Custom Made Detention/Retention Pits
The main function of the retention/detention pits is to restrain the flow of storm water into the storm water system, particularly during periods of heavy rain. A galvanized trash rack can be added to withhold debris from the storm water system. The detention/retention pit and the galvanized trash rack can be custom made to your design.
MC2 Multicell
The Multi-cell was developed at the Swinburne University of Technology in the early 1990s. The Multi-cell is a compact rectangular precast concrete unit divided into 5 cells by diaphragms. Each diaphragm has a rectangular orifice along the bottom edge. As shown flow enters the unit and is progressively throttled through each cell until the required amount of flow reduction is achieved at the outlet. The rectangular orifices are staggered to ensure that flows will circulate in each cell and keep debris and sediment suspended. The units have been designed to be blockage free and it is claimed that no regular maintenance is required
