Grand Rapids officials outline water system condition, risks and $160M five‑year capital estimate
Summary
Public services and water staff briefed commissioners on the city’s water system (1,300 miles of mains, 83,000 accounts, 320,000 people served), updates to the master plan and asset-risk programs, lead service-line work and capital funding needs.
City water-system officials gave commissioners a technical briefing on the system’s history, condition, regulatory obligations and near-term capital needs, saying the distribution system serves roughly 320,000 people and includes about 1,300 miles of water main.
Wayne Jernberg, the city’s water system manager, described the system’s scale and operations: the utility manages 16 storage reservoirs, 11 pump stations and 13 pressure districts, treats an average of about 36 million gallons per day in winter (rising to 70–75 million gallons per day in summer) and supplies 83,000 retail accounts plus several wholesale customers. The system draws raw water from Lake Michigan and operates round‑the‑clock treatment and SCADA monitoring.
Why it matters: Commissioners asked for an updated picture of system reliability and investment requirements after recurring mains breaks and as the city updates its five‑year comprehensive master plan (CMP). The briefing outlined methods the utility will use to improve prioritization of buried‑asset work and to estimate construction needs and costs.
Key technical and financial points cited by staff: - Lead service lines: staff reported the city has replaced about 7,000 lead service lines since 2017 and said roughly 19,000 remain to be replaced; the lead-and-copper rule and replacement requirements drive a large portion of near-term capital work. - Risk modeling: a 2020 external probability-of-failure assessment identified some high-risk segments, but Jernberg said that only 44 of the 397 water‑main breaks since 2020 were among segments the earlier model had flagged (about an 11% match). To improve accuracy, the city is acquiring AquaTwin asset‑analysis software and will run in‑house probability and consequence‑of‑failure modeling tailored to local factors. - Capital needs: staff presented an initial five‑year capital estimate of about $160 million for FY26–FY30 to address mains, storage, treatment and related work; staff said the estimate relies on a combination of rate revenues, state revolving loans, grants and other financing and emphasized the city’s use of low‑interest DWRF loans when available. - Ongoing and planned projects: recent work includes replacement of upflow clarifiers at the treatment plant, reservoir and pump‑station improvements and upgrades to critical transmission mains. Near‑term projects cited include plant chemical containment and carbon feed improvements, large water‑main replacements (for example, two miles on Burton/Division/Kalamazoo), and continued lead‑service replacements.
Staff also briefed the commission on system operations: water staff use CityWorks and GIS to track preventive and corrective maintenance (valves, hydrants and tanks), maintain an on‑call roster for after‑hours emergencies and coordinate responses that aim to keep positive system pressure (to reduce contamination risk). Jernberg reiterated that not every break is predictable but said improved modeling, combined with coordinating buried‑asset work with surface‑street projects, should improve project prioritization and reduce emergency risk over time.
Ending: Commissioners asked for additional detail on how the SCADA modernization (already budgeted) and the new risk‑modeling software will be phased into the capital plan. Staff invited commissioners to tour the filtration plant and said they will return with CMP outputs, a prioritized capital plan and funding options in time for the FY26 budget process.
