Opportunity Information: Apply for EPA OW OGWDW 25 01
The Midsize and Large Drinking Water System Infrastructure Resilience and Sustainability Program is a discretionary grant opportunity from the U.S. Environmental Protection Agency (EPA), authorized under Section 1459F of the Safe Drinking Water Act (SDWA). Its purpose is to help strengthen the ability of medium and large public drinking water systems to keep delivering safe, reliable water when facing growing risks like natural hazards, extreme weather, and cybersecurity threats. In practical terms, the program is aimed at reducing the chances that storms, floods, wildfires, drought, or other disruptive events will damage source water, interrupt treatment and distribution operations, or compromise critical system functions. It also explicitly supports work that lowers exposure to cyber incidents that could disrupt operations, compromise monitoring and control systems, or affect service continuity.
Eligibility centers on public water systems that serve 10,000 people or more. The opportunity materials emphasize that applicants should consult Section 2 of the Notice of Funding Opportunity (NOFO) for the full eligibility rules and any additional conditions or definitions that apply. The eligible applicant category is listed as "Others," which commonly signals that the specific eligible entities are defined within the NOFO rather than being limited to a narrow government-only category, but the core qualifying requirement described is that the applicant is a public water system meeting the minimum population threshold.
Fundable projects are those designed to increase resilience to natural hazards and extreme weather events and/or reduce cybersecurity threats. That can include efforts that protect drinking water sources and the infrastructure that supports treatment, storage, and distribution, as well as planning and implementation activities that harden systems against future disruptions. The program focus is on tangible improvements to system robustness and continuity of operations, whether that is through physical upgrades, operational improvements, risk reduction measures, or cybersecurity-oriented investments that better secure and maintain critical services.
From an administrative standpoint, the opportunity is issued by the EPA under Funding Opportunity Number EPA OW OGWDW 25 01, within the environmental funding activity category. The assistance listing is CFDA 66.488, and awards are made as grants. The expected number of awards is six, with an award ceiling of $9,500,000 per award, indicating the program is geared toward larger-scale projects and major resilience investments that can have substantial system-wide impact. The original application closing date is October 6, 2025, and the opportunity was created on August 5, 2025. Additional program details, guidance, and updates are available through EPA's program webpage at https://www.epa.gov/dwcapacity/midsize-and-large-drinking-water-system-infrastructure-resilience-and-sustainability, alongside the NOFO, which is the controlling document for requirements, evaluation criteria, and the full list of allowable activities.Apply for EPA OW OGWDW 25 01
