90 Foot Well Refurbishment Restoration


We were contacted by a client that had a private water supply from a 90 foot well.  The position of the well was situated directly where he was having a new property constructed.  We were requested to remove the top 2 meter section of the brick well.  As you will see from the photos and video link this was another challenging project for our team, but which we successfully carried out.  Our client had also contacted other pump companies that were unable to assist due to the complex nature of the task, however, we like a challenge.


This was a rather unusual well construction with the top section being 6’ diameter, reducing down to 5’ diameter.  There were also steel bearers every 10’ with the original duplex lift and force pump main and rods in place.  In addition the original cast iron lift and force A frame was manufactured by a company in Walton-on-the-Naze which turn out to be the same company that cast Big Ben.


We also cleaned and deepened the well installing a bore in the bottom increasing the well yield from a minimal flow to approximately Well Refurbishment ECP Group, Ipswich, Suffolk, Essex, Cambridgeshire, East Anglia350gph.  We can safely say that in the past this well has never yielded this quantity of water due to a very fine sand formation, which we term as boiling sand.  Now that we have installed the bore in the well bottom, the sand is no longer boiling in.


The works we carried out enabled us to install a borehole type submersible pump as the bottom of the bore is deeper than the well allowing full access to all the well depth of water.


The pump we installed was an Espa ES40214M on 32mm MDPE corrosion proof rising main.  The borehole was capped off with a special hygienic American made well seal preventing debris entering the borehole. 


The well was finished flush with the ground/basement level using 2inch galvanised pipes as the support bearers.  The builders are to cast a concrete top in with the basement floor.


Once the new house construction has been completed we have to return to site and install all necessary water treatment equipment, this being a Hague Water Softener Condition, Morion Drinking Water System and the Saphir Ultraviolet Water Disinfection System.
