Abstract: A manhole for connecting fluid flow between and for providing access to an inlet pipe and an outlet pipe angularly oriented to one another in a sewage, storm water or like fluid handling system. The manhole comprises an upright housing which defines a manhole interior, the housing having first and second essentially planar upstanding outer sidewalls angularly oriented to one another at substantially the same angle as between the inlet and outlet pipes and a curved upstanding outer side wall extending between the first and second planar sidewalls. First and second openings are formed respectively through the first and second planar sidewalls into the manhole interior for receiving respective ends of the inlet and outlet pipes. A base section within the manhole interior defines a curvilinear fluid flow trough between the first and second openings for conveying fluid flow from the inlet pipe to the outlet pipe.
