Important Factors To Remember When Purchasing Stormwater Detention Tanks

With the increasing development of new suburbs throughout Australia, a lot of natural landscapes have now been replaced by concrete structures such as buildings, roads and pavements. Development and modernisation are essential, however, the fast and massive changes in natural settings have immensely increased the risks of flooding in certain areas. 

That's why the Australian Government has made stormwater detention tanks compulsory for all new and recently renovated constructions. So, if you are in the construction business, it’s essential that you understand the rules, standards and regulations of OSD (On-Site Detention) tanks.

An OSD tank is a temporary water storage tank used to control the flow of stormwater into the public stormwater system. An OSD tank temporarily holds the rainwater and then releases it to the public system through a controlled low diameter orifice. The run-off rate can be easily controlled, therefore avoiding the chances of flooding. 

The Government has recently made this compulsory for all new and recently renovated constructions. So, if your property connects to a public water system, then you must have an OSD tank installed. 

If you are in the construction sector, your OSD tank design must meet the guidelines mentioned in the Australian Rainfall and Run-off guidelines of 1987. The size and storage capacity often varies regarding the location. To get information about the storage size, you can contact the local council or your hydraulic engineer. 

The design must have all the required openings and must offer a controllable rate of discharge. You must submit your design and other documents and get approval from your local council before starting the construction process. The construction has to be done by a qualified professional. Once done, your OSD tank must be certified by a chartered structural and hydraulic engineer, by a statement confirming that your tank is built professionally and meets all the required guidelines.

It is essential to maintain the OSD tank in working condition. An OSD tank must be capable of storing all the run-off from a storm event of up to 100-year ARI to include the calculated SSR. Regular maintenance by professionals will make sure that your OSD tank is working well and meets all the required standards. The best part is that you can install the OSD tank above ground, underground or in combination based on your suitability.

And that's all you need to know about OCD tank installation. Always remember to contact quality service providers when installing a stormwater detention tank. 

On-site detention tanks greatly reduce the chances of flooding. So, your responsible actions while constructing your OCD tank can save thousands of human and animal lives. Contact an experienced professional and get an OSD tank built today.
