In some regions water supplies are now barely adequate to support existing industry. It is thus evident that drastic measures for conserving water will be necessary to provide for industrial expansion where water is not abundant. Pure waste of water in industrial plants is much greater than management realizes. It is easy to find streams of water running to the sewer, apparently because it is too much trouble to shut a valve. It is common to see many times as much water being used than an operation actually requires.
