Please see below a profile and plan view of an infiltration trench designed to treat and temporarily store stormwater for use in the City of Toronto located within the laneway between the road and sidewalk in a heavily urbanized location. This drawing depicts the use of an underdrain in the system where remaining stormwater runoff is directed to the nearby storm sewer system. | Please see below a profile and plan view of an infiltration trench designed to treat and temporarily store stormwater for use in the City of Toronto located within the laneway between the road and sidewalk in a heavily urbanized location.
