Provide manholes at all breaks in the horizontal and vertical plane for 24-inch and smaller sewer
mains.
2) Provide manholes on 27-inch and larger sewers at all breaks in the horizontal and vertical planes,
except when the horizontal alignment is in a curve or when the use of bends has been approved,
see Part Two, Section 4 (Fittings) and Section 6 (Curved Horizontal Alignment).
3) When the design of the sewer is near an existing/proposed water pipeline 16-inch and larger,
which has a blowoff connection, locate the sewer manhole as close as possible to the blow-off
connection to allow for the discharge of chlorinated water
