Drain Tracing
 Sometimes it is difficult to work out exactly in which direction a drain is running. In order to establish this we offer a drain tracing service to locate underground pipe work and detect structural defects. A sonar-emitting transmitter is fed into the drain. Above ground, a sensor is used to monitor the progress of the transmitter. We can even determine directional and depth readings.
We use the service to show builders where not to dig foundations, to prove connections to main sewers and even locate septic tanks.
