Washwater Reclamation Plant Upgrading
Skinner Water Treatment Plant (WTP)
Metropolitan Water District of Southern California
Los Angeles, CA
LEE & RO provided engineering, design, and construction phase engineering services for a $7.5 million washwater upgrading projects at the 600 mgd capacity Skinner WTP. The project included replacement of nine horizontal flocculators with 18 vertical hydrofoil flocculators, replacement of tube settlers and launders, associated structural and electrical systems and motor control centers. Construction was staged to allow at least two of the three treatment trains to be in operation at all times. The project also included upgrading of water quality monitors housed within six concrete monitoring vaults. Upgrading was needed to accommodate additional online monitors, such as turbidity analyzers, pH meters, and particle counters to comply with more stringent EPA requirements.
