The Water Act of 2003 (see below) states that domestic users may daily extract up to 20 cubic meters, 20 000 litres, 4400 gallons or, in metered form, about £20 worth per day of ground water, without any permission being required. No charge. No fee.

A well utilized water borehole will pay for itself in a couple of years.

Pure water. No chemicals. No wastage. No hosepipe ban!
