A Wonderful Water System.

A Wonderful Water System.

The city of Birmingham, England, is planning a new system of water supply, which involves an outlay of some $25,000,000, and nearly eighty miles of conduits, tunnels and pipes to bring the water to the city. The present consumption of the city, which is some days as high as 22,000,000 gallons, is rapidly exhausting the capacity of the watershed from which it is drawn, and the municipal authorities have selected as the site of the new reservoir a valley in Wales in which two rivers join. The valley is high, 800 feet above the city, is surrounded by a region practically uninhabitable, thus making the future pollution of the water improbable, and the supply is regarded as inexhaustible. The engineering difficulties are great, and include first the erection of dams which will make the first reservoir something over three miles long ; then comes nine miles of tunnel, principally through rock, thirty-five miles of conduit over and under the surface, and thirty-five miles of pipe. The plan contemplates five reservoirs in all, all connected and all independent, and scattered over an area of some seventy square miles. There is no such water system in England, and probably not in the world.
