As part of a large scale sanitary sewer master planning study, Veritec, a Miya Group Company, was retained by the County to conduct a 12-site simultaneous sanitary sewer flow monitoring program. Veritec was responsible for the supply, installation, calibration, verification, data collection and analysis of the sites for a 6-weeks period in the spring of 2005.

A total of 7 sites were installed in the Port Dover sanitary sewer collection system and 5 sites were installed in the Port Rowan system Infiltration and Inflow analysis was conducted in specific sewer sub-sheds and compared against rainfall data information. Rainfall information was also collected by Veritec using data-logged tipping bucket rain gauges - one for each town. The information collected was used by G. Douglas Vallee Ltd. to complete a sanitary sewer system Master Plan and to assess system capacity for future developments.

The monitoring program revealed that the Port Dover system experiences a substantial amount of infiltration during the spring melt. The Port Rowan system experiences the same infiltrations issues but also suffers from inflow problems during rainfall events.
