Replacing Lead Service Lines

Service lines made of lead pose a serious risk to public health. Plumbing professionals can lend their expertise and show their concern for customers' health and safety by encouraging them to replace lead service lines.

Replace, don’t repair

If a lead service line has a leak, it should be replaced with copper in full, not just repaired. Here are the steps:

  1. Obtain permits from Denver Water and the local permitting office.
  2. Call Water Sales Administration at 303-628-6100 to schedule a tap cut at the main.
  3. Excavate.
  4. Replace the existing water supply pipe from the main to the water shutoff inside the home foundation using a continuous type K copper pipe (see Denver Water’s Engineering Standards). If the indoor main water shutoff shows signs of deterioration or malfunction, replace it.
  5. Do not use splices or solder joints. Use lead-free bronze for all fittings at the meter, including the yoke.
  6. Backfill and compact excavations to standard.
  7. Replace the meter pit with new approved material (see the Engineering Standards.)
  8. Schedule and pass all inspections. Contractors are responsible for rework.

Bid opportunity

Denver Water and Denver Urban Renewal Authority (DURA) are partnering to provide no- or low-interest loans to owners of single-family homes or duplexes in Denver Water's Total Service Area who want to replace lead service lines.

DURA solicits contractor bids and oversees the replacements. Contractors who would like to participate should apply with DURA. If you are working with a customer who is interested in a loan and you know their line is made of lead, provide verification such as a signed note and tell the owner to call DURA at 303-534-3872.
