Irrigating the sea of suburban lawns has been ramping up. Source Im a landscaper in the outer suburbs. We need better planning regulations, less turf, single famly homes and more rainwater havesting that isnt more large dams. Sydney's stormwater infrastructure is designed to get water into rivers and out too sea as quickly as possible. We should be storing more stormwater for irrigating green spaces and we shouldnt be using our drinking water. Its not a sustanable model even with climate change making droughts more intense.
