THE GRAVITY SYSTEM OF ASTORIA, ORE. Specially written for FIRE AND WATER ENGINEERING. The difficulty experienced by engineers in locating sources of water-supplies in many of the cities and towns of the States on the Pacific coast, have presented themselves in many instances, owing principally to the expense of laying long lines of conduits to acquire sufficient pressure for fire purposes. California, Washington and Oregon have passed through the experience of providing such supplies with a fair measure of success, and those States now probably contain the best examples of gravity systems of any other part of the country. Colorado depends upon its snowdad hills to fill natural collecting reservoirs along the mountain sides. While this may prove satisfactory at certain times, the uncertainty of keeping up the supply from this artificial source is apparent, especially with such cities as Denver and Colorado Springs, whose populations are increasing at a…
