WATER
TS2 designed the project to keep water use low and to protect Southern Nevada’s water resources.
The data center would use an advanced closed‑loop air‑cooled cooling system that does not rely on evaporative cooling. This type of system is well suited for desert conditions because it does not spray, evaporate or release water.
​
The data center would use an advanced closed-loop air-cooled (dry) cooling system with direct-to-chip liquid cooling and dry coolers to eliminate potable water use and protect Southern Nevada water resources. The total anticipated water needed for this closed system is a one-time fill of approximately 480,000 gallons consisting of approximately 150,000 gallons for the loop that cools the chips through Cooling Distribution Units (CDU) and 330,000 gallons for chilled water loop.
It cannot use municipal or potable water because the cooling equipment is designed for the purified mixture only. After the initial fill, the system needs only small amounts of the same mixture—up to about 2,000 gallons per year—for routine maintenance. Any material removed during maintenance will be captured and disposed of offsite by licensed contractors.
​In comparison, Boulder City homes used more than 660 million gallons of potable water in 2025. The data center’s one‑time fill is about the same as three Boulder City homes use in a single year.
Daily water use at the facility would be limited to restrooms and a small kitchen, using about 1,000 to 2,000 gallons of potable water per day. This is similar to what any mid‑sized office building uses. About ninety percent of that water would be returned to the City’s wastewater system through a new sewer line that TS2 will design and fund in coordination with City staff.
During construction, TS2 will seek to purchase treated effluent from the City for temporary dust control. This would occur for six to ten months within the twelve ‑month construction period. The amount requested would be up to five hundred thousand gallons per day. This represents a small portion of the treated effluent the City releases into the surrounding desert each day, and the use ends once construction is complete.
​
TS2 is also committed to working with Boulder City and the Southern Nevada Water Authority to explore returning more than 1 million gallons of treated wastewater to Lake Mead each day. On top of that, TS2 plans to invest over $8 million in water and sewer upgrades that will strengthen local infrastructure.
TS2 is committed to using water responsibly and supporting southern Nevada’s long‑term water future.​

HOW THE AIR-COOLED CLOSED LOOP SYSTEM WORKS
​
A data center produces heat as equipment operates. The cooling system keeps temperatures stable so the facility can run reliably. Warm fluid moves through a sealed loop containing the purified water and propylene glycol mixture. Cooling units inside the building remove the heat, and the system carries that heat outdoors where it is released into the air without using water.
