Our taps are fed directly from the Murray river with no storage inbetween. Up until 8 or 9 years ago, it wasn't even filtered - and the brown sludge that used to come out of the taps would make you sick just to look at it! Talk of being fed from the "rear end" of the Murray had real meaning in those days.:oo:
One of the first things we did when we built about 12 years ago, was to put in a 2500 litre rainwater tank that is plumbed to gravity feed a tap on the kitchen sink - and we just DON'T drink anything else.
While water is still a big issue, one of my personal philiosophies is "Never let what you CAN'T do get in the way of what you CAN." So, while I can't solve Australia's water crisis, I've done as much as I can in my own little corner. In addition to the drinking tank, I have a 22500 litre tank fed from my 20'x30' shed, and a 1000 litre tank picking up most of the house rain water that doesn't make it to the drinking tank. A submersible pump in the 1000 litre tank shifts the water up to the 22500 litre tank.
In the summer, I pump water from the big tank to feed drippers on all my fruit trees, vegetable garden, and other sundry productive plantings. When the tank is empty, irrigations stops. I don't use any mains water in the garden at all. The front yard, has only plants that are supposed to survive on what falls from the sky, and so receive no artifical assistance. Our front lawn (and I use the term advisedly), fluctuates from green and lush to brown and crispy on a seasonal rotation.
In the winter, once the main tank has refilled, I throw a couple of valves and shut off the mains all together, running the entire house on rainwater from the tank. The record stands at having the mains switched off for seven months. Three to five would be more of an average figure, but is almost totally dependant on rainfall in the year in question. There is also a bit of guesswork involved - knowing when to switch the mains back on allowing enough future rainfall to refill the tank so there is something left for the fruit trees next summer.
All the talk from our premier about boosting restrictions means nothing to me - since cutting back lawn watering from three days a week to one day a week is fairly meaningless when you havn't watered the lawn in years anyway! Sure, I'm not going to win any neighbourhood gardening competitions, but at least I know I've done my bit.
