Project Description: Reclamation plant of West Basin Municipal Water District, plant arid appurtenant facilities built on 24 acre site in El Segundo, CA. West Basin Municipal Water District barrier RO system 2.5 MGD expansion.

The project consisted of a complete mechanical package including equipment, process piping, plumbing and HVAC. At the time it also included the largest RO facility West of the Mississippi River. Murray Company took effluent from Hyperion WWTP through a 60″ line and further cleaned it to make Title 22 grey water for irrigation as well as RO water for regeneration of the underground salt water barrier in the South Bay.

The project was fast track and presented coordination issues for large diameter pipe fabrication and equipment deliveries. Much of the piping for the facility is very large bore and underground. A trench 16′ deep and 54′ across ran down the center of the facility and contained three layers of various pipes ranging in size from 60″ down to 8″. There were so many excavations for the piping that it made site access very difficult.
