Primus Line® advances in Australia

It goes without saying that infrastructure for water supply will always be relevant.  

However, much of this infrastructure is ageing, with leaking or even shut down pipes underlining the necessity for renovation.  

Usually, these pipes are renewed or revitalised by dig-and-replace, but over the past few years, utilities worldwide are looking more and more for trenchless solutions.  

The advantages are clear: shorter installation times, fewer impacts on the environment and reduced costs.  

Primus Line® – engineered and manufactured in Germany – is one of these solutions, consisting of a flexible, aramid-reinforced liner and special developed end fittings.  

Since Sydney Water undertook its first Primus Line project four years ago, nearly a dozen have followed, along with the projects for other utilities, councils and mining companies throughout Australia.  

These include Urban Utilities, Hunter Water, Unity Water and Shoalhaven City Council, to name just a few.  

Primus Line technology is currently the sole solution for the rehabilitation of pressure pipelines on Sydney Water’s list of products deemed to comply with pipeline rehabilitation.  

In cases of water spilling from damaged drinking water pipelines or sewage pressure lines in hard to access areas, such as beneath a creek, rapid response is essential.  

This is why some Australian pipeline operators already have Primus Line material on stock to present fast remedy in emergency cases, with Primus Line now found in even the most remote corners of Australia.  

In Cape Lambert, Western Australia, more than 1.5 km of drinking water pipelines have been rehabilitated using the product for Rio Tinto at a site of cultural heritage sensitivity.  

Other customers from the private sector, including Melbourne Airport, have already profited from the German trenchless renewal system, but Primus Line is used for more than just the rehabilitation of potable water mains – the range of completed projects extends to sewage pressure pipes, recycled water or raw water mains as well.  

Moreover, the Primus Line has been used on projects deemed nearly impossible. Examples include a 3-in-1 solution for Hunter Water (three Primus Liners DN 450 installed in a DN 900 pipe) and a vertical pipeline of more than 100 m for Sydney Water.  

To plan and calculate the projects, Primus Line relies on its in-house engineering team that gets to work immediately from project start, ensuring the Primus Line technology is the right product to carry out the job quickly and efficiently.

APLNG proposes HDD for gas wells

A joint venture (JV) between Origin Energy, ConocoPhillips and Sinopec, APLNG is seeking federal approval to drill thousands of new gas wells in Queensland as part of its Gas Supply Security Project. 

In its referral documents, APLNG said it would construct the wells using HDD and would also incorporate this technology for drilling of pipelines under threatened ecological communities, threatened flora, threatened fauna habitat and migratory fauna habitat.  

The JV cited forecast gas supply shortfalls from 2024 onwards as reason for undertaking the new drilling activity, as well as the potential for increased gas demands and increased reliance on Queensland supplies as production from Victoria continues to decline. 

The new gas would be used for both the domestic gas market and the export demands of APLNG, with current appraisal data showing production from 2P resources expected to be 453.6 PJ of gas. 

If the proposal is successful construction is likely to commence in 2024.

Decoding pipe choices for microtunnelling

Contractors and asset managers alike should ask themselves the question – are they selecting or inheriting the right pipe?  

CivilCode Managing Director John Bower can help with the answer.  

Along with founding and managing the software development company CivilCode, Mr Bower is also a consulting engineer and the Principal of Independent Civil Solutions.  

With extensive experience in the industry, Mr Bower offers expert advice for pipe selection that is second to none.  

MDG-S Mr Bower said the recent release of the Microtunnelling Design Guidelines for Sewers (MDG-S) has provided an opportunity to revisit some important design fundamentals.  

Plus, with the increasing capability of methods of installation often involving installation of relatively low stiffness pipe, it has become even more important to understand what strength of pipe is required for the permanent design loads.  

“Whether it is installing a steel pipe under a major highway or a GRP jacking or sleeve pipe in a microtunnel under a railway line, understanding the minimum required strength or stiffness of pipe is fundamental,” said Mr Bower.  

“Over the past few years, I have written a number of papers on this subject, and I was verypleased to have been able to contribute to the MDG-S.”  

The MDG-S explains that most pipes can either be classified as rigid (such as concrete or clay) or flexible (such as PE, PVC, steel, GRP and polypropylene).  

For rigid pipes, the existing design standard provide equations for calculating the relevant permanent design loads for bores or trenchless installations.  

“The only difference between the loads for a conventional (trench or embankment) or a trenchless installation, is how the soil loads are calculated,” said Mr Bower.  

However, in recent times, more and more flexible pipes are being installed using microtunnelling, particularly for sewerage installations.  

“The relevant design standard for structural design of flexible pipes is AS/NZS 2566.1, although this standard does not provide guidance on bored or jacked installations.  

