The City of Livermore Water Resources Division manages and maintains Livermore's wastewater (sewer) system. Livermore relies on a network of more than 300 miles of sewer mains and four lift stations to transport wastewater from individual properties to the Livermore Water Reclamation Plant for treatment.

The Livermore Water Reclamation Plant treats 2.2 billion gallons of wastewater each year. 1.6 billion gallons of this treated wastewater is discharged into San Francisco Bay, while the rest is used locally as recycled water.
