The Gladstone Area Water Board (GAWB) own and operate the Sewage Treatment Plant (STP) at Lake Awoonga. When the existing system started to fail after 35 years of operation, GAWB undertook an extensive tender and assessment process. They investigated many different treatment solutions to find the best outcome for the project. Performance history, company background and operational practices were all taken into account. GAWB chose True Water Australia to design, manufacture and install the new treatment system. Ongoing operational management will also be provided by True Water.

Replacement of existing Sewage Treatment Plant for Water Utility

Lake Awoonga is located approximately 30 km south of Gladstone, Central Queensland. The STP currently services the Lake Awoonga Caravan Park, a workshop, 5 residential houses, a kiosk, and a toilet block at the picnic area located at the boat ramp. The land set aside for sewage treatment infrastructure is north-west of the caravan park in a restricted access area. Two designated land application areas are to the south of the treatment plant. Also included in the treatment cycle is a wet weather storage dam. The existing STP servicing the needs of the Lake Awoonga area had reached the end of its operational life. The system required significant attention and management to maintain treatment processes and had ongoing difficulty achieving compliant performance. Due to the increasing operational burden and the decline in compliant performance, GAWB required a replacement treatment system. The True Water Design & Consultancy team proposed a complete wastewater treatment solution. This involved installation of a new Kubota STP and reuse of the treated water via alternating irrigation to land application areas. Upgrading the existing wet weather storage was also included. GAWB selected True Water to provide the new infrastructure as they proposed the only solution that met all of the project conditions. In particular the site constraints, longevity, life cycle management and the potential future increase in demand requirements were all met.

Key Project Considerations for Lake Awoonga Sewage Treatment

The GAWB process involved the assessment of key elements of consultancy and regulatory approval by GHD Engineering Consultants. The system is required to manage daily maximum flows of 40kL. Hydraulic flows can vary significantly with seasonal influxes of visitors. Therefore, the STP must be capable of reliably managing and treating fluctuating flow volumes and varying quality. The tender design indicated an above ground containerised or similar rotating biological contactor packaged plant. True Water identified the Kubota treatment system would be capable of providing improved project outcomes. Operational security is vital for this project with the STP located near the main potable water source for the Gladstone Region. A 40kL Kubota sewage treatment plant provided the highest level of reliability and operational security, with minimal operational cost burden. The design also allows for future expansion of the treatment capacity with the ability to add additional modular units. The Lake Awoonga STP must conform to the GAWB and the Qld Department of Environment and Science operational expectations. It needs to be highly reliable, including contingency and safeguards to ensure continuity of service at all times. Particularly during peak usage and power outages. In accordance with the GAWB’s operational mandate, the infrastructure must not negatively impact the environment. This aligned well with True Water’s vision for all STP’s to provide a neutral or beneficial impact to the environment.

World leading technology provides the simplest solution

Kubota Corporation mass produce three series of onsite STP’s under ISO:14001 & ISO:9001 certification. The systems can be applied to various applications to provide certainty through proven operation and surety of manufacture. True Water's consultants consider the scale of the project, the strength of influent and the quality of treated water. The most suitable STP is selected and the size and scale of the plant is confirmed. A Moving Bed Biological Reactor (MBBR) type treatment plant was chosen as the best fit for the Awoonga Dam specification. The final design demonstrates a best practice outcome for a commercial sewage treatment plant. This means the system balances technical specification, operational performance and technology complexity to achieve compliance treatment performance. All while providing a long term, financially sustainable solution.

Both Gladstone Area Water Board and True Water have a keen eye for detail and we shared many core values with a focus on quality, performance and value for money. Looking back the design phase was a highlight, working with Gladstone Area Water Board we were able to identify major design challenges. We had long discussions  about the challenges relative to the site and within the concept design and spoke in detail about the best outcome. We then we focused on designing true benefits into the system. This happened in each part of the infrastructure, the pipelines, the pumpwells, the Sewage Treatment Plant, control system and irrigation system. In each part of the project we were able to maximise efficiency and limit management requirements. We also saved some serious money along the way which I know Gladstone Area Water Board was very happy about. James Mahoney, True Water Australia, Managing Director

