Pipe Material
Remarks
Cast iron soil (building services
Use for building service connections
only)
carrying normal domestic sewage.
Cast ductile iron (gravity or
Primarily used for pressure sewers,
pressure)
yard piping within treatment plant
areas, submerged outfalls, exposed
locations, and portions of gravity
lines subjected to high velocities (10
fps [3.05 m/s]). Additional
applications include high external
loads, railroad crossings, major
highway crossings, and so forth.
Special linings, coatings, wrappings,
encasements, and so forth, are
required for corrosive wastes or soil
conditions. Gasket material should be
suitable for sewage or waste being
handled. Avoid cement lining for
sludge and domestic sewage receiving
less than secondary treatment.
Polyvinyl chloride (PVC)
Use for pressure force mains and
(pressure)
inverted siphons. Special care should
be given to trench loadings and
beddings.
Concrete (pressure)
Use for pressure force mains and
inverted siphons that are not
subjected to corrosive wastes or soil
conditions.
