Urban Waste Water

The decentralized management of rain water with the hollow trenching system

By the decentralized infiltration of the rain effluent via infiltration surfaces covered with greenery the sewer system is relieved and, in case of strong precipitation, adjacent waters are less loaded with untreated mixed waste water. Apart from water protection the system serves for the flood reduction. Compared to the usual development of drainage systems costs can be saved, at least, however, the same level of costs can be achieved.
