DENVER WATER BOARD Lead Service Line Inventory
Denver Water serves about 1.3 million people across the Denver metro area. Like water systems nationwide, it may have lead service lines—the pipes that connect homes to the main water line under the street. Lead can leach into drinking water, especially in homes with older plumbing or where water is corrosive.
What we know about Denver Water's lead pipes
Denver Water has not yet published a detailed inventory of lead service lines in its system. This means the utility has not yet released a public count of how many lead pipes it has identified, where they are, or how many are still in use.
As of now, there is no updated inventory available online through LeadPipeCheck or the utility's website.
Why an inventory matters
Federal law (the Lead and Copper Rule) requires water systems to locate and catalog lead service lines by a deadline in late 2024. An inventory helps:
- Homeowners learn if their address has a lead line
- The utility plan replacement work
- You take interim steps (like flushing or using filters) if needed
What you can do now
Even without a published inventory, you have options:
Contact Denver Water directly. Call or email to ask if your address has a known lead service line. The utility can often tell you based on property records and previous testing. They may also offer free or discounted testing if you request it.
Test your water. If you're concerned, a simple lead test costs $20–50 and takes a few days. Denver Water can direct you to an approved lab. Results are your baseline for your home.
Know your pipes. If your home was built before 1950, lead pipes are more likely. Homes built 1950–1980 may have galvanized steel lines (which can also corrode and release lead over time).
Check for updates. Denver Water is working to complete its inventory. Check back with the utility or this page for updates when the inventory is published.

Frequently asked
Does Denver Water have lead service lines?
Possibly. Denver Water has not yet published a detailed public inventory, so it's unknown how many lead lines exist in the system. The utility is required to complete this inventory by late 2024.
How do I know if my home has a lead service line?
Contact Denver Water directly and ask about your address. They can often check property records and past water tests. You can also request a water test to check for lead in your home.
Is lead in drinking water dangerous?
Yes. Lead can cause serious health problems, especially for children and pregnant people. Contact your doctor or the CDC if you have health concerns. The safest approach is to assume risk and test or filter if you're in an older home.
What should I do if I think my water has lead?
Request a free or low-cost test from Denver Water, use a certified lab, or install a lead-removal filter (NSF-certified for lead). Let tap water run cold for 30 seconds before drinking if your home has old pipes.
