How much would my water well cost?
In the first instance please contact us for a free quotation, or simply a general chat. The cost will depend on the hydro-geology at the site and the access and working area.
Will the well ever dry up?
For domestic water supply boreholes we usually drill 25 metres below the water table or through the full depth of the aquifer.
How do I get a hydro-geological Report on my site?
A prognosis can be obtained from the British Geological Survey (BGS) at Wallingford, telephone 01491 838 800. The current cost of a BGS repost is about £250 and is available in about 6-8 weeks. Before going to this expense however, if we have the relevant records we will be able to advise upon the hydro-geology without charge.
What do I get in a BGS Prognosis?
The BGS report will give an appraisal of the likely geological formation underlying the site. It will also refer to boreholes in the area with an indication of borehole depth, water level, yield and the aquifer penetrated; plus suggest a recommended borehole depth and diameter.
Is the quality and quantity of water guaranteed?
Some aquifers are better documented than others; the chalk for example will generally give plentiful supplies of ‘hard’ water whereas the river gravels along the Thames will generally give plentiful supplies of water that is high in iron. Sand holes are less prolific and can provide softer water that is also high in iron.
What about borehole contamination?
All of our installations are fitted with sealed bolt-on covers, usually situated within an underground chamber, with the permanent lining tubes grouted into place.
Do I need a licence for my own well?
Not unless you intend to abstract more than 20m per day. A family of five will discharge 1m per day into the foul drain runs and hence an abstraction rate in excess of 20m is highly unlikely.
How long does the whole process take?
This again will depend upon the hydro-geology at the site. Including for installation of the borehole pump and pressurised water system, anything from 1 week to two months is usual.
What type of rig would be used?
We drill using percussive techniques, which is the method preferred by the Environment Agency when drilling water supply boreholes as there are no additives used in the drilling process and the drilling action ‘swabs’ the borehole
Is the water potable?
All water can be made potable by treatment, however this will have a cost implication, the extent of which will depend upon the amount of treatment required. The local Environmental Health Office is likely to recommend ultra-violet filtration irrespective of the results of analyses, as contaminants could be introduced to any aquifer several miles away.
