At NapaSan, our goal is to protect public health and the environment by collecting and treating wastewater, producing high quality recycled water, and promoting pollution prevention. But we can’t do it alone.

We depend on our customers to be our partners in pollution prevention, because what goes down the drain is just as important as how the wastewater is treated at the other end. By taking care with the products you use and how you dispose of them, you can help protect your plumbing, community health, and the environment.
