We have heard that the water supply in the south east of England is coming under extreme stress following below average rainfall over the recent dry winters.
At present sewerage authorities remove the water used by domestic users and we are told that the quality of discharges from these sewage treatment works meet the very highest standards.
However, outfalls from inland sewage treatment works discharge into local rivers and are then recollected by water companies by abstraction from rivers.
Why don't the water companies take their water directly from sewage treatment outfalls?
