A small water district in Breckenridge, CO, was experiencing notably high water loss from November of 2015 through April of 2016. The apparent discrepancies in usage versus production led the utility to seek out the source(s) of the water loss. They contacted a consultant, Water Quality Control Professionals LLC (WQCP), to assist in the matter in order to lower their non-revenue water back to an acceptable level. To better gauge the source of the water loss and overall health of the distribution system, WQCP planned on conducting a leak detection survey as a means of locating water leakage within the system. However, depth and material of the water district’s main water lines made using traditional acoustic surveying methods more complex.
