Reno, Silicon Valley, and parts of the arid West have water-availability constraints that affect evaporative cooling designs. Lenders require explicit water rights documentation as a closing condition and may push toward closed-loop liquid cooling or hybrid air-evaporative designs that reduce water consumption.
Where water rights become a credit issue
Evaporative cooling consumes meaningful volumes of water, hundreds of thousands to millions of gallons per day for a hyperscale facility. In water-constrained Western markets, the local jurisdiction increasingly requires explicit water-use disclosures and may impose moratoria on large evaporative-cooling deployments.
Lenders treat water rights documentation as a closing condition in these markets and will not fund construction draws without resolved water-allocation paperwork. Sponsors targeting water-constrained markets typically design for closed-loop liquid cooling or hybrid systems that reduce evaporative water demand, which adds capex but de-risks the financing path.
