How I work
To understand the underground structure of the area, I use specialised maps, of several different types: geological, hydro-geological and hydrological. Before dowsing, I also consult archived borehole reports of the geology and hydro-geology. The reports are based on data from the British Geological Survey and contain some of the best data in the world.
I then use dowsing techniques to locate sources of water. These will usually be springs or aquifers, but sometimes are old wells, which hopefully can be brought back into use. Wherever possible, I do this on site; occasionally I have to dowse from the map. This technique is generally not as effective, but can still produce very good results.
I find the trajectory of the underground stream and give indications of how much water there is, and how deep down it is. This is very useful when the driller is estimating the costs.
If possible, I suggest several drilling locations. I discuss them with you to identify which is the best, taking all necessary factors into account. For example, the strongest flow may be under a prized ornamental garden, or far enough away from the water usage point to require significant lengths of trenching and piping.
I agree the costs and scope of my services with you before dowsing, and follow up with written reports, readings, descriptions and precise drill-point locations.
