Many water system audits have been conducted in the absence of consistent definitions and standards and have often used inappropriate metrics for measuring the water supply efficiency. The Delaware River Basin Commission (DRBC) is one of a handful of regulatory agencies in the USA that has changed its regulations to reflect the improved approach to water loss accounting made possible by the IWA/AWWA methodology. The 2009 amendment to the DRBC Water Code requiring the new audit format was developed by DRBC staff and the DRBC’s Water Management Advisory Committee (WMAC). Compliance with the program was voluntary in 2011 and required in 2012. DRBC, in partnership with a number of large municipal and private water purveyors, has held workshops and training sessions for water system operators.
