PROJECT HIGHLIGHTS
Ovivo's Enviroquip MBR is part of Tejon Ranch's ongoing efforts for enviromental sustainability.
DESCRIPTION
At nearly 270,000 acres, Tejon Ranch is the largest continuous expanse of private land in California. Its 422 square miles make it almost as large as the City of Los Angeles. To support the expansion of the Tejon Industrial Complex, Tejon Ranch Company (TRC) decided to upgrade their treatment system with Ovivo’s Enviroquip MBR because it was the most simple, reliable, cost competitive system that could meet and exceed their reuse requirements. The system was designed to grow with the Tejon Industrial Complex at 100,000 gpd increments, handling 3 times the normal municipal loading. TRC reuses the water to irrigate landscape and other vegetation areas. California Water Services Company operates the system with 2 maintenance cleans a year or less.
