For the first two years of the TRIF Program, the Water Sustainability Program received roughly $500,000 each year, with the majority of the funding supporting the four water centers and a joint outreach and education budget. In the third year, the funding increased, allowing for the establishment of the competitive grants program and a fellowship program as well as an expansion in the funding available to the four centers.
