Maintaining underground infrastructure is essential for protecting communities, preserving assets and ensuring effective stormwater management. At M. Tucker & Sons, we specialise in delivering innovative trenchless rehabilitation solutions that extend the life of ageing pipe networks while minimising disruption to residents and the environment.
One of our latest projects sees our Civil Trenchless Solutions team undertaking a major stormwater pipe relining project within the Lilydale Lakes Estate on behalf of Yarra Ranges Council.
Over a six-week period, our team is relining approximately 1,250 metres of ageing stormwater pipeline using advanced UV-cured CIPP (Cured-In-Place Pipe) technology. By rehabilitating the existing network rather than excavating and replacing the pipes, we are helping Yarra Ranges Council restore critical infrastructure while avoiding the significant costs and disruption associated with traditional pipe replacement methods.
This project highlights the growing importance of trenchless technology in modern infrastructure maintenance and demonstrates why pipe relining has become the preferred solution for councils across Victoria.
Stormwater systems play a vital role in managing rainfall runoff and protecting homes, roads, parks and public infrastructure from flooding.
Many underground stormwater networks throughout Melbourne and regional Victoria were installed decades ago and are now reaching the point where deterioration begins to affect performance.
Common issues include:
If left untreated, these problems can eventually lead to pipe collapse, flooding, environmental damage and costly emergency repairs.
The stormwater network within Lilydale Lakes Estate is no exception. Over time, sections of the pipeline had experienced deterioration that required rehabilitation to ensure the system continues to perform reliably for the local community.
Rather than excavating and replacing the damaged pipes, Yarra Ranges Council selected UV pipe relining as a cost-effective and sustainable long-term solution.
Stormwater pipe relining is a trenchless rehabilitation method that restores the structural integrity of an existing pipeline from within.
Instead of digging up and replacing the old pipe, a specially designed liner is inserted into the existing asset and cured in place to create a new pipe within the old pipe.
This approach provides numerous advantages over traditional open-cut replacement methods.
Benefits include:
Pipe relining has become one of the most widely used rehabilitation techniques for stormwater, sewer and drainage infrastructure throughout Australia.
The current works involve the rehabilitation of approximately 1,250 metres of stormwater pipeline throughout the Lilydale Lakes Estate area.
The project is expected to take approximately six weeks to complete and forms part of Yarra Ranges Council’s ongoing commitment to maintaining and improving critical community infrastructure.
Our team is working systematically through the network to identify, prepare and rehabilitate sections of damaged pipe.
Each section undergoes a detailed process that includes:
Before relining begins, the pipe network is thoroughly inspected using specialised CCTV equipment.
This inspection allows our team to:
Detailed condition assessments ensure the most appropriate rehabilitation approach is selected for each section of pipeline.
Before a liner can be installed, the pipe must be thoroughly cleaned.
This process removes:
Cleaning ensures the liner can achieve maximum adhesion and structural performance once installed.
Once prepared, the pipe is ready for rehabilitation using advanced Impreg UV CIPP liner technology.
The liner is carefully inserted into the existing pipe and positioned accurately throughout the rehabilitation section.
A specialised UV curing system is then used to activate the resin and create a fully structural pipe within the existing pipeline.
The result is a seamless, joint-free pipe that restores structural performance and hydraulic efficiency.
At M. Tucker & Sons, we utilise Impreg UV CIPP liners because they provide exceptional structural performance and long-term reliability.
The Impreg liner system is recognised globally for its quality, consistency and durability.
One of the most significant benefits is its impressive design life.
The Impreg UV liner installed throughout the Lilydale Lakes Estate project has a design life of approximately 100 years.
This means Yarra Ranges Council is not simply repairing damaged pipes.
They are effectively creating a long-term infrastructure solution that will continue serving the community for generations.
The extended lifespan delivers substantial value for ratepayers by reducing future maintenance and replacement costs.
One of the primary objectives of pipe relining is restoring the structural performance of ageing pipelines.
As stormwater pipes deteriorate over time, cracks, fractures and joint failures can compromise their ability to withstand surrounding soil loads and groundwater pressures.
The cured liner creates a new structural pipe inside the existing pipe.
Benefits include:
Once cured, the liner effectively becomes a new pipe while utilising the existing pipeline as a host structure.
Tree root intrusion is one of the most common causes of stormwater pipe deterioration.
Roots naturally seek out moisture and often enter pipelines through cracked joints or damaged sections.
Once inside the pipe, roots continue growing and can eventually cause:
The UV-cured liner creates a continuous, joint-free internal pipe surface.
Without joints or openings, roots can no longer enter the pipeline.
This significantly reduces future maintenance requirements and helps ensure reliable long-term performance.
A common misconception is that pipe relining significantly reduces pipe capacity.
In reality, modern UV liner technology is designed to maximise flow performance while providing structural rehabilitation.
Although a liner is installed inside the existing pipe, the smooth internal surface often improves hydraulic efficiency compared to the original deteriorated pipe.
The relined pipes within Lilydale Lakes Estate will be restored to approximately 93% of their original capacity.
This is achieved without excavation and while providing a completely new structural lining system.
The improved flow characteristics help maintain effective stormwater management throughout the estate.
Traditional pipe replacement often requires significant excavation activities.
This can involve:
For residential communities such as Lilydale Lakes Estate, these impacts can be substantial.
Pipe relining dramatically reduces disruption because the majority of works are completed through existing maintenance access points.
Residents experience fewer disruptions while council infrastructure remains operational throughout much of the rehabilitation process.
Sustainability is becoming increasingly important in modern infrastructure management.
Pipe relining provides several environmental benefits when compared with traditional replacement methods.
These include:
Less excavation means reduced disturbance to surrounding vegetation, ecosystems and landscapes.
The existing pipeline remains in place, significantly reducing construction waste sent to landfill.
Reduced excavation, transport and material requirements help lower the project’s overall carbon footprint.
Roads, footpaths, parks and landscaping can remain largely untouched throughout the rehabilitation process.
For councils seeking sustainable infrastructure solutions, pipe relining offers significant environmental advantages.
Local councils manage extensive underground infrastructure networks that require ongoing maintenance and rehabilitation.
Proactive projects such as the Lilydale Lakes Estate stormwater relining program help prevent future failures while ensuring infrastructure continues performing efficiently.
Through strategic rehabilitation programs, councils can:
