Additional meetings to assess the effectiveness of individual <br />elements are held as needed. Major studies, such as Sewer Master Plan audits and updates, and Infiltration <br />and Inflow Studies are also used to measure the effectiveness of the SSMP and make revisions as appropriate. <br /> <br />The City tracks the location and cause of all spills, blockages, and gravity main EMLs. The City maintains a <br />cleaning activity log, which details the size, material and location of each pipe cleaned, as well as the <br />equipment utilized, and any relevant remarks observed during the cleaning. The City utilizes field data <br />acquisition software (infraMap), which utilizes ESRI software for preventative maintenance tracking and work <br />orders. <br /> <br />City Field Staff observe all gravity mains and manholes during routine cleaning and conduct localized video <br />inspections when their observations warrant further investigation. Additionally, the City conducts system-wide <br />video inspections, and each pipe is given a score based on the National Association of Sewer Service <br /> pipeline rating system. All ratings are incorporated into the GIS so that all scoring is <br />associated with a corresponding pipe that has been inspected. These ratings, as well as the observed condition <br />of each pipeline, allow the City to identify gravity mains that are at risk of collapse or prone to more frequent <br />blockages due to pipe defects. <br /> <br />2025 ΘȃΑ <br /> <br />
