The Water Act of 2003 (see below) states that domestic users may daily extract up to 20 cubic meters, 20 000 litres, 4400 gallons of ground water, without any permission being required. No charge. No fee.
27) Rights to abstract small quantities
The restriction on abstraction shall not apply to any abstraction of a quantity of water not exceeding twenty cubic metres in any period of twenty-four hours, if the abstraction does not form part of a continuous operation, or of a series of operations, by which a quantity of water which, in aggregate, is more than twenty cubic metres is abstracted during the period.
