The Idaho Water Resource Board at its Sept. 12-13 meeting approved 23 aging infrastructure grants worth about $12.4 million.

The legislature in 2022 appropriated $75 million to the board for projects that address system sustainability, rehabilitate or improve aging infrastructure or support flood management.

Projects involving irrigation water storage, delivery, drainage or treatment are targeted. The competitive, scored grants can cover up to one-third of the costs.

The current round of funding, the fifth, went to “an excellent slate of projects,” Jo Ann Cole Hansen, who chairs the board’s finance committee, said in a news release. “The projects are well distributed across the state.”
