A new solution at a water storage tank in the supply area of Aarhus Vand regulates the flow into the tank with a needle valve. It is a dynamic, low-noise solution, and the valve is fitted with a control system that provides all options of operation both manually and via network connection.
Water storage tanks ensure water for consumers
One of the plants in Aarhus Vand’s supply area has three storage tanks for clean water. The storage system ensures that enough water can be supplied to consumers – also in case of fluctuations in consumption.
At this plant, there are two tanks of stainless steel and one of concrete. Water is drawn from another area and into the three tanks from where it is discharged into the supply area.
Reduction of the flow into the water storage tanks
The water enters the system with high pressure, and valves regulate the flow into the tanks.
Previously, the flow into all three tanks was regulated with butterfly valves. This was extremely noisy, and excessive noise and vibrations resulted in a poor work environment, wear and tear, and a shorter service lifetime of the installations. When the installation regulating the water flow into the concrete tank needed repair, Aarhus Vand took the opportunity to find a new and better solution.
