If we violate or fail to comply with these
laws, regulations or permits, we could be fined or otherwise sanctioned by
regulators. Environmental laws and regulations are complex and change
frequently. These laws, and the enforcement thereof, have tended to become more
stringent over time. While we have budgeted for future capital and operating
expenditures to maintain compliance with these laws and our permits, it is
possible that new or stricter standards could be imposed that will raise our
operating costs. Although these costs may be recovered in the form of higher
rates, there can be no assurance that the various state public utility
commissions or similar regulatory bodies that govern our business would approve
rate increases to enable us to recover such costs. In summary, we cannot assure
you that our costs of complying with, or discharging liability under, current
and future environmental and health and safety laws will not adversely affect
our business, results of operations or financial condition.

                                       14

OUR BUSINESS IS SUBJECT TO SEASONAL FLUCTUATIONS, WHICH COULD AFFECT DEMAND FOR
OUR WATER SERVICE AND OUR REVENUES.

Demand for our water during the warmer months is generally greater than during
cooler months due primarily to additional requirements for water in connection
with irrigation systems, swimming pools, cooling systems and other outside water
use. Throughout the year, and particularly during typically warmer months,
demand will vary with temperature and rainfall levels. In the event that
temperatures during the typically warmer months are cooler than normal, or if
there is more rainfall than normal, the demand for our water may decrease and
adversely affect our revenues.

DROUGHT CONDITIONS MAY IMPACT OUR ABILITY TO SERVE OUR CURRENT AND FUTURE
CUSTOMERS, AND MAY IMPACT OUR CUSTOMERS' USE OF OUR WATER, WHICH MAY ADVERSELY
AFFECT OUR FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

We depend on an adequate water supply to meet the present and future demands of
our customers. Drought conditions could interfere with our sources of water
supply and could adversely affect our ability to supply water in sufficient
quantities to our existing and future customers. An interruption in our water
supply could have a material adverse effect on our financial condition and
results of operations. Moreover, governmental restrictions on water usage during
drought conditions may result in a decreased demand for our water, even if our
water reserves are sufficient to serve our customers during these drought
conditions, which may adversely affect our revenues and earnings.

AN IMPORTANT ELEMENT OF OUR GROWTH STRATEGY IS THE ACQUISITION OF WATER AND
WASTEWATER SYSTEMS. ANY FUTURE ACQUISITIONS WE DECIDE TO UNDERTAKE MAY INVOLVE
RISKS.

An important element of our growth strategy is the acquisition and integration
of water and wastewater systems in order to broaden our current, and move into
new, service areas. We will not be able to acquire other businesses if we cannot
identify suitable acquisition opportunities or reach mutually agreeable terms
with acquisition candidates. It is our intent, when practical, to integrate any
businesses we acquire with our existing operations. The negotiation of potential
acquisitions as well as the integration of acquired businesses could require us
to incur significant costs and cause diversion of our management's time and
resources. Future acquisitions by us could result in:

         o  dilutive issuances of our equity securities;
         o  incurrence of debt and contingent liabilities;
         o  failure to have effective internal control over financial reporting;
         o  fluctuations in quarterly results; and
         o  other acquisition-related expenses.

Some or all of these items could have a material adverse effect on our business
and our ability to finance our business and comply with regulatory requirements.
The businesses we acquire in the future may not achieve sales and profitability
that would justify our investment, and any difficulties we encounter in the
integration process, including in the integration of controls necessary for
internal control and financial reporting, could interfere with our operations,
reduce our operating margins and adversely affect our internal controls. In
addition, as consolidation becomes more prevalent in the water and wastewater
industries, the prices for suitable acquisition candidates may increase to
unacceptable levels and limit our ability to grow through acquisitions.

                                       15

CONTAMINATION TO OUR WATER SUPPLY MAY RESULT IN DISRUPTION IN OUR SERVICES AND
LITIGATION WHICH COULD ADVERSELY AFFECT OUR BUSINESS, OPERATING RESULTS AND
FINANCIAL CONDITION.

