When building sites below the groundwater level, actions to lower the water level are unavoidable. In addition to selecting the right drainage process, the protection of our groundwater balance is playing an increasingly important role.
Temporary lowering of groundwater levels can also have serious consequences, such as the settlement of buildings or the drying up of wetlands and springs. In order to avoid such damage, it is advisable from an ecological and economic point of view to use clean infiltration systems for groundwater subsidence.
When groundwater is removed and discharged into surface waters or even into sewerage systems, it is permanently removed from the natural groundwater cycle.
We offer common methods for clean infiltration such as gravity infiltration wells, seep slits or drainage systems. However, especially in densely populated metropolitan areas, these technologies are often impractical or costly due to the space required.
With the patented hw-dsi® process, we have developed a particularly gentle method for clean filtration in order to keep the impact on the groundwater body as low as possible. Thanks to special drilling measurement technology, the nozzle suction filtration system (DSI) makes it possible to infiltrate leachate much faster, more efficiently and more effectively into the soil layers. In contrast to conventional infiltration methods, hw-dsi® requires only one expansion of the well of DN50 – DN100.
Practice with the nozzle suction filtration system has shown that less water has to be removed from the excavation pit and the infiltration works without adversely affecting the excavation pit and the sinking target.
With our branches, we are in service throughout Germany. Contact us and we will find your individual solution.
Our Services for your project
No construction project is like the other. Trust in over 60 years of experience in water management to be able to execute your construction project without delay or other adversities. In doing so, we examine not only the economic dimension, but also the effects of large-scale groundwater subsidence.
Reinfiltration systems can also be connected to water treatment plants. Innovative methods are used to feed the treated groundwater back into the aquifer with the same groundwater level outside the shafts.
Control the influence on the aquifer by means of EMSR technology when groundwater abstraction in combination with pure infiltration systems. This allows you not only to check important metrics such as level, water quantity or level display, but also to document these interventions right away.
