SA councils call for water ROIs

The assets are contained within a consortium of the City of Onkaparinga, the Adelaide Hills Council and the Rural City of Murray Bridge, with the ROI the first of a potential three-stage market testing process to determine the future of the assets.

The total assets on offer comprise 16 community wastewater management systems consisting of approximately 220 km of sewer mains servicing around 6,500 customers, five stormwater harvesting/alternative water schemes, and two community water management systems servicing about 160 customers.

Adelaide Equity Partners has been retained by the consortium to manage and execute the process at state, national and/or international levels and the assets are not part of SA’s main water storage and supply distribution network.

The process will move to a second stage in the event the ROI generates the relevant interest, before a third stage would see due diligence undertaken with preferred providers with a view to moving to final recommendations and commercial completion.

The consortium stresses that there is no guarantee of any future sale, change in ownership or management of the assets.

DCS manufactures more hydro vac success

Established in 1993, DCS Manufacturing has long been servicing the stormwater and sewer drain cleaning and vacuum recovery industry. With specialised systems underpinned by its extensive range of accessories and spare parts, DCS also holds a large inventory of support equipment that cover tasks from basic pipe cleaning through to tree root and concrete removal.

The company says it has entered an exciting new phase in its ongoing development as it broadens the horizons in the industry by offering products, services and technology that have never been seen before. With a passion for research and development, DCS says its philosophy is building long-term relationships with customers by delivering quality products, the right advice and the best outcomes.

The Extractor is a high-pressure jetting system with vacuum recovery.

Customer satisfaction guaranteed

Attesting to this philosophy of building long – term relationships is SureSearch Underground Services, a leading utility locating, mapping and asset protection service provider with operations all over Australia. Due to its recent expansions into Victoria and southeast Queensland, SureSearch required an additional combination jet and vacuum truck to add to its growing fleet.

SureSearch chose DCS’ Extractor, an Australian designed and manufactured system that complies with all Australian Standards and Compliance Regulations, after previous experience with the company and its machinery.

The Extractor is a high-pressure jetting system with vacuum recovery that offers an all-round solution to cleaning and maintenance of stormwater and sewer lines with its hydro – excavation capability. The machine is equipped with both remote and manual controls, has an 8,000 L debris collector body, a water capacity of 6,000 L and a hydro pump of 200 bar.

SureSearch prides itself on using the latest equipment to provide its customers with unprecedented results for safe excavation, construction and planning, saying the “DCS Extractor has been a fantastic, simple to use machine compared to others on the market”.

It has been used on multiple projects around Sydney for both jetting and non-destructive digging (NDD) while also venturing into the Snowy Mountains for stormwater culvert cleaning.

Now, SureSearch says it can provide all NDD and jetting requirements out of its Melbourne, Brisbane, Unanderra, Sydney and Central Coast depots, and DCS Manufacturing says it also offers both extensive spare parts back up and service support across the country.

Another customer, Tasmanian-based Nu-Jet, also recently purchased machinery from DCS Manufacturing to use on local council works throughout the state including service needs of TasWater.

Offering a full range of drainage and relining solutions, Nu-Jet says it is a local drain cleaning, plumbing, lining and CCTV specialist that can take on any residential or commercial requirements and will continue to do so using its Longo 5000 Combination Unit.

The Longo 5000 is a combination high velocity jetting system with vacuum recovery, encompassing a compact and versatile system featuring high velocity jetting and an industry leading vacuum recovery system.

Designed for the cleaning and maintenance of sewer and storm water lines along with vacuum removal of waste from wet walls, septic tanks, collection ponds and more, the Longo 5000 Combination Unit is simple in its operation, requires low maintenance for its upkeep and provides built-in safety features for the ultimate protection of both operator and system.

The machinery comes with remote and manual controls, a 5,300 L debris collector body, 2,500 L of water capacity and a hydro pump operating at 210 bars. Longo is a leading advanced engineering company with more than 10 years of experience in manufacturing vehicles for the environment, allowing it to gain leading positions in the European and global markets.

KAISER jets to the top in Australia

The company recognises the growing need for efficient, high-performance sewer cleaning vehicles and continues to lead the industry charge towards greater technologies.

On the world stage, the foundations for KAISER were set more than 100 years ago, with the same principles of professionalism, technological advancement and strong customer service continuing to permeate through the business in its Australian arm. On an international level, KAISER is a third-generation family company that has evolved into an industrial enterprise with manufacturing sites in six countries.

