Bayou City Waterkeeper (Houston, Texas). Bayou City Waterkeeper is a 25-year-old nonprofit protecting Houston’s waters and communities through bold legal action, community science, and grassroots policy advocacy. Their work has delivered major wins for Houston-area communities, including a 2021 consent decree driving billions of dollars of investment into long-neglected sewage infrastructure, helping advance equity in flood infrastructure spending following Hurricane Harvey, and helping pass Proposition 4 — a Texas constitutional amendment unlocking $20 billion in statewide water infrastructure investment. BCWK centers the communities most impacted by water pollution, flooding, and infrastructure failures through innovative tools like Water Justice Zones, the Community Research Action Network, and a newly launched Green Infrastructure Design Lab in Northeast Houston that equips residents to design community-driven solutions.
