What is different about water line repair and replacement in Denver?
If your home is in the program, Denver Water schedules the replacement and provides a water filter to use in the meantime. That changes the usual advice: a homeowner who hires a plumber to replace a lead line without checking may pay for work the utility would have done.
A leak is a separate situation. A service line that is leaking now needs attention regardless of the schedule, so call Denver Water as well as a plumber and ask how a leak on a suspected lead line is handled. Lines here are buried deep to stay below frost, which adds to excavation, and many are replaced by pulling or boring new pipe.

Water Line Repair and Replacement questions from Denver
How do I find out if my Denver home has a lead service line?
Denver Water has an online lookup showing what is known about each address, and homes in the Lead Reduction Program are notified. You can also check the pipe where it enters the house: lead is dull gray, soft and non-magnetic.
Should I pay a plumber to replace my lead service line in Denver?
Check with Denver Water first. If your home is in the Lead Reduction Program, the utility replaces the customer-owned lead line at no direct cost to you. Paying privately usually makes sense only if you cannot wait for the scheduled replacement.
