Bacchus Marsh network upgrades complete

The $20 million works include an upgraded sewer pump station, a new sewer pipeline and two new water pipelines with most of the projects completed in the past month. 

GWW General Manager Growth and Infrastructure Amanda Smith said with the local population projected to double to 46,000 in the next 20 years, this investment will ensure the network can meet demands for services for many years to come. 

“It ensures GWW can meet the demand for sewerage services for at least the next 15 years,” said Ms Smith.

“These projects have been safely delivered under COVIDSafe settings, demonstrating the concerted efforts of staff and contractors.”

Works included $6.7 million upgrade to the Grant Street Sewer Pump Station, $9.2 million in 8 km of sewer pipeline from Peelmans Lane to the Bacchus Marsh Recycled Water Plant, and $3.4 million on a duplicate sewer pipeline from Holts Lane to the Avenue of Honour.

These are only a few of the major projects that have been under development and construction across the service area.

Byron Bay plans $1.4m network upgrade

The Byron Shire Council has provided a $1.4 million grant from the Australian Government’s Local Roads and Community Infrastructure Program to upgrade Byron Bay’s stormwater drainage network.  

The network covers across Lighthouse Road, Paterson Street and Kipling Street.  

“We are very excited to be delivering these critical works, which include the construction of kerb and gutter and underground stormwater drainage on Lighthouse Road,” said Byron Shire Council Director of Infrastructure Services Phil Holloway. 

These works will reduce stormwater runoff that currently impacts Clarkes Beach, mitigating the impact to the environment.  

Mr Holloway said that once upgraded, the stormwater network will capture, detain and that runoff from the roads and surrounding properties.  

The works are commencing on 9 August and are expected to take four months to complete.

Primus Line breathes new life into historic trunk main in Brisbane

Earlier this year, Urban Utilities completed a multi-million-dollar rehabilitation project on this 130-year-old pipeline.

With the use of the trenchless technology Primus Line®, the project is expected to extend the life of the pipeline by at least 50 years, providing an economical solution with minimal impacts to traffic and nearby businesses and residents. 

The Ann Street pipeline is a cement-lined, cast iron pipe, and helps to supply water to the city centre and the inner-city suburbs.

During the morning and evening peak consumption periods, about 500 L of water per second flows through the pipe. 

Thousands of vehicles a day roll along the four-lane road, which is one of the busiest roads in Brisbane’s central business district, and businesses and bus stops line the traffic route. 

Replacing water mains in heavily congested urban environments can be a costly and disruptive process, so in this case trenchless technology was the key to success.

Given the location of the pipe, Primus Line was chosen as it could pass through several bends in the pipe and be installed using a few small pits, to minimise the impact on traffic. 


As Primus Line is a flexible stand-alone pipeline, which is installed with an annulus gap, it can withstand the operating pressures of the water main, but not the external loads from the traffic on the road above. 

The project at Ann Street was preceded by a detailed condition assessment of the host pipe and economic evaluation in order to ensure the existing pipeline could withstand external loads in the future.

The results showed that the pipeline had sufficient load bearing capacity to allow the use of a semi-structural lining system such as Primus Line for the desired service life of at least 50 years. 

The perfect choice 

Due to its unique three-layer structure, the Primus Liner combines flexibility with extremely high material strength.

As a self-supporting pressure pipe liner independent of the old pipe, it absorbs the entire operating pressure, while the old pipe merely functions as a conduit. 

In accordance with ISO 11295, Primus Line is an independent pressure pipe liner capable on its own of resisting without failure all internal loads throughout its design life.

It has the ability to negotiate bends of up to 45 degrees, allows for seasonal movement of the pipeline and ensures the required operating pressure of up to 11.3 bar. 

Despite the reduction in cross-section of the DN 600 pipe, flow calculations showed the client that the installation of a Primus Line DN 500, with its low friction coefficient of only 0.028, would still provide the required flow. 

Before the start of the project, a large- scale trial with a length of 350 m was carried out with the Primus Line system – developed and produced in Germany.

In a single day, the pre-folded liner was pulled into the 350 m field trial section of the Ann Street trunk main, formed into its circular shape with compressed air and successfully connected to the pipeline network.

Start of the major project 

The successful completion of the trial allowed for the commencement of the Ann Street project, where detailed design and construction planning was performed in 2019 by Urban Utilities.

Small excavations are
sufficient for the installation.

The initial stages of the project also involved cleaning and prepping the existing pipe to make it suitable for installing the liner, while the installation phase began in mid-2020 and was completed in early 2021. 

Most of the work took place at night and the small construction pits were closed during the day with large steel plates, to allow traffic to continue to flow.

The entire project was carried out by Urban Utilities’ own workforce, and the company had previously installed Primus Line on other rehabilitation projects in its service region. 

