How big does my borehole need to be?

A normal domestic borehole usually has a maximum finished diameter of 150mm although boreholes with a finished diameter of 100 or 125mm can be used with certain ground conditions to accommodate a 100mm outside diameter pump and cable. The average depth of a domestic borehole is between 40 and 70 metres depending on the hydrogeological conditions encountered
