A bypass is a system of pipes, pumps, hoses, and valves that help divert the flow from a pipe section that is under repair or rehabilitation. This temporary diversion allows the flow to continue when the primary line is blocked for rehabilitation. Bypass pumping is often used in sewer repairs to… View Full Term

A staging area is the area near a construction site that is used as a temporary area for the purpose of carrying out construction activities. It serves as a place for storing material, equipment, assembling pipelines and as a work area for the construction crew to begin construction…
A backdrop manhole is a drop shaft installed either externally or internally in a manhole in a sewer network. Backdrop manholes connect pipes of differing invert levels and allow for the pipe at a higher level to connect to the lower level pipe with minimum fall. Typically, backdrop…
Hoop stress is the stress that occurs along the pipe’s circumference when pressure is applied. Hoop stress acts perpendicular to the axial direction. Hoop stresses are tensile and generated to resist the bursting effect that results from the application of pressure. Three principal…
Microtunneling and horizontal directional drilling (HDD) are trenchless pipeline installation methods that are used extensively for laying pipelines. When two such tried and tested methods are combined, the result is usually a hybrid that incorporates the advantages of both methods. The…

It was in 1842 in Mohawk, New York that the oldest recorded modern concrete pipe was installed, and it lasted over 100 years. The concept of steel bars in concrete pipes was first introduced in France in 1896 and was known as the Monier patent. It was brought to the United States in 1905…
Trenchless tunneling methods have literally changed the shape of laying and maintaining underground piping and utilities over the last 50 years. From an innovative fringe idea, it has become a specialized sector of the construction environment. As the technology has progressed over the…
