U.S. Environmental Protection Agency (EPA) Region 9 provides annual funding opportunities for federally
recognized tribal governments to support drinking water infrastructure and basic sanitation needs. Outlined
below is information about our water infrastructure programs, eligibility and funding. All selection criteria
include public health as a high priority.
Drinking Water Tribal Set-Aside Program
The Drinking Water Tribal Set-Aside Program (DWTSA) provides annual
funding for federally recognized tribes for public drinking water systems.
DWTSA funds come from a 2% set-aside of the Safe Drinking Water Act
State Revolving Loan Fund (SRF) program. EPA's 2022 request for propos-
als is available at www.epa.gov/tribal/region-9-drinking-water-tribal-
set-aside-program. The current solicitation closes on November 19, 2021.
The highest priority projects are selected for funding based on public health
ranking criteria. Funds are awarded through direct grants to federally rec-
ognized tribes or via interagency agreements with the U.S. Indian Health Service (IHS). Funding levels have
ranged between $40,000 and $2 million per project. In FY21, EPA Region 9 funded approximately $8 million in
drinking water infrastructure projects.
Clean Water Indian Set-Aside Program
The Clean Water Indian Set-Aside Program (CWISA) provides annual
funding for federally recognized tribes for planning, design and construc-
tion of wastewater infrastructure projects. CWISA funds come from a 2%
set-aside of the Clean Water State Revolving Loan Fund (SRF).
To apply for funding, tribes must first contact their IHS Area Office
(www.ihs.gov/dsfc/staff) to determine if their wastewater needs are eligible to be entered into the IHS Sanita-
tion Deficiency System (SDS) list, which identifies current sanitation deficiencies for existing tribal homes. The
program is not competitive, and matching funds are not required. The funds are awarded annually, based on the
wastewater project needs listed on the SDS list, through interagency agreements with the IHS or direct grants to
federally recognized tribes. Average funding levels have been approximately $300,000 per project.
Project: Backup Power Generators for Tribal Water and
Wastewater Systems - Tribes Throughout California
Due to extreme wildfire events, commercial power providers in California expanded a Public Safety Power
Shutoff (PSPS) Program. This resulted in unpredictable and extended loss of power for tribes, some outages
lasting more than five days. Consequently, many tribal water and wastewater systems have been at a high risk
of water outages or sewage overflows because there was no backup power or sufficient storage. The partnership
between EPA, and the California Office of Emergency Services has made this tribal program a success. All three
partners have been critical to identifying needs, funding projects, doing outreach to tribes, and taking the lead
on planning, design and installation of these generators.

In 2019 and 2020, EPA awarded $1.66 million in DWTSA and CWISA
funding to assist 23 tribal water and wastewater systems. An additional $1.2
million in IHS and State of California funds have been committed to assist
16 water and wastewater systems with backup power generators. A total of 24
backup power generators have been installed to date through this partnership,
with many others in the design, solicitation or construction stage. Several of
these generators have already been used to keep water and wastewater
systems functioning during power outages in 2021, including a September
power outage affecting the Tsenungwe Tribe caused by a nearby wildfire.
Completed DWTSA Project: Flow Meter Installation
and Vault Upgrades for Arsenic Compliance
The Los Coyotes Band of Cahuilla and Cupeno Indians (Band) water system
improvement project was awarded $258,000 through the DWTSA Program to
address multiple deficiencies including isolation from the failing older water
main, and failures and safety issues experienced by the existing pressure
reducing stations. There are 21 homes and several tribal facilities connected
to the water system. This project replaced two below ground pressure reduc-
ing stations that experienced severe corrosion and flooding with above-ground
facilities. In addition, the project isolated and abandoned all connections
between the older and newer water systems and installed chain link fencing
around the water storage tank. The project was completed in February 2021 in
IHS and the EPA.
