City hears 20‑year drinking water master plan urging asset maintenance and a 1% annual waterline replacement goal
Summary
City engineers and consultants presented a 20‑year drinking water master plan recommending recurring maintenance, targeted capital projects, and a long‑term 1% annual waterline asset replacement goal to preserve system reliability; presenters warned main breaks lowering pressure below 20 PSI would create MDNR public‑health concerns.
City Engineer Lauren Snyder introduced a 20‑year drinking water master plan prepared by Lamp Ryerson; consultants Grant Ziebold and Chad Harrington summarized the plan’s maintenance and capital recommendations and the projected budget in 2023 dollars.
Presenters emphasized recurring maintenance (storage cleaning, chemical feed upkeep), replacement-cycle goals and capital projects timed to anticipated growth. The plan frames a 1% annual waterline asset replacement as a long‑term goal: "1% waterline asset replacement theoretically leads to a new system every hundred years, with PVC pipe having an expected life of a 100 years," the presenter said, and consultants warned that increasing main breaks could reduce pressures below 20 PSI — a condition MDNR considers a public‑health hazard.
