MANHOLE SIZING RECOMMENDATIONS - Precast

The type of pipe entering the structure, and the connection method (boot, compression or mortar) must be known to accurately determine the required holes size and consequently, the manhole size. When possible, avoid pipes entering into structure joints and corners, as this may compromise the structural integrity and watertightness of the structure.
