Preventing damage from storms and floods
Stormwater pump stations help protect areas by pumping away large volumes of water, thereby preventing the occurrence of flooding. Many cities and municipalities are located on or near bodies of water, creating a need for large, reliable pumping systems capable of handling large volumes of water. Others are located in flat land areas where natural water runoff is slow and difficult. Reliability is the main parameter when designing a stormwater installation.
Floodwater often contains solids and large amounts of fibrous materials, like branches, leaves, weeds, trash, dirt and sediments such as sand, silt, mud and soil. The pumps and pump station design face tough requirements, since trash must not get caught in the pumps or sediment in the pump sump. Inflow to the station will vary significantly between dry seasons and flood events. The most reliable pumps should be used together with a sound station design to ensure secure operation.
Understanding your challenges
- Stormwater often contains solids and large amounts of fibrous material
- Large inflows occur within a short period of time
- Operates for shorter periods over the year but when needed demands high operational reliability
- Good trash racks are a must
