Water Infrastructure Resilience and Sustainability Act of 2026

Bill Summary: Water Infrastructure Resilience and Sustainability Act of 2026

Overview

The Water Infrastructure Resilience and Sustainability Act of 2026 (S. 3590) is a targeted legislative action designed to ensure the continuity of federal funding and support for critical water infrastructure projects across the United States. The primary intent of the bill is to extend the authorization of existing resiliency and sustainability programs for both clean water and drinking water systems.

Key Provisions

The bill focuses on the reauthorization of three specific programs by extending their legal authority from the previous cycle (fiscal years 2022–2026) to a new five-year window (fiscal years 2027 through 2031).

1. Clean Water Infrastructure

• Program: Clean Water Infrastructure Resiliency and Sustainability Program.
• Action: Amends the Federal Water Pollution Control Act to extend the program's authorization through 2031.

2. General Drinking Water Infrastructure

• Program: Drinking Water Infrastructure Resilience and Sustainability.
• Action: Amends the Safe Drinking Water Act to extend authorization for general resilience and sustainability efforts through 2031.

3. Midsize and Large Drinking Water Systems

• Program: Midsize and Large Drinking Water System Infrastructure Resilience and Sustainability Program.
• Action: Amends the Safe Drinking Water Act specifically to maintain support for larger-scale water systems through 2031.

Who is Affected?

This legislation primarily impacts:
* Municipalities and Local Governments: Those managing wastewater and drinking water utilities who rely on federal grants or loans for infrastructure upgrades.
* Water Utility Providers: Specifically those operating midsize and large-scale drinking water systems.
* The General Public: By ensuring that funds remain available to modernize water infrastructure, the bill aims to maintain long-term water quality and system reliability.

Procedural Status and Timeline

• Introduced: January 7, 2026, in the Senate.
• Current Status: The bill has been read twice and referred to the Committee on Environment and Public Works.
• Effective Period: If passed, the reauthorizations will govern the fiscal years 2027 through 2031.

Impact Analysis

This is a "maintenance" bill. It does not create new programs or change existing regulations; rather, it prevents critical funding streams from expiring. By extending these authorizations, the bill provides stability for long-term infrastructure planning and ensures that federal resources remain available to protect the nation's water systems against climate-related threats and aging infrastructure failures.
