My darling man came home from his weekend away to the bucket in the loo, ready to collect all our liquid gold. In discussing the whole issue, we did some rough calculations and realised that we'd save in excess of 20,000 litres of water each year by collecting rather than flushing.
Here are the numbers (based on old loo - we estimated 6 litres per flush):
Weekend days: 12 less flushes = 72 litres saved
Week days: 8 less flushes = 48 litres saved
Weekly total = 384 litres saved
Yearly total = 19,968 litres saved
These are only our flushes and are not counting the children's contributions when they are here. That means for our family alone, we will save more than 20,000 litres of water per year and probably more like 25,000 litres. I wish we'd done these calculations a while ago. It is quite staggering.
love and light
