Pipe Management Australia (PMA) was engaged to clean and inspect critical stormwater culverts across an active coastal foreshore. The works restored tidal flow through sand-blocked culverts and captured CCTV condition data to support the client's forward maintenance planning.
Industry: Stormwater & Coastal Infrastructure
Project Type: Culvert Cleaning & CCTV Inspection
PMA's crews removed more than 40 tonnes of accumulated sand from three culverts for a valued client in NSW.
Our MicroTraxx culvert cleaning unit, CCTV inspection units and a grab truck worked in sequence with tidal windows to maximise productive hours on site.
A total of 40 metres of culvert were inspected using CCTV technology to assess internal structural condition and support future maintenance planning.
Originally scheduled over three days, the project was successfully completed in just two days through efficient operational planning, coordinated resource deployment, and strong safety and environmental management practices in a highly active public environment.
PMA was selected for its expertise in stormwater asset maintenance, confined space operations, and CCTV condition assessment services in challenging coastal environments.
The project required a contractor capable of safely operating within tidal zones while maintaining public access and minimising disruption to pedestrians and traffic.
As the sole operator of Australia’s only MicroTraxx remote controlled culvert cleaning units, PMA was uniquely positioned to be able to clean these culverts without manned entry or the use of potable water for cleaning.
PMA’s ability to integrate cleaning, inspection, traffic management, and environmental restoration into a single coordinated operation ensured the efficient delivery of the works.
Delivering the works within an active coastal environment presented several operational challenges.
Tidal movements significantly impacted site accessibility and available working hours. Crews operated within strict tidal windows, requiring increased labour resources and equipment coordination to maximise productivity during limited access periods.
Vehicle movements and equipment staging areas were carefully managed due to restricted access conditions. All vehicles were required to park within designated areas to minimise disruption to local traffic and surrounding public spaces.
The foreshore attracts significant pedestrian traffic including walkers, runners, and beach visitors. Maintaining public safety while ensuring operational efficiency required secure work zones, clear traffic management measures, and ongoing site monitoring throughout the project duration.
To successfully deliver the project, PMA implemented a coordinated cleaning and inspection methodology tailored to the coastal environment.
Using the MicroTraxx, CCTV inspection equipment, and grab truck, crews cleaned and opened blocked culverts before conducting detailed internal inspections to assess structural condition and identify any defects or maintenance concerns.
The works were carried out by four PMA crew members and an onsite supervisor who coordinated daily operations, tidal access scheduling, safety procedures, and traffic management requirements to maintain productivity within restricted working windows.
Traffic control measures were implemented to safely manage pedestrian movement around active work zones and maintain safe public access pathways throughout the works.
By sequencing works around tidal movements and deploying additional labour and equipment during critical access periods, PMA maintained productivity and delivered the project ahead of schedule.
In addition to restoring culvert functionality and completing CCTV inspections, PMA delivered broader operational and environmental benefits through proactive planning and efficient site coordination.
The project successfully reopened tidal flow pathways, improving water movement through the stormwater system while providing valuable condition data to support future maintenance and asset management decisions.
Combining cleaning, inspection and environmental restoration within a single mobilisation reduced public disruption and streamlined delivery.
Key project outcomes included:
The completed works improve the ongoing performance and resilience of critical stormwater infrastructure within the Sydney foreshore area.
Restoring culvert functionality and tidal flow supports improved drainage performance and helps reduce the risk of future blockages or water movement issues. The CCTV inspection data also provides valuable condition intelligence to support future maintenance planning and early identification of structural concerns.
For the local community, the project was delivered with strong consideration for public safety and environmental outcomes. Coordinated traffic management and secure work zones minimised disruption to pedestrians and surrounding public areas, while sand replacement activities reduced environmental impact on the beach environment.
