DX4 is one of the more substantial drains that empties into a small tributary of the Humber River. We identified the drain by its major issue, An Inconvenient Tube. This pipe runs right through the middle of the drain and creates an obstacle to get past, either making one dirty or wet or both. Before reaching this delay the drain is made up of a variety of sizes of RCB from 3600mm all the way down to 1800mm. A short section of concrete bottomed CMP is after the inconvenience and this leads to the second problem, the 1800mm RCB. Really too small to continue in
