Chinderah Caltex
Wastewater treatment and management system on flood prone site at Chinderah Service Centre
PROJECT DETAILS
Location:
Chinderah NSW
Product
40kL K-HC-T STP
Capability
Design and Construct STP
Principal contractor, Hutchinson Builders, engaged True Water to provide a quality solution for the new northbound Chinderah Service Centre in Northern NSW. Several constraints including flooding, site access and available area were given high consideration. Therefore the sewage treatment plant needed to accommodate significant environmental factors. Design and planning for the project was conducted over 4 years.
Initially an area in excess of 6,000m2 was required for the wastewater management system. True Water worked closely with the developer and consultants to achieve a reduction in size of more than 60% due to our specialist disposal methods. This allowed the developer to maximise the footprint of development and achieve a higher yield. Importantly, the sewage treatment plant is located to ensure high amenity and aesthetic value.

The modular Kubota STP is lighweight, fibre reinforced and easy to manouvre.

The sealed gas tight lids are the only part of the sewage treatment plant that will be visible once installation is complete.
Part of any True Water installation is the careful finishing to ensure visual ammenity, particularly in areas that are viewable by the patrons of the business.
The blowers and control systems are housed in powder coated steel enclosures to withstand the elements.
The finished STP at Chinderah service centre is unobtrusive and finished to a high level.
Even though the sewage treatment plant is located next to the public car park, and within view of the service centre, most people would not even notice it is there.
A solution designed for unique service centre requirements
Commercial strength wastewater is high in greases and oils. This combined with 24 hour operation provided challenges to the sewage treatment plant and infrastructure operation. Similarly, a high fluctuation in flows during peak and off peak periods such as holidays, required robust hydraulic flow management.
The Kubota K-HC-T commercial sewage treatment plant was installed at the Caltex Service Centre to provide long term reliable treatment and onsite wastewater management. The K-HC-T uses biological processing to efficiently treat 40,000L per day of wastewater and uses gravity flow to minimise operational cost while maximising operational security. The K-HC-T includes internal buffer storage to safely manage peak flows without compromising treatment quality or producing odour.
The STP at Chinderah service centre is independent of the Council Wastewater Treatment Utility but still subject to government regulations. As part of our ongoing service, True Water have been working with stakeholders to ensure the system is always compliant and working at its best.
