During the switch, the residents of Flint would get their water from the Flint River.
The government-funded free water bottles for the residents to use during the process.
On April 6, Governor Rick Snyder announced the end of the free bottled water program.
The government will not send more water bottles to Flint, the supplies there now are the last ones.
The announcement came in response to many tests that declared the water quality improved and safe for use.
Some residents of Flint cannot afford high quantities of bottled water from stores.
Nestle previously donated water bottles right when the Flint water crisis began in April 2014 by sending 19,000 bottles to the city.
They again aided Flint by sending 1.5 million bottles of water to the community in 2016.
Many members of the Flint community still do not hold enough trust in the government to use the water from the tap.
Residents require more reassurance, such as the completion of fixed pipes and the end of construction on the water system.