Urban Utilities had engaged Primus Line to provide training to its team, and kept the required necessary tools and spare parts in stock to perform Primus Line installations and possible repairs and maintenance in-house. 

The Primus Line team provided engineering support and accompanied the beginning of the measure with a supervisor.

Four installation sections were necessary to rehabilitate the 2.2 km long pipeline section, with the Primus Line system DN 500 PN 16 used to rehabilitate the DN 600 water pipeline.

Primus Line delivered the four liner sections pre-folded in a U-shape and wound onto drums.

The liner insertion into the old pipe was done with a winch and in the process passed through some additional smaller intermedia pits to reinstate valves and offtakes.

The liner was pulled through these pits and cut afterwards to install the Primus Line connectors and the necessary valves and t-pieces 

Special DN 500 connectors with a DN 600 flange were used to ensure the connection to the flange on the host pipe while keeping the pits as small as possible. 

A pressure test concluded the successful installation before the main was disinfected and returned to operation.

Quick-Lock remains key to pipe repair

For structural, trenchless pipe repair, the company offers the Quick-Lock solution.

The Quick-Lock system has revolutionised sewer rehabilitation through its wide range of applications and strong reliability.

Using heavy-gauge 316 stainless steel with infiltration abatement with an EPDM rubber gasket, the Quick-Lock system seals and stabilises damage completely by mechanical means, removing the need for chemicals and making it suitable for all pipe materials.

The patented locking system ensures that the sleeve stays permanently in position and, after rehabilitation, the sleeve has its own static capability and absorbs the natural tectonic movements of the pipe. 

The system can be used for standalone permanent point repair, or for pre-lining stabilisation works including high groundwater infiltration.

Quick-Lock sleeves restore a pipe’s structural integrity and seal out groundwater, and they are carefully designed to minimise diameter loss and outlast any other rehab.

For larger pipes, SECA offers the Quick-Lock BIG sleeve, which permanently seals leaking pipe joints, radial cracks, and longitudinal cracks in large pipes and manholes of DN800 and larger.

The BIG sleeves are 20 cm wide, and the system is made from V4A stainless steel of grade 1.4404 (AISI 316L) and an EPDM compression seal. 

These materials are permanently resistant in municipal wastewater systems, while their suitability must be ascertained for use in industrial or polluted wastewater.

Out in the field

SureSearch has more than 20 years of operating experience as a company, providing all aspects of utility investigative works, including location, non-destructive excavation, utility survey, mapping and clash detection, CCTV inspections, drain cleaning and pipe rehabilitation offers. 

SureSearch Sales and Development Manager Calyn Wilkinson said the company was relatively new to the pipe rehabilitation sector and felt using the Quick-Lock system was a good way of entering the market. 

“SureSearch has used the Quick-Lock system for both sewer and storm water rehabilitation,” he said. 

“It has been used for sealing joints, holes and also infiltration through cracks.

“Due to the fast installation time and no curing of material, it has a great advantage over the cured-in-place pipe (CIPP) method. 

“More installations can be achieved in a shift and if traffic control is required then this limits the amount of money spent on traffic control shifts.”

Quick-Lock end caps strengthen a CIPP liner at its most vulnerable points—the ends.

This mechanical solution prevents liner and host pipe infiltration or exfiltration for the lifetime of a close fit liner. 

It is particularly most effective on EX, spiral, and UV cured liners, and it is stronger and easier to install than other end caps, making them highly beneficial on any long-term watertight lining project.

Quick-Lock systems can be purchased from SECA’s warehouses or from SECA’s nationwide sales representatives.

Watercare outlines NZ$18.5b plan

Earlier this month, the company released its Asset Management Plan (2021-2041) which outlines how Watercare will deliver new water sources and infrastructure, as well as renew and expand its wastewater network, to cater for Auckland’s expanding population.

The city is anticipated to have approximately 476,000 more residents over the coming 20 years and Watercare Chief Executive Jon Lamonte said it was important to continue to support the changes in a climate-resilient way.

“We have a colossal job to do to ensure we can continue to provide top quality drinking water to all of our customers and safely treat our region’s wastewater while adapting to the changing climate.
“While our population grows, industry does too,” he said.

“Auckland is already home to two-thirds of the country’s food and beverage manufacturers – two sectors for which water is vital – so ensuring we can support growth in these industries with a secure water supply is important for the wider economy.”

Mr Lamonte said the total investment averaged out to NZ$2.5 million ($2.37 million) per day, and there was no shortage of work to undertake.

“If consent is granted, we plan to progressively expand our new treatment plant near Tuakau until it can treat up to 150 million L a day.

“To put that volume in perspective, that’s more than what we can get from all five of our Waitākere dams,” he said.

“We’ll also need a new pipeline to carry this water to the city and increase our system’s resilience.”
