ASTM WK58870

    New Specification for Cellular Polypropylene (PP) Corrugated Wall Stormwater Collection Chambers

    (What is a Work Item?)

    Developed by Subcommittee: F17.65 | Committee F17 | Contact Staff Manager


    1. Scope

    1.1 This specification covers requirements, test methods, materials, and marking for cellular polypropylene (PP), open bottom, buried chambers of corrugated wall construction used for collection, detention, and retention of stormwater runoff. Applications include commercial, residential, agricultural, and highway drainage, including installation under parking lots and roadways. 1.2 Chambers are produced in arch shapes with dimensions based on chamber rise, chamber span, and wall stiffness. Chambers are manufactured with integral feet that provide base support. Chambers may include perforations to enhance water flow. Chambers must meet test requirements for arch stiffness, flattening, and accelerated weathering. Chamber end caps may be produced of PP or polyethylene (PE). 1.3 Analysis and experience have shown that the successful performance of this product depends upon the type and depth of bedding and backfill, and care in installation. This specification includes requirements for the manufacturer to provide chamber installation instructions to the purchaser. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address water quality issues or hydraulic performance requirements associated with its use. It is the responsibility of the user to ensure that appropriate engineering analysis is performed to evaluate the water quality issues and hydraulic performance requirements for each installation. 1.6 The following safety hazards caveat pertains only to the test method portion, Section 6, of this specification: 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.

    Standards currently exist for stormwater chambers, but they do not include additional requirements that should be required of cellular chambers. Although the standard is analogous to existing standards, this standard will address these additional specific requirements.

    The title and scope are in draft form and are under development within this ASTM Committee.
