Underground Detention/Retention Tank (Attenuation)
A Detention Tank using Atlantis Matrix® Tank Modules is water flow control system, which is man-structured. Similar to an infiltration tank, these underground tanks are designed contain stormwater or wastewater for a limited time. However, instead of being spread into the surrounding soil bed, the water remains in the tank. It can then be pumped out via motorised pump, or structurally piped to flow into the sewer or council drainage. Alternatively, it may enter a discharge control pit.
Note: some local councils also require plastic liner to be laid out underneath the underground tank. If you are after the waterproof membrane and are in SE Queensland, we can provide local contacts that can supply this product.
Atlantis' unique product is a highly cost-effective and environmentally responsible alternative to concrete tanks. Thanks to their 85% recycled plastic materials and cohesive design, you can create a detention tank which is cheaper, lighter and stronger. Each tank comes flat packed in bundles of large and small plates for easy, compact transportation to your site. No cranes or lifting equipment required!
Installation takes only a few minutes for each tank and can be modified to suit your specific requirements by varying the number of internal plates and stacking modules on top of each other. With more than 95% void surface area, Matrix units can hold 950 litres of water per cubic metre of tank.
