Mine site and mine camp drainage systems often run beneath roads, buildings and operational areas, making it difficult to identify the cause of a blockage or recurring fault from the surface. Tunnel Vision helps mining operators investigate underground pipe conditions through targeted drainage inspection, cleaning and rehabilitation services, reducing unnecessary digging and guesswork.
Our guide aims to help explain what CCTV drain inspections reveal across mine sites and camps, including blockages, sediment build-up, tree root intrusion, damaged joints, corrosion and collapsed pipe sections, while discovering how clear CCTV footage supports more informed decisions about drain cleaning, pipe relining, targeted excavation and replacement.
A professional CCTV drain inspection uses a specialised waterproof pipe inspection camera to examine the inside of sewer, wastewater and stormwater pipes. On a mine site or at a mine camp, this provides a clear view of underground infrastructure that may run beneath roads, accommodation buildings, workshops and operational areas.
The inspection process generally involves:
The footage may also be used to document the pipe condition and support discussions between mine operators, asset owners, maintenance teams and civil contractors. Rather than relying on surface symptoms, they can use the inspection findings to plan cleaning, further investigation or targeted repairs.
Surface symptoms such as slow drainage, overflows and recurring blockages do not always show where a problem is located or how serious it has become. As with drain inspections, a sewer inspection camera provides recorded footage that provides a direct view of defects and obstructions inside the pipe.
Sediment, sludge, grease, construction debris and foreign materials can restrict the available pipe diameter and reduce flow. A CCTV inspection shows where the obstruction begins, how far it extends and whether water is collecting behind it.
At mine camps, blocked drains can affect kitchens, laundries, accommodation buildings and ablution facilities. On operational mine sites, sediment and heavy debris may also enter external drainage lines during construction, earthworks or periods of heavy rainfall.
The camera footage may reveal small cracks, fractures, holes and broken sections along the pipe wall. These defects can allow wastewater to escape or surrounding soil and groundwater to enter the drainage system.
Recording the location and visible extent of the damage helps maintenance teams determine whether the defect appears isolated or forms part of broader deterioration across the pipeline.
Ground movement, ageing materials and installation issues can cause underground pipes to deform or collapse. A partial collapse may restrict flow and contribute to repeated blockages, while a complete collapse may prevent the camera from travelling further through the line.
Our guide to the warning signs of a collapsed sewer pipe provides further information about the drainage symptoms that may indicate structural failure.
CCTV footage helps narrow down where the collapse has occurred, reducing the amount of unnecessary excavation required if the damaged section needs to be accessed or replaced.
Tree roots can enter underground pipes through tiny cracks, loose joints and damaged lateral connections. Once inside, the roots continue to grow and form a mass that catches waste, sediment and other debris.
This may be particularly relevant around established mine camp landscaping and accommodation areas. Learning more about tree roots in pipes can explain how CCTV footage can document the location and extent of root intrusion.
Ground movement or installation faults may cause connected pipe sections to move out of alignment. The camera can identify offset joints, gaps and lateral connections that no longer meet correctly.
These defects may interrupt flow, trap debris or create openings through which soil, groundwater and tree roots enter the pipe network.
Older metal pipes may show signs of corrosion, scaling or pitting along the internal surface. Concrete, clay and other materials can also crack, erode or deteriorate over time.
CCTV footage does not replace every form of structural assessment, but it provides useful visual evidence of pipe condition and highlights sections that may require closer investigation.
Standing water can indicate sediment build-up, pipe deformation, a downstream blockage or an issue with the drainage fall. Watching where the water begins to collect helps the inspection team identify which nearby defects may be contributing to poor flow.
CCTV inspections can also be used to assess stormwater drains affected by sediment, debris, root intrusion or damaged pipe sections.
Together, these findings give mine operators a clearer understanding of what is happening inside the pipe network. Instead of responding only to visible symptoms, maintenance teams can prioritise the affected areas and plan the next step using recorded evidence.
Finding a defect is only the first step. The CCTV footage also helps mine operators understand its location, apparent severity and the length of pipe affected, making it easier to select a targeted response instead of treating the entire drainage network as one problem.
Tunnel Vision used this inspection-led approach during its UV pipe relining project, where CCTV footage identified severe root intrusion in a stormwater main before cleaning and trenchless rehabilitation were completed. A post-installation inspection then confirmed the condition of the finished liner.
The appropriate response depends on the pipe diameter, material, access, location and severity of the defect. CCTV drainage inspection footage provides the evidence needed to compare these options and prioritise work across the site.
A CCTV inspection does not need to be limited to emergency callouts. Mine operators can also use recorded footage to monitor underground assets, investigate recurring issues and plan maintenance before a drainage problem disrupts site operations.
An inspection may be appropriate:
Mine camps may also require an inspection when drainage problems affect several accommodation buildings, kitchens, laundries or ablution facilities. A camera can help determine whether the issue is isolated to one connection or located deeper within the shared sewer network.
Including CCTV inspections within a broader mining drainage and pipeline maintenance program gives asset owners a clearer record of underground pipe conditions. This makes it easier to prioritise defects, coordinate contractors and plan work around operational requirements rather than waiting for a major failure.
Underground drainage issues can be difficult to diagnose from surface symptoms alone. CCTV footage gives mine operators, maintenance teams and asset owners a clearer view of pipe conditions before cleaning, rehabilitation or excavation work begins.
Tunnel Vision supports mining and industrial clients with CCTV drain inspections for sewer, stormwater and wastewater infrastructure. The team can assess access points, pipe dimensions and reported drainage issues before recommending an appropriate inspection approach.
Contact Tunnel Vision to discuss your site requirements and arrange an inspection of the affected sewer, stormwater or wastewater infrastructure.
There is no fixed timeframe. It depends on the pipe diameter, access points, pipe network size and whether heavy debris, standing water or construction debris slows the inspection.
Not always. High-pressure water jetting may be required if blocked drains, tree roots or sediment prevent the waterproof camera from clearly showing the pipe condition.
Not every pipe can be inspected with the same equipment. A push rod camera may suit smaller underground pipes, while larger stormwater systems may require different CCTV technology and access points.
CCTV footage helps locate a collapsed sewer line, broken pipe or joint failure. Asset owners and civil contractors can then plan targeted excavation or pipe replacement without unnecessary digging.
Not on its own. The camera inspection can detect cracks, pipe corrosion, root intrusion, misaligned joints and structural weaknesses, but the final repair may involve drain cleaning, trenchless pipe relining, targeted excavation or replacement.