Delivering a sewage treatment solution for Lake Awoonga

Kubota Corporation manufactured the MBBR STP in Japan. Global manufacturers produced all components (including controller, pumps and blowers) to Kubota Corporation's design specifications. Mass production, standardisation, and uniformity provide security of operation. This allows Kubota to provide a strong warranty covering the entirety of the STP. They also offer a Performance Guarantee covering operation and performance. True Water fabricate and assemble all additional components including STP controller, telemetry, airlines, transfer piping and pump sets. Completing these tasks in our workshop prior to dispatch to site minimises risks associated with onsite fabrication. Installing the STP below ground eliminates visual and odour impacts. This also minimises temperature fluctuations and reduces deterioration caused by exposure to weather. The Lake Awoonga STP project included multiple life cycle stages; infrastructure design, project delivery and infrastructure management. GAWB and True Water held weekly meetings to ensure the project remained on track with the project objectives satisfied during each stage of the process. A key challenge of an infrastructure project is the coordination of multiple disciplines, for a sewage infrastructure project that’s especially true. For instance, throughout the design and delivery stages, many specialties needed to be coordinated: mechanical engineering, electrical engineering, telecommunications, plumbing, specialist irrigation design, civil works and of course wastewater engineering expertise.

New treatment system operational at Lake Awoonga

The new sewage treatment plant at Lake Awoonga is now operational and producing excellent water quality results. As part of True Water's ongoing commitment to the project, the Works & Services group is conducting ongoing training on site in the maintenance and operation of the plant. An official opening held with industry and government representatives highlighted the quality of the project. This included guided tours of the main treatment compound and all of the supporting infrastructure.

"We have a responsibility to deliver high quality infrastructure to the people of Gladstone, and we have achieved that. With due diligence and after a careful selection process, we appointed the project to True Water Australia. Their partnership as the Australian distributor for Kubota products, combined with their team’s knowledge and expertise in delivering sustainable and effective installations meant they were the right fit for our project."

True Water Australia assessed every aspect of this property renovation with Todd Knaus.  From the property restrictions and the owners needs, to the best location for the home sewage treatment system. The Todd Knaus Constructions project was particularly challenging for a number of reasons. We were able to fulfil the requirements of the project due to our extensive experience in the waste water treatment industry, and the collective knowledge of our skilled staff. While completing the project our focus remained on maintaining the ambience and aesthetic of the property and completely concealing the wastewater system. This was all achieved within time and budget constraints. Liaising with the governing council, the architect, the foreman and the client,and coordinating with all other trades, our team worked alongside the existing construction to ensure a smooth project delivery.

Project Overview

The Charles property was undergoing a significant renovation. The core change would reduce the dwelling from seven to five bedrooms. Numerous infrastructure alterations were also required. True Water Australia were brought to the project to upgrade the existing septic and drainage system. This had to be achieved in alignment with added constraints of the build area of the site increasing and the already scheduled demands of the renovation.

Challenges with Todd Knaus Property Renovation 

The property covered 4,047m² with limited area available for the sewage treatment plant and the disposal of the treated waste water. As a five bedroom home generates a large wastewater load, a solution had to be designed that would be suitable for the property. Site constraints included heavy vegetation, steep slopes with numerous trees and limited access. The existing needs of the already established architectural construction team also had to be considered and most importantly the needs of the home owner after everything was complete. The work had to be undertaken within specific construction stages of the property. The design and construction of the home’s renovation were already well underway. True Water’s team needed to work within a very tight and established work site with limited access for machinery and without hindering other tradespeople or impacting completed works. This required ongoing negotiation with the foreman and architect to coordinate both the True Water Australia and architectural work teams. This resulted in the completion of the project within the client’s specific and challenging time frame and most importantly within the client's budget.

The True Water Solution

Utilising non-recreational areas of the property, a lightweight, compact treatment system was installed, prior to the commencement of external construction, allowing the architectural team to continue work without hindrance and without the need for a crane or large excavator. True Water Australia developed and designed the LAA specifically to align seamlessly with council constraints and requirements and deliver the very best aesthetic solution for the property. We used an advanced secondary treatment home sewage treatment plant to reduce total job costs. Beyond reducing the cost, the advanced treatment system provides other benefits beyond cost savings;

• It allowed reduction of the total size of the Land Application Area (the area used for the application of treated water to the property). Minimising the impact of the system.
• It is the safest option and reduces the chance of soil contamination, algae, slime and odour
• Advance water treatment protects people from disease and viruses and prevents possible infection or sickness.

