The point made by my former colleague David Eddy (NCE last week) about efuent reuse is valid but I doubt that many water companies take it into account in their planning especially in the water-poor south of England.
One of the principal problems is that most of the water companies there are just that - suppliers of water only.
In our case, water is supplied by South East Water but sewage is treated by Southern Water and discharged to sea when it could be pumped inland for further treatment and used to augment river ows.
Surely a case for rationalising water and wastewater management by eliminating the companies that only supply water?
