clean water inspection camera

Clean-water Only Inspection Camera

We run a range of cameras from push rod cameras for the smaller surveys to a range of on-board tractor cameras for the larger diameter pipes. We offer full pipe surveys which are detailed and edited to suit the customer needs. Each camera is chlorinated and is able to be inserted inside a water main which has only a short time span to be decommissioned.

Digital video for high definition image display, recording and playback

○ Simple transfer of video images to PC for inclusion in customer reports

○ Interchangeable camera options with bright white LED lighting

○ Range of rods and reels—from 100’ to 500’ (30m to 250m)

○  Full compatibility of all cameras, reels and accessories across the range

○  Fully locatable with range of sound options

○ Variety of skids and springs for maneuverability in pipe

○ Audio input for voice over annotation

○ Keyboard option for easier titling of customer survey video and images

○ Rod counter with calibration feature

○ Option to use your own video recording device using video-out/in connector

This camera is only used on clean water jobs and does not be used on any others.  It is kept in a hygienic environment and is treated with chlorine to be fit to be used on human consumption water pipes.  We are one of the only companies who can guarantee a clean water camera and reel.



The mouse is a self-contained transmitter which is connected to a push rod and inserted into a non-metallic pipe or duct structure. The mouse can then be detected using the CAT.



A self-contained flexible rod and transmitter alternative for tracing non-metallic pipes. Energized by connecting to the Genny’ . The small diameter transmitting head allows access to very small diameter pipes of 15mm or above.

PWG pipe locating system

PWG Pipe Locating System

The PWG pipe locating system consists of a receiver (geophone) with an electronic pulse wave generator PWG to be screwed on to a pipe line or hydrant.  The system allows locating non-metal pipes running up to 5 meters below the surface.  The pipe section does not need to be shut down during the locating process.

The waves generated by the device travel best on an even ground structure and ground surface.  Under good conditions, distances of between 50 meters and 600 meters can be covered.  The PulseWaveGenerator system can help to draft, amend, or check network plans, and it can be used both inside and outside residential areas.  Also unknown pipes can be located quickly and reliably with this system.

The geophone (receiver) records the strongest wave on the pipe through a ground microphone and displays their intensity acoustically and optically.

The PWG (pulse generating device) is attached to a water pipeline.  The PWG valve then opens and closes about 60 times per minute due to the water pressure and the flux.  This relief-pressure alternation process generates pulse waves which travel on the pipe as one-dimensional longitudinal compression waves.  These waves are then measured with the geophone on the surface.
