Water Resources Division Identity

The mission of the Water Resources Division is to protect public health and the environment by providing safe, effective and efficient drinkable and recycled water distribution; wastewater collection, treatment and disposal; and stormwater management.


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 provides wastewater treatment and disposal for residents and businesses, produces recycled water for landscape irrigation and other uses.


The Division maintains over 500 miles of sewer collection piping and storm water conveyances which carry wastewater to the treatment plant and floodwaters away from homes and businesses into local creeks and streams.

The treated wastewater that is not recycled locally is sent through the Livermore Amador Valley Water Management Agency (LAVWMA) pipeline for disposal in the San Francisco Bay.

Help Keep Waterways Litter-Free

Plastic bags, bottles, cigarette butts, and other litter gets washed or blown directly into storm drains or directly into waterways, causing local water pollution as well as pollution in the San Francisco Bay. Not only does litter deteriorate water quality, it harms aquatic life, too. Yet litter can easily be prevented. Here are a few easy ways to do so.

  • Pick up one piece of litter each day.
  • Pick up after your pet.
  • Keep garbage, recycling, and organics cart lids closed.
  • If you smoke, use an ashtray and empty the ashtray properly.
  • Report litterbugs by calling the Livermore Litterbug Hotline at 925-371-4766.

Plant Tours Unavailable Due To Improvements

Plant Tours are temporarily unavailable due to improvements being completed at the Livermore Water Reclamation Plant. Plant tours will resume in 2018. In the meantime, you may visit the Livermore Water Reclamation Plant Armchair Tour. You may also view the Water Environment Federation's 3D tour showing how dirty water moves from your home to the water treatment plant.
