Services Provided
Worked with local city and state agencies to develop regulatory guidance for using reclaimed water for data center cooling tower makeup water Completed a reverse osmosis cost-benefit analysis that identified the potential for up to a 37% reduction in water use at a data center facility with a projected water demand of over 500,000 gallons per day Investigated water reuse from rooftop adiabatic cooling units for a potential water use reduction at a data center facility to further advance sustainability of the facility.

Phoenix, Arizona
Project Practice Areas
Water and Natural Resources
Type of Facility
Data Center Cooling Tower
Project Specifics
A data center client in Arizona wanted to address operational challenges with their onsite cooling towers and explore options for reducing water consumption at the facility to increase sustainability and satisfy increased water demand as a result of facility expansion.
Geosyntec Scope of Services
The client requested that Geosyntec assess the technical and regulatory feasibility of connecting the facility to a reclaimed water network. Geosyntec is currently working with city and state agencies to develop regulatory guidance for reclaimed water use in evaporative cooling systems, creating a legal pathway for reclaimed water use that is currently not permitted.
Geosyntec also evaluated alternative approaches for online conductivity monitoring and water reuse from rooftop adiabatic cooling units, which are projected to decrease facility water consumption by up to 8% (approximately 6 million gallons of water per year). Geosyntec also supported improvements to the facility’s reverse osmosis system operations for the cooling water supply and is currently assisting with operational challenges associated with the facility’s sand filters.
Notable Accomplishments
Additionally, Geosyntec completed a reverse osmosis evaluation to investigate the costs and benefits of reverse osmosis water treatment at facility water influent or blowdown locations. Our evaluation showed that reverse osmosis has the potential to reduce facility water consumption by as much as 37%, which could reduce annual costs significantly. Geosyntec is currently investigating permit requirements and progressing on the design of a reverse osmosis treatment system for the client, with system installation anticipated in 2026.
