Water

So there it is - our 'Gem'. It's not really in service anymore this water tank, we feed on the ones next to our house (on the bottom in the picture). We haven't got mains water so are living of rainwater that we catch via the roofs and which is stored in 3 massive tanks (total of 30 thousand liters). Ideal for Annet to do a study with our recently purchased digital rain gauge. How much are we using and how much do we catch? Considering the drought over here, we need to get an idea.

OK we are using about 250 to 300 liter per day so with full tanks well be fine for 100 days (although the tanks aren't suppose to get empty all the way of course). It has rained just 28 mm in the past 5 weeks (that's nothing really). This gives us, with our roof surface, about 6000 liters in the tank. That's about 45 cm per tank and we should be good for 20 days, for showers and cooking.

And of course after all that maths it has to be checked as well. The high tech method over here (that everbody uses) is to knock on the tank and listen to the difference of sound, indicating the water level. And, yes, it matches perfectly - bunch of freaks we're turning into. And very well aware of our water consumption.

At night we hear the possums having a ball on our roof. Where would they go for a piss? Surely not on our roof...
