剑桥（N. Y.）水劳动。
工程新闻描述了最近在纽约州剑桥市完成的新水工厂系统，如下所示：
系统是组合的泵送和重力。有两个水库；村庄以上175英尺，容量为400万加仑，仅用于防火；另一个位于村庄以下五十英尺处，是出于家庭用途。该水库的水必须被迫到达村庄，其目的是十二英尺高的胸部，车轮会产生足够的动力，每二十四小时泵送70,000加仑。当不消耗此数量时，余额将泵送到上层储层。下层水库由土地银行形成，其中包括一英亩的土地，弹簧的总流量从2000,000加仑到3,000,000加仑。上层水库由溪流和泉水喂食，距离村庄2 1/3英里，S-I-英寸供应主体从下层水库的6英寸部队主管距离水库约半英里处。，后者的主为半英里。在交界处放置一个自动阀，通常关闭，因此没有从上部储层抽水；在发生火灾的情况下，一旦打开消防栓并比泵所提供的水更多的水，压力降低会导致阀门打开，从而给上层储层带来了全压力； this operation requires from to 2 minutes. There are six miles of 8-inch, 6-inch and 4-inch cast-iron mains ; the service pipes are of galvanized iron ; there are 35 Ludlow double-nozzle hydrants and two drinking fountains, for which (with the exception of one hydrant) the city pays $1350 per annum ; the exception is a private hydrant, for which the company receives $40 per annum. The original contract was for thirty hydrants at $40 and the fountains at $25 per annum, and four more were added at $25 per annum.
