Westfield Coomera

Platinum Hydraulic Design

The Challenge

Platinum Hydraulics were commissioned by Christopher Contracting Plumbing & Drainage to provide the hydraulic design for the Trade Waste Arrestor package for the new Westfield Coomera Shopping Centre precinct in South East Queensland.

Challenges with this particular site included deep invert levels which create significant hydrostatic pressures.

Due to the highly specified engineering of the Australian Tanks heavy duty anti-floatation designs, no further structural engineering for the application was required, therefore saving time and costs when compared to the original specified product.

The Arrestors for this site were pre-approved by Gold Coast City Council and consisted up to 16,000 Litres which allowed for multiple tenancy connections, as opposed to the costs involved in installing multiple units as originally specified on the development plans.

The Solution

Australian Tanks, having recently been added to the Gold Coast City Council list of approved treatment devices, proposed in conjunction with Platinum Hydraulics a solution built on its current range of Heavy Duty precast concrete tanks.

In effect, we were able to tick the boxes on all of the application parameters with the added bonus of offering more treatment capacity (up to 16kl) allowing for the multiple tenancy connections.
To ensure that all devices were compliant, Australian Tanks worked closely with Gold Coast City Council to acquire pre-approval prior to supply and installation.

Working as a team, Australian Tanks, the Contractor ‘Christopher Contracting Plumbing & Drainage’ and Platinum Hydraulics reviewed the original specification, calculated capacity requirements for each area, designed the individual tank capacities, then applied for the Gold Coast City Council approval.

The Results

  • Fully operational Trade Waste Package solutions provided within specified timeframe.
  • Fully compliant with all local council regulations.
  • Manufactured to Australian Standards AS5100.2, Anti-floatation, Trafficable by a fully loaded semi-trailer.
  • Delivered in time, and on budget.
