Case Study: Water Pumping Station, UAE

24% reduction in energy usage

Handling around 60,000 cubicmetres of waste water a day, this municipal Water Pumping Station in the UAE was inefficient, expensive to operate and required a high level of maintenance to maintain process security.

The challenge

To find a more efficient pumping solution that would not only save money and secure the system, but would reduce the regular maintenance requirement.

The solution

Grundfos’ energy team were called in to carry out an Energy Check on the pumping system, which was based on two existing 500 kW pumps. They identified that replacing the old pumps with modern, highly efficient 450 kW Grundfos pumps would more than meet operational demand, whilst producing energy savings of 876,000 kWh/year – reducing overall energy demand by 24%. By matching pump performance to changing demand, the regulated pumps will extend pump life and significantly reduce maintenance requirements, particularly regular seal replacement, which had been a major issue with the old pumps.  The investment of AED 1,200,000 is producing estimated annual savings of AED 380,000 per year in energy costs alone, meaning the investment will pay back in a little over 3 years.  


Total energy savings of 876,000 kWh/year (24%); Reduced maintenance costs; more efficient system.
