The Elko, Nevada city council voted unanimously on August 11 to approve a ten-year Water Rights Priority Agreement with Bar L Ranch, Inc., prioritizing the city's category B reclaimed water for golf course and ranch irrigation, as the Elko Daily Free Press reported. Wastewater Superintendent Scott Dancz said the city can shut off access if the water is used outside the agreed purposes. City Attorney David Stanton said the agreement binds any future owner if the ranch sells, while acknowledging it does not address what happens if a new owner later seeks to change the land use. The council acted after public concern that the effluent could otherwise end up cooling a data center.
Every water-conscious cooling design of the past five years points at the same place. Amazon committed to a wastewater recovery system and a dedicated pipeline for its Gilroy campus. Veolia supplies Amazon reclaimed water in Mississippi. The EPA's water reuse action plan names data center cooling directly. When a community asks about the draw, reclaimed effluent is the answer that lets an operator keep an evaporative tower and still say the campus never touches drinking water. Gilroy is the current example. Elko just demonstrated the failure mode in that plan: municipal effluent is a finite asset with existing claimants, and a council can contract it away in one meeting, before an operator has even filed.
Category B reclaimed water in Nevada carries defined allowable uses, and this agreement narrows them further by contract. An operator evaluating Elko today has three options left: potable municipal supply, which is politically finished before the first hearing; groundwater in a basin the Humboldt system already allocates; or reject to air. In northern Nevada air is genuinely workable, with a low design wet bulb and long economizer hours, but it costs fan and pump power and it raises annualized PUE against the evaporative baseline the pro formas were built on. The western draw is already measured in billions of gallons against a drought baseline, and Nevada is simultaneously litigating who pays for two gigawatts in Reno. The closed-loop math is the only version that survives both fights.
This is a small vote in a small city and it is the most instructive thing that happened in cooling this week. The industry's standard response to the water question has a ten-year expiry and a golf course ahead of it in the queue. Any operator whose siting model assumes reclaimed effluent will be available should go read the wastewater contracts in every town on its shortlist, this quarter, before somebody else's council meeting removes the option. The design that never needed the water does not have to read anything.
