Stormwater Detention Tank Inspections

Stormwater Detention Tank Inspections

Many commercial properties in Greater Sydney and New South Wales have complex stormwater detention tanks that store rainwater and slowly release it into the drainage system to prevent flooding.

Local councils use these tanks to conserve water and direct it where it is needed, or to immediately discharge excess water into the stormwater drainage system.

Tank Inspections Melbourne by Raven Engineering Group has inspected OSD tanks for a variety of 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 can develop a tailored project plan to meet your needs.

How Often Should OSD Tanks be Inspected and Maintained?

While most OSD system maintenance is done annually, biannually, and after specific storms, there are other areas that need quarterly and five-yearly inspections, depending on their specific application. Most of our inspections can be done within one business day.

Effective water detention systems are essential for property and human safety. If overflow systems are not managed properly, catastrophic consequences can occur. Neglected OSD tank maintenance can also lead to blockages and contamination, so it is very important to have frequent, timely, and thorough inspections.

We recommend having blockage removal services done just before a low-rain event, as it is easier and more cost-effective to remove leaves and organic debris while they are still moderately wet.

Financial Losses from Disregarding OSD Tank Inspections

Failing to inspect OSD tanks regularly can have a significant financial impact on businesses. This is because businesses may need to purchase replacement components or entire tanks, and they may also experience downtime. This is true for both small residential-style units and large commercial stormwater systems.

In addition to the cost of repairs, businesses may also be liable for damage caused by flooding if their OSD tank is not properly maintained. This damage can be astronomical, especially if the tank fails due to deteriorated components.

How a Well-Maintained OSD System Should Function?

A comprehensive detention tank inspection by Tank Inspections Melbourne by Raven Engineering Group will ensure that your OSD remains functional and performs at its peak between inspections.

Extensively inspected onsite stormwater detention tanks can be effectively screened for problems before they develop into major repairs. This saves owners time, money, and hassle, and may even prevent a dangerous flood.

Remember that as an OSD owner, you are legally required to operate an OSD that can store storm runoff for up to 100 years of average annual rainfall. Failure to meet this requirement, or others, requires the most rigorous commercial inspections to be conducted every time.

A well-maintained OSD should:

Onsite Stormwater Detention Tanks (OSD) and Insect Control

Commercial onsite stormwater detention tanks are often breeding grounds for mosquitoes. This is why they must be designed to allow for fast and effective drainage, if necessary for decontamination.

Regular tank inspections and maintenance can help to prevent stagnation and reduce the risk of insect infestations, especially mosquitoes. A professional maintenance and operations plan, developed by Tank Inspections Melbourne by Raven Engineering Group experts, can eliminate mosquito breeding.

Important to Note – Caution

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

Neglected stormwater detention tanks can accumulate decomposing matter, such as decaying pests and bacteria. This can produce extremely toxic and potentially deadly gases that cannot be detected by untrained people.

Never attempt to open or enter a stormwater detention tank under any circumstances. Always use the correct equipment and have at least one other person present.