Our water supplies are subject to contamination, including contamination from
the development of naturally-occurring compounds, chemicals in groundwater
systems, pollution resulting from man-made sources, such as MtBE, and possible
terrorist attacks. In the event that our water supply is contaminated, we may
have to interrupt the use of that water supply until we are able to substitute
the flow of water from an uncontaminated water source. In addition, we may incur
significant costs in order to treat the contaminated source through expansion of
our current treatment facilities, or development of new treatment methods. If we
are unable to substitute water supply from an uncontaminated water source, or to
adequately treat the contaminated water source in a cost-effective manner, there
may be an adverse effect on our revenues, operating results and financial
condition. The costs we incur to decontaminate a water source or an underground
water system could be significant and could adversely affect our business,
operating results and financial condition and may not be recoverable in rates.
We could also be held liable for consequences arising out of human exposure to
hazardous substances in our water supplies or other environmental damage. For
example, private plaintiffs have the right to bring personal injury or other
toxic tort claims arising from the presence of hazardous substances in our
drinking water supplies. Our insurance policies may not be sufficient to cover
the costs of these claims.

In addition to the potential pollution of our water supply as described above,
in the wake of the September 11, 2001 terrorist attacks and the ensuing threats
to the nation's health and security, we have taken steps to increase security
measures at our facilities and heighten employee awareness of threats to our
water supply. We have also tightened our security measures regarding the
delivery and handling of certain chemicals used in our business. We have and
will continue to bear increased costs for security precautions to protect our
facilities, operations and supplies. These costs may be significant. Despite
these tightened security measures, we may not be in a position to control the
outcome of terrorist events should they occur.

WASTEWATER OPERATIONS MAY ENTAIL SIGNIFICANT RISKS.

Wastewater collection and treatment involve many risks associated with damage to
the surrounding environment. If collection or treatment systems fail or do not
operate properly, untreated or partially treated wastewater could discharge onto
property or into nearby streams and rivers, causing property damage or injury to
aquatic life, or even human life. Liabilities resulting from such damage could
materially and adversely affect the Company's results of operations and
financial condition.

WORK STOPPAGES AND OTHER LABOR RELATIONS MATTERS COULD ADVERSELY AFFECT OUR
OPERATING RESULTS.

Approximately 33% of our workforce, are unionized under ten labor contracts (or
contracts under negotiation) with labor unions, which expire over several years.
We believe our labor relations are good, but in light of rising costs for
healthcare and pensions, contract negotiations in the future may be difficult.
We are subject to a risk of work stoppages and other labor relations matters as
we negotiate with the unions to address these issues, which could affect the
Company's results of operations and financial condition. We cannot assure you
that issues with our labor forces will be resolved favorably to us in the future
or that we will not experience work stoppages.

WE DEPEND SIGNIFICANTLY ON THE SERVICES OF THE MEMBERS OF OUR MANAGEMENT TEAM,
AND THE DEPARTURE OF ANY OF THOSE PERSONS COULD CAUSE OUR OPERATING RESULTS TO
SUFFER.

Our success depends significantly on the continued individual and collective
contributions of our management team. The loss of the services of any member of
our management team or the inability to hire and retain experienced management
personnel could harm our operating results.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Our properties consist of transmission and distribution mains and conduits,
water and wastewater treatment plants, pumping facilities, wells, tanks, meters,
supply lines, dams, reservoirs, buildings, vehicles, land, easements, rights and
other facilities and equipment used for the operation of our systems, including
the collection, treatment, storage and distribution of water and the collection
and treatment of wastewater. Substantially all of our properties are owned by
our subsidiaries, and a substantial portion of our property is subject to liens
of mortgage or indentures. These liens secure bonds, notes and other evidences
of long-term indebtedness of our subsidiaries. For certain properties that we
acquired through the exercise of the power of eminent domain and certain other
properties we purchased, we hold title for water supply purposes only. We own,
operate and maintain several thousand miles of transmission and distribution
mains, 23 water treatment plants, and many well treatment stations and
wastewater treatment plants. Some properties are leased under long-term leases.
The following table indicates our net property, plant and equipment, in

accordance with current standards of good waterworks industry practice. We
believe that the facilities used in the operation of our business are in good
condition in terms of suitability, adequacy and utilization.

