Sanitary sewer rehabilitation can be disruptive to the neighborhood in the areas of the project work. The sewer system first has to be inspected through a variety of techniques that are part of a Sewer System Evaluation Survey (SSES). For example, the SSES might involve viewing the insides of the sewers using closed-circuit television (CCTV). To perform CCTV inspection, a robotic camera has to be lowered into a sewer manhole. The images are sent to a monitor located inside a large CCTV truck. Often, streets or lanes have to be closed to accommodate this activity.
Rehabilitation activities might require the removal of parts of old sewer lines or the installation of new sewers alongside the old lines. While there are “trenchless” technologies that minimize the amount of digging required, you can still expect openings in streets and along curbs, along with large digging and hauling equipment, and heavy truck traffic. The City is committed to minimizing the disruption as much as possible, and we will communicate with residents, businesses, commuters, and other stakeholders to provide advance notice of heavy impacts.
