New Test Method for Determining the Trash Removal Performance of Stormwater Treatment devices

1. Scope

The promotion of knowledge of the family of technologies known internationally as stormwater control measures (SCMs), including stimulation of research and the development of test methods, specifications, practices, guides, and nomenclature. SCMs provide for stormwater quality treatment, volume control, flow management, and runoff detention, retention, and capture and use.

This activity shall support and serve as a resource for other ASTM committees in their activities that include stormwater control measure issues. This support may include dissemination of specific requests for standards throughout ASTM's existing committee base, as well as the maintenance of appropriate liaison relationships (internal and external) related to this subject area. The committee will not duplicate the efforts of existing ASTM technical committees. The work of this committee will be coordinated with other ASTM committees and other organizations having mutual interest.


gross solids removal; trash removal; stormwater treatment; laboratory test


Gross solids (trash) in stormwater has long been recognized as a problem and it has recently been regulated in the state of California, which has defined trash and introduced a TMDL. This has led to new claims for the trash removal capability of existing stormwater technologies as well as entirely new products for trash removal. There is currently no standard way to evaluate these claims. Manufacturers would use the standard to make credible claims, stormwater managers would reference the standard as a requirement to accepting new technologies.

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