Wannon Water down Warrnambool way believes it has an Australian first. In a new housing development, it is taking water directly from rooves into the water system without it being diverted through drains, etc. How simple is that?
Of course, there is a question mark. Isn't there always? It decreases the amount of water going into the soil. Our soil - unconcreted, unpaved, unbuilt - is the best reservoir we have. We must always raise questions when water is diverted from it.
Now can we have that replicated and retrofitted everywhere so that we can postpone the need for desalination.
