Drain that grew and grew
Features of Wilson Heights-Spadina Expressway storm trunk drain, Toronto, Ont; length of line selected is approximately 13,000 ft, and difference in elevation between invert of sewer at interchange and Don River outfall is approximately 136 ft; grade of sewer was chosen at 0.45% to keep maximum velocities below erosion velocity; with this grade, sewer was constructed from 34 to 80 ft below ground level until it interrupted gully which ran back in from river; feasibility of carrying water in open channel via gully with small spillways to dissipate energy was ascertained.
