Abstract:

Fort Carson, Colorado was the site of a comprehensive leak detection investigation of the potable water system with the express purpose of quantifying the benefits to be derived by a military installation from use of the technology. Military bases are often the size of a small city and the Directorate of Engineering and Housing has complete responsibility for all real estate (all buildings, all utilities, roads, grounds, etc.) unlike a municipal public works department. The investigation used state of the art noise correlation and computer correlation technology to survey the distribution system mains. Representative findings include: the majority of distribution system leaks were at hydrants or similar appurtenances; and family housing was found to be the other major concentration of leaks. However, where the first survey found 80 percent of housing units had leaks, preliminary findings from a second round in 1989 are on the order of 20 percent. The paper presents a complete lessons-learned section and also present cost figures and related information showing when and where leak detection surveys are appropriate.
