The San José-Santa Clara Regional Wastewater Facility deemed the largest advanced wastewater treatment on the West Coast, United States, is responsible for cleaning up Silicon Valley's wastewater round the clock while protecting public health and the environment and supporting the economy. The facility has been implementing innovative solutions and advanced technologies as part of its modernization drive to provide clean water and a sustainable future to its residents.
ABB was selected by the wastewater treatment facility to modernize the systems and solutions and implement a solid cyber security infrastructure while optimizing the water purification process.
The Facility, which is jointly owned by the cities of San José and Santa Clara and is managed and operated by the City of San José's Environmental Services Department, treats on an average 110 million gallons of wastewater per day (mgd), with a capacity of up to 167 mgd.
The wastewater first undergoes advanced tertiary treatment that leads to 99 percent purification. After the tertiary treatment, about 80 percent of the treated water is piped to the outfall channel. From here, it flows to Artesian Slough, through Coyote Creek, and eventually into the South San Francisco Bay. The remaining 20 percent of the treated water is sent to South Bay Water Recycling and used to irrigate food crops, parks, schools, golf courses, street medians, and business park landscaping.
