Rancho Santa Margarita Recycled Watersystem Project

Rancho Santa Margarita Recycled Watersystem Project

The project would entail construction and operation of Santa Margarita Water District (SMWD) infrastructure to extend its existing recycled water service within Rancho Santa Margarita and adjacent unincorporated County land. The project proposes installation of approximately 95,000 linear feet (approximately 18 miles) of 8-inch-, 12-inch-, 16-inch-, and 18 inch-diameter pipes. Most proposed pipelines would run parallel to existing SMWD potable water pipelines beneath existing City and County roads, consisting of Antonio Parkway, Avenida de las Banderas, Avenida Empresa, Santa Margarita Parkway, Avenida de las Flores, Melinda Road, Coto de Caza Drive, and smaller collector streets within residential and commercial developments. A new aboveground reservoir tank would be constructed to store recycled water for distribution flexibility. The new tank is proposed in an undeveloped area on property owned by SMWD north of Los Alisos Boulevard and adjacent to an existing SMWD tank and pipelines. A new pump station is proposed south of the Portola Reservoir on developed SMWD property. The existing Eastbrook Recycled Water Pump Station would be expanded to provide additional pumping capacity. Upon completion, the project would permanently convert an estimated approximately 4,000 acre-feet per year of residential and commercial irrigation demand from potable to recycled water.
