Re: How to lower water bill
I think it sounds like a lot of water in your wash routines. I use a prewash and normal wash, no extra washes, rinses, ect. If I had to do all that I would not be cloth diapering it would save us no money with german water prices.
Depending on how much you want to save you can limit toilet flusing, use collected shower water to flush the toilet. I use water from our consense dryer to flush the toilet when ever I use the dryer which normally is not too often. short showers, limit showers and baths. Things like that but not everyone like all that.
