Sir: The amount of water wasted through leaky pipes may be difficult to ascertain (letter, 20 May) but another source of waste is easily proven.
Every day, Southern Water discharges the waste/sewage from 400,000 people into the sea off the West Sussex coast. Over 99 per cent of this effluent is water - fresh water.
If all the coastal water companies used inland sewage works, with the latest ultra-violet radiation that kills off most of the bugs, the resultant effluent would be so clean that, instead of taking water from the rivers and lakes as they do at the moment, it could be discharged there to be used again.
