How we save nearly 2000 litres of water a year


It’s this simple!

We all know that water is a valuable resource and one that shouldn’t be thrown away lightly.

Some of us are still in mains water, so here’s a way to save quite a bit of that precious and increasingly expensive resource. The idea works for those on tank and bore water too.

Here’s how we save a almost 2000 litres a year…

The idea is simple. A 1 litre bottle of water placed in the cistern of a toilet will displace 1 litre of cistern water. That keeps the float valve always just a little bit higher, causing less water to flow into the cistern. I’m assuming you already have the float valve adjusted to the minimum.

The pic above shows how easy it is. Just fill a bottle with water. pop the cistern lid, slide in the bottle where it won’t catch on anything like the float and pop the lid back on.

The next time you flush, you will be using a litre less water.

So…how much will it save (the number of flushes is just an estimate on use)?

Lets say you have 5 flushes a day. Thats 5 litres a day saved 365 times over a year.

5 x 365 = 1825 litres (or 482 US liquid gallons)

To show you how much that is, the average IBC (those big square white containers that folks reuse for rainwater) in Australia is 1000 litres. Thats almost 2 IBCs that youre saving.

1000 litres is 1 cubic metre, so you’re saving nearly 2 cubic metres of water a year.

1 cubic metre weighs 1 tonne…

You get the idea!

All for the cost of a free bottle!

  1. A few years ago, our water board was giving out inflatable bricks to put in the cistern to save water. I’m wondering if I now added a bottle as well the flush would still be sufficient. Might give it a go!
