Water – Wastewater – Storm Drain
The City of Gustine is a full service utility providing water, wastewater and storm drain services to over 5,500 residents. Gustine’s water supply is provided through pumping ground water from an underground aquifer. The City of Gustine water meets state requirements for safe drinking water, more information on this can be found in our Water Quality Report.

The City of Gustine also provides wastewater services, and operates a 12 pond marsh system wastewater treatment facility. The plant commonly processes anywhere from 500,000 to 1,400,000 gallons of wastewater per day.

The City of Gustine’s storm drain system collects storm water and transfers the storm water to the Central California Irrigation District. The Storm drain system prevents localized flooding and allows for safe and orderly traffic patterns to continue unobstructed by rainy weather.
