Synthetic Runoff Testing of Stormwater Treatment Practices

Abstract

Synthetic runoff testing involves filling a stormwater treatment practice with water from a fire hydrant, water truck, or other available water source. Thus, synthetic runoff testing is limited to smaller practices. This chapter presents details related to using a water source to fill a practice, including determining if the water source is adequate and estimating the time it will take to fill the practice to a desired level. Analysis methods related to obtaining infiltration capacities and contaminant removal performance are given, as are examples, and a case study of synthetic runoff testing applied to an underground sedimentation practice.
