1.1 This specification covers materials, structural design, physical dimensions and manufacturing requirements for monolithic or sectional corrugated high density polyethylene (HDPE) water quality units with volumes greater than or equal to 140 ft³ or 1,050 gal (4,000 L).

1.2 The corrugated HDPE water quality units are placed as offline or inline treatment devices along storm drain pipe lines to remove total suspended solids (TSS), heavy metals and phosphorous. Typical sources of pollutants include construction activity, automotive transportation related wear and debris items, refuse, landscaping debris, agricultural activities, and other similar by-products.

1.3 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.

1.4 This specification covers horizontally laid corrugated HDPE water quality units as illustrated in Fig. 1.

1.5 The following safety hazard caveat pertains only to the test methods portion, Section 9, 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.