KAISER specialises in the design, engineering and manufacture of world class vacuum and jetting vehicles for water recycling, sewer, stormwater, hydraulic excavation, industrial and dry suction applications. The company also designs and manufacturers pumps, components and walking excavators for the global market.

KAISER CEO Markus Kaiser says it is the continuity of its innovative developments that creates the healthy global brand that exists today.

“We are aware of the fact that innovations – aimed at added value for the customer – are key to maintaining our technological edge and to extending our leadership position in the future,” he says.

“That is why KAISER invests in pioneering product strategies, customer proximity, a strong branding policy and, last but not least, a powerful corporate culture.”

KAISER has extensive industry experience throughout Europe and the rest of the world, with its technology and development department playing a key role within the business. Since 1957, the company has specialised in vehicle mounted pressure/vacuum and jetting equipment, as well as mobile walking excavators, and kept these as its primary focus.

Unlike other manufacturers in the industry, KAISER has a singular concentration on high performance sewer cleaning vehicles, allowing the company to dedicate all its technological innovation to the sector.

KAISER also attaches great importance to professional consulting and customer care, with customers able to rely on experienced and technically accomplished employees. Professionalism in direct customer contact takes top priority but, for KAISER, selling a product marks a beginning and not an end.

The company escorts and supports its customers through the entirety of its product experience so they can fully exploit the potential of its vehicles and achieve their own business goals.

Making an impact in Australia

KAISER has a strong history within Australia, having notably built one of the biggest recycling vehicles ever produced for the City of Brisbane in 1993. This unit featured seven driven axles, two pressure convertors (680 L/min at 200 bar), liquid ring pump (6,000 m3/hr or 3,530 cfm), double high-pressure hose and two auxiliary engines. The unit was affectionately known as the KAISER MegaCombi and helped begin the strong relationship that still exists between the company and Flexible Drainage, then known as Flexible Pipe Cleaning Tools, today.

At the start of 2020, KAISER made the decision to come to the Australian market to directly support its existing customers and build on its reputation. Unlike other suppliers, KAISER in Australia is part of the same entity as the international brand, rather than being a third-party intermediary business.

The new face of KAISER in Australia is National Area Manager Kristian Stamenkovic who has extensive experience in the vacuum truck industry including with a variety of customer-built light, medium and heavy vehicles and specialised capital equipment. Mr Stamenkovic has more than a decade of experience in consulting, designing and selling trucks and other specialist equipment, which, coupled with his extensive background in construction and demolition, gives KAISER a local representative that exemplifies the company’s global structure of customer focused support and technical knowledge.

The company is also continuing its more than 20-year relationship with National Environmental Equipment (NATEE), which provides after sales service and support for KAISER in Australia. Clients can contact NATEE for local service and maintenance support, the supply of spare parts and training throughout the country.

Undeniable quality

KAISER now supplies its world-leading vacuum recycling, combination, hydro vacuum and jetting units directly to the Australian market. One of its most popular vehicles in the region has been the class leading and versatile AquaStar, standing as the latest generation of KAISER’s sewer and drain cleaning and industrial disposal series that sets new standards in efficient sewer and drain cleaning and water recycling.

Its extremely versatile capabilities are thanks to a modern design and striking new features including a remote controlled centre dividing door, multiple jetting hose sizes and the combined hose boom, along with proven in-house designed and manufactured high-power components KDU water pump, KWP vacuum pump and Single Stage Water Recycling RotoMax System. This unit can operate in all sewer, stormwater, hydro excavation, pit cleaning and industrial disposal conditions, with a maximum jetting capacity of 500 L/min and a maximum water pressure of 200 bar.

The vacuum pump delivers a maximum air flow of up to 4,000 m3/h, while the combined jetting and suction hose boom can take a suction hose length of up to 20 m and with the flexibility of the boom – offering 300° swivel and telescoping functions as well as up and down movements – further expands the working range.

The ultramodern KAISERtronic control system has enabled further optimisation of the hydraulic drive and output-regulated pumps that only deliver the capacity required, making the entire KAISER Water Recycling range decidedly more fuel-efficient while still providing consistently high performance. Additionally, the integrated remote maintenance system and even simpler handling enhance the operational efficiency of the vehicles and facilitate maintenance.

KAISER is also offering the new generation of its ECO 3.0 range, which features increased freshwater volume with a simultaneous significant payload increase. The vehicle is equipped with standard features such as the RotoMax, KDU, KWP and KAISERtronic control system where all relevant operating statuses are visualised by modern graphics on the remote control and control panel, while jetting and vacuuming capacity can be set independently of one another.

