Lead Service Line Inventory
New state and federal laws require us to inventory all water service lines in our service area. A service line is the underground pipe that carries water from the water main, likely in the street, into your home or building. We need to determine the material that your service line is made of, which means we will need your help.

Most service lines in Colorado are non-lead (e.g. copper or plastic). Lead service lines became less common after 1950, but could have been used until the 1988 state ban on lead pipe, unless there was an earlier local ordinance or control. Service lines are often copper, plastic, lead, or galvanized iron or steel. Older homes and buildings may have a lead service line. Drinking water is free from lead when it leaves our water treatment plant. However, water can absorb lead as it travels through lead pipes on its way to your faucet. Lead can cause serious health problems. If you have a lead service line, we need to take steps to reduce your lead exposure risk. Knowing your service line material is very important for your health and safety!



Home Plumbing with customer owned service line

Use the information below to check your water service line material:

  • Locate and visually inspect the service line as it enters the house or building, if accessible. This is usually located on the lowest floor or crawlspace facing the street. The service line is usually either the pipe sticking out from the foundation wall, or coming up from the ground before reaching a shut off valve (see photo right). Be careful not to confuse the line with the sewer or gas line. Homes built after 1988 are not expected to have lead service lines or lead plumbing. Search the county assessor's office records or realty websites such as Zillow to check your home’s build date.
  • Do a scratch test: Gently scrape the pipe using a coin or the flat edge of a screwdriver to reveal the metal. Do not use a knife or sharp object. If the pipe is painted, gently sand or scrape the paint away first to expose the metal.
      • Lead pipes are usually dull gray and easy to scratch. If the scratched area appears shiny silver and flakes off, the pipe could be lead.
      • Galvanized steel is gray to silver in color and harder to scratch. If the scraped area is dull and gray, the pipe is likely galvanized steel.
      • Copper pipes are copper to bronze in color. If the scraped area is copper in color, similar to a penny, the pipe is copper.
  • Plastic pipes are usually white, glossy black, or colored. Plastic pipes are rigid and non-metallic. A scratch test is not needed to identify plastic pipes.
  • Use a magnet, such as a refrigerator magnet, to see if it sticks to the pipe.
    • A magnet will not stick to lead or copper pipe, but will stick to galvanized steel.
  • Lead swab kits can be purchased online or at a home improvement store. These kits test the pipe surface, not the water inside the pipes. Look for an EPA recognized kit.
