Thousands of commercial properties across Greater Sydney and New South Wales have complex stormwater detention tanks (OSD tanks) in operation. OSD tanks are designed to detain rainwater and release it slowly into the stormwater drainage system, to prevent flooding.
Local councils use OSD tanks to store and direct rainwater runoff, both to conserve water and to channel it where it is needed, such as into stormwater drains. This helps to prevent flooding in particular municipalities.
Tank Liners Sydney by Raven Engineering Group has carried out OSD tank inspections for a variety of applications, including commercial and industrial developments and subdivisions, public amenities, and road infrastructure drainage systems. We understand that each commercial site has unique requirements, and our team is experienced in devising the most suitable and appropriate project plan for you.

OSD tank maintenance is typically done once or twice a year, and after major storm events. However, some parts of the OSD system, such as the overflow system, need to be inspected more often, depending on how they are used. Most inspections can be done in one business day.
OSD tanks play an important role in protecting property and people from flooding. If they are not properly maintained, they can overflow and cause catastrophic damage. Blockages and contamination can also occur if OSD tanks are neglected, so it is important to inspect them regularly and thoroughly.
We recommend having the blockage removal service done just before a low-rain event, as it is easier and more cost-effective to remove leaves and organic debris when they are damp.
Regular professional inspections of commercial detention tanks are essential to avoid costly repairs and downtime, as well as the potential for catastrophic flooding.
Whether it’s a small residential-style unit or a full-service stormwater system for a manufacturer, all commercial detention tanks need to be inspected periodically. Failing to do so can lead to significant financial losses, both in terms of repair costs and lost productivity due to downtime.
In addition, a poorly maintained OSD tank can cause widespread damage in the event of a major flood. This damage can be astronomical, far outweighing the cost of regular inspections and maintenance.
A comprehensive detention tank inspection from Tank Liners Sydney by Raven Engineering Group will ensure that your OSD system remains functional and performs at its best between services.
Thoroughly inspecting on-site stormwater detention tanks can effectively detect problems before they require major repairs. This saves owners time, money, and hassle, and may even prevent a dangerous flooding event.
As a stormwater detention tank owner, you are legally obligated to operate an OSD that can store storm runoff for up to 100 years ARI (Average Recurrence Interval). Failure to meet this requirement, as well as others, necessitates the most stringent commercial inspections to be conducted each time.
Commercial onsite stormwater detention tanks are often breeding grounds for mosquitoes. Therefore, they must be designed to allow for quick and effective drainage when necessary for decontamination.
Regular inspections and maintenance of detention tanks can help prevent stagnation and reduce the risk of insect infestations, especially mosquitoes. A professional maintenance and operations plan, developed after an expert analysis by Tank Liners Sydney by Raven Engineering Group, can eliminate mosquito breeding.
OSD inspections are dangerous and should only be performed by licensed and experienced professionals.
Neglected OSD tanks can contain decomposing matter, which can emit toxic and deadly gases.
Never try to open or enter an OSD tank. Always use the correct equipment and have at least one standby observer.
If you think there is a problem with your OSD, call Tank Liners Sydney by Raven Engineering Group.
