WaReg protects the village from flooding
Backaryds Vattenverk backwashes its filters regularly. During this process, water is released into the village's sewage system at a rate of 16 l/s. The village's sewage system is designed to handle 5 l/s, so when they release water at a rate of 16 l/s, it becomes problematic for nearby homes. When the backwash occurs, homes in the area are affected by backflows in their basements. There are a few different methods to solve this problem. One method is to increase the pipe size to take into account the flow of water. However, this is an expensive solution for a village of about 400 people. A more efficient and less resource-intensive solution is to control the flow, dampen the excess and only release what the pipes can handle.
The solution
A WaReg flow regulator was installed to regulate the flow out of the waterworks. WaReg releases water at a maximum rate of 5 l/s, which is what the pipes can handle without being at risk of basement flooding. When the flow exceeds the 5 l/s rate, WaReg regulates the flow and the excess water is retained in a dampening pipe system. This allows the treatment plant to carry out its regular cleaning and gives homeowners in the area peace of mind, knowing that they will no longer be affected by basement flooding.
