State Revolving Funds (SRFs) provide critical support for a variety of water and wastewater projects, including drinking water and wastewater treatment facilities and stormwater pollution management.NRDC | Image: Canva
Benefits: “SRFs involve federal, state, and local partnerships, thereby helping to support local economies. Every dollar invested in water infrastructure generates roughly $2.62 in the private economy, and every new job added in the water sector adds 3.68 jobs to the national economy due to the benefits of clean water.”
History: “The Clean Water State Revolving Fund (CWSRF) was created in 1987 and its success spurred the subsequent creation of the Drinking Water State Revolving Fund (DWSRF) in 1996.”
- CWSRFs fund projects for water quality protection projects (e.g., nonpoint source pollution, watershed protection, municipal wastewater treatment).
- DWSRFs fund projects for drinking water projects (e.g., source water, treatment, transmission and delivery).
How it works: “Both the CWSRF and the DWSRF are administered by the states, but they are subject to oversight and programmatic regulations and guidance issued by the EPA. Each state is provided with a proportionate share of the annual Congressional appropriation (which is augmented by a required state match amount) to capitalize these revolving loan funds. States provide loans to communities from these funds, and the loan repayments are returned to the funds.”
