Public Wastewater System Planning Grants

DEQ's Wastewater Planning Grant Program provides financial assistance to eligible entities in Idaho planning to upgrade public wastewater facilities. Each prospective project is assigned a priority rating, with the highest rankings given to projects that will most significantly improve the quality of the waters of the state and protect public health. Grants awarded under this program must be used entirely to prepare facility plans that identify the most cost-effective, environmentally sound methods to upgrade public wastewater systems to achieve and maintain compliance with state and federal standards. Grants cover up to 50% of eligible planning costs, with the grantee providing a matching share from local sources.

Program Eligibility

Wastewater planning grants are available for counties, cities, special service districts, other governmental entities, nonprofit corporations, and combinations thereof that have authority to collect, treat, or dispose of wastewater. Most systems owned by Idaho municipalities, special service districts, and associations are eligible for grants.

Grant Process

Once each year, DEQ contacts eligible systems to solicit interest in applying for a planning grant. Those who are interested in applying for a planning grant must submit a Letter of Interest (LOI) to DEQ. Responses, submitted as a LOI, are evaluated, rated, and ranked by DEQ for inclusion on the next annual priority list. Rating criteria focus on potential public health risks, long-term viability of the system (i.e., sustainability), and the status of the system’s compliance with state and federal regulations. The highest rankings are given to projects that DEQ has determined will most improve the waters of the state, provide for system sustainability, and best protect public health.

The highest rated projects for which funding exists will be invited to submit a planning grant application. The number of grants offered each year is limited to available funding. Systems selected to receive grants are required to hire a professional engineer to survey the existing condition of the system, develop and screen alternatives to enable the system to meet future needs, select a recommended alternative, and evaluate the potential environmental impacts. An environmental information document is required of all grant recipients, and a system may be required to develop and implement mitigation measures as the project moves into design and construction.

Each year DEQ prepares a priority list defining how it intends to allocate resources for wastewater facilities planning. The fiscal year (FY) 2018 priority list was reviewed and adopted by the Board of Environmental Quality in May 2017. The fiscal year (FY) 2019 priority list was reviewed and adopted by the Board of Environmental Quality in May 2018.

FY 2019 Grant Recipients

  • City of Preston, Franklin County ($65,000): Funds will be used to prepare a wastewater planning study and environmental review. The purpose of the project is to evaluate the current wastewater system and identify any needed improvements.