The extensive experience of the True Water Australia team allowed us to view several options for the Land Application Area (LAA) requirements. Several disposal methods were considered, using detailed calculations and site investigation. The only method which delivered on safety, aesthetic, compliance and longevity was irrigation. Several calculation methods were used, including Byron Shire Council’s wastewater model. We concluded that other options would be large, expensive and reduce usable space on the property. Irrigation was installed along terraced areas saving space and money and maximising usable area. While True Water Australia supply and install many types of on-site wastewater treatment systems, our role is not finished there. Once the system is up and running, we coordinate all management & maintenance services to ensure the wastewater system performs to optimum levels over a long period of time.  

Conclusion

Despite the tricky location, numerous constraints of the project and the challenging council requirements, out team deisgned a solution that adds value to the property without compromise. A very high-quality result was achieved, with minimal site impact and high aesthetic value. True Water Australia installed an advanced treatment system that provided exceptional value and functionality. Importantly, it also maximised the useable outdoor area for the client.  All True Water systems are designed by our Domestic Consultancy team for longevity, to provide a solution that services the property for decades to come.  

Pleass Global in Fiji have installed a new sewage treatment system in conjunction with True Water. The Kubota sewage treatment plant was required to service a new water processing and bottling facility. Pleass Global Pty Ltd is Fiji’s leading bottled water supplier with brands including Aquasafe and VaiWai water. True Water was engaged to design and supply a wastewater management system for their new facility 30 minutes from Suva. In 2008, 420 acres of pristine lowland tropical rainforest was acquired by Pleass in Namosi, Viti Levu, Fiji. Pleass had, until then, been extracting it’s source water from this land under agreement with the land owner. That land, now known as Kila World, has a 300 acre residential subdivision called Kila Estates. The remaining 120 acres is the water catchment area and has the extraction wells for the company’s bottled waters. The company also has an organic farm and Kila Eco Adventure Park on the water source land. The project required the fast design and delivery of a 10kL Kubota HC-Z sewage treatment plant. The solution was required to suit the tropical climate and extreme environmental conditions. Coordination between multiple parties was required to make sure the international freight of all components was achieved without delay or disruption. True Water manufactured and delivered a complete plug and play wastewater management system well within the required timeline. Installation was coordinated to include the use of local labour and trades to ensure community benefits were maximised.

Designing a Sewage Treatment solution for Pleass

Pleass Global asked True Water to design and install a wastewater treatment plant for their new factory in Namosi, Fiji. The new facility was being built in the water catchment area that provides artesian water for Aquasafe and VaiWai. Clean and safe drinking water is an important consideration throughout all of Fiji. Therefore it was vital the wastewater treatment solution was of the highest quality available. Pleass Global Beverages Video Profiles  100% Natural Artesian Water from the pristine rainforest aquifer under Pleass Global's certified organic farm land in Namosi. A wastewater treatment plant was needed to manage wastewater generated from the new facility. The factory and associated offices employ full time staff on a 12 hour shift basis. The wastewater originating from toilets, showers, kitchen and washing facilities was estimated at 5,000 – 7,000 litres per day. Additionally, wastewater generated from the manufacturing and cleaning processes required treatment. The approximate volume to be managed is 10,000 litres per day. All wastewater would require treatment and disposal on site. A review of the cleaning agents being used took place. As a result, more environmentally sustainable products were recommended. The use of biodegradable and phosphate free cleaning products improves the treatment plant performance. As part of the consultation process, True Water proposed three different options for treating the wastewater generated on site. The client was able to choose the solution most suitable to their needs. Discussions were had on site regarding the ability to scale our solutions should the need arise. Additional packaged systems can be added in the future to increase capacity as it is needed.

The True Water Solution

Our Consultancy Team elected to place the wastewater treatment plant and disposal point to the East of the factory. This was due to the location of the water catchment within the property. The 3 phase power and a supply line from the factory was provided to the plant location by the client as part of the installation. True Water provided a complete plug and play wastewater management system that is suitable to the pristine rainforest location. The Kubota HC-Z advanced sewage treatment plant was assembled in our manufacturing facility in Australia. The packaged system and all relevant components were then freighted to the company for installation by local labour. This in turn maximised the community benefits and led to further education and training of staff on site. True Water's technicians provided onsite supervision as well as online and over the phone technical support throughout the installation phase. Once installation was complete, a True Water service technician completed commissioning and provided initial training. As part of an ongoing service agreement, our technicians regularly visit the Pleass factory in Fiji to inspect the sewage treatment system and undertake water quality testing.

