What it does
This bill amends the Federal Water Pollution Control Act to require states receiving federal water infrastructure grants to spend at least 20% of those funds on green infrastructure, water efficiency, energy efficiency, or other environmentally innovative projects. The requirement applies to all future appropriations and is conditioned on the availability of eligible project applications.
Why we flagged it
The bill's operative mechanism is a straightforward spending mandate: states must allocate a minimum percentage of federal water grants to green and efficiency projects. This is a direct environmental policy tool, not a tax provision, subsidy, or deregulation.
What the text implies
- The 20% floor may reduce funding available for traditional water treatment and conveyance projects in states with high conventional infrastructure needs, potentially creating tension between environmental goals and immediate water-safety upgrades.
- The 'sufficient eligible project applications' condition gives states discretion to claim insufficient green projects exist, potentially allowing circumvention of the mandate if state environmental planning lags.
- Capitalization grants fund state revolving loan funds (SRFs), which then lend to municipalities; the mandate flows through to local water systems, shifting environmental compliance costs to ratepayers unless federal funding fully covers the green projects.

Who it affects
Ordinary citizens benefit from mandated investment in green infrastructure, water efficiency, and energy efficiency projects, which typically reduce long-term water costs, improve environmental quality, and enhance resilience. The 20% floor ensures environmental priorities are not crowded out by conventional infrastructure spending.
Who stands to gain
- green infrastructure contractors and consultants
- water efficiency technology vendors
- renewable energy and efficiency equipment manufacturers
