Three years after it started, Denver Water’s Lead Reduction Program is getting a big boost from more than $76 million in federal funding. 

The funding will help fast-track the program, replacing thousands more old, customer-owned lead service lines in the next few years than had been originally anticipated. 

The state approved allocation of funds to Denver Water in October, and the Denver Board of Water Commissioners formally accepted the funds Dec. 7. 

The money will be spent in 2023 through 2025 and is expected to replace up to 7,600 lead service lines, shortening the 15-year program by 1.5 years. Thanks to the new funding, between 3,000 and 5,000 additional lines will be replaced in 2023 — on top of the nearly 5,000 lines already planned for replacement next year.

Since the program started in January 2020, Denver Water has replaced more than 15,000 lead service lines. The lead lines are replaced with lead-free, copper lines at no direct cost to the customer.

“This infusion of federal money means we will be able to replace thousands more customer-owned lead service lines at a faster pace than we had originally planned, and ultimately shorten the length of the biggest public health initiative in Denver Water’s history. This groundbreaking program is supported by all our customers across our service area,” said Jim Lochhead, Denver Water’s CEO/Manager. 

“Removing these lines is the most effective way to eliminate this source of lead exposure, and we are committed to this program until every lead service line has been removed. We’re grateful for the opportunity provided by this funding.”

The water Denver Water delivers to customers is lead-free, but lead can get into the water as it passes through a customer’s internal plumbing or water service line that contains lead. The service line is the small pipe that connects to Denver Water’s pipe in the street and carries water to the customer’s home. Lead can cause serious health problems if too much enters the body, whether from drinking water or other sources

Denver Water’s groundbreaking Lead Reduction Program aims to replace nearly 5,000 customer-owned lead service lines every year. When the program started, Denver Water estimated there were between 64,000 and 84,000 lead service lines in its service area and expected it would take 15 years to remove them all. 

For every 4,500 additional lead service lines replaced using the federal funding, the overall length of the program will be one year shorter.

Replacement work will take place in parts of many neighborhoods across Denver in 2023, including Baker, Globeville, Sunnyside, Barnum West, Athmar Park and Capitol Hill. 

An initial map of the 2023 replacement work areas is available at The replacement work prioritizes areas with vulnerable, at-risk populations and disproportionately impacted communities while also taking into account planned construction activities, schools and child care centers.

Lead was a commonly used material for water service lines across the U.S. through the mid-1900s and is frequently found in Denver homes built before 1951.

The replacement work is done by contractors through the Lead Reduction Program and by Denver Water crews, who replace any lead service line found during scheduled pipe replacements or during repair work on a broken water main. 

In total, Denver Water was approved for $76,123,628 from the Colorado Drinking Water State Revolving Fund, which will receive money from the federal bipartisan Infrastructure Investment and Jobs Act signed into law by President Joe Biden in November 2021. The funding Denver Water received is a low-interest loan that the utility will repay, with $40 million of the loan’s principle forgiven immediately as allowed by the legislation.

The state will receive federal funding from the Environmental Protection Agency to address lead in drinking water every year for five years, beginning in 2022. Denver Water intends to apply for funds in the future and, if approved, will be able to accelerate the replacement program even more.

The EPA also has approved a continuation of the Lead Reduction Program, via a variance from the federal Safe Drinking Water Act, following a review of the progress made in its first three years. 

“Denver Water’s approach to tackling lead in drinking water has been remarkable and an example for other communities across the country,” said EPA Regional Administrator KC Becker, in an announcement.

“Thanks to new funding from the Bipartisan Infrastructure Law the utility’s customers can expect an even faster lead service line replacement schedule delivering health protections for children and adults across the Denver area.”

Lochhead thanked EPA and Denver Water’s community partners for working with the utility to ensure the successful implementation of the program. 

“Denver Water’s first priority is sustaining our communities by protecting the health of our customers,” Lochhead said. 

In addition to the installation of a new, lead-free, copper water service line at no direct cost, customers enrolled in the program also receive water pitchers and filters certified to remove lead.

Filtered water should be used for cooking, drinking and preparing infant formula until six months after the lead service line is replaced. The utility also has changed the water chemistry, raising the pH of the water it delivers, to better protect customers from the risk of lead.

“This has been a huge effort involving many areas of Denver Water, and we couldn’t have done it without the support we’ve received from our customers,” said Alexis Woodrow, who manages the Lead Reduction Program for Denver Water.

“Our customers enrolled in the program allow us into their homes to replace their old lead service lines, and they are patient with all the construction work that accompanies the replacement process. We’re also excited that in a recent survey, 83% of customers said that they use the filters we provide to filter water for cooking, drinking and preparing infant formula.” 

With the federal funding, the work surrounding the replacement process will touch more homes and neighborhoods in 2023. 

“We’re grateful for all the support we’ve received for this program, from our customers to our community partners and our elected officials,” Woodrow said. 

“We’re all working to protect our customers now and for generations to come.”
