Need to find out where a drain goes? We have the answer. A module containing a transmitter is introduced into the pipe using rods. As the transmitter is pushed along the pipe, a hand held receiver then picks up the transmitted signal and pinpoints the position of the pipe. The equipment will function at depths up to 15 metres, dependant on underground conditions. The equipment does not function in metallic pipes.
This application will be of particular interest to construction companies developing sites with existing drainage. Sonar tracing used in conjunction with CCTV can positively identify the source, condition and route of existing drains. With this information, considerable amounts of money could be saved by using the existing drainage in preference to laying new pipes.
This process can save hours and, in some cases, days of endless digging and looking for hidden and hard to trace drains.
