Protecting the Napa River

Before the Napa Sanitation District began serving the community in 1945, untreated sewage and stormwater drained together to the Napa River. A growing population in Napa increased the pressure on the river, and the pollution from sewage created a health hazard and resulted in fish kills.

Since its founding, protection of the Napa River has been central to the mission of the Napa Sanitation District. Wastewater is treated to secondary standards, making it safe for river discharge during the wet season (November 1 to April 30 annually). During the dry season, wastewater is recycled and used to irrigate landscaping, vineyards, golf courses and pastureland.

In addition to providing high quality wastewater treatment to protect the Napa River, the District also contributes to river protection through the following activities:

Fish Friendly Farming:

This program, administered by the California Land Stewardship Institute evaluates and guides land management practices to protect water quality and fish habitat. The District developed Farm Conservation Plans to allow properties owned by the District to receive Fish Friendly Farming certification in 2013.

Watershed Information and Conservation Council of Napa County:

The District is a member of the Watershed Information and Conservation Council (WICC), which guides and supports community efforts to maintain and improve the health of Napa County’s watershed lands. The Napa Sanitation District maintains a listing on the WICC website to educate the community about education opportunities and resources we provide.

Creek to Bay Clean Up Day:

 The District sponsors and assists with this event, which is organized each year in September by the Napa County Resource Conservation District. In 2010, this even removed over a ton of trash from throughout the Napa River watershed!
