Hauled Recycled Water

NapaSan produces high quality recycled water that can be safely used for irrigation.  For customers not connected to a recycled water pipeline, it's possible for recycled water to be hauled to a property by truck.  

Customers can either haul the water themselves or hire a company to haul the recycled water to their property: NapaSan does not provide recycled water delivery by truck.  

Recycled water production and use is regulated by the state of California.  NapaSan is the local agency responsible for issuing permits for all recycled water uses in its sphere of influence, including truck hauling.  

Requirements for Hauling Recycled Water

Four essential program requirements must be met prior to the commencement of hauling recycled water.  

1. An agreement must be entered into between the recycled water user and NapaSan which sets forth the reuse program authority and contractually binds the user to abide by the reuse program rules.  

2. Each truck or tank that will be used to transport recycled water must be labeled to notify the public, users, and workers, that recycled water is being hauled in the tank, and that it is not fit for human consumption.  Inspection by NapaSan staff will verify that this requirement has been met. 

3. Training by NapaSan will be provided to the truck driver regarding the procedures to follow when filling the truck tank under normal conditions, and what to do in case of an emergency.  

4. NapaSan will issue a truck hauling permit to the user, which must be carried in the truck at all times.  An annual fee of $50 is required at the time of permit issuance.  

Storage and Distribution

If the recycled water will be stored onsite in a pond or tank, these facilities must be inspected by NapaSan staff.  In addition, before distributing the water through a fixed irrigation system, a cross connection assessment must be made.  Each agricultural operation is unique; NapaSan will provide the guidance necessary for the successful use of recycled water on your property.  


Two recycled water fill stations are available for customer use.  The first station is located at NapaSan's facility at 1515 Soscol Ferry Road, Napa. The other station is located on Coombsville Road just east of Silverado Middle School.  These stations are accessible Monday through Friday from 7:00am to 5:00pm.
