179   Circumstances in which private irrigation board not obliged to supply water
(1)  Nothing in this Part requires a private irrigation board to supply water to any land or landholder if, by reason of drought, accident or otherwise, the board is of the opinion that it is impracticable to do so.
(2)  Unless the private irrigation board otherwise determines, any failure to deliver water to a holding does not relieve the landholder of the holding of any liability for payment of rates and charges, and rates and charges continue to be leviable in respect of the holding despite any such failure.
