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 86 ft3 or 640 gal (2400 L). 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. 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. This specification covers horizontally laid corrugated HDPE water quality units as illustrated in Fig. 1.
