Arto Precast Concrete Manhole Cover

Precast manholes consist of three components: namely the base, the riser and the cone. The base, as the name suggests, is the bottom part of a precast manhole and is also where the sewage/water pipe is connected. The cone section is the topmost part of a precast manhole and is where access to the manhole is provided. The risers in a precast manhole are mainly there to help achieve the necessary depth from ground level.
