Letters to the Editor Roll Out the Tanks
There was 1085mm rainfall in Sydney in the 12 months to September 13, 2006. An average house using five 1KL rainwater tanks (one for each downpipe giving 5KL storage capacity) would have yielded 100KL of water - enough to supply two-thirds of household water used indoors each year.
Rainwater will cost under $1.50/KL if tanks are installed in all houses and buildings. Mains water costs $1.20/KL but it won't be long before mains water costs more than rainwater. Recycled stormwater is unlikely to be cheaper because of the cost to collect, treat and pipe it back to the buildings it came from. Large-scale manufacture and installation of rainwater tanks will guarantee a cost of $3,000 per house. Reduction in mains drinking water consumption can become mandatory at point of sale of a building (enabling simplest, lowest cost financing) with rainwater tanks complying. Most houses can have rainwater supply within seven years because this is the average turnover of houses. Rainwater tanks are Sydney� cheapest and most sustainable source of additional water supply.
