Stormwater Detention Tank Inspections

Thousands of commercial properties in Greater Sydney and New South Wales use complex stormwater detention tanks (OSDs) to collect and store rainwater. OSD tanks are designed to release rainwater slowly into the council’s stormwater drains, which helps to prevent flooding.

Fire Tanks Sydney by Raven Tanks Australia offers OSD tank inspections for a variety of commercial applications, including commercial and industrial developments, subdivisions, public amenities, and road drainage systems. We understand that each commercial site has unique requirements, and our team of experienced professionals will develop a customized project plan for you.

How Often Should Stormwater Detention Tanks (OSDs) be Inspected and Maintained?

General maintenance of OSD systems is typically performed annually or bi-annually, and after major storm events. However, some components of the system, such as the overflow system, may require quarterly or five-yearly inspections, depending on their specific use. Most inspections can be completed within one business day.

Effective water detention solutions are essential for protecting both property and human life. Neglecting OSD tank maintenance can lead to blockages and contamination, and in extreme cases, overflow failures. To avoid these problems, it is important to have regular, timely, and thorough inspections performed.

We recommend scheduling blockage removal services just before a low-rain event. This is when it is easiest and most cost-effective to remove leaves and other organic debris from the system.

The Cost of Neglecting OSD Tank Inspections Can be Significant

Neglecting to have your OSD tank inspected regularly can lead to significant financial losses, from the cost of replacing components or entire tanks to the cost of downtime and repairs. This is true for all commercial detention tanks, regardless of size or use.

In addition to the cost of repairs, a poorly maintained OSD tank can cause major flooding if it fails. This can lead to astronomical financial losses, as flood damage can be extensive.

To avoid these financial losses, it is important to have your OSD tank inspected regularly by a professional.

A Well-Maintained OSD System Should Function as Designed to Effectively Detain and Release Stormwater Runoff

A comprehensive detention tank inspection from Fire Tanks Sydney by Raven Tanks Australia will ensure that your OSD tank is functioning properly and performing at its best between services.

By having your OSD tank inspected regularly, you can identify and address potential problems before they become major and expensive repairs. This can save you time, money, and hassle, and it may even prevent a dangerous flooding event.

As the owner of an OSD tank, you are legally obligated to ensure that your tank can store stormwater runoff from a 100-year ARI event. This is why it is important to have your tank inspected regularly by a qualified professional.

A well-maintained OSD should:

Control its own discharge rate.
An OSD tank should not be full or partially full for a long time after a heavy storm or rainstorm.
Make sure that the stormwater systems and units downstream of the OSD tank can handle the additional runoff.
An OSD tank should be kept clean and free of debris, sediment, and other foreign objects.

OSD Tanks & Insect Control

Commercial onsite stormwater detention tanks can be breeding grounds for mosquitoes. To prevent this, tanks must be designed to drain quickly and effectively. Regular inspections and maintenance can help prevent stagnation and reduce the risk of mosquito infestations.

A professional maintenance and operations plan can help eliminate mosquito breeding.

Important to Note – Caution

OSD inspections are dangerous and should only be performed by licensed and experienced professionals.

Neglected OSD tanks can contain decomposing matter that emits toxic and deadly gases. Never try to open or enter an OSD tank under any circumstances.

If you think there is a problem with your OSD tank, call Tank Inspections Sydney immediately.
