This also means the tanks are likely to be maintained, as the owners wanted them and have an investment in them. This 25 GL comes from only 8% of suitable houses having tanks installed per year over 3 years, let alone industry and other buildings. See the Marsden Jacobs report, and work by Assoc Prof Peter Coombs for detail. See the video by Chris Walsh on stormwater (EXPERT OPINION button at top of page). Also check out the testimony to the Parliamentary water inquiry on water options for Melbourne, and the SKM report on alternative options that the government tried to bury, and it was only released after successive FOI requests by Clean Oceans Foundation. Cheers, Neil. Hi Ian,

Couple of notes/comments: 1. 25 GL of supply from rainwater tanks would cost double that of desalinated water, and have 60% of the ongoing costs. Needs a lot more explanation as to why this is seen as a viable alternative, especially when one considers the significantly increased public health risk of numerous household water supplies prone to contamination, lack of maintenance etc. 2. Rationale behind stormwater capture is very airy fairy - storing in disconnected local reservoirs, old quarries, unspecified aquifers as well as new purpose built storages. Surely this posting is a summary of more detailed reports that should be provided, so the assumptions and conclusions could be reviewed and argued?
