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

waste water treatment system

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 the Ecofarmer 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.

Heavy Vehicle Wash Bay for Origin Energy

The RWTS heavy vehicle wash bay solution fuses traditional separation, with high end wastewater treatment facility with filtration componentry all supported within the Australian water sector.


Client: Origin Energy & Sodexo

Location: Reedy Creek lay down facility

Technology implemented: Heavy Vehicle Wash Bay

Industry: Energy



Remote Water Treatment Services were successfully awarded a design and construct project to action a suitable wash bay treatment facility that would see the wastewater treated for reuse purposes.

The RWTS system was no ‘off the shelf’ solution, that most other water treatment company’s retail to the market.

Over the past decade we have continually seen so many vehicle wash bay systems underperform in their duty to treat water to an acceptable reuse standard  leaving unsatisfactory and odorous water to wash and rinse whilst more importantly neglecting the impact on human contact.



The RWTS treatment process included an oversized hydraulic advanced beach pit and sump design separating the initial heavier solids portion – water was then transferred to the designated raw water tanks where pumps continually recirculated and aerated the fluid to prevent stagnant water minimising ordure and keeping particles in suspense  – batched through a Dissolved Air Flotation Process (DAF) with the correct chemistry applied –  treated water was then pumped through a dual set of glass packed media filtration units and then onto treated water storage – treated water was continually recirculated and monitored for turbidity, ph, conductivity and free available chlorine levels. Once the fluid was corrected and in specification it was then released to the hose reels and automated system to begin its cycle.

Although these sound like relatively simple filtration methods, the systems flexibility in design saw an impressive automation and control platform setting it apart from all other systems on the market today.

The heavy vehicle wash bay was programmed and controlled through our sophisticated Allen Bradley software platform with high end analytical instruments used as reference all programmed and calibrated by the RWTS electrical division.

All design work through to factory acceptance testing was completed in house at our RWTS Brisbane facility and completed by our team of professionals.


The result saw a bankable wastewater treatment solution offering clean water to the process upon every wash every time.

Engineered waste water treatment plant for the OZ minerals project

RWTS were successfully awarded the head contract to design and construct a suitable engineered waste water treatment plant for the OZ minerals project in Carapateena South Australia.


Client: OZ Minerals

Location: Carapateena South Australia

Technology implemented: EcoFarmer 250

Industry: Mining



The OZ minerals camp design life was for 20 years with a 450 peak manning accommodation and mine services administration facility attached. OZ Minerals required a waste water treatment plant solution to facilitate the accomodation water service needs. The Remote Water Treatment solutions experts designed the arrangement of a containerised Ecofarmer 250 platform. The modular sequence was required to be constructed to accomodate the wastewater for the project over the construction phase into permanent accommodation.



To achieve the project scope a centralised johnson wire screened raw sewage drew from the camp. Then screened fluid was transferred to the combined balance holding tank and the sequencing of the SBR trains allowed fluid to enter the biological treatment phase. Treated water chlorinated was dispersed on to the designated land application area. RWTS executed the project within the intended time line and meet all government approvals and certification. South Australia health requirements and submissions strictly state that all tankage must be structurally engineered and process certified. RWTS had the steel fabricated shells engineered and process reviewed certified by third party. RPEQ process engineering team, used sophisticated modelling software to achieve a suitable final effluent stream.



All equipment and hardware used on the project was of high standard and supported in the Australian markets giving RWTS clients the peace of mind that the equipment is built and deigned to the highest of standards.

Engineered water treatment system for the township of Linville: SEQWater

RWTS were subcontracted by SEQWater to design and manufacture a engineered water treatment system for the township of Linville. 


Client: Practical Engineering and SEQwater

Location: Linville municipal water treatment plant

Technology implemented: Engineered water treatment system for the township of Linville

Industry: Infrastructure



Due to the 2013 floods and changes in raw water from the Bores supplying the original Linville Water Treatment System, the Linville township potable quality of water could not be guaranteed. As a consequence of the environmental changes that were affecting the Linville township water quality the original water treatment system needed to be decommissioned. In the past seven years as an interim solution the potable water from Kilcoy Potable Water Treatment Plant was trucked in and pumped into the town reservoir which serviced the town requirements. This was not going to be sustainable in the long run and thus RWTS was engaged to provide a water treatment solution to meet the township long term needs and requirements.


Due to the non release site, a minimal waste water was being generated; which resulted in common back washable filter types not being a viable option.