True Water were recently engaged to complete a full Sewage Treatment Plant (STP) replacement at Glencore's Rolleston Mine Accommodation Village. It is located in the southern part of Queensland's Bowen Basin, approximately 16 kilometres west of the Rolleston Township and 140 kilometres southeast of Emerald. More than 600 staff are currently employed at the mine which extracts coal for the domestic and export markets. The Accommodation Village provides housing and facilities for the mine staff.

The Project - Mine Sewage Treatment Plant Replacement

The Rolleston mine is located in a remote area far from municipal wastewater treatment infrastructure. An on-site, reliable and high-quality sewage treatment plant is required to keep the mine and its various facilities running smoothly. True Water Australia had previously designed, manufactured, installed and commissioned a Kubota HCZ-50 sewage treatment plant to meet the needs of the Administration Complex for the Mine Infrastructure Area (MIA). With remote monitoring, onsite training of personnel and a servicing plan, the wastewater treatment system has been performing at a high standard and meeting all QLD Environmental Authority requirements for the site. True Water were engaged to design, install and commission a replacement Sewage Treatment Plant at the Rolleston Accommodation Village when the existing containerised sewage treatment system failed. A swift replacement of the existing system was required as the failed Pureplus Treatment Plant was not operating to specified treatment levels, posing health and environmental risks. The system being replaced was less than two years old. Although it had failed, there were components that were still in operational condition. It was important to retain and utilise as many existing wastewater treatment assets as possible in order to minimise the costs involved in rectification works. An assessment of site infrastructure was undertaken to evaluate the suitability of existing components to integrate into True Water’s Kubota Treatment System.

Rolleston Rehabilitation Works

From development of the mine through to today's operations, Rolleston Open Cut has demonstrated their commitment to compliance with State and National environmental standards. This includes progressive rehabilitation of mined lands.   In July 2018, Glencore received an official certification from the Queensland Government after rehabilitating 220 hectares of mined land 140km southeast of Emerald, Queensland, an area around six-and-a-half times the size of Disneyland. Rehabilitation at Rolleston Open Cut

The Solution for Glencore

“We’ve recently contracted True Water Australia to design, construct (through Kubota), supply and oversee both the installation and commissioning of a new Sewage Treatment Plant at Rolleston Coal for our 700 unit accommodation village." "During the tender process we found TWA’s technical knowledge, proven working STP systems elsewhere and compliance to government regulations to be far superior to other tenderers. This was proven through consistency in results, testing and reporting data supplied.” James Bernstein – Project Manager, Glencore, Rolleston Mine, QLD Glencore were looking for a STP replacement solution that would achieve quality and budget requirements, while also minimising operational costs throughout the infrastructure life cycle. It was vital that this included operation, maintenance and monitoring. As part of their ongoing commitment to compliance with State and National environmental standards, it was important the solution True Water provided was of the highest quality and reliability. Glencore’s process included engagement of third party consultants and industry experts to inspect STP’s True Water have in operation in similar applications. This determined the suitability of the Kubota STP for the Glencore Rolleston site. The primary project scope was to replace a relatively new system, with guaranteed STP reliability and continuity of operation being key considerations. The Rolleston mine has also received government approval to extend its mine life beyond 2040. This would create an average of 84 full-time jobs over 10 years and once completed about 1200 full-time jobs. This could potentially double the requirements of the Accommodation Village, so the Sewage Treatment Plant needed to include the potential to scale up in size to accommodate higher influent flow volumes.

Project Details

True Water designed and constructed a 100m³ Kubota K-HC-T Sewage Treatment Plant with the potential to expand the capacity of the system in stages. The Kubota Treatment Plant provides biological treatment through a Moving Bed Bioreactor. This is contained within a single treatment Train which includes no moving parts or pumps. A future upgrade would see the same system installed alongside the first stage and utilising shared infrastructure throughout (Controllers, Buffer storage tanks and Treated water storage). “The Kubota STP commissioned for the Glencore Rolleston accommodation site greatly reduces the Principal’s operational costs and maintenance whilst reliably treating wastewater with proven technology from a world leading manufacturer.” Karl Hansen – Commercial Manager, True Water Australia A key advantage of using the internationally renowned Kubota technology is they are manufactured under ISO and Internationals Standards accreditation for the treatment of wastewater. This provides uniformity and surety. Because the Treatment Plants are premanufactured, True Water can deliver large scale Kubota plants in a short period of time and include a Performance Guarantee. This ensures each treatment plant meets the specific requirements of the site and application while providing security to our client. The design and manufacture of the Kubota treatment plants focus on ease of management with a reduction of servicing frequency and operational needs. Once design was finalised, Kubota undertook manufacture of the K-HC-T Treatment Plant. The Treatment Plant was delivered to site approximately 14 weeks from the acceptance of the True Water/Kubota STP and placement of the order. Once the STP arrived onsite it was a simple process to install the tanks, make final connections and backfill around the system. A process that took only six days, from delivery to operation. The existing failed sand/media filters were removed with a portion of the existing infrastructure retained and re-purposed. By repurposing this infrastructure, True Water were able to significantly reduce the rectification costs. The assets that were proposed to be kept were inspected on site for suitability and structural integrity before being integrated into the new Kubota system. The existing pump well, controller and power supply were able to be retained. Suitable existing concrete tanks were modified and pipes realigned to allow for their integration.

