The difference is the tank has a sluggish release fitting on the side of the tank. This will be the upper level for the long-term storage. These fittings are generally put half way up the tank however can be put at various levels depend upon the volume of retention needed.
How Large Should the Tank Be?
The size of the retention or detention tank will depend upon the local council requirements and the size of the building’s roof location and hard surfaces. Most council’s who need storage and sluggish release of storm water supply standards on exactly what is needed for each website.
Storm galvanized water tanks can be created with fittings that help with both applications.
