WATERING - ALTERNATE-DAY ROSTER
I refer to the alternate-day watering roster that applies north of a line between Kalbarri and Kalgoorlie. What meteorological data was taken into consideration when it was determined that the roster would be the same for Marble Bar as it would be for Kununurra? Hon KIM CHANCE

AnswerView source ↗

I thank Hon Ken Baston for providing some notice of the question. The watering rosters for the two regions were determined by considering a number of factors, including the water saving potential, soil types and experience over several years. The meteorological data considered included rainfall, both frequency and intensity, and evaporation rates throughout the year. The zones were developed by John Colwill, garden consultant, and Chris Ferreira of the Great Gardens initiative. Garden experts agree that these measures will allow a Waterwise garden to remain healthy all year round. Information on Waterwise garden case studies in each region are available on the Water Corporation website.
