the water companys around the south of england are slowly putting water meters, and finding leaks that have been happening for years
thats the bad bit!
but the good bit, is that im Very busy replaceing them through peoples insurances
but it is all bull... if china can convert sea water in to drinking water,,,, why cant we?
i know some new "eco" houses use "grey" water which is bath water / shower water filterd in to a tank and is then used to flush the toilets!
also, if you make your toilet flush with less than 6L of water , you can potentually get alot more blockages = more expence!
