Detention/Retention Tanks

Onsite Stormwater Detention Systems (OSD) are different on every project. OSD tanks capture stormwater on your site and control the flow to the local council stormwater system. Using pits, tanks or surface depressions as storage devices to temporarily store stormwater prior to discharge ensures that the Council’s drainage system is not overwhelmed in major storms – essentially, stormwater management.

OSD and Detention Control Pits (DCP) have become necessary due to the increased density of developments and particularly the increase in hard surfaces such as paving, additions, carports and garages on existing dwellings. Onsite detention doesn’t decrease the amount of stormwater, it simply slows its flow during peak discharge to match the capacity of the existing drainage system.

Mascot Engineering has been providing advice and product for use in OSD systems since their inception and can help you with your project. Our range of pits, grates (boltdown), RH3030 maximesh trash screens and stainless steel orifice plates are the simple solution.

Below you’ll find links to some standard products including a silt arrestor and a Victorian specific Detention Tank that is stocked in our Melbourne warehouse. Contact 1300 885 295 or to discuss your OSD requirements and we can manufacture a system to suit your requirements.
