Drainage and flood control: effective and forward-looking solutions
Municipal sewage, rainwater retention, drainage of excavations and flood control – there’s a large range of requirements for safely collecting and discharging water and protecting infrastructures. Wilo provides specific solutions characterised by both a high level of energy efficiency and robustness.
Innovative flood control measures reduce the risks for people and nature
Those in charge in towns and communities as well as consultants and plant engineers need to overcome ever greater challenges in pumping sewage, rainwater retention and protection from high water or floods. The same applies to the drainage of excavations. Wilo’s product portfolio for drainage, flood control, rainwater retention and excavation drainage includes sewage lifting units, drainage pumps, wastewater pumps and powerful faeces lifting units.
More protection and increased efficiency at the same time
Depending on the requirement, users and operators of our wastewater pumps can choose between wet and dry well installation. Our systems are characterised by high-efficiency hydraulics, large free ball passages and submersible motors (protection class IP68, thermal class F). This means the best energy efficiency and electricity cost savings with maximum efficiency and reliably long service life at the same time.
How to optimally equip your pumping station for flood control
Communities can rely on Wilo drainage pumps to provide security in the event of high water and floods. Our modern high water and drainage pumps provide maximum delivery rates and start up first time around, even after a prolonged period of downtime.
This means that you can transport large amounts of water over low delivery heads in a short period of time. In this way, you can transport rainwater via dikes or dams and provide optimum drainage, for example. As our systems are specifically designed to meet your requirements, you’ll be well prepared for fluctuating water quantities or flow rates (depending on the quantity of rainwater or water level, for example at high tide). As well as reliability and performance, you’ll also benefit from our systems’ high level of energy efficiency.
Design a modern rainwater retention system
Rainwater retention in so-called stormwater retention tanks (rainwater overflow basins) is becoming increasingly important as flood management continues to develop. Retention tanks or temporary storage tanks are used to temporarily store large amounts of rainwater for a short period of time so that it can be discharged into the downstream receiving watercourse (drainage channel) at a slower rate or reduced rate.
In this way, you can avoid peak loads in your sewer system and therefore localised flooding. An important requirement for using your tank effectively is that the solids contained in the water do not form deposits that impair the tank’s function over time.
Drainage of excavations
For contractors and responsible parties in the public sector, draining your excavation is vital for the success of your project. Water ingress on construction sites, in civil engineering or during excavation works can cause considerable delays to your work. In the worst-case scenario, construction work may come to a complete stop, incurring high follow-up costs. Continuous and reliable drainage is therefore an important precondition in order to guarantee that your project progresses according to schedule. Use Wilo’s submersible drainage pumps for excavation drainage. Our pump systems are characterised by their high level of reliability for continuous operation in abrasive fluids. This is achieved by using wear-resistant material combinations, active cooling for continuous operation (particularly in slurping operation) and an integrated protection function. The pumps can be used in a wide variety of applications and put into operation quickly thanks to their low weight and flexible discharge connection. As a result, our pumps keep your pits reliably dry and therefore ensure that your work runs smoothly.
