Advanced for clean, low cost, reliable and sale water supply and treatment
CWS custom-engineers every new water treatment system to solve complex challenges and deliver performance beyond what customers thought achievable. CWS builds its systems around the problem—not what's in the catalog. And then offer to operate and maintain the system to guarantee the performance and equipment for up to 15 years.
We don't just exceed expectations. We expand what's expected.
Every system is engineered with exacting attention to technical, operational, and regional requirements.
We align our success with yours through shared risk, transparent economics, and guaranteed results.
We stand behind every system with measurable performance commitments and 15-year guarantees.
We hold ourselves to the highest standards because that's how we raise yours.
We solve complex problems by making systems work better together, not just side by side.
No hidden costs, supplier kickbacks, or penalties—just clear information and aligned incentives.
