Bill > SB513

This bill addresses water scarcity challenges for small farms in Hawaii by modifying existing gray water recycling regulations. The bill authorizes the Department of Health to allow counties to implement gray water recycling programs for small farms (less than ten square acres), with specific limitations on the types of crops that can be irrigated using gray water. Gray water, which is wastewater from sources like sinks, showers, and laundry, can now be used to irrigate non-edible vegetation, fodder, fiber, seed crops not consumed by humans, and timber or non-food-bearing trees. The legislature recognizes that previous regulations inadvertently hindered agricultural productivity and innovation by restricting gray water use. By expanding gray water usage for small farms, the bill aims to support agricultural sustainability and help farmers facing water scarcity challenges. All gray water usage must still conform to the state plumbing code to ensure public health and environmental safety.
