Inventory Basics Reference Guide

In August 2022, the Environmental Protection Agency (EPA) released a Lead and Copper Rule Revisions (LCRR) guidance and template to support utilities and states with their Service Line Inventory (SLI) efforts.

120Water developed this quick reference guide for water systems to have a map to help them get started on their service line inventory.

The preliminary service line inventory is the basis for compliance. Every program (facility testing, public communications, replacement plans, new tier levels) depends on the preliminary inventory of your system. The goal here is to ascertain what you know – and don’t know - about the materials in your system.
