Your top questions, answered.

When will you replace my lead service line?

Each fall, Denver Water identifies work areas for the following year. Several factors drive when and where service lines are replaced. We are not able to estimate timing beyond the current year.

Denver Water prioritizes communities who are most vulnerable and at-risk from lead exposure, particularly infants and children. Areas with large numbers of facilities that serve these populations, such as schools and daycares, are prioritized. Other determining factors include areas with the highest concentration of lead service lines, underserved neighborhoods and coordination with other known construction activity.

With more than 64,000 lead service lines in our service area at the outset of the program, at a rate of about 4,500 replacements a year, the effort to replace lines will be completed by 2035.

Once work areas are identified, Denver Water will determine the timing for individual properties in that work area. Once a property has been identified for a service line replacement, Denver Water will send additional information about the replacement process and next steps. This notification typically comes a month or two before the anticipated replacement date.

How is Denver Water identifying where to replace service lines?

Because service lines are owned by customers, details about the material of a property’s service line have historically been inconsistent and scattered. As part of the Lead Reduction Program, Denver Water developed a comprehensive inventory showing the location of known and suspected lead service lines in our service area using property records, water tests and visual inspection of service lines. 

Denver Water is using this inventory and a sophisticated model, both of which are constantly being updated with new information, to guide decisions about where to look for lead service lines and the timing of replacing these lines.

The model prioritizes replacement areas based on several factors, including:

  • The likelihood that lead service lines are in a given area. 
  • How many properties in a given area are identified as either having or likely to have lead service lines.
  • Identification of the presence of health impacts associated with lead (e.g., elevated blood lead levels).
  • The potential to coordinate replacement work with other efforts to minimize or avoid multiple disruptions to the same community.
  • Census information and other studies that can be used to identify areas where the population is at higher risk for negative health consequences from potential lead exposure (e.g., children and expecting families, median income below the federal poverty level, etc.).

In addition to replacing lead services lines on a neighborhood-by-neighborhood basis, Denver Water is deploying crews to replace lead service lines at critical facilities, including schools, day care centers and other locations, and continuing the work needed to expand and improve the location inventory.
