Wet Weather Flow Master Plan (WWFMP)
Toronto City Council adopted the Wet Weather Flow Master Plan (WWFMP) and a 25-Year Implementation Plan in 2003. The goal of the WWFMP is to reduce and ultimately eliminate the adverse impacts of wet weather flow, which is runoff generated when it rains or snows, to protect our environment improve the ecosystem health of the watersheds. The Plan was developed with the recognition that wet weather flow will be managed on a watershed basis accompanied by a hierarchy of solutions starting with “at source”, followed by “conveyance,” and concluding with “end-of-pipe.” What's it all about?