Our corporate offices are leased from Aqua Pennsylvania, Inc. and located in
Bryn Mawr, Pennsylvania.

Item 3. Legal Proceedings

There are various legal proceedings in which we are involved. Although the
results of legal proceedings cannot be predicted with certainty, there are no
pending legal proceedings to which we or any of our subsidiaries is a party or
to which any of our properties is the subject that are material or are expected
to have a material effect on our financial position, results of operations or
cash flows.

Item 4. Submission of Matters to a Vote of Security Holders

We have paid common dividends consecutively for 61 years. Effective December 1,
2005, our Board of Directors authorized an increase of 9.6% in the dividend rate
over the amount Aqua America, Inc. paid in the previous quarter. As a result of
this authorization, beginning with the dividend payment in December 2005, the
annualized dividend rate increased to $0.4276 per share. We presently intend to
pay quarterly cash dividends in the future, on March 1, June 1, September 1 and
December 1, subject to our earnings and financial condition, regulatory
requirements and such other factors as our Board of Directors may deem relevant.
During the past five years, our common dividends paid have averaged 56.3% of net
income.

In August 2005, our Board of Directors declared a 4-for-3 common stock split
effected in the form of a 33 1/3 % stock distribution for all common shares
outstanding, to shareholders of record on November 17, 2005. The new shares were
distributed on December 1, 2005. All share and per share data for all periods
presented have been restated to give effect to the stock split.

(1) These amounts consist of 10,656 shares we purchased from shareholders for
the fractional shares that would otherwise be issued in connection with the
December 1, 2005 stock split, and shares we purchased from our employees who
elected to pay the exercise price of their stock options (and then hold shares
of the stock) upon exercise by delivering to us (and, thus, selling) shares of
Aqua America common stock in accordance with the terms of our equity
compensation plans that were previously approved by our shareholders and
disclosed in our proxy statements. This feature of our equity compensation plan
is available to all employees who receive option grants under the plan and these
shares are purchased at their fair market value, as determined by reference to
the closing price of our common stock on the day prior to the option exercise.

(2) On August 5, 1997, our Board of Directors authorized a common stock
repurchase program that was publicly announced on August 7, 1997, for up to
1,007,351 shares. No repurchases have been made under this program since 2000.
The program has no fixed expiration date. The number of shares authorized for
purchase was adjusted as a result of the stock splits effected in the form of
stock distributions since the authorization date.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are subject to market risks in the normal course of business, including
changes in interest rates and equity prices. The exposure to changes in interest
rates is a result of financings through the issuance of fixed-rate, long-term
debt. Such exposure is typically related to financings between utility rate
increases, since generally our rate increases include a revenue level to allow
recovery of our current cost of capital. Interest rate risk is managed through
the use of a combination of long-term debt, which is at fixed interest rates and
short-term debt, which is at floating interest rates. As of December 31, 2005,
the debt maturities by period, in thousands of dollars, and the weighted average
interest rate for fixed-rate, long-term debt are as follows:


                                                                                                                Fair

Item 9A. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures - Our management, with the
participation of our Chief Executive Officer and Chief Financial Officer,
evaluated the effectiveness of our disclosure controls and procedures as of the
end of the period covered by this report. Based on that evaluation, the Chief
Executive Officer and Chief Financial Officer concluded that our disclosure
controls and procedures as of the end of the period covered by this report are
effective to provide reasonable assurance that the information required to be
disclosed by us in reports filed under the Securities Exchange Act of 1934 is
(i) recorded, processed, summarized and reported within the time periods
specified in the SEC's rules and forms and (ii) accumulated and communicated to
our management, including the Chief Executive Officer and Chief Financial
Officer, as appropriate to allow timely decisions regarding disclosure. A
controls system cannot provide absolute assurance, however, that the objectives
of the controls system are met, and no evaluation of controls can provide
absolute assurance that all control issues and instances of fraud, if any,
within a company have been detected.
