You mean that the Emergency Manager of Flint and a bunch of State officials under Snyder rejected all offers to renew the water contract from Detroit (which was under its OWN emergency Manager at the time) which caused Detroit to give a one year termination notice. I don’t know how reasonable those offers were but Flint was being charged a premium because of its altitude and distance from Detroit.
So in a sense, this was two Snyder appointees fighting over their own bottom lines that led to Flint getting it drinking water from the Flint river (with the oversight and approval from other Snyder appointees).
And its not like elected officials from Detroit turned off the tap (so I don’t see where you get the idea that Detroit voted to turn off the tap on Flint). Flint could have continued to purchase water from Detroit but in an effort to save about $5 million during the period between when the contract with Detroit lapsed and the time when the new water supply came online, they decided to reject Detroit’s offer and treat water from Flint river as an interim measure. The Flint water treatment facility cost about $4 million. So as I understand it, they switched from Detroit water to barely treated water from the Flint river to save a million dollars.
