Protecting public health and the environment is what the Fresno/Clovis Regional Water Reclamation Facility is all about. If you don't already know us, let's get acquainted! The Fresno/Clovis Regional Water Reclamation Facility is operated by the City of Fresno and provides wastewater treatment services for the greater Fresno metropolitan area.
On an average day, the Regional Wastewater Treatment Plant in Fresno, California, receives 68 million gallons of wastewater - enough to cover a football field to a height of more than 15 stories. If you live in Fresno, Clovis or some areas of Fresno County, you produce part of that wastewater.
The average American produces about 183 gallons of wastewater every day from toilets, showers, washing machines and many other domestic sources. And that's not counting the millions of gallons of wastewater produced by businesses and industries throughout the Fresno metropolitan area.
The Fresno-Clovis Regional Wastewater Treatment Facility is located at Jensen and Cornelia in southwest Fresno. Wastewater generated from homes and businesses in the metro area travels through 1700 miles of sanitary sewer lines to the Wastewater Treatment Facility. Treatment consists of two major steps; primary and secondary treatment, and a process to treat solids removed in the process at the plant.
Primary treatment of wastewater physically removes sand, grit, and the larger solids in the wastewater using screens, settling tanks, and skimming devices. Secondary treatment removes contaminants dissolved in the wastewater through biological processes aided by air to encourage bacteria growth. Solids (bio-solids) removed from the processes are treated anaerobically in digesters and dewatered through mechanical filter presses.
Treated or reclaimed wastewater is directed to 1660 acres of ponds to percolate into the ground. A portion of the reclaimed wastewater is also supplied directly to nearby farmers to irrigate fodder and fiber crops, such as alfalfa and cotton.
Bio-solids are picked up daily by a composting company which further treats and mixes them with other materials, making a product that is sold in the market as fertilizer.
The Fresno-Clovis Regional Wastewater Treatment Facility has capacity to treat 80 million gallons a day (mgd) of wastewater. Toxic materials and even too much water can hamper the treatment of wastewater. Minimizing harmful chemicals helps keep our biological process healthy, allowing us to adequately clean the water. Limiting the use of water allows us to continue to use present facilities and delays the need to further expand our facility, keeping sewer rates low for the community.
