Grandfathered irrigation rights are primarily established to protect existing agricultural businesses. These rights allow farmers and agricultural producers to continue using water sources for irrigation that they have historically relied upon, even as laws and regulations regarding water use might change over time.

In areas where water scarcity is a concern, regulatory frameworks can evolve to allocate water more efficiently and sustainably. However, grandfathered rights provide a level of security to existing agricultural operations by ensuring they can depend on their historical water usage without being adversely affected by new regulations designed for other purposes.

This protective measure helps maintain the viability of agricultural businesses, which are often critical to local economies and food supply. Such rights do not create new water rights, limit water usage specifically in urban areas, or establish water rights for residential developments; instead, they preserve what has already been established, ensuring continuity for agricultural practices.
