DSRSD Tap Water is Safe, Reliable, and Available

DSRSD is committed to providing its customers with safe and reliable water that is both available and plentiful.

DSRSD receives drinking water from Zone 7 Water Agency, the Tri-Valley’s water wholesaler. Zone 7 disinfects and removes pollutants from surface water using a multi-barrier approach, and groundwater is disinfected with chloramine (chlorine and ammonia). After receiving treated water, DSRSD maintains a consistent residual level of disinfectant in its distribution system and flushes pipelines to prevent bacterial growth.

DSRSD potable (drinking) water meets or exceeds all stringent state and federal drinking water requirements. DSRSD’s most recent Annual Water Quality Report is available on our website. 

Recycled water used for irrigation is also disinfected with methods that should deactivate COVID-19. Following pretreatment, primary, and secondary treatment, cleaned wastewater is then disinfected with sodium hypochlorite (bleach). The chlorine contact provides proper levels of disinfection. For recycled water, after undergoing tertiary filtration, the recycled water is then exposed to UV (ultraviolet) light disinfection, which kills or inactivates any bacteria or viruses that might remain in the water. UV light destroys the DNA of pathogens.
