The appellants were irrigation farmers who were members of the Impala Water Users Association, a water management institution established under Chapter 8 of the National Water Act 36 of 1998. The association imposed water use charges on its members for the 2002/2003 year, including a substantial component relating to the construction, operation and maintenance of the Paris-Bivane Dam. When several members failed to pay these charges, the association followed the procedure in s 59(3) and (4) of the Act by giving notice and an opportunity to make representations, and then applied to the Natal Provincial Division for an order authorising the restriction of water supply to defaulting members. Nicholson J granted the order. The farmers appealed, contending inter alia that the association lacked the power to levy and recover such charges, particularly the dam-financing component, and that reliance on s 59 was unlawful where the existence or quantum of the debt was disputed.
