|We had TOO much water in Dec/Jan 2011|
|Three water tanks (about 22000 L) for our drinking water and the chickens|
|Out dam at Nanango is too saline for the garden, |
but ok for the cattle to drink.
For the house, we have three tanks about 20,000 L each, which are filled from run-off from the shed and the house. This is plenty for two people and they often overflow. If you need to estimate how many tanks you will need, consider how much water you will use (some estimates are 300 L/day, but I think you find that you use much less when you are paying for it directly, read more about our water conservation measures here), then work out the size of your catchment area and your average monthly rainfall. You can then estimate how much water you will harvest each month and how much you will use, and work out what buffer you will need in the form of tanks. Catching rainwater in tanks is by far the cheapest way to get more water, compared to digging a dam or a bore, so the more tanks you can afford to install, the better.
In 2014 we decided to replace two of the leaking metal water tanks pictured above with plastic tanks. See this post about moving the tanks around the yard. I wasn't convinced about getting plastic tanks (as we try not to drink out of plastic drink bottles), but the other options are not great either. Concrete tanks always end up leaking, as to the metal tanks, unless they have a plastic liner. After the tanks were installed I realised that the water was low pH and we had to add some limestone to neutralise the water (it was previously buffered by the rusting metal).
Overall, this means we’re responsible for both our drinking water and our waste water. If we stuff up, we have to pay, either buying water or having the septic pumped out, but I like to know that we are self-sufficient and can manage it all ourselves, without relying on the government or local council to tell us what we can and can't do.
Are you self-sufficient for water on your property?
