Safe drinking water is a carefully manufactured product. It is collected, treated, tested and delivered to your home and/or business by the City of Manteca.

WaterThe City of Manteca has been delivering water to the public since 1917. During those 90+
years, we have constructed a total of 25 wells for domestic use. The water system currently consists of 18 groundwater wells. Seven wells have been taken out of service due to their old age and shallow depths.

The water that is pumped from the ground is pushed through approximately 170 miles of
pipeline located underneath City streets. We currently receive 100% of our drinking water from groundwater sources, but surface water will be available in the future.
