In the event of a water system break or necessary maintenance work, the Wayne County Airport Authority (WCAA) maintenance division needed the ability to analyze the water system and perform a complete inventory of assets in order to be prepared to manage the system should either occurrence take place. Benesch worked with WCAA to tackle this challenge, performing a water audit and leak detection survey, a field verification of the water system and a hydraulic model of the water system. During the leak survey, field data was collected for the hydrants, valves, fire and domestic pumps, facility fire suppression systems and more. Handheld GPS units were used to collect a majority of these features as well as spatial locations and conditions of the assets. The field data collected was then used to update the WCAA’s existing GIS database. Additionally, this information was used to develop the model geometry. A field program was performed, and hydrant flows and pressures were collected. This information was used to calibrate and validate the model developed using EPANET. This comprehensive water system analysis was a complex task that prepared the WCAA for any emergency breaks or required maintenance that may occur to their system.
