What Does Bypass Pumping Mean?

Bypass pumping is the pumping of sewage around a section of a sewer line in a pipe or channel specially constructed for that purpose.

The bypass allows the repair or replacement of a section of sewer without messy spillage on public or private property and without compromising the flow of water or sewage in the area while the repairs are underway.

Bypass pumping may be essential for projects requiring the breaching of sewer lines for spot mechanical repairs.


Trenchlesspedia Explains Bypass Pumping

There are two elements to bypass pumping: a waterway – either a trench or pipe. The normal flow is interrupted; it's diverted to a new path that circumvents a damaged area and returns to its normal path after the flow passes the damaged area.

The flow may be blocked while the bypass is installed or constructed; once the bypass is in place, a pump will be used to control the flow of water or sewage through the bypass.
