We’re officially in Winter now and I reckon we moved definitively into the Dry season a fortnight ago, so it’s worth looking back at the Wet and seeing what’s likely to happen to our water supply in the Dry.
Wet season rainfall and the year to come
BoM climate data reveals that our rainfall so far this year, Jan – Feb – Mar – April – May, was 118 – 285 – 343 – 10 – 2 mm, for a total of 760 mm.

The dry season is so long and so dry that no tank will last through it.” One group must be wrong, and the only way to find out is to crunch a few numbers.

Level 3 (sprinklers not to be used, handheld watering 6-7am and 6-7pm only, odds and evens applies to handheld watering) is tough enough on gardens – and gardeners – and Level 4 (no sprinklers or handheld watering allowed, watering cans/buckets only, odds and evens applies to watering cans/buckets) will be far worse. In these conditions, using grey water is one of the most significant options Continue reading “Grey water – keeping gardens alive during water restrictions”
