> Facilities > LAVWMA System
LAVWMA's facilities span from the City of Livermore to the San Francisco Bay. The System Map shows an overview of these facilities.
At the Pump Station, the water is combined and equalized in LAVWMA's three storage basins, which can hold up to 18 million gallons of water. The reservoirs allow LAVWMA to store water during large rain events and provide flexibility during summer months to operate the pump station during off-peak energy hours when electricity is least expensive. The LAVWMA pump station consists of ten 500-600 horsepower pumps which push the water through the LAVWMA pipelines over the Dublin Grade to San Francisco Bay for disposal.
The Export Pipelines range in size from 24 to 36-inches in diameter and span approximately 15.6 miles. The export pipelines pass through Pleasanton, over the Dublin Grade, through Castro Valley, San Lorenzo, and San Leandro. At the San Leandro marsh, the LAVWMA export pipeline empties into an outfall owned by the East Bay Dischargers Authority (EBDA).
EBDA discharges the treated wastewater to the Bay through a Deep Water Outfall near the Oakland Airport for optimal dilution with Bay waters. LAVWMA also has an emergency dechlorination facility and bypass pipeline to discharge into the San Lorenzo Creek in case of an interruption in EBDA's service.
All three LAVWMA member agencies are actively involved in water recycling. Some of these efforts are directly tied to the current drought in California, but other projects have been ongoing for many years. DSRSD works closely with the San Ramon Valley Recycled Water Program to provide recycled water to DERWA (a joint project between DSRSD and East Bay Municipal Utility district) for golf courses and other landscaping projects. City of Pleasanton is developing a recycled water project to provide water to various parks and street medians. In Livermore, recycled water is pumped to the Doolan Tank where it is stored for irrigation, fire protection, and fire suppression uses. Additional information can be found at each agency's website.
