(Practice)Standard Practice for Installation of Thermoplastic Pipe and Corrugated Pipe in Septic Tank Leach Fields
Standard Practice for Installation of Thermoplastic Pipe and Corrugated Pipe in Septic Tank Leach Fields
SCOPE
1.1 This practice describes procedures for handling and installing thermoplastic pipe and corrugated pipe in septic tank leach fields, curtain drains, and from the septic tank to the leach field. Proper installation ensures that the pipe will satisfactorily convey and distribute partially treated waste water to a leaching field for additional treatment and disposal by soil absorption. The curtain or perimeter drain will function to protect the soil absorption capacity of the leach field.
1.2 To ensure compliance with local regulatory provisions, the local approving authority (local health departments and so forth) should be contacted regarding specific requirements for leach field design materials and installation.
1.3 This practice applies to pipe and fittings made under each of the following ASTM specifications:
1.3.1 For transport from tank to leach field: Specifications D 2680, D 2729, D 2751, D 2852, D 3034, F 405, F 758, F 789, F 810, F 891, F 892, and F 949.
1.3.2 Perforated, for use in leach field or curtain drain: Specifications D 2729, D 2751, F 405, F 810, F 891, and F 892.
1.4 Pipe intended for installation in accordance with this practice should have a minimum pipe stiffness as specified in the appropriate product standard referenced in 1.3.1 or 1.3.2.
1.5 The values stated in inch-pound units are to be regarded as the standard.
1.6 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. For specific precautionary statements, see Section 7.
