Lead Service Line Inventory Program

Early City Efforts to Replace Lead Services Lines

The City began a lead service line inspection and replacement program in 2018 focusing on areas of downtown where lead service lines are more likely to be found due to older building construction. On December 16, 2021, the U.S. Environmental Protection Agency (EPA) put into effect the Lead and Copper Rule Revisions (LCRR) to support plans to reduce lead in drinking water. The rule requires that water providers develop an inventory of lead service lines and a replacement plan by October 16, 2024.

In early 2022 after EPA passed the new rule, City crews began focusing efforts on completing the lead service line inventory across the City’s water service area. To date, the City has inventoried 1,000 properties and identified 84 lead service lines on the city side of the meter and 47 on the customer end. Based on the policy framework issued by the Colorado Department of Public Health & Environment (CDPHE), which is responsible for administering the program, the City estimates that an additional 1,000 properties will need to be inspected.

All service lines within the area between 1st and 19th Streets and North and South Avenues will be inspected based on the older ages of building construction that have the potential for having lead service lines. In addition, a representative number of service lines outside this area with building construction earlier than 1968 will be inspected using the predictive modeling approach required by CDPHE. View the map of Grand Junction homes that have been inspected.

In 1967, the City of Grand Junction issued an ordinance that required that all service lines be made copper, so homes built after 1967 do not have lead pipes and will not be inspected. City crews will be inspecting service lines as weather permits.

The City conducts regular water quality monitoring throughout the distribution system, including testing for lead. The results indicate that lead is below the action level regulated by agencies. If you have concerns about your water quality, City water customers may request a free water quality test by contacting water@gjcity.org.

Lead Service Line Inventory and Replacement Plan

In addition to completing the inventory, the City will be developing a lead service line replacement plan for submittal to the CDPHE by October 16, 2024. While the City is currently only responsible for replacing the City-owned service line between the meter and the main, the City will assist customers with the replacement of the customer-owned water line between the meter and the building. The City has purchased specialized equipment that will enable City crews to replace the service lines at a reasonable cost to the property owner. Where applicable, service line replacements will be scheduled in coordination with any planned water main replacements to minimize disruptions.

    When was this inventory map created? What is the lead pipe status/testing plan for my home at 238 Bookcliff Avenue GJ 81501? Thank you.

    caegh asked 7 months ago

    Thank you for your question.

    The inventory map is updated regularly as we complete inventories in neighborhoods.  As shown by the yellow color on the map for your property at 238 Bookcliff Avenue, the status is "Unknown, Original construction year between 1942 and 1967, Lead pipe less commonly used during this period and discontinued in 1967. Records review and possibly potholing to determine material." City staff will continue to conduct inventories through October 2024 and the map will be updated as data is available.

    How much does it cost to test my home connecting pipes for lead?

    I don’t know what my screen name is? asked 7 months ago

    Thank you for your question.  If your home is identified in the area where City Crews will be testing, your pipes will be inventoried and results will be provided to the homeowner. The City conducts regular testing of water throughout the distribution system.  If you have concerns about the quality of the tap water in your home, the City is able to complete a free water test.
