SB848 establishes a Desalination Planning Task Force within the Department of Land and Natural Resources to study whether desalination can be a feasible large-scale source of potable water in Hawaii. The task force is directed to assess statewide water demand for housing, agriculture, and industrial uses; evaluate how desalination could supplement existing groundwater and surface water supplies; and consider whether it could help meet future water needs and improve resilience of the state’s water system.
The bill also requires the task force to examine how desalination could be incorporated into the Commission on Water Resource Management’s broader planning efforts and to develop findings and recommendations, including any proposed legislation, for the 2026 legislative session. The task force is temporary, must report by early 2026, and will sunset on June 30, 2026.
Impact
The bill does not directly authorize construction of desalination facilities or change water allocation rules; instead, it creates an advisory planning body to generate a feasibility study and policy recommendations. Its practical effect is to place desalination on the state’s formal planning agenda and to involve key state and county water officials, health and agriculture officials, and the Office of Hawaiian Affairs in evaluating future water supply options. It may influence future legislation, water management planning, and infrastructure decisions if the task force concludes desalination is viable.
Sentiment
The available voting history suggests generally favorable committee sentiment, with the Senate Water and Land Committee passing the measure 5-0 with amendments. The bill’s framing around water security, potable water supply, and resilience in light of the Red Hill contamination crisis indicates strong policy interest in exploring desalination as a backup or supplemental water source. No opposing testimony or recorded debate was provided, so the overall tone appears cautious but supportive of further study rather than immediate implementation.
Contention
The main areas of potential contention are environmental, cultural, and cost-related concerns. The bill specifically directs the task force to examine high energy consumption and brine disposal, which are common objections to desalination projects. It also requires consideration of impacts on historical sites, Native Hawaiian cultural sites and practices, and burial sites, signaling that land use and cultural preservation may be significant concerns. Another likely point of debate is whether desalination should be pursued as a major water strategy at all, versus continued investment in conservation, groundwater management, and other supply options.
