An independent hydrogeological survey (a prognosis) is an essential requirement before any drilling commences. The survey provides an indication of the underlying hydrogeology – detailing the nature of the ground to be drilled, the likely depth at which water will be found and an indication of water quality, enabling the borehole design to be properly specified. Whilst the prognosis is not a guarantee of success it will highlight any risk at an early stage.
Water or heat?
The requirements for water and for heating boreholes are in many respects different, and will require a specific form of prognosis:
- A prognosis for water is concerned with the availability, quality and quantity of water
Water borehole prognosis
Basic report: Encompassed geological sequence, expected depth of borehole, water quality testing and % chance of finding water = £240.00 incl. VAT
Enhanced prognosis: Particularly for commercial installations, further information may be required. Detailed report encompassing geological sequence, target aquifer, expected depth of borehole, water quality testing, % chance of finding water, drilling conditions, basic design in schematic form, schematic of underlying geology, site map and copies of publicly available records of any nearby boreholes or wells that have been lodged with the British Geological Survey.
The cost of a water prognosis is based on the volume of water to be abstracted.
- Under 20m3/day = £600.00 incl. VAT
- 20m3 to100m3/day = £720.00 incl. VAT
- Over 100m3/day Price on application – Call FREEPHONE 0800 542 7613 to arrange a prognosis
