A water system between two contracts
Published 13 October 2026
Before the switch became a date in a public-health crisis, Flint had a water plant that was used only intermittently. The city's water system began under private ownership in 1883, and the city bought it in 1903. Detroit supplied treated water under a contract signed in December 1965. Flint treated river water before it moved to Detroit-supplied water in 1967. For the next several decades, the local plant was a backup rather than the everyday source. The March 2016 Flint Water Advisory Task Force report says it operated four times a year to maintain emergency readiness and received periodic upgrades for that purpose. That was the starting condition of the facility later asked to supply the city continuously. A plant kept ready for an emergency and a plant responsible for every day's drinking water had different operating roles, even though the physical site was the same.

The task force placed the water decisions inside a city that had already lost much of its population. Its background section records a decline from more than 200,000 residents in 1960 to fewer than 100,000 by 2014, with a loss of more than a fifth since 2000. About 57 percent of the remaining population was Black or African American. The report described 41.6 percent of residents as living below federal poverty thresholds and the median value of owner-occupied housing as $36,700. These were background measures cited by the task force, not measurements of damage caused by the later water switch. They show the community's circumstances before the full effects of the crisis were assessed. The report also described poor county health rankings, making clear that the new exposure arrived in a place with existing health and economic burdens.

The Detroit contract's initial thirty-five-year term ended in 2000, after which the agreement renewed annually unless either party terminated it. Flint was a wholesale customer, subject to the rate-setting arrangements applied to the other communities buying water from the Detroit Water and Sewerage Department. The task force calculated that charges to Flint rose at an average annual rate of 6.2 percent during the final ten years of that service. It also recorded that Detroit's supply had received corrosion-control treatment for more than twenty years and was considered optimised for that purpose. The dispute over cost therefore concerned a supply that already had an established treatment regime. Leaving that contractual arrangement would also mean deciding how to replace the water and its treatment. F090, michigan.gov, Flint Water Advisory Task Force final report, March 2016
By late 2012, according to former state treasurer Andy Dillon's account to MLive, the Treasury Department had heard the proposal for Flint to leave Detroit's service and join the Karegnondi Water Authority. Dillon said local leaders wanted control over their source and that relations with Detroit had been poor. The alternative Dillon heard about was joining the Karegnondi Water Authority and its new water pipeline. Flint had explored alternatives for years, but a decision involving a substantial expenditure now needed approval from the state treasurer while the city was under an emergency manager. Dillon also recalled pressure to decide because the authority needed to know what size pipe to build. These are his retrospective descriptions of the discussions. They explain the timing and preferences he reported, without establishing that a deadline made a particular interim source necessary.

The task force's chronology records warnings before the agreements were complete. In January 2013, environmental-department employee Mike Prysby emailed colleagues about the feasibility of the river option and highlighted water-quality concerns.

Treasury was not itself a water-treatment agency. MLive reported that it involved the Department of Environmental Quality and commissioned a February 2013 engineering assessment from Tucker, Young, Jackson, Tull. That assessment recommended staying with Detroit. Dillon said the environmental department disagreed with the cost comparison and considered some operations capable of being performed more cheaply. The same news account preserves different descriptions of the promised saving. A Treasury spokesman's March 2013 email projected at least $100 million over twenty-five years, possibly $300 million. Task-force member Chris Kolb later described the deal as a financial wash, while another member, Eric Rothstein, questioned the premise of significant savings. Those figures and judgments have different owners. They are claims about the expected economics of the long-term deal, not a demonstrated saving realised by Flint after the crisis.

In March, Stephen Busch emailed the department's director and other staff with warnings about public-health risks associated with river water. These entries do not mean every recipient understood all the consequences that followed. F090, michigan.gov, Flint Water Advisory Task Force final report, March 2016
The city council's March 2013 vote was to join the new authority, not a vote specifically to drink river water while its pipeline was being built. The distinction became contested after the crisis. In January 2016, the Center for Michigan's Truth Squad, published by MLive, examined a state timeline that described the city as deciding to use the river. Earley later testified that the council vote was seven to one; Truth Squad assigned the interim decision to the emergency manager, not that vote. The new pipeline was not yet complete. A choice to buy water from it in the future left another question to be answered: what Flint would use until that water arrived. Conflating those decisions would move responsibility for the temporary source onto a vote that addressed a different arrangement.

Darnell Earley's later written testimony to Congress described the same council vote from the perspective of an emergency manager defending his role. He said the decision to purchase capacity from Karegnondi had been confirmed before he took office in October 2013. His predecessor, Edward Kurtz, signed it into effect on March 29, and Dillon authorised the move. Earley linked the arrangement to a water-system deficit of $8,758,091 as of June 2012 and to prospective cost reductions. The testimony is a participant's account, not an independent finding that all the choices were safe.

The task force's chronology gives dates for the same steps that differ from Earley's account. It places Dillon's email approving the Karegnondi arrangement on March 28, Kurtz's signed agreement on April 16 and Detroit's termination letter on April 17, so the March 29 signing date in Earley's testimony and the chronology's April 16 entry are two accounts with different owners, and this account does not choose between them. Earley's testimony also stated that a Kurtz order dated June 26, 2013 specifically contemplated operating the plant with river water for approximately two years before converting to the new lake supply, and the chronology records a June 26 engineering contract. Its dates nevertheless distinguish the capacity purchase from the later decision about the plant's interim operation. They do establish that water-quality concerns were in the departmental record before full-time operation began, and that the sequence involved several decisions rather than one council vote.

