Challenge for Flovac: Gold Coast Marina Vacuum Pump Station upgrade

About the entity

Flovac is the leading company in the vacuum sewerage industry in Spain. As an engineering firm specialized in the design and installation of vacuum sewerage systems, our goal is to introduce the Flovac technology in Spain and Latin America.
  • Challenge for Flovac: Gold Coast Marina Vacuum Pump Station upgrade

A great challenge for Flovac. Gold Coast Marine Precinct is a dedicated industrial zone in Coomera, on the Gold Coast of Queensland Australia. The precinct supports marine manufacturing, servicing, repairs and refits of recreational boats. It is one of the most advanced and respected marine industry cluster developments in the Southern Hemisphere. It is the only purpose built marine precinct in Australia.

Covering 250 hectares, it it is home to some of Australians most prestigious motor yacht builders and industry leaders.

It includes Riviera Australia a winner of Australian Maritime Industry Exporter of the year on multiple occasions.

The Boat Works – a boatyard, marina and superyacht facility

The Gold Coast City Marina & Shipyard has over 90 expert businesses looking after a wide range of clients. They have won numerous awards for their facilities

The Challenge

All of the wastewater within the facility is collected via a vacuum sewerage system. Over the years the facility has grown and the requirements of what a sewerage needs to do has changed. How to handle the larger superyachts for example. How to reduce energy costs. And how to ensure that all equipment was the latest technology and would reduce any risks of sewage entering the waterways.

The hardest part of the challenge for Flovac was to fit new vacuum pump station equipment into a very tight existing space. The upgrade needed to take place with minimal disruption to any of the businesses in the precinct.

As the Vacuum Pump Station is located outside of the precinct’s grounds it is operated and maintained by Gold Coast Council.

Power Saving and Efficiency

The goal set by Council was to reduce the vacuum pump cycle time from around 6 minutes to less than 3 minutes. This would give a 50% reduction in power usage throughout the day.

There was also a request to increase the discharged flow from the system by 15% by using exactly the same specified discharge pumps that were currently installed. We managed to increase their flow from 18 L/s to 21 L/s.

Flovac’s engineers worked on the problem creating 3D modeling of the station to ensure that the equipment would fit the space. Then the operations group went over the plans to make sure that the operability of the system would not be compromised.

In the months after commissioning there has been a clear improvement and lowering of energy costs. Vacuum pump run times have decreased from 17 hours per day and are now running for only 6.7 hours per day. They previously had been running 3 x 500 m3/hr pumps most of the day with huge energy costs.

Flovac confirmed once again that there is no challenge that can resist it.
