Acoustic Leak Survey of the Underground Potable Water System at a CONUS Army Installation

Abstract

U. S. Army Corps of Engineers Engineer Research and Development Center, Construction Engineering Research Laboratory (ERDC-CERL), and Carlyle Consulting’s John Carlyle conducted a leak detection survey at a U.S. Army Installation. The age of pipes in the distribution system ranged from 20 to 60 years. The thrust of the work was to acoustically survey all of the underground pipelines constituting the installation’s potable water distribution system and find any leaks. The results of the survey were that 6 leaks were discovered in the main lines, 63 leaks associated with fire hydrants, freeze proof hose bibs, water meters, etc., and 33 leaks inside buildings. Over two thousand acoustic measurements were made in order to obtain these results.

: Demonstration of Acoustic Sensing Techniques for Fuel-Distribution System Condition Monitoring : Final Report on Project F07-AR07

“…Previous research performed by the U.S. Engineer Research and Development Center, Construction Engineering Research Laboratory (ERDC-CERL) studied acoustic leak detection technologies on pipelines carrying potable water, high-temperature hot water, and other fluids (see for example: Morefield, Hock, and Carlyle 2006;Carlyle and Hock 2001;Carlyle, Van Blaricum, and Hock 2003). In the demonstration/validation project reported here, ERDC-CERL researchers implemented an Acoustic Fuel Distribution Monitoring System on the 4,300 foot long underground steel and aluminum pipelines of the Sabre Heliport Hot Refueling System (SHHRS) at Fort Campbell, KY.…”

Analysis on Heat-Insulating Property of the New-Type Water Transporting Vehicle Based on ANSYS

“…With review of the water transporting equipments in domestic and foreign cold area [1][2][3][4][5][6], either heat-insulating structure or heating unit is adopted, however, the heat-insulation effects are different. By reference to domestic and foreign advanced technologies, a new-type self-propelled water transporting vehicle designed with active heating and passive heat-insulating technologies after analysis and improvements for many times [7].…”

Ferrying Performance Analysis of a New Type All-Terrain Tracked Water Carrier

“…There are many reports about all-terrain vehicles, but report about customized tracked vehicle focusing only on water transportation is rarely to see. Most of water carriers are modified on universal all-terrain vehicle [1][2][3][4][5], such as BV206 produced by Swedish HAGGLUNDS, 2.47t armored logistic transportation vehicle produced by Canadian LAV, multipurpose armored transportation trailer produced by Russian MT-LB. Taking those as reference and benefiting from the advance technology from oversea and domestic, this new type all-terrain tracked water carrier is designed.…”
