Aqueduct & Water Operations

The Water Authority operates and maintains a regional water delivery system capable of delivering 900 million gallons of water per day.

 


Twin Oaks Valley Water Treatment Plant

This system consists of 310 miles of large-diameter pipeline, 1,600 aqueduct-related structures, and approximately 100 metering/flow control facilities. The system also includes a state-of-the-art water treatment plant, hydroelectric facilities, pump stations, flow regulatory structures, and a dam with a 24,000 acre-foot reservoir.

Each year, the Water Authority develops an Aqueduct Operating Plan to communicate and coordinate with member agencies. The plan incorporates on-going efforts to optimize the delivery, treatment and storage of water in the San Diego region.

The plan is a coordinated effort with the Water Authority and its 24 member agencies, the Metropolitan Water District, and other stakeholders. The goal of the plan is to manage the water demands of San Diego County and coordinate maintenance activities and system shutdowns so that all portions of the systems are managed safely and efficiently.  

The water delivery system is monitored and controlled 24 hours a day, seven days a week by state-certified distribution operators to ensure the proper amount of high-quality water is delivered to our 24 member agencies throughout the county.
