Voluntary Water Service Line Self-Reporting

We need your help!

Please help us by completing the water service line self-identification form below.

On January 15, 2021, the U.S. Environmental Protection Agency (EPA) issued Lead and Copper Rule Revisions (LCRR) that went into effect on December 16, 2021. The LCRR requires jurisdictions to collect and submit service line inventories to the Washington State Department of Health (DOH). The City of Redmond is required to follow this updated rule. We do not anticipate a lead service line issue in Redmond, but we need to collect this info for the EPA and DOH.

Your private water service line could be made of different materials depending on the age of your plumbing fixtures: lead, galvanized steel, copper, or plastic (see examples below).

To determine the material of your service line:

  1. You will need a key or, a coin, and a strong refrigerator magnet.
  2. Look for your service line behind your water meter or inside your home where your plumbing first enters your basement or crawlspace. Your water meter will be located in a box at the edge of your property facing the street, curb, or sidewalk. Your service line may be accessible from the meter box or easily excavated just behind the meter box towards your home.
  3. Carefully scratch the pipe with a key or coin.
    Do not use a knife or other sharp tool. Take care not to make a hole in the pipe – be gentle and do not put pressure on or hit the pipe. Only complete this step if you can do so without damaging the pipe.
  4. If the scratch turns a shiny silver color, it could be lead or steel. Note: if the pipe is painted, gently scrape off the paint first to expose the metal.
  5. Place the magnet on the pipe.
    If the magnet sticks, it is steel. It is a lead pipe if it’s silver or grey and is not magnetic.

Please complete the Self-Identification Form below. Select the material that the private portion of your service line is made of and, if possible, upload a picture of your meter that we can use to help identify the pipe material.

Feel free to reach out to us or a licensed plumber with questions. Please call (425) 588-2850 or email us at LSL@redmond.gov to request a visual inspection of your pipe material at your residence or business.
