  • Auburn's water, unlike that of other cities, comes from deep well aquifers and springs. It is not dependent on the Cascade Mountains' snowpack replenishing open reservoirs. The City is responsible for the repair and maintenance of the water service lines from the street to the backside of the service meter. The owner is responsible for the service from the backside of the meter to the home. All plumbing in the home and landscape irrigation systems is also the responsibility of the owner. Backflow prevention devices are required on all irrigation systems and fire lines.

    Residents are billed according to the amount of water used. The City has established an inclining block rate for the quantity of water consumed to promote water conservation.


    The City of Auburn Water Department is doing water system repairs. We will be shutting off water

    Tuesday, August 15, 2017 from 8:00 AM to 3:00 PM in the following location:

    Trail Run Development - south of S 277th Street, east of L Street NE,                               north of 49th Street NE, and west of Pike Street NE.

    Please see the map (PDF) for more details.

    You may also notice some water discoloration or sediment following repairs. The sediment and discolored water are not a health hazard and are not a cause for concern.  

    Customers should avoid water use during the maintenance event. We recommend the following.

    • If possible, please keep valves closed during the work time period of 8:00 AM to 3:00 PM. 
    • If you experience discolored water after the work period, follow these steps before using your water:

      1. First, open the outside faucet closest to your water meter and run water until it flows clear.

      2. Next, flush a toilet or run water into a bath tub until the indoor water is clear.

      3. Once your water is running clear, you may resume normal water use.

    We regret any inconvenience this may cause and appreciate your patience. If you have questions or experience any problems or damages because of discolored water due to this water system maintenance, please contact us at 253-931-3048. We are working to provide you with safe, reliable and adequate water service. 

    Safe Drinking Water in Auburn

    In response to concerns about water quality in other parts of the country and about lead and other metals that can leach from a home's water piping into the customer's water, the City of Auburn Water division wants our customers to know the following facts about Auburn's water supply:

    • The City conducts water quality testing frequently throughout the year at our supply sources and in the distribution system. The results of our testing program are summarized in our annual water reports listed on the this webpage.
    • Water from the City's wells and springs receive treatment to adjust the pH so that it is not corrosive to metal piping.
    • pH testing throughout the City confirm that the water is meeting a pH level of 7.8 that minimizes the potential for corrosion.
    • The City of Auburn conducted lead and copper testing in 2015; the results were below state and federal water standards.
    • The City has replaced many older pipelines where lead fittings between the water main and customers' water meters may have been present.
    • The City has a program that regularly looks at water main replacement needs within the water system and provides the funding to construct these replacements.
    • Auburn residents who receive water service from one of the following utilities should contact those utilities directly with any questions or concerns:
    • Southern part of the Lakeland Hills - City of Bonney Lake, 253-862-8602
    • West Hill - Lakehaven Utility District, 253-941-1516
    • Northern Lea Hill - Water District #111, 253-631-3770 or City of Kent 253-856-5600

    If you live in an older home built before 1945, you may want to adhere to the following precautions:

    • Run the water from a tap for 2 minutes before drinking if the water has not been run for 6 hours or more. If there is lead solder in your house's piping, lead can accumulate in the water within the piping if the water sits for a long period. Running the water will flush contaminants out.
    • Always use the cold water tap for cooking or drinking since warm water can be more corrosive than cold water.
    • Never make baby formula or other drinks or food for children from the hot water tap. Use water from the cold water tap (after flushing) and warm if necessary.

    If you would like to test your home's water to see if lead is present, and if levels are cause for concern, the Department of Ecology has a list of accredited water quality labslinks to external site that can perform the testing. 

    Lab search tip: To search for a water quality lab from Ecology's website, choose King or Pierce County, check the box that says "Show only Labs that accept General Public and Commercial samples", and click Select Lab in Washington. Choose a city that is convenient for you, and make sure the lab performs tests on drinking water and metals.

    The City of Auburn is committed to providing its customers with drinking water that meets all state and federal water quality standards. If you have any further questions, please contact City of Auburn Community Development and Public Works Department - Engineering at 253-931-3010.


    The City of Auburn does not add fluoride to its drinking water. Fluoride levels at or below 0.2 mg/L are naturally present in the groundwater. Please check the Fluoride Map (PDF) for fluoride levels where you live.

    Water Conservation

    Water conservation is always encouraged, whether we are experiencing a drought or above normal rainfall. 

    Here are some simple, effective conservation ideas:

    • Only operate automatic dishwashers and clothes washers when they are fully loaded. Set the water level for the size load you are washing.
    • Take shorter showers and replace your showerhead with a low-flow showerhead. Low flow showerheads are available, free-of-charge, to Auburn water customers at the Customer Care Center, City Hall Annex second floor.
    • Replace your old, high-water-use toilet with a low flow toilet. For information on Auburn's toilet rebate program, visit the city's website at Frequently Asked Questions - WaterSense Toilet Rebate Program (PDF).
    • Turn off the tap when brushing teeth. Letting the faucet run can waste up to 4 gallons of water.
    • Do not wash your cars or recreational vehicles at home; use commercial car washes that recycle water.
    • Consider drought-tolerant plants as you plan your garden this year.

    Avoid Cross Connections

    The City of Auburn water system provides drinking water that is safe to drink and meets all State Department of Health and Federal health standards.

    One of the concerns of the Washington State Department of Health involves drinking water cross connections. A cross connection is any connection between a safe drinking water source and a unsafe source of water or liquid. This connection presents a health risk and needs to be eliminated or controlled. For more information on eliminating or controlling cross connections, download this helpful brochurelinks to external site .

    If you need help determining what type or where to install a backflow device, or the safety of your plumbing with regards to backflow, please contact the City of Auburn Cross Connection Control Specialist at 253-931-3064. You may also request a Water Usage Survey Questionnaire or an on-site survey at the same number.

    Backflow devices need to be tested annually to ensure that they are functioning properly to protect your health and to prevent contaminants and pollutants from entering the public water system.  The customer is responsible for hiring a certified backflow testing company to perform this annual test.  For information about companies who are registered to perform backflow assembly testing in the City of Auburn, consult the City's "2017 City of Auburn Registered Backflow Assembly Testers" list (PDF).
