Construction of a Sewage Pumping Station, Part 3: Pipe Connections to the Sewer System

Now that the wet well is installed, it must be connected to the existing sewage system. This requires drilling entry and exit ports for the plumbing and installing the large pipes to make the connections. Since sewage flow is largely accomplished by gravity, the pipes must maintain the correct slope along their path, so the ports in the wet well are drilled on-site to achieve the proper alignment.

How do you “cut over” from the existing pipes to the new system without taking it down? That’s where manholes get into the act.


Is this still a word? My gosh, think of the impermissible permutations!


Thank you.
