SAN FERNANDO GROUNDWATER BASIN REMEDIATION PROJECT

Los Angeles, California

MEC managed the electrical installation for two new facilities as part of this progressive design-build (PDB) project. The facilities extract water from two sets of existing, non-producing groundwater wells as part of the client’s comprehensive, long-term plan to replenish and store contaminated groundwater at sites across the 175-square-mile San Fernando Groundwater Basin.

To build facilities able to treat 50 and 25 million gallons per day (MGD) respectively, the project entailed 6,500 feet of raw-water pipelines, ultraviolet (UV) buildings and several pumps. The facilities also contain purge systems, pre-treatment separators, 10 UV advanced oxidation process reactors, three liquid-phase granular activated carbon (GAC) systems with 54 new GAC vessels, and post-treatment systems providing chlorination, ammonization and fluoridation.

MEC’s scope included two 5,000-amp main switchboards, 700,000 linear feet of wire and 2,300 UV lamps among six UV reactors centrally located in the UV building.
