OSD Modular Tank Stormwater Modules or on-site detention tanks, are now required for all new or recently renovated buildings or developments.Simply said, on-site stormwater detention is a method of properly controlling stormwater on your property. If you work in the construction sector, it's your responsibility to know not only how to use OSDs, but also how to keep them in good working order.

Rainwater can no longer gather due to advancements in construction and the consequent destruction of much of our natural landscapes. Hard surfaces, such as pavements, roofs, and site drainage, increase the amount and speed of stormwater run-off elsewhere. Of course, because of the high risk of flooding, this is a source of concern for land, business, and home owners.

On-site storm water detention means that the run-off rate and volume may be easily controlled to limit the risk of overflow by providing temporary storage for storm water run-off. While the needed storage capacity and discharge rate vary by region, you can consult your local council as well as your hydraulic engineer or contact us for further information.
