Protecting Source Water with the
Clean Water State Revolving Fund

Protecting sources of drinking water through
infrastructure investment not only safeguards the
water we rely on, it also can save communities money.
By managing potential sources of contamination
and preventing pollutants from reaching sources of
drinking water, communities may avoid the need for
additional drinking water treatment, thereby reducing
treatment costs. Low-cost financing from the Clean
Water State Revolving Fund (CWSRF) is available for
source water protection activities and can amplify
these savings for communities and their water users.

The CWSRF is a federal-state partnership that offers
flexibility to finance a broad range of projects that
address states' highest priority water quality needs.
The programs in each state and Puerto Rico operate
iike banks. Federal and state contributions are
used to capitalize the programs, and these funds
are distributed as low-interest loans for projects
that improve water quality and help protect the
environment and public health. Funds are then repaid
to the CWSRF and used to finance additional projects.

CWSRF ASSISTANCE FOR SOURCE WATER

CWSRF financing is available to public, private, or
nonprofit entities for many types of source water pro-
tection (SWP) projects, including both green and grey
infrastructure water quality solutions for both surface
water and groundwater.

CWSRF-eligible source water protection projects
include:

•	Land conservation

•	Easements, leasing, and fee simple purchase of
land

•	Agricultural best management practices

•	Cropland and livestock

•	Decentralized wastewater treatment

•	Septic tank repair or replacement

•	Remediation or prevention of contamination from
resource extraction sites

•	Habitat restoration

•	Shoreline/riparian buffers

•	Stormwater management

•	Contaminated site clean-up

•	Wildfire risk management

•	Development and updates of source water
protection plans

LOAN REPAYMENT OPTIONS

CWSRFs can offer a variety of types of financial
assistance. Potential CWSRF borrowers must identify
a dedicated repayment source, which need not come
from the project itself, before a loan is approved.
Finding a source of repayment for source water
protection projects may prove challenging.

Some potential repayment sources include:

Recreational fees (e.g., fishing licenses, entrance
fees);

Dedicated portions of local, county, or state taxes
or fees;

Stormwater utility fees;

Fees paid by developers;

Donations or dues made to nonprofit
organizations;

Individual or business revenues;

Revenue from sustainable timber harvest or other
forest products;

Carbon and/or nutrient credits; and
Downstream water users.

CWSRF FINANCIAL BENEFITS

CWSRF assistance options deliver significant
benefits to prospective borrowers. Incentives may
vary by state program. CWSRF loans can provide
the following benefits:

•	Coverage of up to 100 percent of project costs;

•	Deeply discounted loans that are well below
the market rate down to zero percent;

•	Access to additional subsidies such as loan
forgiveness;

•	Deferred payments of principal and/or interest;

•	Terms up to 30 years and extended term
financing that reduces annual interest payments;

•	Dedicated revenues for loan repayments that
can come from any source;

•	Low-cost project financing and reliable access
to capital through the use of programmatic and
portfolio financing options;

•	Access to co-financing opportunities;

•	Credit enhancements that lower the cost
of borrowing for less than AAA green debt
obligations; and

•	Access to affordable assistance for technical
assistance, project development, and planning.

Because source water protection projects may not
have associated available income streams, states use
a variety of financing mechanisms for these projects.

While direct lending is one option, many states have
used innovative partnership models to facilitate
coordination and funding support for regional

solutions to water quality problems. These additional options include sponsorship lending, intermunicipal and
intermediary lending, and watershed partnership programs, among others. For more information on these
financing mechanisms, please reference "Financing Options for Nontraditional Eligibilities in the Clean Water
State Revolving Fund Programs." on EPA's website.

LEVERAGING CWSRF FUNDS

CWSRF funds can be leveraged with other funding programs that protect and improve freshwater resources
and public health. For example, several states have used funds from their Drinking Water State Revolving
Fund (DWSRF) set-asides to develop source water assessments, appraisals, and plans to meet application
requirements for CWSRF loans and Clean Water Act Section 319 Nonpoint Source (NPS) Management grants.
In some states, CWSRF repayment funds are used by borrowers to match other federal grants, like Section 319
NPS management grants, to help initiate projects.

LEARN MORE ABOUT FUNDING

CWSRF programs are managed by the states and assistance is distributed directly from state agencies. The
procedures and funding of eligible projects may vary according to the priorities of each state.

Contact information for each program's states is posted at: https://www.epa.gov/cwsrf/state-cwsrf-program-
contacts.

CWSRF SOURCE WATER PROTECTION CASE STUDIES

ARIZONA'S CWSRF FOREST THINNING AND
RESTORATION PROGRAM
Forest thinning and fire prevention are investments
in a community's health, not unlike investments in a
water or wastewater treatment facility. Responding
to contamination can be as much as 200 times
more expensive as preventing the pollution of
drinking water resources. Using conservation
forestry practices, like forest thinning, helps stabilize
watershed vegetation in the understory and prevent
erosion, which protects water quality.

The Flagstaff Watershed Protection Project is a
partnership between the City of Flagstaff, the Water
Infrastructure Finance Authority of Arizona (WIFA),
which administers the CWSRF program, and the
Coconino National Forest to help reduce the risk of
devastating wildfire and post-fire flooding in the Rio
de Flag and Lake Mary Watersheds.

