Municipal Reclaimed Water
Treated municipal wastewater can provide a dependable non-potable source when additional treatment is aligned with cooling-system quality requirements.

Data Center Water Reclamation Systems
Create a dependable cooling-water supply from reclaimed sources near the point of demand, while reducing dependence on constrained potable systems.
01 / Campus Water Strategy
Treat Water as Infrastructure, Not a One-Way Utility.
Data center water planning is no longer limited to securing a larger potable connection. A resilient campus can combine reclaimed municipal water, internal blowdown recovery, storage, and modular treatment into a managed water system.
Hydrolus designs on-site or near-site reclamation infrastructure around the source water, cooling requirements, campus water balance, and local discharge rules. The objective is to keep suitable water in productive use for more cycles before it leaves the site.
02 / Water Sources
Build Resilience Across the Full Campus Water Cycle.
Cooling Tower Blowdown
Capture the concentrated stream removed from the cooling loop, treat target dissolved and site-specific constituents, and evaluate return to makeup water.
Compatible Campus Streams
Evaluate other non-potable or process-water streams based on chemistry, flow consistency, treatment compatibility, and the intended reuse point.
Integrated Water Balance
Connect source, treatment, storage, cooling demand, regeneration, and residual management in one site-specific operating plan.
03 / Project Development01 02 03 04
From Water Balance to Operating Utility.
A successful reuse project begins with the source and end-use requirements, then works backward into treatment, storage, redundancy, and delivery.
Map
Quantify source availability, cooling demand, seasonal variation, blowdown, storage, and current sewer discharge.
Test
Characterize representative source streams and define the finished-water specification for each intended reuse point.
Configure
Select pretreatment, synthetic mineral adsorption, polishing, parallel trains, controls, and residual handling.
Operate
Commission a modular water utility with monitoring, periodic regeneration, and a capacity plan for campus growth.
A More Resilient Campus Water System
Reduce reliance on potable water for cooling
Recover cooling tower blowdown for additional use
Create an alternative supply near demand
Scale treatment capacity with campus buildout
Support redundancy through parallel trains
Align source, treatment, reuse, and residual planning
Common Questions
Frequently Asked Questions
What water sources can a data center reclaim?
Potential sources include treated municipal wastewater, cooling tower blowdown, and compatible process or campus water streams. Every source requires testing, a defined end use, and a treatment design matched to local requirements.
Can reclaimed water be used for data center cooling?
Yes. Reclaimed water is already used for cooling applications. The treatment train must produce water that meets the cooling system's requirements for scaling, corrosion, biological control, suspended solids, and other operating parameters.
Where is a Hydrolus system installed?
Hydrolus systems are designed for on-campus or near-campus utility zones close to the point of demand. The final location depends on source-water access, storage, hydraulic routing, residual handling, redundancy, and site constraints.
How does modular capacity support campus growth?
Standardized treatment trains can be deployed in parallel and added as demand grows. Parallel architecture also allows regeneration or maintenance on one train while others remain available.
