Rainwater harvesting is designed to save water
What isnt mentioned is that the energy use of a rainwater harvesting system is still relatively small, and that these systems are not a method of reducing C02, but are designed to save water, supplies of which are under severe strain. Whilst carbon emissions are a key problem to solve, it would pale into insignificance very quickly if we had no water to drink, wash and flush toilets which as we know can bring communities to a standstill within a matter of days.

Localised calculations vs Infrastructure costs
What the article / study doesnt discuss is the carbon footprint of centralised infrastructure vs decentralised (ie at the home).
As an example, the use of a greywater irrigation system including a pump, uses one tenth of the energy required to capture, treat and redistribute greywater from a municipal treatment plant.
