I cannot understand why the building of more storage reservoirs in the South East will solve drought problems when most of our supplies are from underground sources, unless transfer infrastructure is installed between the reservoirs and groundwater treatment works.
How we fill the reservoirs from depleted river sources I don't know. Infrastructure to transfer supplies between the different water suppliers should be installed and their use made mandatory in drought circumstances. With improved leakage rates and the use of grey water in all new buildings we should be able to look forward to, given time, a secure future for water in the South East.
