Stormwater Detention Tanks Melbourne
Melbourne stormwater detention tanks
Melbourne’s infamous “four seasons in one day” climate can quickly transform construction sites into floodplains. Our heavy-duty fibreglass detention tanks are designed to handle Victoria’s weather extremes, protecting your development from water damage when downpours strike. These innovative stormwater detention systems provide Victorian builders with a dependable solution that effectively combats flooding while delivering generations of reliable service.

heavy rainfall & runoff

15 Year Industry Warranty

Protect your Melbourne development
Detention tanks operate differently from standard water storage because they stay empty between rain events. Equipped with a specialised release valve that gradually disperses water, our tanks enable you to manage sudden downpours without overloading your site’s drainage. This controlled release approach works exceptionally well as a long-term anti-flooding solution for properties across Melbourne and Victoria.
Stormwater detention tanks frequently asked questions
What is the difference between a rainwater retention tank and a stormwater detention tank?
A rainwater retention tank stores rainwater for domestic use, while a stormwater detention tank holds stormwater temporarily for release into the drainage system.
Do I need a stormwater detention tank?
Whether you need one depends on factors like property size, local council regulations, and existing stormwater infrastructure. Many new properties, especially in areas with significant impervious surfaces, are required to install a stormwater detention tank as part of their development approval.
How do I determine the appropriate size for my stormwater detention tank?
Consider factors like property size, council requirements, and available space.
How do I maintain my stormwater detention tank?
Regular inspection and cleaning of the tank and associated components are important.

Well done in bringing this product to the market
Hi Rob. Just wanted to pass on how pleased I am with your tanks. You have bridged the gap with a product that addresses the problems with the light weight poly products and the heavy concrete tanks. You have a brilliant design that will not split or distort as the poly tanks do or delaminate in a corrosive or acidic environment that will destroy any concrete tank. They do not need any heavy lifting equipment to install or transport and have a riser system that can be adjusted to suit the ground level perfectly without the need to position the tank to suit this. A truly brilliant product that will give years of service. Well done in bringing this product to the market. Kind regards, Wayne

Phil Wilkinson Plumbing and Gas Fitters have been installing the septic tanks and tank riser and lids for around 10yrs
Phil Wilkinson Plumbing and Gas Fitters have been installing the septic tanks and tank riser and lids for around 10yrs. These products whether it’s 3,000 or 30,000 ltr tank you need or just the riser they can do it. The risers are fantastic, lightweight yet very strong, sturdy and well made, these can be installed at any depth. The unit is a once buy, you’ll never have to dig it up again and unlike the concrete alternative, is level with the ground and does not need 2 men to safely lift the lid. It’s a no- brainer get it done today!

The saddle and riser worked out perfectly
The saddle and riser worked out perfectly. Easy to put in place – a brilliant design in it’s simplicity. I’m very happy that I came across you online. The pump out boys (Alexandrina council) we’re seriously impressed too – I’m guessing they’re hoping a lot more people put them in place too (save their backs)!

Direct supply throughout Melbourne and regional Victoria
Our lightweight detention systems ship directly to your Melbourne project location. We can handle freight across Victoria, or you can arrange transport through your trusted partner. Far lighter than concrete yet stronger than plastic options, our systems offer Melbourne contractors a more efficient delivery solution than concrete alternatives, keeping your project on schedule.
Our stormwater detention systems rely only on basic crane equipment for positioning, avoiding complex installation procedures that can hold up Victorian developments. This straightforward approach helps Melbourne contractors minimise labour expenses and reliably hit project milestones.