The True Water/Kubota STP Solution

True Water is highly experienced in providing replacement solutions for failed or undersized commercial wastewater treatment plants with specific environmental considerations. We recently completed two system replacements on World Heritage listed Fraser Island as part of our wastewater treatment plant contract with the Queensland Government National Parks. Eurong Rangers Station Sewage Treatment Replacement Dundubara STP Rectification Works True Water chose a Kubota system for the Glencore Rolleston Accommodation Village that would provide efficient and cost-effective sewage treatment. The STP produces a high quality of treated water and a high level of nutrient reduction, ensuring exceptional environmental outcomes. During the design and planning phases, all parties took part in a high level of communication to ensure that project timelines were met and continuity of service was guaranteed. The professionalism and organisation within the Glencore and True Water teams ensured the project was delivered on time and on budget.  “It was a pleasure working with Glencore and we look forward to working with them well into the future to deliver successful and trouble-free operation of their new STP.” Karl Hansen – Commercial Manager, True Water Australia  “Their team are experts in all aspects of wastewater from pricing and design through to delivery and contract management. TWA have been extremely professional resulting in smooth sailing with all milestones met and delivered without issue or incident.” James Bernstein – Project Manager, Glencore, Rolleston Mine, QLD

Even in the simplest of installations demand significant planning and thought for the most beneficial and professional of outcomes. The Klenk Property was one such project that, on the surface, appeared incredibly straightforward but, with True Water Australia’s consummate assessment and attention to detail, numerous elements needed to be added to the install. True Water Australia’s solution to the project had to include sufficient drainage and treatment for the existing structure while taking into account the ability to also service a proposed future residence. Cost-effectiveness and a range of location options also proved to require significant forward planning. Fortunately, through True Water Australia’s unfaltering expertise and experience, an excellent result was achieved for a very happy client. The level open property at first presented minimal limitations, the treatment system needing only to service a shed on the expansive site. The future addition of a dwelling, however, meant that a higher volume of treatment would eventually be required, and the location of the proposed property and its recreational areas would also need to be taken into account, all while maintaining the most cost-effective solution. Solution The installation of an advanced secondary treatment system reduced the overall size of the disposal zone, allowing for greater utilisation of recreational areas. Several options for the location of the unit initially presented themselves but, after assessment and consideration, the final location saved the client considerably in connection costs. As with every project, True Water Australia ensured that both the client and relevant tradespeople, in this case, an electrician, were consulted at every stage of the project. This is absolutely essential so as to ensure the most cost-effective, practical and legally viable solution. Conclusion Although the Klenk Project was essentially a very standard installation, it showcases the lengths to which True Water Australia analyse every parameter of a project prior to commencement. The Klenk Project proved to be a resounding success through True Water Australia’s attention to detail, high-class workmanship and continual communication and liaison between contractors and the client. Combined with the high-quality product, its efficiency and cost-effectiveness and the financial efficiency of True Water Australia’s planning, work and solution, these factors resulted in an exceptionally happy client and a first-class outcome.

Baillies Lodges aims to set new benchmarks for premium experiential travel in a unique Australian style. Their resort, on Lord Howe Island sits on the western side of the Island with uninterrupted views of the Pacific Ocean, reef and mountains. The resort that caters for luxury holiday makers recently received a much needed upgrade to their wastewater system. Lord Howe Island is located 580km from mainland Australia posing logistical challenges for commercial infrastructure. The island is World Heritage listed and has many untouched environmentally sensitive areas. Seasonal occupancy rates see varying wastewater flows throughout the year. The sewage treatment plant upgrade required a robust solution capable of consistent treatment performance and without impact to the environment. True Water undertook the installation that saw a Kubota HC-50 Sewage Treatment Plant transported to site via the Island Trader. Irrigation was installed in conjunction with the Kubota sewage treatment plant to provide the resort with the highest quality sewage treatment system available while ensuring no impact to the World Heritage site’s views and its pristine environment.

