PRESENTATION ITEM— 5D ,-AI�EN HILLS MEMORANDUM DATE: June 20, 2023 TO: Honorable Mayor and City Councilmembers Dave Perrault, City Administrator FROM: David Swearingen, P.E. Public Works Director/ City Engineer Gayle Bauman, Finance Director SUBJECT: Water Meter Replacement & Lead/Copper Inventory Budgeted Amount: Actual Amount: Funding Source: $1,225,000 TBD Water Utility Fund Council Should Consider • Beginning the process to replace the City's water meters over 2023 & 2024 or revisit this item next year. • Hiring a consultant to evaluate the City's existing metering system to provide a recommendation for replacement and transition. Background The City currently has 2,822 meters in its system. 2,513 are designated as Cycle 1 (mainly residential) and 309 are designated as Cycle 4 (mainly commercial). Commercial meters in the City were replaced in 1997. Most residential meters in the City were replaced in 1999-2000. Residential meters were not replaced at that time if they were in good working order and less than 10 years old. This means that the majority of the meters in the City are at least 23 years old with some possibly being up to 33 years old. The Galaxy readers were replaced throughout the entire City in 2012. In late 2020 or early 2021, the City was notified that the Galaxy radio transmitter endpoints that were installed in 2012 would no longer be manufactured, therefore, there are no parts available for replacement if needed. The next option was to utilize endpoints that use cellular transmission. Public Works has been transitioning to the cellular endpoints as the radio endpoints fail. The radio endpoints are said to have a 20-year life before the batteries begin to fail, but we have also learned that if an endpoint struggles to send information to a "collector", it will continue to try and send a signal which will use up battery life. This might be one of the reasons why Public Works has had to make replacements recently. Page 1 of 3
