South County Regional Wastewater Authority - Gilroy, CA - Wastewater Treatment Facilities on Waymarking.com

The South County Regional Wastewater Authority (SCRWA), located at 1500 Southside Drive in Gilroy, California, is a joint powers authority formed to manage wastewater treatment and water reclamation services for the cities of Gilroy and Morgan Hill. Established in 1990, the facility has been recognized for its energy-efficient and cost-effective operations.


To accommodate regional growth and enhance treatment capabilities, SCRWA is undertaking a significant expansion of its wastewater treatment plant. The project includes the addition of a 2.5 million gallons per day (MGD) membrane bioreactor (MBR) facility, increasing the plant's capacity from 8.5 MGD to 11 MGD. This expansion aims to provide higher-quality effluent suitable for various uses, including industrial applications and municipal irrigation.

SCRWA also operates a recycled water facility, initially commissioned in 1995 with a capacity of 3 MGD and expanded in 2006 to 9 MGD. The facility supplies recycled water for non-potable uses such as irrigating parks, golf courses, and agricultural lands.

The SCRWA facility is regulated under the National Pollutant Discharge Elimination System (NPDES) Permit No. CA0049964, ensuring compliance with environmental standards for wastewater discharge and treatment.

What is the capacity of the facility?: 11 MGD Describe the biological treatment technology used.: To enhance treatment efficiency and meet increasing demand, SCRWA is expanding its facility to incorporate Membrane Bioreactor (MBR) technology. MBRs combine biological treatment with membrane filtration, allowing for higher-quality effluent and greater treatment capacity. The MBR system includes new headworks, bioreactors, membrane basins, blowers, chemical feed and storage facilities, and solids handling units. How are biosolids (sludge) managed?: Initially, solids are separated from the wastewater through primary and secondary treatment processes. These solids are then thickened and stabilized to reduce pathogens and odors, preparing them for further processing. What technology is used for disinfection prior to dicharge of treated water?: The South County Regional Wastewater Authority (SCRWA) in Gilroy, California, employs ultraviolet (UV) light disinfection as its primary method for treating wastewater before discharge. This transition from chlorine-based disinfection to UV technology was Who is the owner/operator fo the facility?: South County Regional Wastewater Authority How is the facility governed?: Not listed What is the website of the WWTP?: Not listed
