Two Sanilac County communities are getting grants worth more than $3.1 million to upgrade their water systems.

The city of Croswell has been awarded $1,881,000 in Community Development Block Grant Infrastructure Capacity Enhancement dollars.

The city will match the grant with $209,000, for a total project cost of about $2.09 million for water well and filtration plant improvements.

The village of Deckerville has been awarded $1.26 million in grant dollars. It will match it with $140,000, for a total project cost of about $1.4 million.

“Improving and updating infrastructure is vital to the continued health and economic well-being of our smaller communities,” Michigan Economic Development Corporation CEO Jeff Mason said in a statement. “The Infrastructure Capacity Enhancement grants will allow these communities with the most immediate needs to begin work as soon as possible to make necessary improvements.”