The ECO 3.0 is reliable even in the toughest conditions and has continually proved its worth as one of the superior choices on the Australian market.

For flexibility, KAISER’s Elegance 2.0 uses triplex plunger pumps that are available for the high-pressure system and positive displacement blowers for the vacuum system, with the respective pumps located between the driver’s cab and the tank.

This is performed by means of the power take-off on the carrier vehicle or a separate intermediate gearbox. KAISER has just redesigned a new range of Elegance 2.0 units featuring 6×4 hydrovac, 8×4 hydrovac, 6×4 combination and 8×4 combination units specifically designed and engineered to meet Australia’s unique market and conditions.

KAISER currently has the AquaStar III 8×4 Water Recycling unit and CityCycler 6×2 Water Recycling unit available in Australia, while the ECO 3.0 8×4 Water Recycling unit, Elegance 2.0 6×4 Combination unit and Elegance 2.0 6×4 HydroVac are in production.

KAISER’s wide range of recycling, combination, hydrovac and jetting units are designed to meet the highest performance requirements with the flexibility to handle a wide range of applications. Vehicles can be adapted to suit each respective customer’s requirements and the KAISER team will continue to work with buyers after a purchase has been made to ensure a maximum performance guarantee.

KAISER prides itself on meeting each and every customer need, drawing on its six decades of vacuum and jetting equipment experience to fulfil any requirement.

Winching to a win for top supply services

Due to COVID-19, the Hire and Rental Industry Association Australia had to postpone its 2020 Company of the Year competition; however, Winch Hire Australia is set to return in 2021 as one of two finalists, nominated for its unmatched service offerings.

Winch Hire Australia offers a variety of specialised diesel and electric winches for the pulling of all different sized pipes and liners. Its hiring services are available across the country with rentals also available for projects in nearby countries such as Papua New Guinea and Fiji.

The right products for the job

Winch Hire Australia National Sales Manager Troy Moulder says the use of winches is mandatory for relining works as it would be impossible to complete projects safely and efficiently otherwise. Currently, the company’s most common winches used throughout the lining industry are the 3 t electric winches and the 4 t, 6 t and bigger 10 t diesel winches.

Mr Moulder says Winch Hire Australia is always looking at ways to improve methods of hauling, with more products expected to be supplied in the future as they are developed and manufactured.

“We have invested more than 24 years in the industry, continuously improving our equipment to the latest technology,” he says.

In addition to supply services, Winch Hire Australia also provides its customers with onsite assessment and evaluation through reliable, direct communication with its experienced staff.

A rear view of one of Winch Hire’s winches, which are available as diesel or electrical winches.

Building ‘go-to’ relationships

Mr Moulder says over the past 13 years, Winch Hire Australia has worked closely with Interflow on a wide variety of projects, which has allowed a great relationship to develop between the two teams.

“One particular project comes to mind where we supplied our 4 t ZAD WINCH to assist Interflow with the relining of a series of pipes at Southport Spit, Queensland,” he says.

“You could say we are the ‘go-to’ company when they require hauling equipment. Matt Power, Branch Manager of Winch Hire Australia, has built a standing relationship with the team at Interflow over the years; understanding their projects and the types of equipment that they require to get the job done safely, efficiently and on time.”

Winch Hire Australia also supplies many other companies with lifting or hauling equipment, having been involved in many major projects including the Clem Jones Tunnel in its base city, Brisbane.

“There is no project too big or too small for Winch Hire Australia,” says Mr Moulder.

The use of winches is mandatory for relining works as it would be impossible to complete projects safely and efficiently otherwise.

Local servicing at its KOR

KOR’s new facility is located in Cockburn Central in the heart of Perth’s industrial zone and is a convenient 20 minute drive from Perth CBD, where it will support the industry’s growth in a region where vacuum and hydro excavation technology has thrived in recent years.

KOR says supporting WA’s growth with the equipment the industry needs is pivotal to the success of the state. Partnering with high quality product suppliers from around the world, KOR has the latest range of parts and accessories from Cobra, Southland Tools, Uraca, Duebre and an exclusive supply of Cappellotto equipment all in stock.

With Perth being the world’s most isolated capital city, KOR Business Manager for WA, South Australia and the Northern Territory Peter Jones – who lives locally in WA and is also the AUSJET ADVCA Chair – says Melbourne and Sydney are much further away than many people realise.

“Because of the significant distance between Perth and the eastern seaboard, it is important that we provide our customers the level of service and availability of spare parts they need locally in WA to confidently operate Cappellotto equipment,” says Mr Jones.

