Retention instead of flooding

If subsoil conditions are unfavourable to infiltration, the goal is to retain the stormwater and ensure a retarded, time-lagged discharge. Exposure to impulsive stress can thus be eliminated or reduced in sewer networks and waterbodies. To achieve this, systems with throttle outlets must be used. Retention trenches are a reasonably priced alternative to conventional retention channels or subsoil concrete tanks.

Plastic storage/infiltration systems are important components of stormwater management. They temporarily collect stormwater and discharge it later. Besides infiltration, the stormwater in the FRÄNKISCHE storage blocks can be used in various ways. With the RigoCollect watertight system, stormwater can be stored for stormwater harvesting, retention and storage.
