Where installed, all grease, oil and sand interceptors
shall be maintained by the owner at his expense in continuously efficient
operation at all times.
Where preliminary treatment facilities are provided
for any waters or wastes, they shall be maintained continuously in
satisfactory and effective operation by the owner at his expense.
When required by the Superintendent, the owner
of any property served by a building sewer carrying industrial wastes
shall install a suitable control manhole in the building sewer to
facilitate observation, sampling and measurements of the wastes. Such
manhole, when required, shall be accessibly and safely located and
shall be constructed in accordance with plans approved by the Superintendent.
The manhole shall be installed by the owner at his expense and shall
be maintained by him so as to be safe and accessible at all times.
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in §§
102-29 and
102-32 shall be determined in accordance with Standard Methods for the Examination of Water and Sewage and shall be determined at the control manhole provided for in §
102-34 or upon suitable samples taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected.
No statement contained in this article shall
be construed as preventing any special agreement or arrangement between
the Town or other public authority and any industrial concern whereby
an industrial waste of unusual strength or character may be accepted
by the Town or other public authority for treatment, subject to payment
therefor by the industrial concern.
