A hyperscale data center operator was constrained by water quality and cooling-water chemistry. High calcium, high alkalinity and a phosphate-based program held the system to only 3 cycles of concentration — driving water demand, sewer cost and an ESG / WUE position that blocked expansion into preferred locations.
A hyperscale data center operator was being blocked from expanding into preferred locations by its water consumption footprint. ESG targets and local water authority constraints required a materially lower Water Use Effectiveness (WUE) metric.
High-calcium, high-alkalinity makeup water combined with an existing phosphate-based cooling water program limited the system to only 3 cycles of concentration. This drove high makeup water demand, high blowdown volume, high sewer load, and a deteriorating WUE position.
The operator needed to improve WUE without any compromise to Tier 3 / Tier 4 availability — meaning all corrosion and deposition KPIs had to be maintained or improved through the program transition.
Conducted a 3-year review of water quality data, cooling tower operating logs, and operator and service provider records. Performed onsite evaluation and structured interviews with both operations and water treatment service teams.
Applied advanced saturation modeling and proprietary closed-loop particle-size prediction with failure forecasting — determining the maximum achievable cycles of concentration at the site's makeup water chemistry without compromising system integrity.
Redesigned the chemistry program: non-phosphate organic/polymeric chemistry, no inorganic corrosion inhibitors, automated chemical-feed resiliency mechanisms, and online monitoring for real-time verification — all corrosion and deposition KPIs maintained or improved.