Detroit's letter ended the existing contract terms in April 2014, but it did not end all possibility of a negotiated supply. The task force says Detroit and Flint continued trying, unsuccessfully, to reach alternative terms during the final year of service. Both cities were then under emergency management and state control. Negotiations were continuing unsuccessfully when, in June 2013, the emergency manager authorized engineering services to put the Flint plant into operation using the Flint River as a primary source. A termination notice can sound like an unavoidable physical cutoff when read alone. Here, the task force's account expressly includes negotiations after the notice. The chronology therefore supports a narrower statement: the old terms were ending, negotiations did not produce a replacement agreement, and Flint proceeded with its own treatment plant while the pipeline remained unfinished.

Earley's March 7, 2014 letter to Detroit's water director said Flint was fully committed to using the river until Karegnondi was ready. In his later testimony, he said he reserved an interest in an interim contract if the local plant encountered substantial delay. He also characterised another full-time, long-term Detroit agreement as financially impossible after the money already put into Karegnondi. That is his explanation of the choice. His testimony described a January 2015 DWSD letter confirming estimates of reconnection costs, which came after the March 2014 letter, and said he never received an offer of discounted short-term rates. The letter and testimony show the direction in which his administration was proceeding and the financial reasoning he offered. They do not establish that the treatment and distribution system had passed every test needed for a safe change of source.

The final approach to operation brought a more immediate warning from inside the water utility. The task force records that Michael Glasgow emailed the environmental department on April 16 and 17, 2014 about the plant's unpreparedness and apparent political pressure to start distributing water. The warning concerned readiness before the switch, rather than a result from later regulatory sampling. It placed the immediate operating condition of the plant before the department while the start of distribution was approaching. The utility was moving towards continuous operation, and the staff message indicated that the condition of the plant and the pressure to begin were already in tension.

The public announcement was much more confident. MLive's report before the ceremony said residents could begin receiving river water on April 25. The city stated that the environmental department had given final authorisation to distribute water from the local plant. County, city and departmental officials were expected at the event. The article described the river as the primary source until the Karegnondi pipeline's expected completion in 2016. It also recorded a delay: officials had hoped to switch earlier in the week, but work on the disinfectant system still needed to be finished. Public authorisation and an anticipated ceremony thus appeared alongside evidence that preparatory work had continued close to the start date. The account says what officials planned and announced at that point, not what later testing would establish about water at individual taps.

At the plant on April 25, Mayor Dayne Walling pressed a small black button that changed a feed indicator from green to red. MLive described officials counting down, glasses of water raised beforehand and a group of about a dozen people inside the outbuilding. The mayor called it a return to the city's roots. The ceremony marked the end of almost fifty years of reliance on Detroit-supplied water, but the reporter also noted that officials expected about two days before the new water worked through the treatment system to residents' faucets. Exposure at homes was not instantaneous at that moment, and the ceremony did not measure the effect of the new water on the plumbing through which it would travel.

Environmental-department supervisor Steve Busch told the reporter that people should notice no difference and said the final bacteria test had passed that morning. Earley called the change the best choice for Flint going forward. Utilities director Daughtery Johnson described the river as different from its earlier, pre-Clean Water Act condition and said two years of plant improvements had been completed in nine months. He acknowledged that the new water would be harder, while saying customers should not notice a difference. These statements preserve the assurances offered at the start, with their owners attached. Passing a bacteria test was one stated condition for beginning service. It was a bacteria test, and the quoted passage does not mention lead.

The task force later identified the absent treatment at the centre of the lead problem. The environmental department had decided incorrectly that corrosion control was not required immediately and that Flint could first complete two six-month monitoring periods. Only afterwards would the department determine whether treatment was necessary. The new water's corrosiveness ultimately released lead from pipes and fixtures, according to the report. This was not a claim that the river itself supplied all the lead found at taps. It was a description of the water interacting with the distribution and household plumbing. The task force's account places the problem in how the treated river water interacted with the distribution system and household plumbing, not only in the treatment plant. F090, michigan.gov, Flint Water Advisory Task Force final report, March 2016
The legal setting was already in place. The task force's regulatory section describes the federal Safe Drinking Water Act, the environmental department's delegated enforcement role and the Lead and Copper Rule introduced in 1991. The rule sought to reduce lead and copper at consumers' taps through optimised corrosion control and periodic monitoring. It required public education when lead exceeded the action level at more than a tenth of sampled taps, with further measures under specified conditions. For large systems serving more than 50,000 people, optimised corrosion control was required, and treatment already installed had to be operated and maintained. This account uses those provisions as the regime the task force described for the period, not as a substitute for later amendments. The safety obligation concerned the water reaching people, not simply the act of turning on a plant. F090, michigan.gov, Flint Water Advisory Task Force final report, March 2016
Residents soon complained about smell, taste and appearance. The task force records those complaints before describing violations involving E. coli and disinfection by-products. The report's sequence matters: the public's experience of the changed supply did not wait for a later study of blood lead or for a court to decide responsibility. Different problems also called for different tests. Unpleasant water, a bacterial violation, a chemical by-product and lead released from plumbing were not interchangeable findings. The first complaints established that people were noticing a change in the water they used. They did not by themselves identify every cause, but neither did the absence of a settled explanation make the complaints evidence of no problem.
