WaterM, the smart solution for rainwater reuse.
Our Integrated 4-Step Approach
From diagnosis to ongoing support, we handle every aspect of your rainwater reuse system
Diagnosis & Feasibility
We audit your site, analyze collection surfaces, and quantify your potential water savings.
Custom System Design
Our engineers design an optimized solution with high-performance filters, large storage tanks (e.g., 300 m³), and smart pumps.
Installation & Commissioning
Our teams handle all civil engineering and equipment installation, followed by rigorous testing and staff training.
Monitoring & Performance
A real-time dashboard tracks water savings and system health, supported by our proactive maintenance service.
Water is a precious resource
What if your buildings had their own free and sustainable water source? WaterM transforms your surfaces (roofs, parking lots) into a source of ecological profit.
We design and deploy turnkey systems to collect, treat, and reuse rainwater for your non-potable needs (toilets, cleaning, irrigation, industrial processes).
