Prior to final inspection, all pipelines shall be flushed and cleaned and all debris removed.
At the district’s discretion, gravity sewer lines shall be inspected for line and grade by checking each section between manholes for alignment. A full circle of light shall be seen by looking through the pipe at a light held in the manhole at the opposite end of the section of sewer line being inspected. Any corrections required in line and grade shall be made at the expense of the developer. Visual confirmation will require confined space entry compliance and will normally be considered where settlement is suspected. [Res. 735 § 1, 2017.]
