CORRESPONDENCE
总监Diven和Troy供水。
给编辑： - 如果计划，如纽约州特洛伊的水工厂校长约翰·M·迪恩（John M.在没有蒸锅的帮助下，可能会从小火上放出。现在，一些改进将是有道理的，如果不是为了延迟该部门从Tomhannock安装新管道的延误，Tomhannock将在兰辛堡（Lansingburgh）降落第六和第七大道。这项工作的合同是在一段时间前给出的，但可能至少要添加最后一个月。一旦安装管道，部门计划就开始实验，以增加服务低点的压力。副校长Diven指出，随着新的和新的管道在低服务中工作，这座城市的压力将在油磨山的脚下的压力为140磅，这将使在整个低服务中施加更高的压力，这将有可能。由于许多房屋中的管道不会承受压力，因此不能给予压力的全部好处，并且为防止置于管道而增加的压力的麻烦只有程度才能逐步增加，直到学习什么压力可以毫无麻烦地站在房屋中。一旦新管道完成，额外压力的计划就会开始。给予人施加额外的10磅压力，几周后，如果发现一切完美，将增加五磅，将逐渐增加的金额增加，直到达到房屋管道所达到的全部压力为止。 It was stated that the Tomhannock supply could give all the water needed in the low service and the intention is to eventually use only the low and high service, abandoning the middle service altogether except as an auxiliary in case of trouble. The middle service, for the most part, according to the plans, would be by means of valves, already in position, turned into the low service and part into the high service lines. The present pipe line of the middle service would be allowed to remain so that it could be used if it was found necessary, but the superintendent thinks it will not. With a pressure of more than seventy-five pounds in the mains south of Lansingburgh, the North End section would receive a pressure of more than a hundred pounds, making it practically unnecessary to use fire engines in that territorv and only on rare occasions in the old city. The intention of the department is to give the mains a thorough flushing and after this has been done, with the regulating of the pressure, it is not likely that the Oakwood and Lansingburgh reservoirs will be abandoned, as Superintendent Diven states that he does not think the water in cither reservoir is as good as that in the Tomhannock. After action on the pressure, cleansing of mains and the abandonment of the reservoirs, the next step of the department will probably be the filtering of the water used by Trojans. The city recently has purchased property in the vicinity of the northern turnpike, at the end of Oil Mill hill, and this would be an ideal location for the filtering plant. Superintendent Diven states that in a year or two the city will have to erect a plant to filter the citv’s supplv of water, and if it does not build the plant of its own accord it will probably be compelled to do so by the State. A filtering plant, declared the superintendent, will mean eventually the wiping out of the spring water business.