RWTS partnered with Practical Engineering – a specialist project team who were given the opportunity to construct a purpose designed and engineered water treatment facility and compound. The Water treatment process required by SEQwater had strict specifications and needed to meet a specific virus and protozoa log reduction through various forms of treatment application and disinfection packages.

RWTS proposed a validated absolute replaceable cartridge filtration process with no backwashing requirement, validated Ultraviolet Disinfection System treatment and residual chlorine disinfection equipment. SEQwater process engineers agreed to the proposed process offered and the design was signed off as a viable solution for the township of Linville. RWTS was engaged and responsible for the turn key water treatment process, procurement, engineering, installation, commissioning and operator training hand over package to client.

Work commenced in late 2019 and was successfully completed in April 2020 after extensive performance testing was completed over a period of 6 weeks.


The Linville township was successfully supplied by RWTS with treated potable water via a custom designed turn-key potable water treatment system. The  water treatment system RWTS implemented provided a high quality potable water source conforming to the Australian Drinking Water Guidelines standards and strict guidelines outlined by the utility provider SEQwater.

Ultrafiltration System: Veolia Energy and University of the Sunshine Coast

RWTS were subcontracted by Veolia Energy to design and manufacture a ultrafiltration system (UF) for the University of the Sunshine Coast.


Client: Veolia Energy; University of the Sunshine Coast (USC)

Industry: Infrastructure – School and Universities

Systems: Ultrafiltration



The University of the Sunshine Coast (USC) is a leading tertiary education provider, catering to over 11,000 students on Queensland’s Sunshine Coast. USC prides themselves on their commitment of sustainability; with an active program to better manage waste, water and recycling. In an effort to minimise the use of potable water from the local council, USC engaged Veolia Energy to implement a ultrafiltration system (UF). RWTS were subcontracted to design and manufacture the water waste management system.

The water reclamation system treated water from the on-site holding dam to a potable standard. Furthermore the water was able to be used for cooling tower makeup (through evaporation) as part of the university’s air-conditioning system.


Due to site space limitations, RWTS was required to design the plant to operate effectively within a small footprint.


Industrial Ultrafiltration System

USC Water Reclamation System - Ultrafiltration

RWTS developed an ultrafiltration system (UF), with pre-filtration to purify the raw lake water. This removed all suspended solids and microbes to ensure high quality treated water.

The design flux of the UF system, RWTS needed to design the system to be capable of treating up to 10 kL of net permeate production. Advanced UF modelling software allowed RWTS to develop the basis of the water reclamation design, that was signed off by Veolia Energy engineers.

Due to the challenges with width restrictions within the plant room, tall, hollow-fibre ultrafiltration membranes were chosen for the design. This minimised the system’s lateral footprint through stand height membranes. The membranes were procured from our oversea supplier through many years of R&D.

The waste generated from the ultrafiltration (UF) system through chemical cleans and enhanced backwashes was captured into a waste holding tank. It then underwent a staged correction process with validation prior to the release to the council sewer network. This process was approved by the contractor and local plumbing council, meeting the strict trade waste guideline release limits.

The operating system took the form of an Allen Bradley PLC with HMI screen. Functional description (FD) was written and programmed by our in-house electrical division for approval by Veolia Water. The water reclamation system build saw RWTS use quality analytical and pumping components from trusted suppliers, including as Grundfos, Burkert and IFM.

The project was completed and handed over to client Veolia Water in June 2019. Both the University of the Sunshine Coast and RWTS were pleased with the delivered outcome and the system is currently being managed by Veolia Energy site operators.

Accommodation villages for workers in remote locations rely on a secure water source as their drinking water supply. In many instances, where water is transported in and stored, additional chemistry is required to maintain effective chlorine residual.

The RWTS water treatment plant has provided a turnkey means of disinfecting the water supply in the Bungaroo FIFO camp to allow for safe consumption. For added convenience, a state-of-the-art monitoring system has been integrated to allow for full remote telemetry communication with the plant operator. This provides the plant operator with the ability to consistently check on the status of the plant and tank level from the convenience of their office.

The RWTS containerised water treatment solution caters to the needs of small rigger camps through to large stay-over camps. Our systems include the highest quality analysers and pumping equipment to deliver effective pH correction and chlorine dosing.

Wastewater Storage vs. Onsite Treatment – How to decide which is right for your remote mining camp?