Further to its growth in WA, KOR has also opened a new facility in Preston, in Western Sydney’s industrial belt, to support Australia’s largest city with a spare parts range, unit availability and onsite industry professionals to support the product in the field.

KOR says this strategy supports the expansion of Australian cities and the large-scale infrastructure projects that continue to encourage economic growth.

“Projects including the Paramatta light rail, Greater Western Sydney Airport, a new runway at Melbourne airport, freeway upgrades and expansions across our cities and level crossing removal projects are all examples of projects where Cappellotto units operate,” said the company.

With unit parts and accessories now available in WA, Victoria, NSW and Queensland, KOR’s national footprint continues to grow, giving national fleets flexibility and local businesses access to a world leading industry equipment brand, Cappellotto.

KOR says customers trust the company because of its investment in the product, its Australia-wide operations and its continued product innovations that encourage a safer, environmentally friendly and more productive future.

Prioritising health in a post-COVID climate

by Sophie Venz, Assistant Editor, Great Southern Press

Australia has committed to the Paris agreement with its climate change target being a reduction in national emissions by 26–28 per cent on 2005 levels by 2030. Through direct action policies that reduce emissions, increase energy productivity and improve the health of the environment, the Federal Government says the nation is on track to meet its 2030 target.

Trenchless technology tackles the target

Trenchless technology, when compared to open cut methods of excavation and construction, eliminates the need to remove and then replace large sections of material aboveground, saving a considerable amount of time, manpower and – most topical of all – energy.

The March edition of Trenchless Australasia featured a thorough look at how trenchless companies can drill down on their operational emissions, with the article discussing how companies that have not adjusted their operations to prioritise a cleaner future are often on the wrong end of public sentiment.

Because of such public pressure, major projects – such as the Metro Tunnel project in Melbourne, Victoria – are monitoring, managing and mitigating the emissions produced by construction works in accordance with international, Commonwealth and state-specific legislation, objectives and requirements.

However, these changes are not only being enforced by construction projects and their contractors.

Across the Australasian region, utilities, corporations, associations and societies are putting forward their objectives to work towards net-zero emissions. For example, global fuel additive company Cataclean’s aim is to drive down carbon emissions, with Director Jason Sharman saying mining and infrastructure industries amount to approximately 25 per cent of the world’s carbon pollution.

“While heavy machinery is working hard output is high in both emissions and fuel consumption. Cataclean can reduce both of these environmental dangers, save money and [help] with the ever-increasing demand on companies to reduce emissions,” he says.

Additionally, speaking on behalf of the ASTT about the currently in-development Carbon Calculator, Mott MacDonald Water Sector Lead New Zealand Thomas Haarhoff says “reducing carbon emissions has almost become a moral obligation,” rather than simply an option.

Following the COVID-19 pandemic, this push for a cleaner future does not solely involve the benefits to counteracting climate change and the health of environment but the health of the population itself.

Creating a climate of health

Although the health benefits of a low-carbon world are currently topical, it is not a new phenomenon. In 2012, a Health and Environment Alliance report stated climate change and human health are deeply intertwined, which should be considered when new policies are developed.

“Moving to a low carbon economy will be associated with substantial health benefits,” says the report.

“These health benefits have a substantial economic impact everywhere, including in industrialised countries.”

While there are many health concerns associated with the human consumption of carbon emissions, notable occurrences include increasing air pollution levels that will lead to more widespread diseases, more cases of respiratory illnesses such as asthma and, ultimately, a higher fatality rate.

Counteracting these issues with low carbon emission solutions would benefit both humans and the environment, and help prevent a future wear protective masks are necessary to combat both contagious viruses and the air itself.

Change for change

‘Population health’ stems even further than the physical wellbeing of individuals and extends to the economy as well. Australia’s economy – like many others across the globe – has been severely affected by COVID-19; however, reducing emissions may be able to play a helping hand in bringing some much-needed pocket-change into Australia’s finances.

In 2019, the Melbourne Sustainable Societies Institute at the University of Melbourne released a report that found the nation would spend AU$535 billion on economic damage alone within the next decade if emissions continue at the current rate.

This means, by reducing carbon emissions and curbing the impact of damaging climate actions, the Australian economy would be AU$550 billion better off by 2030.

“Overall, the costs of emissions reduction are far less than the damages of inaction – even with modelling underestimating damages from climate change and overestimating the costs of emissions reduction,” the report says.

The reports authors Tom Kompas, Marcia Keegan and Ellen Witte find the change would present Australia with a sound economic development, where “the economic benefits of a transition to a clean economy easily outweigh the costs”.

