Excerpt from Conveyance and Distribution of Water for Water Supply: Aqueducts, Pipe-Lines and Distributing Systems, a Practical Treatise for Water-Works Engineers and Superintendents During the past fifty years, great progress has been made in the construction and operation of water works. Large aqueducts and reservoirs have been built, the efficiency of pumping engines has been improved, and the purification of water has been greatly advanced. A number of good treatises on water supply have been published during recent years, but as they all endeavor to cover the whole sub jcet, they necessarily fail to discuss some parts in sufficient detail to be of practical value to the waterworks engineer and superintendent.
