Algorithm

Given the maximum flow rate through the treatment plant, and the number of sedimentation tanks in the plant, the flow rate for each sedimentation tank is determined. With a constant orifice spacing of 10 cm, and the given length of the sedimentation tank, the exact number of orifices in the pipe can be calculated:
With the drainage time set at 30 min, and the dimension values given by the water level at the sedimentation tank, the width and length of the sedimentation tank, the initial drain flow rate is estimated:
The diameter of the pipe is estimated through an iterative process, given the pipe database, the flow rate ratio, Q_ratio, and the following equation:

Later the head loss in the manifold is determined:

and with it, the diameter of the orifices:
