The program has allocated up to $10 million annually for grants to support water conservation efforts. Additionally, the USDA’s Natural Resources Conservation Service (NRCS) offers the Environmental Quality Incentives Program (EQIP), which provides financial assistance for conservation practices, including rainwater harvesting systems.

Non-Profit Organizations Supporting Rainwater Harvesting

The National Association of Rainwater Harvesting Organizations (NARHO) has compiled a list of non-profit organizations that offer grants and funding for rainwater harvesting projects. For example, the Rainwater Harvesting and Graywater Systems Grant Program, administered by the North Carolina Department of Environmental Quality, provides funding for projects that promote rainwater harvesting and graywater reuse. The program has allocated up to $100,000 annually for grants.

Tips for Securing Grants for Rainwater Harvesting Projects

To increase the chances of securing grants for a rainwater harvesting project, it’s essential to have a well-planned and well-researched proposal. This should include a detailed description of the project, including the water gutter system design, the expected water savings, and the anticipated benefits to the environment. Additionally, it’s crucial to have a clear budget and cost estimate, as well as a plan for maintaining and operating the system.
