Stormwater Detention: Bunnings

Drainwell Drainage Cells Used At New Bunnings Warehouse project in Victoria

Drainwell Drainage Cells were the preferred option used for an On Site Storm Water Detention Tank (OSD) at a new Bunnings Warehouse project in Victoria.

The site required a 500m³ OSD tank to meet council requirements. The Drainwell OSD tank system footprint is 54m long x 8m wide. Storm Water flows into the tank and is then discharged into the council stormwater system at a reduced flow rate. The tank was installed underneath the busy car park area. Therefore, valuable land could be put to use.

A 95% Standard Proctor density compaction was achieved before the asphalt pavement layer was placed above the tank.

The Drainwell Drainage Cell Tank system is made in Australia from 100% recycled materials. Novaplas is the manufacturer of Drainwell Drainage Cells. Our Team is committed to providing sustainable solutions. We work with either Engineers or Contractors to effectively embrace Water Sensitive Urban Design requirements.
