STRATEGIC PLAN GUIDING PRINCIPLE Public Safety BACKGROUND The City systematically replaces sections of aging sewer infrastructure to ensure the continued reliability of the system. Each year, staff identifies pipelines that required excessive maintenance or experienced repeated service disruptions and target those pipelines for improvement. Closed circuit television inspection review of sanitary sewer basin DT2 in the downtown area and a portion of sanitary sewer basin 5G along Silver Hill Road were completed. Staff's review of the inspection videos revealed numerous defects in these sewer basins. A number of construction options for repair or replacement were evaluated to determine the most cost-effective method for mitigation. For this project, a traditional open trench was chosen in order to replace the identified pipe defects.