“But, as stated in the MDG-S, the commentary to AS/NZS 2566.1 (Supp. 1) does provide details as to how soil loads can be calculated for “bores”.  

“Other loads can then be determined using the other sections of AS/NZS 2566.1.”  

Mr Bower said, ultimately, the main differences between a trenchless and a conventional trenched installation are how the soil loads should be calculated, what side support can be expected and how the design equations can and should be applied.  

“As explained in the MDG-S, effective grouting of the annulus can be an important part of the design to ensure side support from the native soil can be relied on,” he said.  

“Although not included in the MDG-S, it is also possible to carry out a design based on the pipe stiffness alone if the grouting is unlikely to be effective or cannot be completed for some reason.”  

FlxPipe Software  

“If you are thinking that this all sounds a bit complicated, fortunately CivilCode has made it easy for both designers and contractors alike,” said Mr Bower.  

In 2020, CivilCode released a trenchless design option for its FlxPipe design software, being an online application for structural design of buried flexible pipes to AS/NZS 2566.1.  

The new trenchless option allows for the design of both new pipe installations and pipeline renovation.  

With a company-wide aim to produce civil engineering design software to remove the drudgery of manual calculations while retaining transparency at all stages of the process, CivilCode will guide users every step of the way including training on design theory and using FlxPipe.

Liner won’t croak after quake

The company’s AM-LINER II® is a method for rehabilitating damaged wastewater and stormwater pipelines encompassing these qualities and has proven its strength under the most intense environmental circumstances.

PipeTech’s AM-LINER II is manufactured from a polyvinyl chloride (PVC) compound specifically formulated for pipeline rehabilitation and is resistant to all normal sewer effluents due to its superior chemical and flame-resistant properties. It is manufactured in a factory and not in the ground, with the physical properties of the liner known at the time of manufacture rather than weeks after installation.

AM-LINER II provides a cost-effective, minimally disruptive and efficient means of rehabilitating even severely damaged sewer pipes. Once installed, the PVC liner is continuous from manhole to manhole, eliminating leaking joints, root intrusion and further damage to the existing host pipe by corrosive sewer gases.

There are no hazardous chemicals to handle, no noxious odours and no hazardous materials released into the environment, while the smooth interior surface even transitions through offsets to give enhanced flow characteristics to the rehabilitated pipeline.

The PipetTech team busy on site installing the AM-LINER II, designed to withstand even the toughest conditions.

Tried and tested

Following the 2010–2011 Canterbury earthquake on New Zealand’s South Island, the region’s wastewater network was extensively damaged, causing issues for communities affected by the shock. The earthquake showed liquefaction and resulting ground deformations caused major geotechnical hazards to civil engineering infrastructures such as pipelines.

In particular, sewer pipes have been damaged in many areas of Christchurch as a result of liquefaction-induced lateral spreading near waterways and ground oscillation induced by seismic shaking. While most of the damaged sewer and water pipes in Christchurch were in sections made of asbestos cement, several segments of PVC, concrete and polyethylene (PE) pipes were also sheared, pulled out or compressed at various levels, with these damages affecting the sewer network’s functionality in many places.

A study comprising an extensive thesis completed by then-Auckland University student Shyamal Ram investigated the performance of sewer pipes equipped with the AM-LINER II during earthquakes and established its performance as a structural retrofitting measure to earthquake-proof sewer pipes.

The key objective of this research was to analyse the response of buried sewer pipes to liquefaction induced permanent ground deformation, particularly in the transverse direction and was completed by investigating the use of a flexible liner as a potential countermeasure to increase pipe capacity. Underpinning this study was the goal to ultimately retain pipe serviceability following an earthquake, thereby reducing community impacts and rehabilitating the wastewater network.

On average, the AM-LINER II increased the displacement capacity by 191 per cent, with the results confirming the product as an effective countermeasure for sewer pipes in liquefied ground, not only in terms of increased deformation capacity, but also because AM-LINER II can prevent an influx of sand and water through broken pipes. This allows sewer pipes equipped with the liner to remain serviceable even under severe liquefaction conditions.

As a result, restoration of damaged pipes can be delayed so that attention can be provided to more important services or facilities.

Repeat customers

PipeTech has been consistently lining pipes for a range of clients and councils throughout NZ, including Veolia Papakura, New Plymouth District Council, Stratford District Council, South Taranaki District Council, Whanganui District Council, Manawatu District Council, Fulton Hogan (Wairoa District Council), Ashburton District Council, InPipe Logistics (Fonterra) and Port Taranaki.

Manawatu District Council Special Projects Manager Chris Pepper praised the AM-LINER II as a reliable and efficient trenchless product.

