The Idaho Water Resource Board (IWRB) was allocated $75,000,000 by the Idaho legislature in 2022 for grants to address water sustainability, improve aging water infrastructure, or support flood management. These grants are for new projects or phases aimed at repairing, maintaining, replacing, or improving infrastructure that supports irrigation water delivery, storage, drainage, treatment, and use of water for irrigation. Municipal drinking or wastewater systems are excluded. The process includes proposal submission, review, and IWRB approval. Applications are due by August 2, 2024.

Grant renewed every year.
