This database provides access to BMP performance data in a standardized format for over 190 BMP studies conducted over the past fifteen years. The database may be searched and/or downloaded on this Web site, and is also available on CD-ROM. Additional BMP studies are currently being prepared for the database. The database was developed by the Urban Water Resources Research Council (UWRRC) of ASCE under a cooperative agreement with the US Environmental Protection Agency.

Caltrans is the agency responsible for managing California's highway system. With its statewide Storm Water Management Program, Caltrans is helping to prevent the adverse effects of storm water runoff from Caltrans roadways and facilities. This Program provides a comprehensive effort to preserve and improve water quality in California.

The constructed wetlands-based treatment technology uses natural geochemical and biological processes inherent in an artificial wetland ecosystem to accumulate and remove metals, explosives, and other contaminants from influent waters. The process can use a filtration or degradation process.

The Governor's Office of Energy Management and Conservation (OEMC) designed a task force comprising key multidisciplinary wetlands experts to help demonstrate constructed wetlands to treat wastewater and to grow biomass for fuel production in Colorado. The first request for proposals (RFP) was awarded to HDR Engineering, Inc. HDR is teaming up with ERO environmental consultants to document and catalog the energy savings from existing Colorado constructed wetlands treating wastewater and the applicability of duplicating these designs in other Colorado locations. A second and subsequent RFP will utilize the findings from the first RFP to demonstrate a wetlands project to treat wastewater using the best features of existing Colorado constructed wetlands and to determine potential energy efficiency and conservation possibilities.
