Flood control



Limiting the potential damage of coastal and inland flooding requires a pumps system that won’t fail when required. There’s a lot at stake – initially, protection of people, crops and livestock, and in the longer term preventing contamination, damage to infrastructure and the potential risk of famine.

Ensuring that flood events can be controlled often requires careful planning. The application of Computational Fluid Dynamics (CFD) simulations at the design phase enables a tailored solution utilising Grundfos pumps that can cope with the heavy demands of moving vast flows of surface or storm water at low head, for flood control, harbour management, and such like. The Grundfos ranges of axial and mixed-flow pumps are specifically designed for strength and heavy flows and can be installed dry or submerged.

Stormwater tanks
Stormwater tanks are an effective way of reducing peak flow and equalising flow rates from storm water runoffs in the sewer system. Placed strategically, stormwater tanks mean better utilisation of the existing sewer system, allow for intelligent management of storm water flows, and ultimately save on infrastructure investments. Stormwater tanks can be built to almost any size and shape. The inlet and outlet can be managed by gravity, by a pump system or a combination of both, depending on hydraulic conditions in the system.

Grundfos offers a range of pumping and control solutions as well as mixers and cleaning equipment that together ensure reliable and automatic operation of the stormwater tank. Once the hydraulic load is reduced and capacity is available, you can get wastewater moving again with perfect efficiency.

Grundfos has the pumps to cope with these heavy demands. The Grundfos ranges of SE/SL, S and KPL/KWM pumps are specifically designed for durable use with heavy flows and can be installed dry or submerged. The Grundfos range of level sensor accessories ensures that your pump system can control possible fluctuations in demand for performance. This ensures the optimum delivery of wastewater to and from the stormwater tank.

The Grundfos DW pumps are robust, portable submersible pumps with a vertical discharge port, designed to handle dewatering at construction sites, excavation sites, buildings drainage and similar applications where there is a need to pump raw water or/and at high pressure.

Efficient mixing and cleaning of equalisation tanks is essential to minimise operation costs and avoid odour problems. The Grundfos range of RainJets is especially designed for this purpose, offering a robust construction and easy service and maintenance. The RainJets can work either alone or together with the robust and durable AMD mixer.

Control and monitoring
Control and monitoring systems increase the potential for improving both efficiency and reliability. Grundfos supplies pump starters and external variable speed drives (Grundfos CUE), Dedicated Controls for easy control of pump functionalities, and internet-based supervision (Grundfos Remote Management) with an easy-to-use SCADA interface.

Grundfos monitoring and control systems include plug-and-play communication interfaces that work with 95% of the communication standards available on the market. A comprehensive range of sensor accessories – such as level, flow and temperature sensors – ensures that you have the data required for your pumps’ control system.

Grundfos can supply the specialist expertise to help meet your performance objectives, from the initial identification of needs, to the selection, installation, operation, and maintenance of the pumping solution. Grundfos commissioning agreements ensure correct installation and service agreements cover all eventualities, from routine maintenance to spare parts, for optimal operation.
