Westgold Wastewater Treatment Plant

Another pair of Ecofarmer 250 units on deck for one of our mining clients in Western Australia. Arranged in twin train Ecofarmer 250 design with a Class A advanced media polishing packaged to ensure we meet our clients site compliance.


Client: Westgold

Location: Western Australia

Project: Westgold Cue Village WWTP upgrade

Solution: Twin Train Eco250 units with class a polishing package

Industry: Mining



The current waste water treatment facility situated at Cue Village Westgold needed to be replaced due to age and premature wear on the steel structure.

RWWA was asked to submit a proposal to design and construct a suitable waste water treatment system that suited the site hydraulic and incoming biological nutrient demand that would meet the release criteria as specified by governing body.

The new sewage treatment plant (STP) is designed to provide ongoing reliable service and to minimise maintenance requirements, ensuring ease of operation whilst maintaining reliable effluent quality and daily production.

The site compliance targets are based on standard nutrient with Class A disinfection requiring less that 10 Ecoli per 100 ml of sample. Our Ecofamer SBR solution is packaged and delivered complete with our integral Class A glass media filtration system, that will further filter the supernatant from the sequencing batch reactors (SBR) to a higher class of final effluent, to release to ground.


Our glass media design is based on the ‘Drydan Glass,’ a validated and certified media product sold here in Australia. This is a highly refined crushed glass with excellent flux potential, allowing for full rejuvenation through a backwash and chemical clean process that extends to the filtration cycle, as oppose to conventional sand base media.


Our Class A media package is housed in a 20 ft high cube container beside our Ecofarmer treatment units. A dedicated feed pump on the VSD control, will continually recirculate the supernatant fluid over the glass media. Then the flow pace chlorine injection will sanitise the water keeping the media beds at optimal working order, whilst reducing fouling potential free residual oxidant. This will then be monitored and corrected for bacteriological control in the final effluent water body. Once the water has met specification within the chlorine contact residence time, a modulating valve will allow fluid to pass to the irrigation field.

As part of our advanced technology, a centralised Allen Bradley HMI and PLC will engage the operator allowing for full remote access, reducing any unnecessary call out fees.


The RWWA difference is our unique fabrication process of our engineered certified steel reactors that provide a generous 20 year chassis life guarantee. Our chassis are built from the ground up with 6 mm flat sheet formed and pressed for the walls giving the ultimate in rigidity and corrosion allowance. In addition, a suitable international or Jotun coating is applied to the internal and exterior of the box.

We are committed to providing the highest quality product and service to our customers.

Maca Atlas Iron Mining Project | Wastewater Treatment Plant

wastewater treatment plant wastewater treatment plant wastewater treatment plant

Atlas Iron awarded Maca a contract to carry out open pit mining services at the Corunna Downs iron project in the Pilbara region of Western Australia.

Client: Maca

Location: Pilbara region of Western Australia

Technology implemented: Ecofarmer 50 series wastewater treatment plant

Industry: Mining


Corunna Downs, which is 100 per cent owned by Atlas Iron, is 33 kilometres south of Marble Bar and close to the iron ore miner’s Mt Webber project. The mine is expected to annually produce four million tonnes of iron ore initially. The life of the mine is expected to be between five and six years, with potential for future expansion as the current ore reserve considers only the above-water table resource.

Remote Water Treatment Services have designed in their custom Ecofarmer fabricated engineered reactor a waste water treatment system to cater for mining administration areas, ideal for low flow scenarios.

Ecofarmer 50

The design known as the Ecofarmer 50 SBR caters for flows as low as 2,000 l – 10,000 l per day, an extremely versatile waste water treatment plant for the demand and environment.

The waste water treatment system takes it’s design and methodology from big brother theEcofarmer 250, with the main process pump and motors located in the plant room, no moving parts are internal of the reactor allowing for ease of servicing.

The Ecofarmer design offers a treatment process with carbon and alkalinity supplementation dosed through our grundfos dosing platform controlled through the human–machine interface (HMI) ensuring optimal nutrient balancing through low demand periods. The system program looks for the level within the balance chamber automatically adjusting the cyclic nature of the process to achieve the desired aeration/mixing cycles. Further to this we have offered in our base offering a uninterruptible power supply (UPS) and Ewon remote modem for remote access into the programmable logic controller (PLC) and Human–Machine Interface (HMI), we can update software remotely and assist site based operators with handling issues that may arise without a call out fee.



A waste water treatment system that caters for mining administration areas and met all council regulations and had a positive impact on the surrounding environment.

RWTS structurally engineered containerised plug and play Ecofarmer system was installed with in 5 days of mobilisation. The system is backed by RWTS remote dial in logging platform to allow our staff to maintain and record plant parameters from our Brisbane based office assisting our clients site operations.


If you are wanting a system that works all day every day with the ability of remote monitoring, please call one of our friendly engineering team today to discuss your treatment options.
