Investigations on site to accurately locate a public sewer will be required. How extensive these are will vary from property to property. We recommend you consult a qualified, capable person, such as an architect, engineer or your builder.
The first thing to do is locate any manhole chambers. These offer a visible sign that a public sewer might run within your property. However, sometimes a manhole may have been covered by vegetation, decking or patio slabs. Even if there are no physical signs of a manhole cover, that doesn’t mean that there isn’t a sewer running below the ground within your property.
Sometimes, a trained and competent individual may need to lift manhole covers to find out more information about the sewer.
As well as locating manhole chambers, we also recommend that you consider an electronic sewer trace or the digging of trial holes to precisely identify the position of the pipework. There are a number of private drainage contractors that offer this service.
