Occasionally, boreholes drilled into the chalk aquifer may need to be developed to increase performance or rehabilitated due to blockage by incrustations.
At H.D. Services we utilise three different types of development – airlifting; acidisation and BoreSaver. This page attempts to explain the principals behind them and in which conditions each should be used.
AIRLIFTING: This technique is usually used when debris finds its way into the borehole and results in sediment being pulled through the borehole pumps etc.
ACIDISATION: This technique is used to facilitate the removal of soft material from within a chalk borehole and to open fissures in the chalk by using hydrochloric acid. This process increases the flow rate of the borehole by allowing more water from the aquifer to enter the borehole.
BORESAVER: BoreSaver was developed by Aquabiotics Industrial and is approved for use in private water supplies – including those used for drinking water – by the Secretary of State in the UK.
