HDPE Buried Design - Plastics Pipe Institute
For the purpose of calculation, buried installations of PE pipe can be separated into four categories depending on the depth of cover, surface loading, ground water level, and pipe diameter, as follows Standard Installation-Trench or Embankment. Maximum cover of 50 ft, with or without traffic, rail, or surcharge loading; minimum cover of at least one diameter or 18-in., whichever is greater.

Loads on Buried Pipes - CivilWeb Spreadsheets
Imposed Loads on Buried Pipes – Uniformly Distributed Surcharges of Large Extents. Large uniformly distributed surcharge loads on buried pipes can be modelled by increasing the effective depth of the cover above the pipe. The additional cover depth will depend on the magnitude of the surcharge load and the unit weight of the soil.

Safe burial depths vary and should be calculated. In lieu of calculations AWWA says that for an embedment soil with an E’ of 1000 psi and no surface water, HDPE pipes with DR’s ranging from 7.3 to 21 can be safely buried from a depth of 2 ft to 25 ft where no traffic load is present and from 3 ft to 25 ft where H 2 0 live load is present. Most pipes can be buried to deeper depths.
