A sewage lifting unit basically consists of a collecting tank and a pump. The waste water flows to the collecting tank via a basic pipe and from there is lifted above the backwater level by the pump and transported further to the sewage system.
Such systems consist of a variety of a hydrophyte treatment plants for eco-hydrological regulation. They are structured in three zones: a zone for intensive sedimentation (in which a combination of fixed and portable structures modifies the hydrodynamics of the chamber and increases sedimentation); another zone for intensive biogeochemical processes (where thick limestone fractions capture phosphorus…
The measure is for waterproofing buildings against ground moisture and seepage water at below-ground structural elements like walls. There are horizontal or vertical sealing methods existing. Horizontal seals prevent that moisture rises up. Vertical seals prevent moisture to enter the building from the sides. There are several solutions available with bitumen (black tank) and with…
The measure resides in eliminating the risk of forest soil damage due to cutting. Specifically, the measure includes for example use of cable transport systems, caterpillar tractors, and avoidance of transport in the same routes. If damages of the forest soil occur, it is necessary to remediate them immediately in order not to disrupt the…
A proper hazard and risk assessment (with informative maps as central outputs) is the essential basis for starting an integrated risk management process. The assessment is a challenging multistep task, which requires – aside from clear objectives – input data (e.g. about historic events and damages, terrain and landuse data), methodological skills and decisions as…
Among other benefits, the measure serves as a heavy rain risk reduction measure as it delays and attenuates also water on its way to a stream. Wetland provides water retention and improves the hydrological regime of degraded land. Rewetting includes a wide variety of large and small-scale measures, e.g. impounding measures like blocking of drainage…
