Using a Sond

Using a Sond can help you determine the direction of a pipe and where a drain may be blocked.

In the picture below we are using a Sond by feeding a pipe into a broken drain. The pipe has a metal end and this can be detected by the Sond above ground. This is a bit like metal detection or radar.

Sond Drain

If the Sond detects the end of the pipe there is a strong signal. Generally one person feeds in the pipe, and the other marks the route with good communication.  From each mark the pipe is pushed in a little further and from this the line of the pipe can be marked.

If you cannot move the pipe any further, then your options are to suck out any silt or effluent in the pipe, or to dig down at that point. You can then investigate what the precise issue is without making too much of a disturbance.

In this particular situation the owner of the field has found that the drainage on his field is poor. There is black water locating at the bottom of his field. There are 3 homes that drain their old fashioned septic tanks onto the field.

The ground is generally clay. There is therefore no absorption of the effluent into the ground. The drain being in good condition would go someway towards solving the issue.

Through using a Sond you can solve some key drainage issues for less work and disruption.
