jno, ^^
That is exactly what I meant, The answer is to build dams and reservoirs up in the hills so the water is collected and stored and released when needed. For example in summer to avoid a hosepipe ban. In addition to the obvious problems,( loss of land ,wildlife habitats and the rest) there is the massive cost and who is going to pay for it. The government sold off the water boards to make a quick profit and none of the private ( and nearly 100% foreign owned) water companies are going to pay the £billions cost.