Camp Lake Fire is a quiet and relaxing bush retreat located high on the southern shores of beautiful Lake Maroon, approximately 90 minutes from Brisbane and the Gold Coast. The retreat has recently undergone upgrades and improvements including the addition of an amenities block with True Water providing a sustainable and cost-effective sewage treatment solution to service campers and staff alike. With the retreat located close to Maroon Dam operational and performance compliance where key requirements for the sewage treatment plant. Varying flows throughout on and off-peak visitor seasons also required a solution that would effectively manage peak flows without impacting treatment quality. The 10m³ per day Kubota HC-Z sewage treatment system was chosen for its robust design, ground level finish, scalability, ease of install and its high-quality treatment process. It has been a popular choice for the tourism industry, mining industry and large-scale industrial projects throughout the world.

True Water was awarded a Design and Construct contract to provide a temporary wastewater treatment solution for the Australian Defence Force. The project forms part of the Army Aboriginal Community Assistance Programme (AACAP) which began in 1997 to assist indigenous communities by providing infrastructure including housing, essential services and health facilities. The project required a wastewater management system with capabilities for demobilisation while maintain high treatment quality objectives. This was further complicated with the addition of low to medium volumes of trade waste included within the influent wastewater. True Water was required to work closely with the Australian Defence Force, associated contractors and local trades to meet delivery and operational requirements. True Water manufactured and delivered a dual HCZ System with installation above ground to ensure future demobilisation posed no risk to people, the environment or the Infrastructure. Specification and coordination assistance was provided to ensure suitable pre-treatment technologies were included upstream of the Treatment Plant ensuring operational targets were met.

Moreton Bay Regional Council awarded True Water the contract for the design and construction of a wastewater management system after a thorough tender evaluation process. Toorbul caravan park is located within 100mof Pumistone passage, a sensitive waterway which flows directly into Moreton bay. A new wastewater management system was required when the existing system failed. Key challenges faced were sensitive wetlands and waterways within close proximity, aging infrastructure allowing stormwater ingress to the capture network, and limited available area for the treatment system True Water decommissioned the existing treatment plant and undertook remediation works for the capture network eliminating stormwater infiltration. A 20kL Kubota HCZ sewage treatment plant was delivered and installed with discharge via an engineered mound system. The application method reduced the area required for the wastewater management system and allowed for the implementation of environmental buffers and extensive revegetation within the available area and budget.

Owned and operated by the Australian Indigenous Land Corporation, Home Valley Station is one of the most remote outstations in Australia. With recent expansions to the resort sewage treatment requirements have increased. As a result, True Water were engaged to provide a scalable treatment solution to meet wastewater needs. Although the 800,000km² cattle station is isolated deep in the Kimberley and is 3hours from the nearest town of Kununurra, they can have up to 800visitors a day. Everyone using the Gibb River road is like to stop in at Home Valley and grab a meal or use the toilets, so the reliability of the Kubota plant is of key importance for the isolated site. To allow for the future, wastewater infrastructure was required to be scalable, allowing capital investment to match resort growth, and robust, ensuring a long operational life in harsh climatic conditions. Seasonal occupancy rates required the wastewater treatment system to be capable of managing highly variable flows while maintaining treatment performance. Stage 1 of the sewage treatment plant involved the design and installation of four commercial Kubota HC-Z Treatment Plant modules with a combined treatment capacity of 40m³ per day. The Treatment Plant was installed below ground to regulate temperature, improve visual amenity and eliminate any impacts the extreme climate may have on the infrastructure. Stage 2 included the addition of three Kubota HC-Z Treatment plant modules bringing the total daily treatment capacity to 70m³. “Having worked in a remote environment in the East Kimberley, it is essential to have reliable and efficient services, the Wastewater Management System installed by True Water Australia is a state of the art Kubota plant that not only allows piece of mind, it is very low maintenance and the most effective wastewater management system I have worked with over a 20year career in remote resorts around Australia. True Water Australia are a professional company offering the ultimate in customer service and customer support, they go over and above and have exceeded my expectations with each and every contact.” Lynn Stollery – General Manager, Home Valley Station, Gibb River Road, WA
