基恩供水系统。
有趣的是，来自新罕布什尔州基恩水务部门1915年报告中的一些细节显示，自1868年安装水厂以来，配电系统发生了迅速的变化，而且由于采用了改进的方法，这是必要的。负责这份报告的保罗·f·巴比奇(Paul F. Barbidge)说:“1868年7月3日，立法机构向基恩镇(Keene)颁发了一份宪章，并于8月13日投票决定将鹅池的水引入商业区。”这些计划是由来自马萨诸塞州伍斯特的菲尼亚斯·鲍尔(Phineas Ball, c.e.)制定的。工程是在他的指导下进行的。水管的第一个合同是由水和天然气管道公司专利的新泽西,谁comthe电源11月竣工,1869年,由8英里的总管和分支48龙头,耗资82000美元,是18000美元不到金额估计完成系统。第一个水库，塞尔万湖，比中心广场高155英尺，离中心广场约3英里。它占地51英亩，支流流域面积超过1500英亩。主坝由泥土筑成，中心的核心墙由石头和水泥筑成，厚度为18英寸，高度约为湖水应有的高度。1872年，在比奇山峡谷建造了一个容量为15,000,000加仑的辅助水库。这个水库在中央广场上方110英尺，大坝的建造和塞尔万湖的一样。1886年，由于伍德沃德湖(Woodward Pond)的额外供应，储水量增加了。罗克斯伯里现在被称为回声湖(Echo Lake)，距离基恩约7英里，占地140英亩，比城市高837英尺。 The intercepting dam on Roaring Brook is about three miles from the lake and 527 feet higher than the highest city point. In 1890 the first meters were installed, and in the following year all cement lined pipes were replaced with cast iron except a small quantity, which was afterwards renewed. In 1900 a pumping plant was installed at Richardson Ravine and 500,000 gallons per day pumped from the Ashuelot river into the system. An additional supply was constructed in 1902, when a dam 137 feet long, 19 feet high and 257 feet above the highest city point was built by the General Construction Company of New York City. In 1908 it was decided to rebuild Echo Lake dam menced work on September 3d. 1868. Laying at a cost of $6,000. The dam is earth with a concrete core wall and holds 530,000,000 gals. A 20-inch conduit takes the supply to distribution. The data was completed in 1910. the net earnings of the system in 1871 was $2,633.28, and in 1914, $29,691.54. The total length of mains is 47 miles, 1,312 feet, hydrants 314, gates 508, and pressure 50 to 75 pounds.
