A grease interceptor shall be installed in the
waste line leading from sinks, drains or other fixtures in the following
establishments when, in the judgment of the Plumbing Inspector, a
hazard exists: restaurants, hotel kitchens, bars, factory, school,
social or other cafeterias or restaurants, clubs or other establishments
where grease can be introduced into the drainage system in quantities
that can effect line stoppage or hinder sewage disposal.
Every public garage, service station or other
structure for the housing, sale, servicing or repair of motor vehicles
shall be provided with a proper means for draining the floors or pits.
They shall have a special connection discharging through an intercepting
trap, located under the direction of the Plumbing Inspector. Such
trap shall be so arranged as to intercept all oil, gasoline or other
inflammable fluids, sand, silt and all other solids for the purpose
of excluding the same from the sewage system. Such trap shall be watertight,
so located as to be easily accessible for cleaning and inspection
provided with a suitable manhole frame and cover and of a design and
capacity approved by the Plumbing Inspector in advance of installation.
Oil, gasoline or other inflammable fluids, sand, silt or other solids
shall be regularly removed and promptly disposed of, and the trap
shall be so maintained to ensure the exclusion of such substances
from the sewerage system.
Garbage grinders or disposal units may be installed
in private residences only and shall be subject to the approval of
the Plumbing Inspector as to the ability of such grinder to properly
grind food waste disposed of therein.
No direct cross-connections shall be made between
the water supply and plumbing connected to the sewer in such manner
as to permit back-siphonage of sewage in the water supply system.
A sump pump may be connected to the building
drain only under the following conditions:
A. Only domestic sewage waste originating within the
household shall be discharged from the sump.
B. The sump shall be constructed with watertight sides
and bottom and shall admit no ground- or surface waters. No pipe shall
discharge into the sump which serves to drain groundwater under cellar
floor slabs or from around foundations.
C. Where any sump pump is connected to the sewer, it
shall be noted upon the plumbing permit, and the Town shall at all
times have the right to inspect the sump, and in the event that water
other than domestic sewage waste are determined to be entering the
sump, the Town shall have the right to order the disconnection of
said sump from the sewer and such order shall be immediately carried
out.
It shall be the duty of every person to whom
a plumbing permit shall hereafter be issued to promptly notify the
Plumbing Inspector of any additional fixtures which may be installed
within the property to which the plumbing permit refers.
