Water

Background

The city's water source is the Indian Creek Reservoir, which is held by an earthen dam built in 1989 and fed by Indian Creek. Our treatment process utilizes water treatment technology to remove both particulate matter and dissolved contaminates from the water before it is disinfected and pumped to the distribution system for delivery to homes or businesses in the water service area.

Lead Service Line Inventory

 On January 15, 2021, the U.S. Environmental Protection Agency (EPA) issued Lead and Copper Rule Revisions (LCRR) that went into effect on December 16, 2021. Group A Community and non-transient non-community (NTNC) water systems are required to follow the LCRR, which is located in 40 CFR 141. At the same time, EPA announced that it was going to begin new rulemaking to update these same requirements, which they identified as the Lead and Copper Rule Improvements (LCRI). The part of the LCRR not expected to change in the LCRI is the requirements relating to the Lead Service Line Inventory or LSLI. All other requirements of the LCRR are subject to change under the LCRI. 

The rule requires all community and non-transient non-community (NTNC) Group A water systems to submit service line inventories to the state by October 16, 2024. This requires water system to dedicate efforts to review historic records and determine appropriate identification methods to obtain both private and utility owned service line information.