Whether a company’s desire is to reduce its carbon emissions for the sake of counteracting climate change, preventing further illnesses from spreading to the population or to assist with economic recovery, it is clear the benefits of a low carbon economy can provide a brighter global future.

Longstanding trenchless relationship continues

For more than a decade, the contractor has relied on the German manufacturer for its high-quality and innovative products and support.

The partnership stretches back more than 10 years to January 2010 when R&R McClure first purchased a GRUNDODRILL 4X. The company has since assembled one of Australia’s largest collections of TRACTO-TECHNIK machines, including R&R McClure’s first GRUNDODRILL 28N+ in 2018.

When purchasing the new drill, R&R McClure Director Tim McClure says the company’s knowledge of TRACTO-TECHNIK’s products, their performance, durability and quality, as well as the company’s industry leading sales and service support, meant extending the relationship was the right choice.

“We have previously used a number of machines in TRACTO-TECHNIK’s range and we are extremely happy with the equipment and the digital technology they use for drilling and servicing,” says Mr McClure.

“We can always rely on our GRUNDODRILL rigs and on TRACTO-TECHNIK. This goes for their efficient and effective machine technology, as well as for the fantastic support provided by the staff in Brisbane and Germany.”

The GRUNDODRILL 28N+ in action on a recent HDD project.

GRUNDODRILL 28N+

The GRUNDODRILL 28N+ is one of TRACTO-TECHNIK’s most popular and best performing fluid-assisted horizontal directional drilling (HDD) rigs. The compact 7.5 m machine achieves peak results in every discipline through its powerful drive and best-in-class values.

Mr McClure says the 28N+ is highly effective when completing long length bores.

“It is very quiet, smooth to operate and has plenty of power,” he says.

The vehicle’s existing drive power is 224 kW from a Tier 5 Cummins engine, which is 100 per cent converted into drilling power with up to 300 kN pulling force. The GRUNDODRILL is also fitted with a 650 L bentonite pump allowing for maximum productivity and fast drilling progress, even with large upsizing diameters.

“We purchased a second drill to allow better efficiency on long projects and provide availability where tight time frames are required,” says Mr McClure, adding that parts of the machine such as rods and drill bits can be shared and interact with the many other TRACTO-TECHNIK machines already present in its fleet.

With its slim design and minimal distance from drilling axis to the outer edge of the machine, the drill has the largest rod magazine in its performance class with 288 m of usable drill rods onboard. It also has 11,000 Nm of rotational torque with thrust and a pullback of 280 kN.

As it is fully automatic and has a particularly ergonomic design for the reloading of drill rods, no machine operator is required within the cabin and it offers the ability to log bore data and complete data transfer tasks with ease.

A proven track record

Mr McClure says the GRUNDODRILL 28N+ machines have both been used on an underground power project that is part of the bushfire prevention plan, as well as on water main works and private trade projects.

“The GRUNDODRILL 28N has a vast range of unique features that we were looking for and these will assist in the future as we continue to develop our business.”

In particular, the 288 m on-board rod length stands out as it allows R&R McClure to achieve these longer drill lengths without having to change its whole rod basket as it would with other machinery.

Notably, the high-quality machinery allowed R&R McClure to achieve single bore lengths of more than 250 m, which also reduced the quantity of bore start and end holes.

“We were also able to achieve an efficiency that could meet project timelines,” says Mr McClure.

When looking at future projects, Mr McClure says the company will mostly be using its 28N+ machines on “work that requires long bore lengths in all ground conditions that require a trenchless solution”.

Personal support

To ensure its customers get the most out of their machinery purchases, TRACTO-TECHNIK offers continuous training on service and maintenance of its systems and guarantees comprehensive and rapid repairs. For personal requirements, TRACTO-TECHNIK says it can train its customers according to individual requirements.

Mr McClure can attest to this, saying R&R McClure is always extremely happy with the service and communication it receives from the team at TRACTO-TECHNIK Australia, and has been for the entirety of its longstanding relationship.

Rob Carr TBM

Driving through dirt and rocks

While the situation on Melbourne’s streets continues to evolve, below the surface Rob Carr grapples with its own challenges, using its microtunnelling expertise to overcome any obstacle.

The sewer network in Melbourne’s CBD is approximately 120 years old and is relied upon by a rapidly expanding population, with Melbourne’s entire population now closing in on 5 million. To ensure this vital network can cope with the needs of the reliant homes and businesses, City West Water (CWW) appointed civil construction and tunnelling expert Rob Carr – in association with design partner SMEC – to complete the Lonsdale Street Sewer Upgrade.

