CONCRETE PIPE Manhole Material Manhole material in the City of Winnipeg and surrounding jurisdictions are typically 1200 mm in diameter, with access to the manhole provided through a 750 mm diameter opening, with steps provided along the wall of the structure. In Regina and Saskatoon, the manhole opening provided is 635 mm. Prebenched manhole material, described on page 36, is made to order according to custom hole sizes and locations, whereas the standard material listed on this page (commonly referred to as “flat base and barrels”) allows for a “grab and go” alternative. Coring and benching of this material is performed by the contractor in the field.
