Hawaii Senate Bill SB2753

Introduced
1/23/26  

Caption

Relating To The Environment.

Impact

As stipulated in the bill, beginning July 1, 2027, all new or altered individual wastewater systems situated within 200 feet of a shoreline must have denitrification capabilities. Furthermore, systems located within 1,200 feet of a shoreline in counties with populations between 190,000 and 800,000 are also required to have this technology if they lie on highly porous soil. This amendment to Chapter 342D of the Hawaii Revised Statutes signifies a proactive approach towards safeguarding local water bodies by managing nutrient levels that could adversely affect marine ecosystems.

Summary

SB2753 aims to enhance the protection of Hawaii's nearshore waters by mandating that newly installed or modified individual wastewater systems located near shorelines or on highly porous soils incorporate denitrification capacity. This legislative move stems from the recognition that clean nearshore waters are essential for public health and ecosystem sustainability. Coral reefs, which play a crucial role in protecting shorelines and supporting local fisheries, can be significantly harmed by nitrogen pollution from conventional wastewater systems, particularly in areas with porous substrates that facilitate pollution leaching into the groundwater.

Contention

While proponents argue that this bill would contribute to environmental preservation and public health, it could also prompt discussions regarding the financial implications for homeowners and developers faced with the requirement to upgrade or install new wastewater systems. Critics may raise concerns about the cost of implementing denitrification technology, which could impact existing residents and businesses. However, supporters maintain that the long-term benefits of maintaining clean waters, including the health of fisheries and coral ecosystems, justify these costs and are essential for the sustainability of Hawaii's marine environment.
