Providing sewer service to local businesses is an important part of Napa Sanitation District’s mission. Businesses have special needs for protecting their sewer lines and managing potential pollutants in their wastewater stream. In this section you can find out how to connect to the sewer system, and also find resources for pollution reduction and prevention specific to the type of business you operate.

In this section you can also find information if you are a business interested in providing goods or services to the District.

For sewer problems, CALL US FIRST!
Collection System Department
707-258-6000 ext 9
Day, night, weekends or whenever, if you’ve got a problem with your drains, just call us first. If the problem is in our sewage mains or laterals, we can save you the cost of a plumbers visit. Our answering service will take your name, address and telephone number, and a member of our crew will call you back or be on your doorstep within 30 minutes.

This service is free of charge. Keep in mind that the sewer lateral from the property line to the building is the responsibility of the property owner. If the problem turns out to be in your section of the sewer line, you may still need a plumber’s help.
