18-29-306.3 Backfilling.

Backfill shall be free from discarded construction material and debris. Loose earth, free from rocks, broken concrete, frozen chunks and other rubble, shall be placed in the trench in 6-inch (150 mm) layers and tamped in place until the crown of the pipe is covered by 12 inches (305 mm) of tamped earth. The backfill under and beside the pipe shall be compacted for pipe support. Backfill shall be brought up evenly on both sides of the pipe so that the pipe remains aligned. In instances where the manufacturer's installation instructions are more restrictive than those prescribed by this chapter, the material shall be installed in accordance with the more restrictive requirement. (Amend Coun. J. 10-14-21, p. 37722, Art. III, § 10)
