Valencia Water Reclamation Plant

The Valencia Water Reclamation Plant (WRP) is located at 28185 The Old Road in the city of Valencia. The plant occupies 27 acres west of the Golden State (5) Freeway. The treatment plant was placed in operation in 1967, and initially had a capacity of 1.5 million gallons per day of secondary treatment. To read more about the typical wastewater treatment and water reclamation process, click here.


The Valencia WRP is a tertiary treatment plant with solids processing facilities. The plant provides primary, secondary, and tertiary treatment for 21.6 million gallons of wastewater per day (see flow diagram below). The Valencia WRP processes all wastewater solids generated in the Santa Clarita Valley Sanitation District (i.e. from the Saugus and Valencia WRPs). The wastewater solids are anaerobically digested, stored, and then dewatered using plate and frame filter presses. The dewatered cake, or biosolids, is hauled away for composting. Methane gas is produced during the digestion process and is utilized to generate steam to heat the digesters.
