Service Line Inventory

What's Happening Now?

During the spring of 2025, the City plans to work with our plumbing contractor to confirm the pipe material for nine remaining unknown locations. In addition, we will focus efforts on verifying the pipe material at additional locations in the property right-of-way for pipes owned by the City.

Initial Service Line Inventory- Complete

The city has completed its initial inventory of all drinking water service lines in our service area. Our inventory began in 2019 when we inspected service lines during our water meter improvement program. No lead service lines were identified at that time. To complete the inventory, the city used several methods, including records review, customer outreach, onsite visits to homes and businesses, and visual inspections. 

All known residential service lines are determined not to be made of lead. Only nine locations require additional investigation.

About the Project:

The City of Westminster is committed to providing safe, clean, and affordable drinking water for our community. Our drinking water consistently surpasses state and federal drinking water standards. We continually monitor water quality to ensure our water continues to be exceptional. View our water quality report.

Over the past few years, the Environmental Protection Agency (EPA) has released regulatory updates for water service providers known as the Lead and Copper Rule Revisions (LCRR). In response to the LCRR's new requirement for a water service line material inventory, we are building out and confirming our inventory of residential service line material in Westminster. A water service line is the pipe that brings water from the water main to your home.

The EPA requires that the City have two forms of verification for service line material on the public and private side of the service line. The first point of verification was completed during our water meter improvement program in 2019. Each side on the meter was visually inspected inside of the meter pit, and no lead service lines were identified at that time. The city-owned side and homes built after 1960 have received their second point of verification and are now complete.

To date, we have only identified copper water service lines in Westminster homes; however, there may be galvanized steel service lines in some older homes. Galvanized steel pipes are coated with zinc to prevent rust and deterioration. Some galvanized service lines in service before 1961 may need to be replaced as part of the LCRR regulation.

Timeline

• 2019: First point of confirmation on public and private service lines was visually inspected on both sides during the water meter improvement program.
• Fall 2023: The Colorado Department of Public Health and Environment (CDPHE) released additional guidance criteria for the Service Line Inventory. The second point of verification was completed for service lines less than 4 inches or installed after 1960.
• Summer 2024: Second point of confirmation on customer-owned service lines older than 1961 will be completed.
• Fall 2024: The inventory will be made publicly available.

Voluntary Home Inspections

Based on the criteria outlined in the CDPHE policy DW018, the City is now investigating the second point of verification for the customer side of the service lines installed prior to 1961. The City has hired a certified plumbing contractor, AGL, to complete these second verifications. AGL will be contacting property owners of buildings that were constructed prior to 1961 about voluntary visual inspections of the service line material on the inside of the building. Our goal is to keep residents safe from pipes that may contain lead.

What to Expect

To complete the inventory, the following tasks may be completed:

• Customers will receive a mailer with information on how to schedule your plumbing materials inspection.
• AGL will collect customer information, including photos of where the service line enters the building on the interior (basement or crawl space).
• Our certified plumbing contractor, AGL, will not enter a home or private property unless we receive permission and have coordinated with the homeowner. Westminster staff will attend in addition to AGL staff at the request of the homeowner.
