Drinking Water State Revolving Fund (DWSRF)

General Information

The Drinking Water State Revolving Fund (DWSRF) makes funds available to drinking water systems to pay for infrastructure improvements. This program is funded through federal and state money and subject to state laws and additional federal regulations.

The program provides:

  • Low-interest construction loans to publicly (municipal) and privately owned drinking water systems. These loans cover capital improvements that increase public health and compliance with drinking water regulations.
  • Construction loan repayments can range from 20 to 30 years. In some cases, partial loan forgiveness is offered.
  • Planning and engineering loans to cover preconstruction work and activities such as water system plans, engineering designs, and cultural reviews.
  • Consolidation Feasibility Study grants allow larger Group A community water systems such as cities, town, counties, public utility districts, and water districts to determine feasibility and capital improvements needed to consolidate smaller or struggling water systems into their service area.

There are many federal requirements for loans and grants from DWSRF. Requirements include completion of cultural and environmental reviews, SEPA, Davis Bacon Act, Build America Buy America, loan management, construction management, and others.

Emergency Loan Program

Group A not-for-profit water systems serving fewer than 10,000 people can apply for a loan of up to $500,000 to cover emergency recovery activities.
DWSRF program guidelines allow states to use funds from this program for recovery activities related to emergencies, such as drought and wildfires. This loan program will ensure we are ready and able to award loans to water systems that may be in violation of health and safety standards due to an emergency.

Systems can use the funds for construction, reconstruction, replacement, rehabilitation, temporary repair, generator or treatment equipment rentals, or improvement needed to continue or restore drinking water service.

Read the DWSRF Emergency Guidelines 331-545 (PDF) to understand the requirements for this program and gather necessary documentation.

When ready, you can apply using the DWSRF Emergency Loan Application Form 331-542-F (Word).
