Design Data 20: Circular Precast Concrete Manholes
Circular precast concrete manhole sections are versatile in the construction of buried structures; they may be used as catch basins for stormwater drainage, manholes providing access to buried pipelines, junction chambers at the intersection of sewers lines, and used to construct reservoirs or wetwells for pump stations. The use of precast concrete manhole structures will reduce construction time and labor costs, when compared to cast-in-place or masonry structures.
