Smart Water for Smart AI

Cooling Is the Lifeblood of AI Data Centers and It Depends on Two Things: Power and Water

Smarter Cooling Starts with Smarter Water

WesTech’s modular, source-to-rack water systems optimize cooling performance, protect uptime, and accelerate time-to-operation for the world’s fastest-growing infrastructure.

  • Cooling system failures account for ~19% of data center outages. Many are linked to water, refrigerant, or air-handling issues, a risk that optimized water systems can directly reduce.
  • Over half of major outages cost $100 K +; nearly 1 in 5 exceed $1 M.
  • Typical correlation: 1 MW = 4 GPM of cooling water demand.

When Water and Power Work Together, Uptime Wins

AI data centers run hotter, denser, and faster than ever. But water planning still lags behind power and cooling design, creating inefficiencies, delays, and lost capacity.

WesTech closes that gap with proven water strategies that keep your cooling systems stable, compliant, and revenue-producing.

Cooling Reliance

Problem: Cooling drives performance, but only when the utilities feeding it are optimized.

Solution: WesTech delivers high-efficiency, stable water systems that improve tower chemistry, protect chillers, extend component life, and even boost cooling efficiency itself.

Outage Risk = Revenue Loss

Problem: Cooling-related issues can shut down operations, and more than half of those major outages cost over $100 K; nearly 1 in 5 exceed $1 M.

Solution: Our filtration and side-stream reuse systems reduce fouling and blowdown, preventing unplanned shutdowns and protecting uptime.

The Planning Gap

Problem: Water design often starts too late, after EPC engagement, limiting flexibility and system performance.

Solution: We partner early, before the RFP, to size, integrate, and standardize water systems that fast-track startup and commissioning.

Community Pressure

Problem: Public opposition has already stalled $64 B in U.S. data center projects.

Solution: We help data centers adopt low-intake, high-reuse systems that directly support local sustainability goals and enhance corporate stewardship. These proactive measures align with community expectations, easing the permitting process and strengthening relationships with regulators and residents.

Built for the AI Ramp-Up

AI growth is accelerating fast. Water demand for AI data centers is projected to grow 11x by 2028, and hyperscale campuses are already exceeding 300–750 MW. Bringing these sites online quickly requires modular water systems built for speed and scale.

WesTech shortens design, permitting, and commissioning timelines with industrial-grade, proven modular solutions engineered for mission-critical reliability.

Keeping up with that growth requires smarter integration between water and cooling systems.

WesTech helps AI data centers go live faster by shortening:

  • Design
  • Permitting
  • Commissioning
  • Installation

This acceleration comes from industrial-grade modular systems proven across power, petrochemical, and large-scale infrastructure and engineered to meet mission-critical reliability for AI operations.

With over 50 years of mission-critical project experience, WesTech understands what it takes to bring massive systems online reliably, safely, and ahead of schedule.

Optimize the Entire Cooling Loop

AI data centers don’t just need more water, they need water that works harder. As rack densities rise and cooling loads increase, water efficiency is becoming as critical as energy efficiency, now measured through Water Usage Effectiveness (WUE). The entire cooling loop must operate as a unified system to maintain uptime, protect equipment, and manage daily water demand.

WesTech partners with cooling and engineering teams to build optimized water strategies from source to waste stream – improving tower chemistry, reducing fouling, and recovering valuable water for reuse.

At 100 MW, cooling operations can require > 500,000 gallons of water per day. Optimizing reuse and filtration can reclaim tens of thousands daily, protecting uptime and public trust.

Modular, Scalable, and Ready Before the RFP

For five decades, WesTech has supported hundreds of large-scale projects across power, mining, and industrial sectors. Each project demands precision, reliability, and speed. That same experience now supports AI data centers, where every day of delay can cost millions in lost revenue.

Accelerate Time-to-Live

Modular designs built off-site streamline planning, fabrication, and commissioning, accelerating delivery while reducing labor and construction impact on local communities.

Scale Effortlessly

Modular configurations expand from 100 MW sites to campus scale without redesign.

Collaborate Seamlessly

Our systems integrate with cooling OEMs, power OEMs, and EPCs to maximize overall thermal efficiency.
