Recycled Water Truck Fill Program


Central San’s Recycled Water Truck Fill Program provides high-quality, tertiary-treated recycled water to licensed contractors for construction uses (e.g., dust control, soil compaction, and plant establishment) in Central San’s service area.

As part of Central San’s ongoing efforts to help conserve drinking water supplies, Central San is offering recycled water to truck-fill customers free of charge, for the first 100,000 gallons per customer per year.

Our Automated Commercial Fill Station — located near our treatment plant on Imhoff Drive in Martinez—offers a quick and easy way to withdraw recycled water.

Or contractors may obtain a portable recycled water meter for use on one of Central San’s three recycled water hydrants. A $1,000 refundable deposit is required to obtain a portable meter. Click on the links below for more information, including an application for service.
