Frequently Asked Questions
Q: What is a geological survey?
At the start of the process of finding a sustainable water supply on your land we need to determine what the likelihood is of finding water. There are several tools which we can use to assist in this process. Firstly, we look for existing boreholes in your area.
We consult geological maps for known strata character for your area. This gives us a very general view of the current ground water situation. For your interest, an antique map dating from 1860 may be viewed here.
We then consult the British Geological Survey to find other wells or boreholes which may exist within your locality and try to determine what yield these may be producing.
Assuming that other sources exist, we are then be in a better position to advise you of the quality and quantity of water you may expect to find.
Q: When should this survey be performed?
The survey should be the first step in the process. In the unlikely event that your area is poor in natural ground water, the survey process will prevent further unecessary costs to you.
Example: We recently attended a client who had already drilled a bore hole to 100 metes at considerable expense. Unfortunately his borehole despite being very deep, produced no appreciable volumes of water. This bore was essentially useless for his purposes. Whilst scenarios such as this are rare, they do happen so having the survey done before could have saved them thousands of pounds.
Q: How will a geological survey help me?
The object of the survey exercise is to provide you with some sort of visual as to what the land beneath your feet has in terms of not only water but the sustainability and quality of it. The geological survey helps to make you better informed as to whether or not any considerable capital investment is going to be worthwhile.
Q: What else can i do before drilling?
There is another step which you can do before going ahead and spending a lot of money on drilling a borehole. This is using a dowser to get an accurate location to put the drill head to start drilling. You may have loads of water beneath you but if you miss it you have wasted a lot of money.
