The waste and distribution system consists of one pipe stemming from the inlet weir tank to a tee and two pipes coming out of the exit weir tank that each connect to elbows in opposite directions. The inner pipe in the exit weir tank connects to an elbow that faces the inlet weir tank. There is a pipe that connects the elbow facing the inlet weir tank to the inlet tee. This part of the system accounts for the waste passage and outputs to the drainage channel on the inlet channel side of the sedimentation tank. The outer pipe in the exit weir tank leads to an elbow that connects to the distribution tank. The inlet pipe, inlet tee, exit pipes and elbows have all been elevated to the same elevation as the sedimentation tank drain valves so that all drainage occurs at the same height. An elbow must also be put in place that wraps around the inlet channel edge of the sedimentation tank and rotated 45 degrees to allow for minimum splashing of the waste water when it flows into the drainage channel.
The Drainage Channel
The drainage channel will run along the sedimentation tank on the side of the inlet channel. The channel will allow waste water from both inlet and exit channel tanks to run out to waste. It will be fed from an elbow connected to the inlet channel tank tee. The elbow will be rotated at 45 degrees from the base of the drain channel to minimize splashing and must allow for the exiting waste water to flow in the direction of the all drained waste water.
