CONSTRUCTION MANAGEMENT:

Solving problems before they’re problems.

Engineering is a science, requiring creative thinking. Construction is an art, requiring precise execution. We bring both to the build site, for results far greater than the sum of their parts. With our construction managers’ leadership, water engineering expertise and technical support, we’re able to reduce risk, enhance communication, streamline processes and optimize the quality, compliance and sustainability of every facility. It’s one more way we’re helping California build better water infrastructures for a better quality of life.

Construction Management Services for the Torrance and Dominguez Booster Pump Stations and Carson Mall Lateral, West Basin Municipal Water District

LEE + RO provided construction management and inspection services during construction for the Torrance Booster Pump Station, Dominguez Booster Pump Station, and Carson Mall Recycled Water Lateral projects. These projects were part of the Harbor South Bay Project, a partnership program between West Basin and the U. S. Army Corps of Engineers, for providing Title 22 recycled water to the South Bay Area irrigation and industrial customers.

The Torrance Booster Pump Station, located within the property of West Torrance High School in the City of Torrance, boosts pressure in the recycled water system off of the Anza Avenue Recycled Water Lateral. There are three main pumps and two jockey pumps that deliver from 50 gpm to 750 gpm flow range in the recycled water distribution system. The pump station equipment is housed in a reinforced masonry structure. Dominguez Booster Pump Station, located in a private lot, includes two main pumps and one jockey pump, a sodium hypochlorite disinfection system and related equipment, all housed in a CMU building. The pump station boosts recycled water pressures for the customers located in the City of Carson. The Carson Mall Lateral project includes about 4,000 lineal feet of 12-inch diameter recycled water lateral from the existing 42-inch diameter recycled water main at Broadway and Main Street in Carson to the proposed Carson Mall development. A portion of the pipeline is hung from a bridge. The construction management and inspection services provided followed rigorous Army Corps of Engineers requirements. The construction management services included specialty inspections and materials testing, community interaction, coordination with the Cities of Torrance and Carson, Southern California Edison, and Torrance Unified School District. Traffic control, noise mitigation, dust suppression and community impacts were of concern for ensuring smooth construction.
