Botanical Garden of the University of Leipzig
The “Botanical Garden” project includes the new construction of the water and wetland biotopes as part of the decentralized drainage concept for the use and infiltration of the rainwater that accumulates on the roofs of the administration, glass and cultivation buildings.
The basic construction of the wetland biotopes, the construction of the bridge foundations and the connection of the watercourse coming from the Alpinum were completed on schedule.
We are looking forward to the overall completion.
Rainwater infiltration – apartment buildings + garden house in Leipzig
The drainage of all roof and traffic areas according to the sponge city principle via extensive roof greening and the construction of block and trough infiltration systems was completed on schedule.
The drained area (AE) is around 2,191 m². The fee savings associated with the construction of the retention facilities amount to approx. 2,200 EUR/year.
Rainwater infiltration – Apartment building in Leipzig
The fee savings achieved with the construction of a block infiltration system and the planned absorption capacity of a large-area green roof amount to around EUR 1,000/year for this apartment building.
The retention area of the block infiltration system is approx. 20 m³.
The rainwater temporarily stored there is available for garden irrigation, among other things.
Rainwater infiltration – town house in Leipzig
The drainage of this beautiful town house in Leipzig is carried out via retention through a gravel trench with a perforated distribution pipe. The upstream rainwater storage tank collects the rainwater for watering the garden.
The fee savings here amount to around EUR 300/year, plus the reduced drinking water costs for watering the garden.
Rainwater infiltration – Hansaschule Frankfurt (Oder)
In the meantime, the drainage of the school interior planned here was planned via a simple grass trough. Swale infiltration is the simplest and most cost-effective infiltration option. The technical requirements for this type of infiltration are open inlets, a surface soil capable of infiltration and a sufficient distance to the average highest groundwater level.
