 Mt St John Wastewater Treatment Plant Clarifier Installation
EPCO Australia was awarded the contract for the installation of clarifier mechanisms for three 42m secondary clarifiers and one 16m thickener as part of the upgrade to the Townsville City Council Mt St John Wastewater Treatment Plant which will cater for 106,000 people. EPCO was subcontracted to Baulderstone Construction, the main contractor for the project.
Installation of the clarifiers was completed in December 2010. After suffering minor damage from Cyclone Yasi in February 2011 they were repaired and will be commissioned in June.
The completed plant will treat wastewater, improve the quality of effluent discharge, increase potential for water re-use and protect the Bohle River receiving environment and ultimately the Great Barrier Reef Marine Park. The upgraded plant will deliver significant community benefits through reduction of sewerage treatment infrastructure within residential areas and will provide for future growth of the Townsville region.
On completion the upgraded plant will be the second largest sewage treatment plant in the North Queensland region.

 Bird in Hand Wastewater Treatment Plant
For the Bird in Hand project EPCO designed and supplied the digester system which compromises sludge heating, sludge mixing with gas lances and a mobile gas holder roof. The mobile gas holder roof collects methane gas and uses it for heating the sludge via a boiler. The unique thing about this site is that we were not allowed to physically flare the waste gas and had to capture the excess that wasn't used for heating.
As there were concerns over the potential for bushfires in the area the system had to be designed so that the excess gas would be used to heat the water which would in turn go through a cooling radiator and circulate back through the digester system. The digester uses microorganisms to break down the biodegradable material in the treatment plant.
In this system the sludge comes to the digester tank on top of which is a mobile roof. The gas emitted by the digestion process builds up a pressure under the mobile roof so it can be moved to the water heating unit. The whole system is self-generating.

 Mabuiag Island Torres Strait Sewage Treatment Plant
EPCO Australia has recently completed the installation of a new Rotating Biological Contactor (RBC) type wastewater treatment plant for the Mabuiag Island community. The contract also included the provision of Certificate III training for the plant operators. The new plant is based on the very successful Masig Island and Darnley Island wastewater treatment plant designs undertaken by the company. This robust and reliable RBC process is intrinsically focussed on the reduction of nutrients from the process stream with particular attention to reducing the nitrate concentrations of the treated effluent being discharged to the inshore ocean environment.

Offshore Projects
 EPCO Australia has over 35 years experience in developing specialised solutions for clients both within Australia and overseas. Our export experience spans countries such as Oman in the Middle East, Papua New Guinea, Singapore, Hong Kong, Fiji and Malaysia.
There are many types of treatment systems available throughout the world. Where EPCO Australia differs from many others is the way in which we approach the problem and the vast range of equipment options we are able to offer our clients. Large-scale wastewater treatment works are often the best answer for major cities and EPCO can certainly be of assistance in that area. We have installed Digester Gas Mixing/Activated Sludge systems in Singapore and Sludge Aeration systems in Hong Kong for large-scale municipal works.
In remote and environmentally sensitive locations however, a more specialised approach is required. Over the years EPCO has developed a variety of packaged sewage treatment plants to suit these scenarios. These plants are specifically designed for containerised shipping and where necessary for helicopter haulage to site. This primarily relates to packaged sewage treatment plants for mining/oil field campsites, remote small communities or island tourist resorts.
The choice of treatment system depends on the community's needs, the effluent quality required, and the financial capacity of the client. Often in developing countries a staged development process is the most appropriate solution. Initially, secondary treatment may be installed with upgrades being added as demand and funds become available. In these situations it is important that the initial sewage treatment plant is designed and positioned to accommodate the later upgrades. Where possible, EPCO endeavours to use local indigenous labour during the site installation process. This is then followed up with plant operational training of these individuals, thus creating an opportunity within the community for ongoing employment in maintaining the system that they helped to build.
In remote environmentally sensitive areas with stringent effluent quality requirements, a more sophisticated system is required with tertiary treatment and chlorine or UV disinfection. In these cases a Rotating Biological Contactor system may be more appropriate.
EPCO Australia designs the equipment, supervises construction, undertakes or supervises installation at the site and carries out commissioning and training.
