Melbourne Water named international finalist
The award recognises outstanding organisations and projects at the forefront of public participation and community engagement, in which Melbourne Water has been recognised for its innovative Next Generation Community Engagement Program (NextGen).
WATCH: Time lapse of trenchless project
Filmed over 6 out of the job’s 10-day work program, the video shows the replacement of 548.64 m of a 30 inch (762 mm) watermain at the insertion and receiving pit.
The CompressionFit pipe lining method was incorporated for the project.
This HDPE pipe lining technology specifies an HDPE pipe with an outside diameter larger in size than the inside of the host pipe..
After the HDPE is butt fused to correspond to the pull distance, the pipe is pulled through a reduction die immediately before entering the host pipe.
This reduces the HDPE pipe temporarily below the ID of the host pipe allowing it to be inserted.

MMRC completes 33rd breakthrough
The tunnel will run from Churchgate to Hutatma Chowk station as part of the corporation’s Metro 3 Corridor project.
The breakthrough is the first of its kind inside the tunnel using a dual mode hard rock tunnel boring machine (TBM), which has completed the downline stretch in 275 days using 502 rings.
MMRC Managing Director Ranjit Singh Deol said the various heritage buildings nearby the project works made the task “a bit challenging”.
“However, this unique station, in the vicinity of Hutatma Chowk, is being built by using a combination of Cut-and-Cover and New Austrian Tunnelling Method (NATM),” he said.
“This station will provide accessibility to the business centres of South Mumbai.”
Package 1 of the project consists of Cuffe Parade, Vidhan Bhavan, Churchgate and Hutatma-Chowk stations, and is now more than 50 per cent complete.
Following the recent breakthrough, the total tunnelling of the project is now 88 per cent complete.

DBYD expands internationally
DBYD’s program ensures locator operators are certified to find critical underground utilities and infrastructure before excavation work is carried out, with companies like Telstra and Optus already requiring locators to be certified through the program before access to networks is allowed.
Now, with assistance from intellectual property expects Macpherson Kelley, the DBYD Certification firm is going international and has licensed its program to Locate Management Institute as the Canadian Certified Locator Program.
Macpherson Kelley Special Counsel Mark Metzeling said DBYD Certification’s training materials and methods were valuable intellectual property, with the firm being recognised as an international leader in locator certification standards.
“By taking this knowledge and formalising it as a program, through the use of a certification trademark, we were able to instil formal standards that are fast becoming the benchmark in Australia and now overseas,” he said.
“DBYD Certification also has further international ambitions and protecting its logo will ensure its brand is recognised as one that can be trusted.”
DBYD Certification CEO Robert Row said the program ensures people working as locators had the skills and experience to identify underground assets.
“Before the program there was no objective criteria to determine whether the locator you’ve hired was competent or not to do the job,” he said.
“Now companies know when they use someone who has completed the DBYD Certification program they have been through rigorous testing and assessment.”
Mr Row said the program first when international when introduced to New Zealand in 2019 and has more plans to expand the program across the US, UK and Singapore.

Interflow provides essential water services
Despite access to clean water, decent toilets and good hygiene being fundamental human rights, millions of people around the world are not afforded these necessities, which is why Australia’s water industry is putting its financial power behind not-for-profit organization WaterAid.
Extending a helping hand
Established in 2004, WaterAid Australia provides communities in developing parts of the Asia-Pacific region with access to fresh water, sanitation and hygiene products.
The organisation has made transformational change over the years, giving disadvantaged people access to this vital life source, while promoting safe and healthy habits at a community level.
With over 80 years’ experience in the water industry, specialist in water infrastructure, Interflow, understands the value that WaterAid’s work brings communities, and has been a proud sponsor of the organisation for more than 15 years.
Having witnessed the difference that ready access to clean water and sanitation can make first-hand, Interflow Managing Director Geoff Weaver said the organisation’s mission is very important to him.
“Supporting our customers’ local communities through the provision of safe drinking water and sanitation is a big part of what we have done throughout our history across Australia and New Zealand, but a lot of our neighbours throughout the Asia-Pacific region aren’t as fortunate,” he said.
“Access to these services is vital to enhancing the quality of life and general prosperity of communities and can impact a child’s access to healthcare and education.
“We want to do our part to ensure that all families, communities and businesses gain access to such utilities, regardless of the circumstances they were born into.”
By making these services more accessible, WaterAid and its partners are giving local leaders and townships the tools they need to support the growth of a healthy community for generations to come.
Delivering tailored support
COVID-19 has reinforced the importance of hygiene and sanitation on a global scale and WaterAid’s work through these difficult times has played an enormous role in preserving the health of vulnerable communities.
By providing national communications, information, materials and training on water, sanitation and hygiene, WaterAid’s volunteers are not only protecting rural communities from mass infection but improving the health of future generations.
Mr Weaver explains how uniting behind this cause has enabled members of the Australian water industry to amplify their positive impact.
“Without an intimate knowledge of the social or political systems in these regions, or what the needs of various local communities are, the impact of an organisation looking to make a difference on its own would be limited,” he said.
“The people at WaterAid have the specialist knowledge and local resources to be able to put our money where it’s needed.
“They’re channeling the collective power of the Australian water industry and helping us all to achieve a greater good on a much larger scale.”
Stronger together
The united approach of water authorities, government bodies and essential service providers such as Interflow, has enabled WaterAid Australia to leave a lasting impact in hundreds of communities throughout the Asia-Pacific.
WaterAid’s sponsors have supported the organisation’s work in Cambodia, Papua New Guinea and Timor-Leste with an increased focus on hygiene education and promotion, which is vital to prevent the spread of COVID-19.
With its eyes set on more community-based initiatives to further elevate the health of those in need, both through and post-COVID-19, WaterAid’s work is a potent reminder of how working together can truly change lives for communities around the world.

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.”
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.
