Infiltration Tanks

Redeveloped Shopping Centre in Perth

Novaplas Group has been involved in many different projects requiring Stormwater Infiltration Tanks, from domestic soakwells to large commercial projects needing to control vast quantities of stormwater.

With a value of $85 million, a site footprint of 44,000m², multi-level car park and 10 residential apartments, a recently redeveloped Shopping Centre in Perth is now 65% larger with a total floor space of more than 37,000m². Larger roof and hardstand areas always add drainage issues to site developments.

Novaplas Group was honoured to be able to provide a solution in manufacturing and supplying Drainwell DW1592 Drainage Cells for this significant project. The Novaplas team worked within a tight  timeline and focused on delivering the goods enabling the Hydraulic Plumbing Sub-Contractor to complete their scope of works without delay.

More than 40,000 Drainwell cells were needed to manage over 5,730,000 litres of stormwater run-off from the site. The Drainwell Infiltration Tanks were installed below a 1,600 space, triple storey car parking structure. Thousands of vehicles visit the shopping centre every day.

One of the Drainwell Infiltration Tanks was installed directly below a truck loading dock. Many laden trucks park above this tank every hour to have their cargo unloaded.

A total of 19 Drainwell Infiltration Tanks were installed. Some of the tanks were up to 78m long and 6 cells high (2.54m).

The Drainwell system is manufactured by Novaplas Group, in Australia, utilising 100% recycled materials.

Drainwell stormwater modules are suitable for the following applications:

Rainwater Harvesting Tanks
Stormwater Detention Tanks
Stormwater Infiltration/Absorption Tanks
Bioretention
Rain Gardens
