Using Rainwater wisely

Its a good idea, but i do wonder whether the supermarkets would really want to pay for the change.

The other thing thoug, i doubt urinals use more water than flushing the womens toilets. Its like comparing a few short showers to filling a bath.

 

I believe they fit a devise to mens urinals these days similar to a motion sensor on lighting, so that the urinals only flush when there is movement.

 

I think although the rain water may appear to be wasted when it runs off a roof, its not unless its directed into the sewers.
If it goes into a soakaway it eventuall reaches the water table and becomes part of the ground waters that many of the water companies extract.
I remember a few years ago the water people were saying that due to lack of rain the sewers weren't being flushed through properly, so maybe even rainwater directed into the sewers provides a service.
There are too many of us and not enough water, until they realise that, we will have problems.

 

Another point the water would have to be treated in some way storing water and passing it through pipes would lead to a problem of algae build up, you would have all sorts of gligamaglogs growing in the system. :eek:
