Development of Certification Guidelines for Manufactured Stormwater BMPs

Manufactured stormwater Best Management Practices (BMPs) are becoming an integral part of stormwater infrastructure, as well as a component of wet-weather flow technology. They are commonly used but there are few guidelines regarding the use of these manufactured devices. An ASCE/EWRI task committee was formed in May 2007 to develop guidelines for the certification of manufactured stormwater BMPs. The committee kickoff meeting was held at the EWRI 2007 Congress in Tampa, Florida. At this meeting, the scope of work was discussed, with the consensus being to focus on physical separation of particles for the full spectrum of stormwater-borne non-dissolved solids. Complex issues regarding testing and certification BMPs were identified, and six subcommittees were formed to address these issues simultaneously. These six subcommittees are: (1) Laboratory Testing, (2) Field Monitoring, (3) Scaling, (4) Data Evaluation, (5) Data Reporting, and (6) Maintenance. This paper provides the results of the Task Committee work to date (January 2008), including review of the existing test, verification, and certification procedures and protocols and identification of additional standards development.