After the Schultz Fire consumed over 15,000 acres
of forest outside of Flagstaff, and resulted in $147
million in damage, the city voted to support a bond
measure to fund large-scale projects to thin forests
and undertake better vegetation management
practices on city, state, tribal, and federal lands. This
was the first time the city considered a nonpoint
source project of this kind to be part of a Capital
Improvement Plan and included in their water
infrastructure budget. In addition to the proceeds
from the bond measure, the city received a $6 million
WIFA CWSRF loan (with $1 million of that being
forgivable principal) with 0.4 percent interest for the
project, which has thinned or harvested nearly 5,000
acres.

MEASURABLE BENEFITS TOOL

Using Flagstaff, Arizona's lessons learned and

comprehensive wildfire impacts and cost avoidance
research, WIFA created a Measurable Benefits Tool
that estimates the environmental, financial, and
social benefits associated with undertaking forest
thinning projects. The tool uses specific metrics such
as cost of wildfire suppression and rehabilitation,
impacts on property values, lost recreational value
and economic activity, job losses, impacts to drinking
water treatment costs, impacts to public health, and
local economic prosperity.

The triple-bottom line tool developed for WIFA could
be adapted to other states. The Measurable Benefits
Tool is customizable by city, county, or national forest.
This allows WIFA to create targeted marketing and
education packages customized by the location and
characteristics of the community and stakeholders.
Targeted marketing provides local residents with a
picture of the potential impact that wildfire can have
on their wallets, health, and community.

The CWSRF can be a key partner in funding various
source water protection efforts, including forest
thinning and fire prevention. In many cases, DWSRF
financing may also be leveraged for this purpose. The
SRFs can be an important part of a comprehensive
strategy to improve forest managment programs
across the western United States.

PENNSYLVANIA WORKS WITH PUBLIC AND
PRIVATE PARTNERS TO PROTECT SOURCE
WATERS

Pennsylvania's CWSRF program, administered by the
Pennsylvania Infrastructure Investment Authority
(PENNVEST), has financed projects that address the
protection of source water from both nonpoint and
point sources of pollution.

LOAN FOR WORKING FOREST
CONSERVATION EASEMENT AND
SUSTAINABLE LAND MANAGEMENT

Promoting responsible land use upstream can
improve downstream water quality. Responsibly
managed forested ecosystems provide a source of
high-quality fresh water at a fraction of the cost
of constructed water treatment systems. Studies
have found that for every 10 percent increase in
forest cover in the source area, drinking water
utility treatment and chemical costs decreased
approximately 20 percent. An agreement between the
Lyme Timber Company LP (Lyme), the Pennsylvania
Department of Conservation and Natural Resources
(DCNR), the Conservation Fund, and PENNVEST will
ensure that 63,500 acres of Pennsylvania forestland
are sustainably managed, providing not only water
quality benefits, but also recreation opportunities,
wildlife habitat, and raw materials for the
Commonwealth's forest products industry.

Lyme, a timberland investment management
organization, specializes in the negotiation of
working forest conservation easements that
restrict development on lands. Once the land is
acquired, Lyme generates income from sustainable
timber harvesting while simultaneously applying
conservation strategies to the land. To secure the
financing for the acquisition of two separate tracts of
land in northwest Pennsylvania, Lyme applied for a
CWSRF loan from PENNVEST.

As part of Lyme's low-interest loan agreement, they:

•	Donated a conservation easement for public
recreational access and water quality protection
on 9,400 acres of timberland in northwest
Pennsylvania,

•	Agreed to perform $750,000 of acid mine drainage
remediation on lands impacted by contamination,
and

•	Agreed to manage an additional 51,000 acres
of land for a seven-year period, subject to
conservation restrictions, while granting rights
to Pennsylvania for the purchase of conservation
easements to permanently protect the land.

PENNVEST provided a $50 million CWSRF loan at an
interest rate of one percent for the project, which will

EPA 832F21025 July 2021

produce savings for Lyme of approximately $900,000
per year during the first five years of the loan (relative
to Lyme's usual 3.5 percent net borrowing cost). The
Conservation Fund (TCF), a non-profit organization
with a dual mission to support conservation and
economic development, supported Lyme's application
and participated in meetings with DCNR. TCF has
agreed to facilitate Lyme's conveyance of conservation
easements on the timberlands, by sale and donation,
to Pennsylvania. The Pennsylvania DCNR will enforce
the terms of the easement.

This project area overlaps with surface water
protection areas that provide water to drinking water
systems serving more than 12,500 homes and to
greater than 700 private wells in areas subject to
conservation easements.

PENNSYLVANIA PROJECT PROTECTS
DRINKING WATER SOURCE FOR 1.5 MILLION
RESIDENTS

Pennsylvania also protects and improves the quality
of source waters by upgrading aging wastewater
infrastructure. The Commonwealth's largest CWSRF
project undertaken to date is improving the drinking
water source of 1.5 million people. The project is a
complete upgrade of the sludge handling facility for
the City of Reading's wastewater treatment plant.
The project addresses the aging infrastructure at
the Fritz Island Treatment Plant that has resulted
in compliance issues and sanitary sewer overflows
during wet weather events.

By addressing the overflows and upgrading the
treatment facility, the water quality for the Schuylkill
River and the Delaware Estuary will improve.
Additionally, the improved water quality will benefit
downstream water supply intakes. The Schuylkill
River is the primary source of drinking water for
approximately 1.5 million people living downstream
from the treatment plant's discharge.

PENNVEST financed this CWSRF project for $149
million at one percent interest for 20 years, which
produced a savings of more than $21 million for the
community.
