The Leak Repair Data Collection Guide is an open source MS Office Excel spreadsheet designed to aid the industry in collecting consistent failure data. This tool offers guidance to water utilities in the form of a standardized format to document failure events; thereby generating the appropriate data to execute a reliable leakage component analysis. Utilities that carefully document all failure events have a means to define failure trends occurring in their system.