“The AM-LINER II is quick and easy to install, is a fully structural product, has a proven seismic response and a demonstrable life cycle well in advance of 100 years,” he says.

“It is fully compatible with other trenchless inspection and repair techniques for sewers, including Later Joint Repair (LJR) products.”

Whanganui District Council Engineering Officer Chris Carter added that the council has used the reliable product since 2011 with no issues.

“Easy and quick to install with seamless lengths of a stable material, WDC have found it an excellent solution to remedy infiltration, root intrusion and structural faults,” said Mr Carter.

Another long-term user of the AM-LINER II, South Taranaki District Council Senior Projects Officer Colin Dudley, said the product allows for the option of “relining over replacing many of our sewer lines, with far less disruption to traffic flow and no road reinstatement required”.

The AM-LINER II is PipeTech’s exclusive product range, with the company being the sole licenced distributor in NZ.

One Shot, plenty of opportunities

One Shot Directional Drilling (OSDD) is a horizontal directional drilling (HDD) specialist, with its history of projects spanning crossing waterways, roadways and environmentally sensitive areas where other trenching methods are not possible, all throughout Queensland and in the northern New South Wales region.

Most recently, OSDD has been completing drilling projects on various farms in the Lockyer Valley, Queensland, as HDD is an ideal method for sites sensitive to surface disruptions – such as farming crops.

OSDD would drill under the road and now, upon completion of the drills, farmers can provide fast irrigation for crops on the opposite side of the road to where the dam or water wells are situated.

A durable solution

OSDD Managing Director Adrian Brock says the team has completed many drills on farms within the region, all within very quick timeframes. Each project has taken no more than 2-3 days, with OSDD installing HDPE PN16 blue stripe of varying lengths and sizes at Lilydale Farms, Huggins Organic Farms, Windolf Farms and more.

Mr Brock says HDPE PN16 blue pipe was chosen for the projects due to its high durability, ability to be used for a diverse range of applications and its non-corrosive, chemical resistant properties. The pipe is available in a wide range of thicknesses and pressure ratings, with fittings and equipment to create an entire system, with such versatility necessary for the various jobs.

“Poly pressure pipes are designed for a long lifetime (in excess of 100 years) in underground infrastructure,” says Mr Brock.

“Installing the pipe in the ground is typically the most expensive part of the operation (usually 85-90 per cent of the project costs), therefore the long life and durability of poly piping remove the need to regularly replace pipes within their working lifetime.”

In addition to its long life and durability, the HDPE PN16 pipe is lightweight and flexible, which allows for an easier and more cost-effective freight, handling and installation.

To complete the installations, Mr Brock says OSDD used a Vermeer D9x13 Series III Directional Drill Rig, Ditch Witch JT2020 Directional Drill Rig, Ditch Witch FX30 Vacuum Excavation Truck and a Digitrak F5 Falcon Locator.

“True professionals”

Lilydale Farms Pty Ltd Farm Manager Ryan Folkard – who knew underground drilling existed but didn’t know where to start before finding OSDD online – had the first drill completed by the team earlier this year, and has continued to call upon them since.

Mr Folkard says the team are “true professionals” who are on time, well organised and dedicated to safety – both from a traffic point of view as well as the job they are doing.

Mr Folkard also says the OSDD team are so helpful that they didn’t shy away from doing him a favour while onsite with their vac truck – solving a cable issue he’d had for quite some time.

“In the past, I had other contractors come up and try to find a fibre optic cable with no luck. Adrian found it in about an hour,” he says.

Mr Folkard adds he would “150 per cent” recommend the company to other farmers in the region – something he has already been doing.

Huggins Organics Farm Owner Troy Huggins found out about OSDD through Mr Folkard, with his own drilling job being completed a month ago. Mr Huggins shares Mr Folkard’s high opinion of OSDD drilling, saying the team is “very prompt, very polite and very professional”.

“They do a neat and tidy job, don’t leave a mess around,” said Mr Huggins.

“It’s never a drama for any questions, they’d answer them straight away and if you need paperwork, it’d be sent through straight away. They’re absolutely fantastic.”

A wealth of experience

Mr Brock established the family-owned business in 2017, after gaining more than 20 years of experience in the HDD industry himself. Since then, OSDD has grown to specialise in HDD and underground boring services for the installation of conduits for water, gas, power and telecommunications all across the Sunshine State and northern NSW.

Wilmot expands rehabilitation offerings

Wilmot Pipelining conducts rehabilitations of pipelines of all sizes and shapes to upgrade asset owner’s infrastructure and keep it operational. By using trenchless technologies, Wilmot can transform ageing and failing infrastructure with minimal disturbance. 