Are you curious as to whether it’s worth investing in onsite wastewater treatment for your project or simply storing wastewater before pumping offsite? We’ve been asked this question time and time again, so we’ve weighed up the pros and cons of each management method to help you decide.

Water management plays an integral role in the seamless day-to-day operations of any remote site, particularly an accommodation camp within the mining sector.

Water is an essential resource when it comes to:


  • cooking,
  • cleaning,
  • operating amenities such as showers, taps and toilets,
  • vehicle wash bays,
  • and most importantly, providing safe drinking water.

It’s no mystery then, that wastewater is an inevitable by-product of the extensive water usage on remote sites. In the early stages of planning any accommodation village, the pressing question of how this wastewater will be dealt with arises.

There are two primary options on the table:

1. Integrating an onsite sewage treatment plant

2. Storing wastewater for offsite treatment

There is no hard and fast rule when it comes to choosing which option is best suited to your site, but we’ve discussed a few key factors to consider. The table below very generally captures the best option based on these factors.


Water Storage vs. Water Treatment Matrix


How long is your site realistically going to be in operation?


A short-term site with a lifespan of just 1-8 months will likely see greater benefit in water storage.



  • Reduced capital investment – Any water treatment plant will likely not in operation for long enough to offset the greater investment of such a system.
  • Rapid deployment – Water storage options such as tanks or the WaterBox, offer the advantage of rapid deployment. These are pre-packaged products that can be transported to site on short notice.
  • Environmental approval takes time – A tailored wastewater treatment system requires environmental approval from the state’s environmental regulatory body in order to discharge effluent onsite. This is often a time-intensive process and, depending on the terrain of your site, may not be feasible for your site or project timeline.


If your site will be in operation for longer than 8-12 months, looking to an onsite wastewater treatment plant will likely be worth your while.



  • Pump-out fees will be too expensive – Although a more costly investment upfront, by integrating a wastewater treatment system you will be forgoing the costly pump-out fees of transporting your wastewater to an approved discharge location. This may be justified on a short-term project, but over time this will chew through the budget significantly.
  • Treated wastewater can be reused – Depending on your site, the treated wastewater can be used for local irrigation, reducing the demand on potable water.


2. Environmental Regulation

Environmental bodies have rigid regulations when it comes to discharging treated wastewater to the land. This can make the process of having a wastewater treatment plant approved a difficult endeavour, and even impossible when the terrain is not permissive of irrigation (e.g. close proximity to a bore, watercourse, wetland or spring).

Should your plans not comply with regulation, wastewater storage may be your only option.




Is your camp likely to be relocating on a regular basis? If so, a wastewater storage solution will be the better option. The WaterBox has been optimised for such circumstances and can be relocated with a 12-tonne forklift or crane. It’s shipping container design also lends it to easy compatibility with any truck/train transport.


Wastewater treatment systems tend to be far more difficult to relocate, and commission and decommission. Taking all other factors into consideration, these are far better suited to camps that will be in a fixed location for a prolonged period.

If you are looking for a turnkey wastewater treatment system that can move with your camp, discover the EcoFarmer.



Similar to the factor of time, the size of your remote camp will impact the volume of wastewater produced.


For a small camp consisting of up to 100 people, less wastewater will generally be produced and therefore, wastewater storage may be more feasible.


For a larger camp accommodating over 100 people, the volume of wastewater produced would likely be in excess of what mere storage could handle. This increased load would lend itself to a wastewater treatment solution being integrated.



At this point, you’ll understand that many factors will impact the cost of a wastewater management system, but generally:


  • for a short-term or mobile project, wastewater storage will be more cost-effective.
  • for a long-term, fixed project, onsite wastewater treatment will be more cost-effective.

Below we’ve outlined the primary costs (other than the cost of the system itself) associated with each option:

Wastewater Storage


  • Wastewater pump out – Only licensed liquid waste transport operators can legally transfer wastewater to an external facility. Due to the environmental, public health and workplace safety risks of transporting such high volumes of sewage, the cost of liquid waste removal services can be extremely high.

Wastewater Treatment System 


  • System maintenance – A wastewater treatment plant will require regular maintenance to ensure the ongoing efficiency of the system. Neglected plants with built up residue will eventually break down and require expensive repairs or replacement. We recommend a cleaning-in-place (CIP) system to ensure the long-term health of your plant.
  • Chemicals and consumables – In order to treat the wastewater, chemical dosing is generally required. Therefore, there is an ongoing cost of ensuring there is sufficient inventory to keep the system in operation.
