Drening reflue: sustainable sewage for homeowners

Drening reflueis a cost-effective and sustainable solution for wastewater management for homeowners. It is used for the efficient disposal of domestic wastewater through sub-irrigation, following primary treatment. This is an ideal solution for residential areas that are not connected to the sewage system. Also, it can be a good additional solution in the case of the inefficient capacity of the existing sewage system on the property. The solution is based onpercolation, also known as sub-irrigation. This approach imitates the natural processes based on the regular top-to-bottom distribution of wastewater, in the so-called percolation bed made of many layers of draining material. Thanks to its large infiltration surface, Drening guarantees a fast and uniform infiltration in the subsoil. Therefore, Drening is much more efficient than often used micro-perforated pipes, providing improved percolation purification results.

Geocell easily increases drainage areas

As water management and flooding resilience are more demanding, we recognized the need for a solution that easily and efficiently increases drained areas. For this reason we designedGeocell. It prevents surface accumulation of rainwater and flooding by turning parks, meadows, permeable pavements, parking lots, and other surfaces easily into draining areas and it is very easy to install. By increasing drained areas and lowering dependency on sewage systems every project becomes more resilient to water risks. Geocellprovides faster rainwater runoff and drainage on local level, creating a thin drainage layer under parking lots, outdoor sport facilities, and pavements. Its main advantages are: Shallow excavation 30 % of the depth needed for gravel layer, Easy and fast installation (one worker can install 100 m2 / per hour), Bidirectional water flow (vertical and horizontal) that provides, Reduction of surface runoff, High capacity 27.6 l / m2 of rainwater can be stored within Geocell grid, Faster and more effective disposal of water toward the canalization, Reduction of the vertical hydraulic forces under the paving, Mechanical resistance and stability grid is mechanically resistant, even under surfaces with heavy vehicles transit, Adjustability to any slope of terrain, Void ratio of 91 %, which provides higher accumulation rate during heavy rains than with commonly used gravel drainage layer.
