The City of Los Angeles Hyperion Sewage Treatment Plant in Playa Del Rey, project C-741 added 20 new digesters that will have a total holding capacity in excess of 50 million gallons of sewage, with a processing rate of 8,000 gallons per minute. Besides the twenty new digesters, Dynalectric furnished and installed eight 15KV electrical power substations, two 35KV electric transformers, walk-in load centers, numerous sections of motor control and all required instrumentation.
