Bill Information: H0895 – Data Center Water Use Restrictions Act 2026
Bill Summary
House Bill 895 creates a new section of Idaho Code (42-252) that prohibits data centers beginning construction on or after July 1, 2026 from using water for cooling as a consumptive use, unless that water is supplied through a municipal, water district, or water and sewer district system. The bill declares an emergency and takes effect July 1, 2026, applying immediately to any data center breaking ground on or after that date. The Legislature embedded formal findings into the bill declaring that data center water consumption conflicts with the local public interest, runs contrary to state water conservation goals, and will harm local economies in watersheds where the water originates but the data center is located elsewhere.
The practical effect is a two-track system: data centers that tap into existing municipal or district water infrastructure may proceed, while those seeking to appropriate water directly from Idaho’s natural sources for cooling cannot. This effectively channels large-scale data center development toward areas already served by established water utilities and away from rural or undeveloped watersheds. The Department of Water Resources director is directed to weigh the Legislature’s findings when evaluating new water appropriations or transfers of existing water rights for data centers.
Overall Assessment
House Bill 895 produces a balanced overall score of zero, reflecting meaningful but offsetting impacts across the evaluation metrics. The bill earns positive marks for protecting Idaho’s water resources and natural environment by preventing new data centers from directly appropriating state water for cooling, a significant conservation measure given that large data centers can consume millions of gallons annually. These protections benefit agricultural users, rural communities, and existing water rights holders in Idaho watersheds.
However, the bill also draws negative scores in areas where it imposes regulatory constraints. The bill restricts private property rights by limiting how data center developers and operators can use water resources on or near their properties, and it raises concerns about responsible governance by creating a hard regulatory prohibition rather than a flexible, case-by-case administrative framework. The remaining metrics are largely unaffected by this narrowly focused water-use restriction, resulting in a net score of zero that reflects the bill’s targeted but consequential trade-offs.
Rating Breakdown
ARTICLE I. Responsibility in Government (-1)
The bill expands the regulatory role of state government by creating a new statutory prohibition (Section 42-252) and directing the Department of Water Resources to apply specific legislative findings when evaluating water rights applications. Rather than allowing market forces or case-by-case administrative discretion to govern data center water use, the Legislature pre-determines the outcome by declaring data center water consumption contrary to the public interest, which represents an expansion of prescriptive government regulation over private business decisions.
ARTICLE II. Citizen Involvement in Government (0)
The bill addresses water resource management for a specific industry sector and creates no provisions affecting elections, voting, public comment processes, or citizen participation in government. It neither expands nor restricts how Idahoans engage with their government.
ARTICLE III. Education (0)
The bill contains no provisions related to schools, curriculum, educational funding, parental rights in education, or any other aspect of Idaho's education system. Its scope is limited entirely to water use regulation for data centers.
ARTICLE IV. Agriculture (0)
While the bill protects water supplies that Idaho agriculture depends on by blocking a new class of high-volume consumptive users, it does not directly modify water rights for farmers or ranchers, alter agricultural water allocations, or change any laws governing farm and ranch operations. The indirect benefit to agricultural water security is real but the bill takes no direct action on agricultural policy.
ARTICLE V. Water (1)
The bill directly defends Idaho's water supply by prohibiting data centers from making consumptive withdrawals from the state's natural water sources for cooling. The legislative findings in Section 1 explicitly invoke Idaho's prior appropriation framework, declaring data center water use contrary to conservation goals and harmful to watershed economies, which reinforces state sovereignty over water allocation. By channeling data center water demand through existing municipal systems rather than new direct appropriations, the bill protects available water for senior rights holders and future beneficial uses.
ARTICLE VI. Natural Resources and Environment (1)
By preventing large-scale consumptive withdrawals from Idaho's natural water sources for data center cooling, the bill protects stream flows, aquifer levels, and the ecosystems that depend on them. The legislative findings in Section 1 frame data center water use as contrary to conservation and harmful to local watershed economies, establishing a protective policy posture toward natural water resources. One analytical perspective notes tension with minimal-regulation principles, but the dominant view is that preventing a new category of high-volume industrial water extraction preserves natural resources for multiple existing uses.
ARTICLE VII. Energy (0)
Although data centers are significant energy consumers, this bill addresses only water use for cooling and makes no changes to energy policy, electricity rates, hydroelectric operations, or energy independence. The bill's restrictions on data center water use could indirectly affect where energy-intensive facilities locate, but the bill itself contains no energy provisions.
ARTICLE VIII. Idaho National Laboratories (0)
The bill contains no provisions affecting the Idaho National Laboratory, nuclear research, technology transfer, or federal research facility operations. Its scope is limited to commercial data center water use.
ARTICLE IX. Private Property Rights (-1)
Section 42-252 creates a new state regulation that restricts how data center owners and developers may use water on or for their properties, specifically prohibiting consumptive use of water for cooling unless supplied through a municipal or district system. This limits the development options available to property owners who have invested in or plan to build data center facilities, imposing a government restriction on how private parties may utilize a resource in connection with their property.
ARTICLE X. State and Federal Lands (0)
The bill does not address the ownership, management, transfer, or administration of state or federal lands. Its provisions are limited to water use regulation for a specific industry.
ARTICLE XI. Wildlife Management (0)
The bill contains no provisions related to fish and wildlife management, hunting, fishing licenses, predator control, or habitat management. While protecting stream flows could have incidental benefits for aquatic species, the bill makes no direct changes to wildlife policy.
ARTICLE XII. Economy (0)
Section 42-252 imposes a hard restriction on data centers — one of the fastest-growing sectors of the technology economy — by prohibiting direct water appropriation for cooling at any facility breaking ground after July 1, 2026. This constraint limits where data centers can locate in Idaho to areas already served by municipal water systems, potentially redirecting billions in capital investment and associated jobs to other states with fewer restrictions. The bill prioritizes water conservation over economic development in the technology sector.
ARTICLE XIII. Health and Welfare (0)
The bill contains no provisions affecting healthcare access, health insurance, medical decision-making, public health programs, or welfare services. Its scope is limited to industrial water use regulation.
ARTICLE XIV. American Family (0)
The bill contains no provisions related to family structure, parental rights, marriage, right to life, or child welfare. It addresses water use regulation for commercial data centers exclusively.
ARTICLE XV. Older Americans (0)
The bill contains no provisions affecting older Idahoans, retirement security, senior healthcare, or services for aging populations. Its scope is limited to data center water use regulation.
ARTICLE XVI. Law and Order with Justice (0)
The bill contains no provisions related to criminal law, law enforcement, gun rights, sentencing, or the justice system. It creates a regulatory restriction on water use, not a criminal or civil justice measure.
ARTICLE XVII. National Defense - Securing the Border (0)
The bill contains no provisions related to national defense, military operations, veterans' services, immigration, or border security. Its scope is limited to state water resource management.
ARTICLE XVIII. Election of Judges and Idaho Supreme Court Justices (0)
The bill contains no provisions related to judicial selection, retention elections, or constitutional interpretation. It is a water resource regulation statute with no bearing on the judiciary.
ARTICLE XIX. Religious Liberty (0)
The bill contains no provisions affecting religious exercise, conscience protections, or government interference with religious institutions. Its scope is limited to industrial water use regulation for data centers.
