  3. Pipeline Standard (516) • Working pressure shall not exceed 72% of the pressure rating of the pipe • Approved backflow device shall be installed if the pipeline may be used for human consumption • Will be buried below frost line or protected from freezing

  4. Pipeline Installation • Must be installed to the minimum depth specified on the plans • Typically 24” to 36” depending on area of the state • System shall be pressure tested at the designed working pressure for 2 hours

  5. Pipeline Installation • If limestone or large rock is encountered, the pipe may need bedding: • Trench shall be undercut a minimum of 4 inches • 4 inches of sand, compacted fine grain soils, crushed limestone (#11) or pea gravel • Final backfill material shall be free of large rocks, frozen clods, and other debris greater than 3 inches in diameter
