Manholes

Manholes are major elements of buried pipelines used for sanitary sewers and storm water management systems. They are commonly found where people access sewers for inspection and cleaning; and where there is a change in the direction or alignment of a pipeline or transition to a different size of pipe. Many have precast channels in the base, diverting effluent in new directions. Manholes are vents for gases emitted by the effluent in pipelines and junction points of two or more pipelines.

Because effluent turbulence is common in manholes, they are sometimes specified with liners or special additives to mitigate the corrosive actions of bacteria-generated gases that form corrosive sulfuric acid. TurnerCo. supplies manholes treated with the ConShield ani-corrosive system that is specified world-wide.