The project is the second stage of a four-stage strategy to install a secondary 900 m long sewer line under Lonsdale Street, with Rob Carr to deliver a DN 1400 glass fibre reinforced plastic (GRP) sewer line using a microtunnel boring machine (MTBM) for its construction.

After launching the MTBM from its 23 m deep launch shaft on William Street in early 2020, Rob Carr completed its first drive of approximately 550 m. The machine has now been turned around and commenced jacking on the second line, which is to be 350 m long.

Rob Carr is also simultaneously completing a new 23 m tunnel into Elizabeth Street using a hand jack, which will be tied into an existing manhole at that location.

The MTBM breaks through underneath Lonsdale Street.

Above the surface

While the tunnelling operations continue to run 24 hours a day, six days per week below the surface, Melbourne’s above ground situation continues to be impacted by the COVID-19 pandemic. After briefly easing restrictions, several virus outbreaks in Victoria have forced residents to return to strict lockdowns and once again increase prevention measures.

Rob Carr and CWW have been adhering to all coronavirus prevention guidelines onsite, allowing the project to continue running at full power. Border closures have forced some interstate workers to remain in Victoria, but Rob Carr Construction Manager Andrew Scarr says everyone involved has been able to deal with the changing conditions.

“It has an effect, but we have managed to work around any of those challenges,” he says.

“Later this year we hope to complete the line we are constructing at the moment, tie into the manhole on Spencer Street and complete the manhole at the launch shaft.

“The project has had its challenges, but we’ve continued to move forward and are steadily delivering these sewer upgrades.”

Rob Carr aims to complete its works later in 2020.

Bothar’s critical seaway project a success

Over the past 20 years, the Gold Coast has seen unprecedented growth causing its existing excess recycled water release infrastructure to approach its capacity and capability. Thanks to the work of the Bothar team, the city’s recycled water infrastructure is now future proofed for the expected population increase over the next two decades.

Project specification

The installation of the new pipe was completed using a Herrenknecht AVN2000AB Tunnel Boring Machine (MTBM), with Bothar’s Project Manager Kieran O’Connor saying this could be the longest subsea microtunnelling drive completed in the southern hemisphere.

Bothar was also responsible for the temporary works design and construction of launch and retrieval shafts required for pipe jacking operations. The launch shaft at Quota Park in Biggera Waters was 26 m deep and 12.5 m diameter secant piled construction with the reception shaft – a 7.5 m diameter, 26 m deep pre-cast segmental sunk caisson – situated at South Stradbroke Island.

Mr O’Connor says Bothar was engaged to be the project’s specialist subcontractor on this critical seaway project.

The project’s first MTBM ready for launch.

First stages complete

In May, Bothar’s first MTBM resurfaced from its 1,385 m subsea crossing underneath the Gold Coast Broadwater, signalling the completion of the project’s first stage of tunnelling. Over the coming months, an AVN1500 – the project’s second MTBM – will be used to tunnel between Quota Park and O’Connell Park.

Both MTBM’s were manufactured by Herrenknecht and have been sourced from Bothar’s extensive international fleet of Herrenknecht machines.

Risk mitigation technology Mr O’Connor says the decision to use microtunnelling was born out of a need for risk mitigation considering the inherent technical, safety, environmental and community risks associated with the complex and challenging tunnel.

“Microtunnelling provided the optimal balance of innovation and risk mitigation,” he said.

“The subsea crossing was constructed underneath the seabed of an environmentally protected area of Moreton Bay providing for its continuous use by the local community for boating, fishing and recreational activities.”

In addition to the challenging tunnelling task, the hurdle of COVID-19 also arose during the project. To overcome social distancing restrictions and complete its essential project, Mr O’Connor says Bothar implemented strict protocols for its staff, including daily temperature testing and hygiene practices.

Bothar’s dedication to mitigating risks both to the environment and to its own workforce during the project demonstrates its commitment to finding a successful solution regardless of the challenges faced.

No catch-22 with MCS on board

McRobert Contracting Services (MCS) is an Australian-owned and operated industry leader in the refurbishment of underground assets and polyvinyl chloride (PVC) pipeline technology. Operating out of Perth, WA, the company has been in operation for more than 30 years and has evolved into a business whose specialised services are sought out by both public and private sectors around the country.

