Juanita Millender-McDonald Carson Regional Water Recycling Plant Phase II Expansion

Butier Engineering, Inc. provided construction management services for West Basin Municipal Water District's Juanita Millender-McDonald Carson Regional Water Recycling Plant (JMMCRWRP) Phase II Expansion Project. Since 2000, the JMMCRWRP has delivered more than 28 billion gallons of recycled water to Marathon Petroleum's Carson refinery for boiler feed and cooling tower use. The expansion, which included the installation of a new 5.88 MGD custom-engineered microfiltration (CEMF) system, increases water supply capacity and improves system operability and reliability at the five-acre JMMCRWRP.
