Bioretention system
Bioretention is a popular storm water management strategy often used in urban settings to combat the water quality and hydrological effects of storm water. This goal is achieved by selectively designing a system, which consists of appropriate vegetation (trees) planted in a soil medium, with a drainage system.

Wortelbunker
TreeTube is a perfect solution in combination with other underground utilities. The system is delivered ready to install on site. Excavate, place, close again.
Vario absorb system
Store water for the dry periods. Vario absorb captures water during rainstorms. All this under the rootable soil volume. The roots use this water during periods of drought.
Calculating infiltration crates
At HTW Treerootsystems you can order various infiltration crates from the IT Plus brand. The correct number of crates of a certain size that you should use depends on the number of square meters of paved surface and the amount of precipitation in millimeters that you have to store. You can then calculate the number of infiltration crates.
We show you an example of a calculation: Approximately 20 liters of rainwater fall per square meter of paved surface. If you have a paved surface of 100 m², you need a capacity of 100 m² x 20 liters = 2000 liters. You can then opt for packed crates of 200,600 and 1000 litres. Or you can put them together yourself and pack them with geotextiles.
