Commercial Water well for Dairy Farm
We were contacted by a South West dairy farmer running a herd of 3000 cows. He had previously used another driller in an attempt to reduce his eye watering mains water bill. They had been unsuccessful in finding a usable supply in any of the 5 boreholes that had been drilled around the farm.
As the client had commissioned a basic borehole prognosis report in the past he provided us with the information and asked us to advise and quote accordingly. The geology of the area consists of Clay and Mudstone and needs to be drilled in a specific way to prevent the drill cuttings smearing the sides of the borehole and preventing water entering the borehole.
We mobilised a rotary rig to site and drilled a 40M deep borehole, as deeper drilling in the area can encounter Saline water. The borehole was lined and packed before a full bentonite seal was installed to protect the aquifer from surface contamination.Pump testing proved a yield of 4,500L/Hr which is being used to supply the plate cooler/heat exchanger.
A full Hydrogeological report is now being prepared to explore the viability of multiple boreholes being drilled at the site to provide a larger supply as the client already has an abstraction license which allows him to take more than the 20,000L/day limit.
