Inverted Siphon (Depressed Sewer) Design Calculation

Special care must be taken in inverted siphon design since losses are greater for pressurized flow, and the velocity in each siphon pipe must be at least 3 ft/s (0.9 m/s) for sewage or 4 ft/s (1.2 m/s) for storm water (Metcalf and Eddy, 1981). Therefore, even if there is only one main sewer pipe, several siphons may be required.

Typically, cement integrity is ascertained by the drill bit when the operator attempts to kick off from the plug. Any failure of the cement requires the operator to start over: drill out the cement, trip out of the hole, acquire and mix a new batch of cement, set a new plug, allow it to cure and attempt another kickoff—all at sub-
