Townsville’s 2018 Wet Season and what comes after

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.

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”
