Background
The purpose of the Clean Water Act Indian Set-Aside (CWISA) Program is to provide
funding for wastewater infrastructure to federally recognized tribal governments and
Alaska Native Villages. Funds may be used for planning, design and construction
of wastewater collection and treatment systems. The CWISA Program is adminis-
tered by the Environmental Protection Agency (EPA) in cooperation with the Indian
Health Service (IHS). The program was established by the 1987 Amendments to the
Clean Water Act, in Section 518(c).
How to Apply
To apply for funding from the CWISA Program, tribes must first contact their IHS
Area Office (www.ihs.gov/dsfc/stafi) to determine if their wastewater needs are eligi-
ble to be entered into the IHS Sanitation Deficiency System (SDS) list. EPA provides
funding for wastewater projects that are ranked and listed on the SDS list.
How the Program Works
The SDS identifies current sanitation deficiencies for existing tribal homes; projects for future needs will not be
considered. EPA uses the SDS list to identify priority wastewater projects for funding. CWISA Program Coor-
dinators in each EPA Region and IHS Area work together to determine the projects to be funded based on the
ranking of projects in the SDS and available CWISA funding. Projects are ranked in the SDS based on eight fac-
tors: health impact, existing deficiency level, previous service, capital cost, operation and maintenance capability,
contributions, local tribal priority, and local conditions. For example, projects that would resolve public health
concerns would rank higher than projects designed to rectify water quality problems.
Annual Funding Levels
EPA Region 9 receives approximately $10 million and funds more than 30 wastewater projects each year.
*	The average award amount for individual projects is $300,000. In recent years, award amounts have ranged
from less than $20,000 to over $1 million. Award amounts will vary depending on the type of project.
*	No matching funds are required.
Tentative Schedule
Year 1:
January - May Tribes identify sanitation needs to IHS Area Offices
June Deadline for submission of tribal needs to IHS Area Offices
June - July IHS Area Offices review and rank projects submitted to the Sanitary
Deficiency System (SDS)
August - October IHS Headquarters reviews IHS Area Offices SDS project submissions
November Final SDS lists made available to EPA CWISA Program Coordinators
Year 2:

April - September EPA Regional CWISA Program Coordinators notify tribes that have been
selected for funding and award CWISA Program funds
The CWISA Program addresses
wastewater deficiencies such as
this failed septic system.

•	Project planning, design, and Preliminary Engineering Report (PER)
•	Infrastructure construction and major sewer rehabilitation
•	Wastewater treatment facilities (conventional or alternative)
•	Correction of combined sewer overflows
•	Collector sewer pipelines
•	On-site wastewater treatment systems (e.g., septic systems)
•	Follow-up and as-built drawings of funded wastewater projects
•	Operator training on new infrastructure equipment for first year
Eligible Projects
All projects funded by the CWISA Program must support wastewater-related activities or projects. CWISA
Program funds cannot be used to pay for the cost of operation and maintenance of the wastewater facility nor
can they be used to pay for repairs to the treatment system in emergency situations. Project components eligible
for funding include:
Ribbon-cutting ceremony for the sewer main
replacement project
Project: Sewer Main Replacement -
San Carlos Apache Tribe
EPAs CWISA Program collaborated with IHS and the tribe to fund and
construct the Sewer Main Replacement Project to replace failing 6-inch-
diameter clay sewer mains in one area of the reservation in San Carlos,
Arizona. Hie IHS contributed $700,000 for the project and provided techni-
cal assistance to the tribe with engineering and project technical support
services. EPA contributed $590,000 of CWISA Program funds. In total,
the project installed approximately 7,000 linear feet of 12-inch and 8-inch-
diameter sewer mains, approximately 60 service connections, and 22 precast
concrete manholes. Approximately 1,000 tribal members will benefit from
constru ction of these new sanitation facilities, which were primarily con-
structed by the San Carlos Apache Tribe. The project management team
succeeded in planning and organizing large, complex, multifunction efforts,
including managing existing utility conflicts and coordinating with existing
homeowners in residential areas. Hie project culminated with a ribbon
cutting ceremony on December 21, 2017.
