The Rainwater Harvesting System has been changing the last few years. Mixed and separate sewer systems are discussed controversially, the EG water framework directive is strengthening the need for action.
The call for local solutions is getting louder. This also means to find suitable measures for the cleaning of burdened rainwater respectively surface water, not only in the ecological sense but also economically. The overgrown ground is a measure but not sufficient as a end-of-pipe solution or in very densely populated and sealed areas.
Our 3P Hydrosystem is able to clean rainwater of roof areas, parking sites, heavily contaminated traffic areas and metal roof areas in a way that the water complies with the normal regulations (LAWA, BBod SchV and partly even the critical value of the Drinking Water Ordinance).