The company says it provides many different pipeline rehabilitation methods to its clients and prides itself on finding a suitable solution for any and all situations. With a strong background in pipeline construction and hydraulic services, the Wilmot team says it has a “good understanding of the way pipelines are constructed”. 

With most of its infrastructure upgrades carried out on municipal assets such as water, energy providers, wastewater, industrial facilities and refineries, Wilmot says it is now offering clients the rehabilitation of pits and manholes using its UV curing method that can complete a restoration in a matter of hours. 

The company ensures that similar to its other trenchless offerings, its new liners are installed quickly and with no impact on the network while carrying out the renewal procedure. 

World first

Wilmot Managing Director Andrew Wilmot says manufacturer Brandenburger Germany has created one of the first pioneered CIP cured manhole liners, which the company is now proud to be installing for its Australian clients. By using the innovative system, manholes and pits are transformed back to fully operational with a 50-year warranty on the asset. 

“As a pioneer and one of the world’s leading manufacturers of UV CIPP, Brandenburger Liner has used its experience to develop an innovative method for manhole rehabilitation,” says Mr Wilmot.  

“The Brandenburger Manhole Liner BBS.8 reduces logistical effort for our customers at the job site and allows an efficient, as well as holistic rehabilitation of the sewer network including manholes and sewers.” 

Mr Wilmot says the UV manhole liner adapts to the shape of the manhole solely by air pressure, which prevents any time-consuming measurements of the manhole in the lead up to the rehabilitation. 

“The specially designed stretchable GFR laminate generates three important advantages,” says Mr Wilmot. 

“Beforehand, no measurements of the old manhole are necessary, only the size of the manhole opening and the size of the manhole itself are needed. Secondly, there is endless production – with the special production technology, Brandenburger is able to produce all manhole liners at a stretch for diameters between 800-1,000 mm.” 

The Brandenburger UV liner being used by Wilmot Pipelining on a recent project.

Mr Wilmot says the third advantage is rehabilitation can now occur from the bottom of the manhole up to the sewer pipe. 

“With a special installation procedure, it is also possible to rehabilitate the bottom of the manhole with the Brandenburger BBS.8 material.” 

The Wilmot main office and depot is located in Newcastle, New South Wales, although the company can service all areas of Australia, offering homeowners and municipal asset and infrastructure organisations rehabilitation services using trenchless methods. 

Additional offerings

Alongside its many relining offerings, including UV lining, hot cure lining, point lining and patching, lateral seal lining and manhole repairs, Wilmot also offers various other trenchless services. 

As a Hunter Water Accredited Hydraulic services provider, Wilmot can construct new sewer and water mains. The team says its knowledge and experience gained from working on large-scale projects for more than 20 years has provided the confidence to deliver projects on time and within budget. 

Wilmot says it also has a diverse range of robotic cutters, including down the branch cutters, HSL cutters, reticulation cutters and beast cutters for medium to large bore pipelines, adding it can open up newly relined junctions and connections or remove large concrete deposits from pipelines. 

Additionally, the company produces high quality CCTV reports and assessments for its clients with the industry standard report system ‘Wincan’ to provide condition assessment and pre-and post-relining reports. 

Wilmot says it provides a complete pipeline rehabilitation service to its clients by including pipeline cleaning and waste disposal in its offerings, and completes this service using many different sized high-pressure water jetting and non-destructive digging units. 

“The Wilmot team pride themselves on having a cost effect and most non-destructive solution for any situation,” the company says, adding that it is an Australian family-owned company based on traditional values. 

“We pride ourselves on service, stability and reliability in providing pipeline rehabilitation solutions to our customers.”

CWW secures water supply

As part of the M205 Carlton Water Main Renewal Project, CWW installed a new 750 mm wide water main along Canning Street in Carlton.

CWW General Manager of Infrastructure and Delivery Amanda Smith said the upgrade was vital to ensure reliable water services for the community and its anticipated future growth.  

“The existing water main is almost 140 years old and nearing the end of its service life,” said Ms Smith.

“The new pipe is almost twice the size and will meet the needs of the CBD and inner Melbourne community it serves well into the future.
 
“I’m really grateful to residents and businesses in and around Canning Street who welcomed us into their quiet, leafy neighbourhood and showed great patience while we delivered this significant project.
 
“A small and committed group of community and stakeholder members also joined us on a project Community Reference Group, which allowed us to bring them behind the scenes of the work we were doing and helped us understand how to best plan and deliver these works with minimal disruption.” 

Works were completed on a popular bike commuter route, with CWW planting hundreds of trees and installing new drinking fountains in the area as a thank you to the local community for its support.  

CWW partnered with Jaydo on the infrastructure project, saying it demonstration a “joint commitment to working safely, supporting community safety and putting customers first”.
