The City of Livermore Water Resources Division provides four vital services to the community - drinking water, wastewater, recycled water, and stormwater management. Through these services, we are able to protect public health and the environment. 

The Water Resources Division is responsible for the operation, maintenance and periodic replacement of the City's water, recycled water, sewer, wastewater treatment and storm drain systems.  It operates and maintains the Livermore Water Reclamation Plant which treats all of Livermore's wastewater and produces recycled water that is used locally for landscape irrigation and fire protection.

Water Resources Division Sections

The Water Resources Division has seven sections that work together to provide our customers with the best quality service 24 hours a day. 

The Administration Section provides administrative and management support to the entire Water Resources Division.

The Maintenance Section consists of mechanics, electricians, and instrument technicians who keep all the equipment and infrastructure running in tip-top shape.

The Laboratory Section analyzes water and wastewater samples to aid optimization of the wastewater treatment processes and to demonstrate compliance with permit requirements. The Lab staff prepares permit-related reports for submittal to the State of California.  On average, they analyze 6,000 to 7,0000 samples each year.

The Source Control Section manages the Industrial Pretreatment Program, pollution prevention, and a number of the City’s stormwater programs.  The Pretreatment Program issues Wastewater Discharge Permits, conducts facility inspections, collects Compliance Monitoring samples, and issues Notice of Violations and resolved issues of non-compliance. 

The Collection Systems Section is responsible for managing and maintaining Livermore's sewer and storm drain systems. This section operates and maintains over 300 miles of sewer mains, thousands of sewer laterals, and four pump stations. 

Wastewater Operations Section is responsible for operating the Livermore Water Reclamation Plant, which treats 2.2 billion gallons of wastewater each year.  About 1.6 billion gallons of this treated wastewater is discharged into the San Francisco Bay, while the rest is used locally as recycled water.   

Municipal Water/Recycled Water Systems Section is responsible for managing the Livermore Municipal Water and recycled water distribution systems. In addition to ensuring the quality and pressure of the potable water and recycled water deliveries, the Section performs water sampling and monitoring, permit compliance reporting, water demand projections, pump station maintenance, reservoir site readings and maintenance, main and service line repairs, fire hydrant replacement and maintenance, and water meter installation and repair.
