Welcome to the North Bay Water Reuse Program website. The NBWRP is a regional water recycling initiative encompassing over 350 square-miles in portions of Marin, Sonoma, and Napa counties surrounding northern San Francisco Bay, known as San Pablo Bay. The Program is a coordinated effort of 11 municipal, water, and wastewater agencies working collaboratively to develop water resiliency in the broader region.

In 2002, NBWRA agencies undertook the cooperative, watershed-based, regional planning effort that initiated the North Bay Water Reuse Program (NBWRP).
