1.1 This practice provides recommendations for the installation of buried corrugated high-density polyethylene and polypropylene pipe in gravity flow agricultural applications. It is recommended for and limited to gravity flow subsurface drainage systems or water table control but not recommended for sanitary or storm sewer applications. 1.2 This practice applies to all agricultural subsurface drainage or water table control installations using Specifications F2306, F2648, F2736, F2764, or F2881. The scope of this practice necessarily excludes product performance criteria such as minimum pipe stiffness, maximum service deflection, or long-term strength. Thus, it is incumbent upon the product manufacturer, specifier, or project engineer to verify and assure that the pipe specified for an intended application, when installed according to procedures outlined in this practice, will provide a long-term, satisfactory performance according to criteria established for that application. A commentary on factors important in achieving a satisfactory installation is included in Appendix X1. NOTE 1-Specific paragraphs in the appendix are referenced in the body of this practice for informational purposes. 1.3 Units-The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Current procedures do not address new corrugated HDPE and PP standards for these applications. This will be used by Natural Resources, Bureau of Reclamation, Department of Agriculture, associated landowners, and installers.