MCS has worked on hundreds of projects across its lifetime and has developed a unique patented method for the structural relining of access chambers suffering from sulphide corrosion. The company’s strong relationships with a range of water operators across Australia are helping it achieve its vision of being the first choice for rehabilitation services, backed by its consistent ability to offer industry leading services and products to existing and future customers.

Doing what MCS does best

On 12 June 2020, MCS – in association with the Water Corporation – completed a contract to rehabilitate 22 access chambers that were deemed to be of an extremely poor condition in Cottesloe, WA. Before the actual refurbishments began, MCS employed its latest 3D scanning technology to assess the structural integrity of each access chamber and cross reference detailed measurements to determine the assets’ conditions.

These reports provided critical information for the method of rehabilitation MCS would use. The chambers were predicted to be challenging due to their high flows, silt/debris content, already fragile overall structure, advanced age and proximity to Cottesloe’s popular beach front.

After careful deliberation, it was decided to carefully jet-wash and e-duct approximately 5 m either side of each chamber to reduce the otherwise high cost to clean and e-duct kilometres of pipeline. This jet-washing/e-ducting process was also able to assist in reducing the amount of silt and debris in each chamber.

Additionally, the jet-washing and e-ducting significantly lowered the flows along with the isolations provided by Water Corporation to a workable level. This decision, as well as having the capacity to work with the prefabricated channels, allowed MCS to specifically adapt and design a solution to allow for the successful and safe installation of channel and benching with the remaining refurbishment works to be completed prior to the allocated project schedule.

The specific scope of works for this project comprised the design and development of structural rehabilitation for the current asset structure using approved remedial methods, including surface preparation for rehabilitation, channel and bench fabrications and the installation of the PVC lining system.

This also included the supply and installation of all required lining materials, supply and installation of PVC lined lids, reinstatement of property to previous conditions, spark testing completed to Water Corporation standards and the provision of quality assurance documentation.

Track record of success

When faced with a relining project, MCS uses a minimum 10 mm rigid PVC sheeting, with the chamber walls prefabricated into sleeves that can be lowered into place directly onto the asset. MCS also prefabricates the PVC channel and benching components, which are then plastic welded into place in the chamber.

After installation, the preformed sleeves, channels and benching are secured to the original asset using a minimum 40 mm of high strength grout. MCS relines the access chambers from top to bottom including pipe connections, channel and benching resulting in a 100 per cent gas tight structural PVC lining. This ensures complete protection of the asset from concrete deterioration.

The final result of the rehabilitated access chamber.

Although MCS guarantees a period of 50 years for the plastic lining of utilities access chambers and sewer pumps, PVC linings should last significantly more than 100 years, provided no physical damage or prolonged exposure to UV occurs.

Continued excellence

MCS has developed its relining methodologies to ensure it maintains a safe working environment while completing tasks in the most efficient manner possible. The company aims to spend as little time in the chamber as possible, equating to less time spent onsite and minimising extra costs that can accompany issues like traffic management.

Although based in WA, MCS has, and continues to, offer and complete its services around Australia. Along with access chamber refurbishments, these services include sewer pump station refurbishments, plastic fabrication, onsite fabrication, 3D laser scans, pressure jetting and CCTV inspections.

A wide range of relining successes

With the company’s longstanding philosophy “keep it running”, Rangedale offers the expertise, capability, resources and scale to take on projects large and small – evident in its recent relining successes throughout the state.

The trenchless technology expert has added new systems to its existing range of rehabilitation products and increased its relining capabilities, which now include ultraviolet (UV) lining, inversion, fibreglass patching and Smart Lock technologies.

Rangedale has exemplified its capabilities on a recent major infrastructure project utilising the use of high-definition CCTV, high-pressure water jetting, patching and UV lining over a two-month period to rehabilitate the damaged storm water assets.

Due to the heavy-traffic location, Rangedale was required to create a works methodology to offer a solution that avoided disruptive excavation work. First, Rangedale used its CCTV cameras to ascertain the asset’s condition and completed drain cleaning requirements to mitigate any sharp or other potential hazards that could damage the liner during installation.

By using its new state of the art relining system, Rangedale used UV light during the installation process to reduce curing time, increasing productivity and allowing a cost-effective trenchless rehabilitation solution with minimal impact to key stakeholders and the community.

On another recent project, Rangedale continued to demonstrate its relining capabilities by completing a 100 linear metre UV reline on a DN 225 live sewer. Rangedale said concrete slurry from adjacent construction works infiltrated the sewer network then cured, causing a significant blockage issue.

The use of specialised robotics were then implemented by Rangedale for a duration of approximately two weeks to remove the concrete with cutting and grinding tooling.

