Sec. 16-703. Cooling Systems and Water.

• A.Required Technology. All cooling systems, primary, secondary, and auxiliary, serving computing, electrical, power generation, or energy storage components shall be air-cooled, Closed-Loop non-evaporative, or immersion cooling systems. Open-loop, once-through, evaporative, adiabatic, hybrid, spray-assist, misting, and water-consumptive cooling are prohibited. No exception, seasonal use, or alternative-technology approval is available.
• B.Water Sources. Groundwater and surface water shall not be used for cooling. No private well shall supply cooling fluid or cooling-related water, and no private well for such purpose shall be permitted on the site. Sanitary and potable supply shall not be used for cooling in any capacity. Reclaimed wastewater delivered by a dedicated, independent line may serve as makeup or charge water for a Closed-Loop system, but shall not authorize any evaporative equipment or method
