It's Big. Period. The upstream portion of Humble Howard is being redirected to the MTI (Mid-Toronto Interceptor), which leaves the downstream portion virtually untouched unless a HUGE rainfall occurs. Three large overflow/storage tanks are located just downstream of where we entered. Roughly 20'x80' in size. On one side, overflow windows and a slide lead to the glorious brick drain itself. Side pipes downstream lead to other discoveries not yet fully explored, and a partially blocked end leads to a near dry pipe that connects to the infall at High Park South, and ends up slowly flooding as it flows under Lakeshore Rd, eventually being redirected (we believe) to the WBST.
