Tetra Tech is a global leader in the science, engineering, and construction of water and wastewater solutions. Our specialists combine their expertise in the design and operation of biological and physical/chemical processes to meet our clients’ need for effective and efficient treatment facilities. 

The current drought in California has created a huge demand for recycled water. Tetra Tech is working with our long term client, the Irvine Ranch Water District, to expand the Michelson Water Treatment Plant. This expansion uses new technologies, such as membrane bioreactors and ultraviolet light disinfection facilities, to increase the plant’s water production from 18 to 28 million gallons per day.
