Water boreholes are deep narrow wells that tap into our naturally occurring underground water.A high efficiency pump brings it to the surface from the permeable rock below.In most cases,a borehole well is usually the safest source of drinking water available.Most deep ground water entered the ground hundreds or even thousands of years ago before there were many man made chemicals around. There are some things to note in having a borehole water.. (1) Where to drill-Once the decision has been taken to drill a borehole.The drilling site has to be chosen and this is done via a geophysical survey in order to probe beneath the surface to know the geoelectric layers like, topsoil,weathered basement/fractured basement, fresh bedrock,lithological contact zones.(2) when to drill-If you are building a house,the well should be put amongst first things to do.Your building contractor will need water for numbers of things during construction.But if you have already have your home built,It is no big deal.(3)Drilling-Borehole depths vary dramatically from area to area.From as little as 36m deep to as deep as 250m depending on the survey report,location and customers requirement.The rest is to install a submersible pump which will pump the water from the source to your tank..I think this write up will be helpful to someone....08069641878(watsapp) 09050615685 call
