Well Water Supply Running Dry?

Well Restoration New FlowWell Water Supply Running Dry?


We were contacted by a new client, advising they believed their well was running dry.  They had been struggling for weeks using bottled drinking water and a temporary supply from a neighbouring farm.


When I attended site to carry out my risk assessment, I suspected the well bottom was silted up and an attempt had been made to deepen the well at some stage, utilising PVC pipes full of concrete which were resting on the wooden VAT.  (A wooden VAT is a round circular barrel which is driven down approximately 3 feet deeper than the brickwork.  The VAT is water tight which thereby prevents water entering the well below the brick work.  This keeps the soil at the base of the brickwork firm.  Without the VAT or if the VAT is broken, the well bottom becomes fluid allowing the brickwork to sink.  It is imperative that the brickwork does not sink once the well sinking is complete. 


We carried out our well restoration process, firstly removing the debris and silt and then deepening the well with a bore, (those of you that have read our previous blogs may be familiar with the process).  We were surprised at the volume of bricks and concrete that had been thrown into the well over the years.


Whilst de-watering the well, the flow was minimal and the recovery rate extremely slow.  After our well deepening restoration the yield was increased to approximately 1800 gph, (135 lpm) which is an incredible flow with a fantastic recovery rate.  Our client is extremely pleased with the results as we are.


Working Down Well ECP GroupWe also installed a new Saphir 2 Ultraviolet Water Disinfection System (UV) to ensure the water is bacteria free.  Oddly the previous company that looked after the well had removed the Saphir UV and Pre-Filter by ECP GroupUV filter and advised our client, that a UV system would not be required, as a Reverse Osmosis Filter (RO) had been fitted.  This is an alarming comment to have been made and this information is incorrect.  Whilst a RO Filter will reduce many contaminants such as pesticides, herbicides, nitrates etc. it does not destroy bacteria in drinking water supplies.  Only an UV system is capable of destroying bacteria with UV rays.  In addition, only a small drinking water tap is treated with the RO filter.  All other water would be untreated.  Would you consider showering in bacteria laden water; I certainly wouldn’t?


Although the house supply is from the well, all water is treated via the UV and the flow and pressure equal to or better than a mains supply. 


Finally, water levels in wells and boreholes have dropped approximately 60cm due to the recent hot summer of 2018, and relatively low rainfall over the past few years.  Wells and boreholes rely on steady prolonged rainfall to replenish the aquifer, so each time it rains just think of the benefits rather than the irritation.


If you have a well supply that is running low, or suffering with low water pressure, then contact us for assistance.
