Bill Summary · SB 400

Legislative bill overview

SB 400 mandates that data centers operating in Kansas implement closed-loop cooling systems to reduce water consumption. The bill addresses the substantial water demands of data center operations, which have grown significantly as cloud computing and artificial intelligence infrastructure expand across the state.

Why is this important

Data centers consume enormous quantities of water for cooling—often millions of gallons daily per facility. Kansas faces water scarcity concerns, particularly in regions dependent on the Ogallala Aquifer. This legislation directly addresses competition between industrial water use and agricultural/municipal needs in a water-stressed state.

Potential points of contention

  • Economic burden: Closed-loop cooling systems require substantial upfront capital investment and retrofitting costs, which data center operators may pass to consumers or use to justify relocating to states without such requirements
  • Technological feasibility: Closed-loop systems are energy-intensive and may not be practical for all data center types or climates; requiring them statewide could push facilities to neighboring states with fewer regulations
  • Competitiveness concerns: Tech companies considering Kansas expansion may choose competitor states instead, potentially affecting job creation and tax revenue in the region
  • Implementation timeline: The bill doesn't specify compliance deadlines or whether existing facilities face retrofit mandates, creating uncertainty for both regulators and industry
