User Quote

“WaterGEMS and WaterCAD helped us evaluate the improvement proposals for the Olinda supply system, which will benefit over 250,000 inhabitants, workers, and visitors in the region. This is just one example of how valuable this capability can be for basic sanitation companies, as it helps to improve human living conditions. Bentley is a key contributor to this process.”
