And a 1000 litre tank is only going to be used for the garden, hardly worth hooking up to the house.
Stupidity kills. Absolute stupidity kills absolutely.

Hey Woodbe,
I bet you have a nice garden with flowers and lawn that you irrigate, How many people does that feed and clothe?
Do you recycle your tail water?
Do you know your own water use efficiency rate?
Agricultural production in NSW continues to exceed the rate of population growth depite irrigation entitlements continually being reduced by governments.
the federal government's 2001 State of the Environment report calculated that the Sydney Water Corporation released 548 GL of wastewater, and 420 GL of stormwater to the sea in one year.
Do you wear cotton underpants?
Are you hungry yet?Cheers,

I wonder if in preparing statistics of agricultural water use that the evaporation and leakage from open channels (which is around 90%) has been included as "agricultural" use.
This distorts the true agricultural water usage statistics.
It is water lost due to obsolete delivery systems.
This is the responsibility of governments who continue to shirk their role.
I contend if open channels were piped or covered there wouldn't be a water shortage.

Actually, in SA at least, the tank rebate involves plumbing into the house and some sort of switchover mechanism. It is directly targetted at Mr Joe and Jane Public. No plumbing = no rebate. The desired impact definitely seems to be to replace some domestic consumption with tank water.

Value of production divided by quantity of water used.
There's nothing personal about it. It just gets right up my nose that so many people read or hear figures like you have and what the water produces and provides is forgotten.
A farmer is a business man and if he's not he's not going to be a farmer for long, Ask yourself this question
Would any business man spend more money or use more resources producing his product than he has to, to satisfy the market?Cheers,

That's the point, isn't it. There is a trade off between money and resources. It costs a lot of money to make significant inroads in water use. So in your example, the business man may save money by using a cheap resource inefficiently.
An urban example. The car wash. It costs between $5 and $25 depending where you go, and the wash itself uses maybe 200 litres of water (guess, I have no idea really, but I can't imagine it's more than that) Water in SA costs just $1.09 per 1000 litres, so when the water per car wash costs just $0.20 where is the motivation to save it? Thankfully, the government has stepped in and forced water efficiency on the industry, but the major costs of the business would have to be wages, power and rent for land and machinery.
It's a competitive market, and the unit cost of production is a big single deciding factor for profit. Water doesn't cost enough to hit the business cost radar unless the business is using an awful lot of it.
Value of production divided by quantity of water used.
Note that this efficiency measure is dependant on market. I'd guess that the high water usage crops score well on it, but given that most of that stuff is exported, that's a bit like filling tankers with Aussie water and sending it overseas. Nice when we have excess water, but in times of shortage...

so what is the answer do we keep saving water until there is none left to save or do we make it rain more

Swimming Pools
OK, I'm going to stick my neck out a country kilometer.
When I purchased my house, it had a swimming pool which holds about 20,000 litres of water. If I spent about $45,000, I could have it removed and the space re-landscaped, and perhaps that's what I will end up doing.
However, in the meantime, I and tens of thousands of pool owners are faced with a dilemma. Stage 4 water restrictions will only allow pool topping-up by bucket. The bucket must be filled at a tap, not by a hose.
Although I recently purchased a pool cover to minimise evaporation, the pool still looses about 10mm of water per week. Once the water level drops below the skimmer box, the filtration system will no longer function. I haven't started to top the pool with buckets yet, but it wouldn't surprise me if this took hundreds of bucket per week (if not more). If I can keep up, I may be able to keep the pool filtered and avoid stagnation, algae growth and mosquito infestation. But I can imagine that there will be many pool owners that won't or can't keep there pools maintained.
What are the potential health hazards of this?
