Wastewater Treatment

The City owns and operates the existing wastewater treatment plant (WWTP) under California Regional Water Quality Control Board (CRWQCB) Waste Discharge Requirements (WDR) Order No. 94-184. The purpose of the Plant is to collect and treat municipal sewage to such a degree that its discharge will not endanger public health nor degrade groundwater quality.

Proposed New Wastewater Treatment Facility

The City of Coalinga is undertaking the construction of a new wastewater treatment and sewer trunk line as well as decommissioning of the existing wastewater facility in order to provide additional capacity to support growth in the area and allow development within the parameters identified in the City’s General Plan.  The City intends to use proven technology to treat wastewater for beneficial reuse.  The site proposed for the new wastewater treatment plant (WWTP) is located southwest of the intersection of Jayne Avenue (Highway 33) and Alpine Avenue (Highway 33), outside the current city limits of the City of Coalinga.  The property is approximately 477 acres, encompassing Assessor Parcel Nos. 085-02-036, 085-02-037, and 085-02-029. Jacalitos Creek crosses the northwest corner of the property.

The City of Coalinga is proceeding with the new wastewater treatment facility and sewer truckline under the design build process. For more information regarding the design build precurement process and the new wastewater treatment facility, please go to the Design Build Project Website.
