SPECIAL
WASTES
803.1 Wastewater temperature.
Steam pipes shall not con
-
nect to any part of a drainage or plumbing system and
water above 150°F (66°C) shall not be discharged into any part of a drainage system. Such pipes shall discharge into
an indirect waste rece
ptor connected to the drainage system.
803.2 Neutralizing device required for corrosive wastes.
All discharges into the public sewers are subject to regu-
lation by the Department of Environmental Protection. The Department of Environmental Protection may pr
ohibit
the discharge of any corrosive
liquids,
including but not limited to
spent acids or other harmful chemicals that destroy
or injure a drain, sewer, soil or waste pipe, or create noxious or toxic fumes or interfere with sewage treatment
pro
-
cesses or
may require that such liquids be neutralized or treated prior to discharge in accordance with the Department
of Environmental Protection regulations. Where treatment prior to discharge is required by the Department of Envi-
ronmental Protection, liquids
shal
l
not be discharged into the plumbing system without being thoroughly
neutralized
or
treated in compliance with
the
rules
of
the Department of Environmental Protection
.

A chemical drainage and vent system shall be design
ed and installed in ac-
cordance with this code. Chemical drainage and vent systems shall be completely separated from the sanitary systems.
