Water Resources Division Identity


The Water Resources Division is dedicated to meeting Livermore's water, wastewater, and storm water utility needs.

The Division delivers drinking water to more than 28,800 residents in Livermore. The California Water Service Company serves the balance of water uses in Livermore.

Recycled water is delivered to more than 160 customers, which includes the City's Golf Course, Airport, and many other landscape irrigation sites. Recycled water also provides fire protection for 58 commercial/industrial buildings in the west part of Livermore.

All of the sewage generated in the City of Livermore is collected and treated at the Livermore Water Reclamation Plant, which is operated and maintained by the Division.

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.

Division staff maintains the stormwater and sanitary sewer systems. The Division also administers a number of mandated regulatory requirements, including industrial pretreatment, pollution prevention and stormwater programs.

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.

Take a Treatment Plant Tour

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.

Drought Update

On April 7, 2017, Governor Brown ended the Drought State of Emergency in most of California, including the Tri-Valley region. The Governor continues to call for “Making Conservation a California Way of Life”. At its May 22, 2017 meeting, the Livermore City Council repealed Stage 1 voluntary conservation at the 10% level. THANK YOU to all who cut water use during the drought. While the drought is over, please use water wisely. Click here for tips on wise water use.

Disposable Wipes are NOT Disposable!

Despite being labeled as disposable, sanitary wipes, toilet cleaners and other similar products labeled as “flushable” can clog underground sewer pipes and cause toilets and sinks to back up or overflow. Sewer backups and overflows cause property damage, potential health hazards and threaten the environment. 

Protect against backups and overflows by following these simple guidelines: 

  • Toilets are not trash cans. Flush only human waste and toilet paper down the toilet.
  • Throw used wipes away in the trash.

Keep Sewers Fat-Free

Did you know that Fats, Oils and Grease (FOG) are bad not only for your arteries and waistline but for your sewers, too? They may not be toxic, but they will clog your pipes and sewer. During the holiday season and year-round, easily and properly dispose of your FOG by following these simple guidelines:

  • DON'T pour FOG into sink drains or toilets.
  • DON'T use warm water and soap to wash FOG down the drain; it will only cause clogs further on in the sewer system.
DO manage FOG properly
  • For small amounts of FOG, scrape out or use paper towels to wipe your pans, and then place the FOG or soiled paper towels in your Food Scrap pail. You can also pour cooled FOG into an old paper milk or ice cream carton, let harden and then place it in your green (organics) cart.
  • For large amounts of FOG, such as used oil from a turkey fryer, collect cooled oil in a sealable container and take it to the Alameda County Household Hazardous Waste Facility in Livermore. Please note that State Regulations limit the amount of waste you may transport to 15 gallons of liquid waste (refers to the actual contents of the containers, not the container size), or 125 lbs solid waste. Individual items/containers must be no larger than 5 gallons or weigh no more than 50 lbs.

No Drugs Down the Drain

While some pharmaceuticals enter the environment via normal human and livestock excretion into sewer systems or waterways, much enters the environment via direct disposal, such as having been flushed down the toilet or poured down the drain. While wastewater treatment does remove and reduce some types of pharmaceuticals, wastewater plants are designed to treat human and biological waste, not complex pharmaceutical chemicals. Because some aquatic species have shown sensitivity to the low levels of medications that do pass through treatment plants, the more medication we can prevent from going down the drain, the better.

The 14th Annual National Prescription Drug Take Back Day will take place on Oct. 28, 2017, to locate a collection site near you, click here or call 1-800-882-9539.  Refer to the Livermore Police Department for more information about the next event.

Be Mercury Free

Mercury is toxic and can cause damage to the nervous system, brain, kidneys and immune systems in humans and animals. Bring your mercury thermometers to the City of Livermore Water Reclamation Plant at 101 W. Jack London Blvd., Monday through Friday, 8 AM to 4 PM and exchange them for new mercury-free ones -- at no cost to you! Have questions or need more information? Contact the Water Resources Division at 960-8100.
