What is different about water tanks & stormwater in Townsville
Townsville has one of the highest household water uses in Australia and periodic restrictions tied to Ross River Dam, which makes rainwater tanks a practical hedge. The catch is the rainfall pattern: the dry tropics get most of their rain in a short wet season, so a tank fills between December and April and has to be managed through a long dry. Tanks here are best sized to carry garden and outdoor use into the dry, and plumbed to toilets and laundry for a steady saving through the wet.
