City of San Diego

San Diego, CA

The City of San Diego produces 5.5 mgd of 300 mg/l TDS water utilizing General Electric’ EDR units and produces up to 12 mgd of recycled water by blending.  LEE & RO designed new EDR units and other facilities to house the future Advance Water Treatment pilot plant.  The new EDRs required expansion of the existing infrastructure including piping & valves, electrical & controls, and structures.  The $2.5 million project also included new vertical turbine feed pumps with VFDs, new electrical building, new duct banks, and power feeders.
