Sanitary & Storm Manholes

Sanitary & Storm Manholes

The precast concrete manhole is the standard used by today's civil engineers in the design of both sanitary and storm systems. The manholes are designed to expedite production and installation, while resulting in a safer work environment. The precast manholes allows for the excavation and installation to take place at the same time; therefore, an open hole is not required to be left open exposing the contractor to a change in weather conditions and other liabilities.
