Frequently Asked Questions (FAQ)

Question:
What is a BMP "treatment train"?

ANSWER:
Because BMPs usually cannot treat every pollutant all of the time, some designers utilize a system called a BMP 'treatment train.' These systems consist of various BMPs laid out in series so that one BMP's effluent is the next BMP's influent'one BMP would treat one pollutant while the next BMP would treat another. For example, disinfection and infiltration BMPs work best when there are minimum amounts of trash and solids in the stormwater. Therefore, installing some kind of trash and solids separation BMP upstream of a disinfection or infiltration BMP would be a beneficial design.
