 Progress Report: Eliminating Lead Water Pipes in Tucson
For over 30 years, Tucson Water has removed and replaced lead service lines, which can be a major source of lead in drinking water. So far, we’ve replaced 866 lead lines and launched the Get the Lead Out program (2016), along with informational materials for customers. When the U.S. Environmental Protection Agency (U.S. EPA) revised the Lead and Copper Rule in 2021, Tucson Water was ready to meet these stricter requirements.
Our main goal under the new rule is to create a complete list of all water service lines, including 250,000 connections for homes, schools, and businesses. This involves identifying what material a service line is made of on both sides of the meter—from the water meter to your home and from the water meter to the main water system.
Here’s what Tucson Water is doing to prepare our list for the Arizona Department of Environmental Quality (ADEQ):
Assembling a Project Team: We brought together experts in mapping, records, water quality, customer engagement, engineering, and more. We are also working with other City of Tucson departments to coordinate our efforts.
Reviewing Records: We are looking through public records, permits, and maintenance documents to build a profile for each service line. We’re using Artificial Intelligence (AI) to help organize information from utility work orders and other sources.
Conducting Field Tests: We are testing 1,200 locations to check the materials of service lines. These tests can include visual checks, scratch tests, and photos, all collected through a special app. If we need to learn more, we conduct deeper investigations.
Reaching Out to Schools: We’re identifying childcare centers and elementary schools to share information about lead and how to keep children safe.
Working with ADEQ: We’re in touch with ADEQ to update them on our progress and get approval on our service line inventory.
Funding: We’re using $6.95 million from the Water Infrastructure Finance Authority of Arizona to help meet the new requirements and keep our water safe and secure now and for future generations.
Soon, Tucson Water will have an interactive online map that shows what materials are used in specific service lines, which will be searchable by address. We’ll also be reaching out to customers to help Tucson Water identify any unknown service line materials.
