Performed a CCTV inspection of the sewer line, extending about 120 feet from the external cleanout to the manhole located near the driveway. This involved using advanced camera technology to assess the pipe’s condition thoroughly. Based on the findings, I recommend installing a liner from the cleanout to the manhole to ensure integrity and prevent future issues. A detailed proposal for this liner installation in Evanston will be provided, outlining the technical specifications and costs.
