Standard Specification for Corrugated High Density Polyethylene (HDPE) Water Quality Units
|Publication Date:||1 August 2017|
|ICS Code (Plastics pipes):||23.040.20|
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 86 ft3 or 640 gal (2,400 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.
FIG. 1 Horizontally Laid Corrugated HDPE Water Quality Units
HDPE water quality units contain three (3) chambers. A side inlet may be used in lieu of the end inlet and flow diverter when a full height longitudinal partition is constructed in the sediment chamber compartment to extend the particle travel length and isolate incoming flow from sediment build-up.
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, health and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
