Slide 28 of 52
Notes:
The preferred method for accomplishing a diversion is within the treatment practice itself (see left side of slide), where the overflow (or bypass) weir elevation is set equal to the design WQv elevation within the adjacent practice. This method ensures larger inflows will overflow the bypass weir, thus minimizing mixing within the treatment practice. It is also a more reliable capture technique, than reliance on a computed peak rate of discharge (Qp) to size the diversion structure.
