Milwaukee is quietly sitting on one of the region’s biggest infrastructure decisions: several firms are vying to run the Milwaukee Metropolitan Sewerage District’s two water reclamation plants under a contract that could total as much as $700 million over the next decade. The Jones Island and South Shore facilities handle most of the region’s wastewater, produce Milorganite fertilizer and play a central role in keeping Lake Michigan and neighborhood basements from flooding during heavy storms. Whichever bidder wins will help shape daily operations, emergency response and long-term spending.
The bidding contest, detailed in a photo gallery published April 6, 2026, could be worth up to $700 million over 10 years, according to the Milwaukee Journal Sentinel. The gallery highlights plant infrastructure, and its captions note that the incumbent operator currently runs both the Jones Island and South Shore sites.
In a news post, MMSD said it has started the formal selection process for the contract that will replace the current agreement, which runs through Feb. 28, 2028, and that proposals submitted earlier this year are under review. The agency points to the regional system’s reported performance, saying it captures and cleans roughly 98.4% of the water entering the sewer system, and notes that any new operator will be judged against that mark.
Veolia Water Milwaukee LLC, the long-time contractor that now operates and maintains Jones Island and South Shore, has overseen plant operations, biosolids processing and energy-management efforts under a public-private partnership that began in 2008. Veolia highlights its role in day-to-day operations and resource-recovery work at the facilities.
How the bidding works
MMSD ran a two-stage procurement that began with a Request for Qualifications and then moved to a Request for Proposals posted on the district’s Bonfire portal. The RFP documents and vendor presentations were made available online for potential proposers. The procurement documents and instructions for submitting proposals are archived on public procurement sites and in the district’s Bonfire portal, which handles digital submissions and evaluation materials. Filings on GovTribe spell out the portal setup and requirements for proposers.
What’s at stake for ratepayers
Multiyear operations and maintenance contracts of this size routinely run into the hundreds of millions of dollars and take up a substantial share of a utility’s O&M spending. That reality has framed previous debates over MMSD’s private operating agreements, as industry reporting and earlier local coverage have noted. WaterWorld and earlier local stories have documented how these contracts influence budgets and capital planning.
Why oversight matters
Local watchdogs and some residents say the stakes are not only about money, since operational missteps can lead to waterway contamination and beach closures. A contractor error in March 2025 that sent nearly 10,000 gallons into Lincoln Creek remains a touchstone for critics pressing for stricter field oversight, as reporting on the 10,000-gallon sewage spill documented.
What comes next
MMSD says proposals are being reviewed by an Ad Hoc Operations and Maintenance Contract Selection Committee and that negotiations are underway. The agency’s public schedule lists a tentative public hearing on June 12, an Ad Hoc meeting on June 22 and a final commission action slated for Sept. 28, 2026, according to MMSD. Those meetings are set to be the key public checkpoints for anyone tracking who will run the plants next.
