Residents may notice increased water flow in Oso Creek and San Diego Creek this week, as workers shut down a main supply pipeline to install a connection point for a new water source in South Orange County.
The excess water, which will drain out of the 66-inch supply pipeline after it is shut down for the work, will be recaptured and recycled. The water in the Oso Creek will be captured by Santa Margarita Water District’s Oso Creek Water Reclamation Plant, where it will be recycled and used for irrigation. Water in the San Diego Creek will pond in a settling basin and return to the groundwater basin.
The work will allow a connection to the Baker Filtration Plant, a joint project of five water agencies, including SMWD. When the project is finished, the Baker plant will receive untreated water from the Metropolitan Water District of Southern California and supply more than 28 million gallons of drinking water a day to South Orange County customers.
El Toro, Irvine Ranch, Moulton Niguel and Trabuco Canyon water districts are also partners in the project, which will increase water-supply reliability and water quality. The overall project cost, shared among the partner agencies, is $103.6 million.
The work begins Wednesday and will continue through May 5. South County’s water will be delivered to water agencies from the Upper Chiquita Reservoir or through other supply pipelines during that period.