Upon completion of the removal, Rangedale installed the liner to rehabilitate the damaged sewer.

The UV system consists of a flexible tube made of glass fibre that is impregnated with a reaction resin composition and then pulled into place in drains and expanded using air pressure before the curing process is completed. The finished product is a statically stable, seamless, flexible pipe.

Turnkey solutions

Rangedale offers complete in-house, innovative turnkey solutions, providing the best rehabilitation technologies and methodologies while ensuring the asset owner and end user receive great value.

For these listed projects, Rangedale installed approximately 50 Smart Locks that were manufactured locally and specifically for the task, including sizes of DN 825, DN 1050, DN 1800 and DN 2250, demonstrating the company’s full service approach to its projects.

Rangedale’s relining methodologies can be employed for all pipe and sewer rehabilitation and are applicable to drainage materials such as concrete, steel, vitrified clay, fibre cement, glass reinforced plastic, un-plasticised polyvinyl chloride, high-density polyethylene and cast iron.

By using its new UV lining system in collaboration with existing rehabilitation solutions, Rangedale can reduce curing times and provide a cost-effective rehabilitation solution through an environmentally friendly process.

Aussie Trenchless moves FNQ project forward

As trenchless technology continues to make its mark as the preferred installation method for underground infrastructure, Aussie Trenchless remains at the forefront of the industry with innovative new products and technology.

Growing in popularity

The company’s flagship product is a close fitting structural spiral ribbed PVC trenchless pipe lining system titled the SRP EXP. Used for circular sewer and storm gravity mains, the method continues to grow in popularity and will now be used on the recently-awarded FNQ project.

When the SRP EXP is installed, asset operators will extend the service life of a system by more than 50 years. Although designed to fit standard size access chambers, the product is also ideal for tight spaces or those with limited access.

Since the installation process is its unaffected by running infiltration and does not require bypass pumping, SRP EXP is well suited to water applications, particularly as it also enhances the hydraulic characteristics of the rehabilitated asset.

Aussie Trenchless Director Chris Meredith says he has seen significant growth in the implementation of this trenchless solution both around the world and here in Australia, where it continues to be implemented in relining projects, including in its repeat customer Relining Solutions’ upcoming contract.

Major improvements were already evident in the middle of the Ravenshoe Project.

Customers keep coming back

Relining Solutions is not the company’s only repeat customer, Mr Meredith says, with an international customer based in Taiwan ordering more supplies to be delivered in September this year.

“In 2019, the customer purchased 50,000 linear metres and have since been installing that,” says Mr Meredith.

“They have now placed another order of 60,000 linear metres, which are being manufactured as we speak.”

Mr Meredith says the customer is an active player in the Taiwan sewer industry has been for a substantial amount of time, often using Aussie Trenchless supplies for its projects.

Mr Meredith adds that this is an example of how customers are taking advantage of the product, with the company also receiving lots of market feedback indicating it is one of the most financially viable and efficient systems available.

“Like all efficient trenchless methods, the spiral lining system helps ensure the project’s aboveground footprint is minimised as much as possible, which includes the land and environment itself, as well as the day-to-day lives of the public in surrounding areas,” says Mr Meredith.

A successful range

While the SRP EXP is at the forefront of Aussie Trenchless’ market offerings, the company’s Hot Sleeve Jacket is also popular due to its prompt resin curing times.

The Hot Sleeve is a tight-fitting heating jacket that is secured over a patch inflatable packer to reduce ambient cure period without any life reduction, saving operators up to 60 per cent in crew times.

The Ravenshoe Project beginning to improve after showing severe signs of deterioration.

Aussie Trenchless also offers the market a man entry lining system using transparent polypropylene lining panels for the rehabilitation of gravity sewer mains, namely its Pipe Segment Technology (PST). PST is easy and fast to implement with lining panels made of polypropylene material providing a smooth surface and excellent hydraulic performance characteristics.

Relining SIG gets reformed

In 2016, the Linings SIG was formed to develop standard specifications that all asset owners in Australia and New Zealand could use with confidence.

After limited success at the time, the ASTT is now proposing to resurrect the group that at this stage will be chaired by New Zealand Councillor Blair Telfer.

The group intends to develop training courses and material for pipe lining, similar to the North American Society for Trenchless Technology (NASTT) courses but instead with an Australasian perspective.

ASTT Secretary Jeff Pace said the SIG is always open to other suggestions and ideas from individuals and companies as to what the industry needs and wants.

To register your interest for the SIG, please contact jeffpace@astt.com.au
