Just had our water meter bill through our door today. bearing in mind that we live in a 3 bed house, have a 2 adults and a 2 1/2year old living here, dog,cat & rabbit, 10ft x 10ft greenhouse to water, 20ft x 10ft veg garden, and i use a 200gpd R.O System that uses 3000lts of water to make 1000lts pure water at the minute. and this is what our bill was:- period of charges 17th November 2011 - 18th May 2012 Total water charge:- £89.31 Total Sewerage Charge :- £113.96 Total of £203.27 for 6 months. that only works out to be £33.88 a month. £8.47 a week! so goes to show even on a water meter it dont cost as much as you think to have a meter fitted!
