(2) Note: No building shall be considered less than 1.00
unit. If any residential, commercial or industrial facility is not
noted on this listing, the Water and Sewer Department, or City Manager
shall determine the appropriate unit charge for that building.
All costs and expenses incident to the installation
and connection of a building sewer shall be borne by the owner of
the property. The owner shall indemnify the City from all loss or
damage that may directly or indirectly be occasioned by the installation
of the building sewer.
All applicants for sewer connection permits
shall first submit plans and specifications of all plumbing construction
within the building or premises, and such plans and specifications
shall meet the requirements of the Michigan Plumbing Code, as adopted
in Chapter
171 of the Code of the City of Rockwood. When such plans
and specifications have been approved by the Building Official a construction
permit shall be issued, subject to final inspection and approval when
construction is completed and ready for connection with the City sewerage
system.
The applicant for a building sewer permit shall
notify the Building Official when the building sewer is ready for
inspection and connection to the public sewer. The Building Official
shall then inspect the building and plumbing construction therein,
and if such construction meets the previous requirements as approved
in the construction permit, a sewer connection permit shall be issued,
subject to the applicable provisions of this chapter.
The cost of repair, maintenance and replacement
of existing building sewers and their connection to public sewers
shall be borne by the property owner. Such owner shall make application
to perform such work to the Director of Public Works.
Except as hereinafter provided, no person shall
discharge any commercial-type waste into the City sewerage system,
which waste is deleterious to the public health and safety. Any waste
will be considered deleterious if it may cause damaging effects as
stated in Subsection A hereof and/or if it does not conform to the
limitations stated in Subsection B hereof.
A. General conditions. Waste that causes any of the following
will be considered deleterious to the sewage system:
(1) Chemical reaction, either directly or indirectly,
with the materials of construction, so as to impair the strength or
durability of sewer structures;
(2) Mechanical action that will destroy or damage sewer
structures;
(3) Restriction of the hydraulic capacity of sewer structures;
(4) Restriction of the normal inspection or maintenance
of sewer structures;
(5) Placement of unusual demands on the sewage treatment
equipment or process;
(6) Limitation of the effectiveness of the sewage treatment
process;
(7) Danger to public health and safety; or
(8) Obnoxious conditions inimical to the public interest.
B. Specific conditions.
(1) Acidity or alkalinity must be neutralized to a pH
of 7.0 as a daily average on a volumetric basis, with a maximum temporary
variation of pH 5.0 to 10.0.
(2) Wastes must not contain more than 10 ppm of hydrogen
sulfide, sulfur dioxide, oxides of nitrogen or any of the halogens.
(3) Wastes must not contain any explosive substance.
(4) Wastes must not contain any flammable substance with
a flash point lower than 187° F.
(5) Wastes must have a temperature within the range of
32° to 150° F.
(6) Wastes must not contain grease, oil or any other substance
that will solidify or become viscous at temperatures between 32°
and 150° F.
(7) Wastes must not contain an insoluble substance in
excess of 10,000 ppm or exceeding a daily average of 500 ppm.
(8) Wastes must not contain total solids (soluble and
insoluble substances) in excess of 20,000 ppm or exceeding a daily
average of 2,000 ppm.
(9) Wastes must not contain soluble substances in concentrations
that would increase the viscosity to greater than 1.1 specific viscosity.
(10)
Wastes must not contain insoluble substances
having a specific gravity greater than 2.65.
(11)
Wastes must not contain insoluble substances
that will fail to pass a No. 8 standard sieve, or that have any dimension
greater than 1/2 inch.
(12)
Wastes must not contain gases or vapors, either
free or occluded, in concentrations that are toxic or dangerous to
humans or animals.
(13)
Wastes must not have a chlorine demand greater
than 15 ppm.
(14)
Wastes must not contain more than 100 ppm of
any antiseptic substance.
(15)
Wastes must not contain phenols in excess of
.005 ppm.
(16)
Wastes must not contain any toxic or irritating
substance which will create conditions hazardous to public health
and safety.
(17)
Wastes must not contain in excess of 100 ppm
or exceed a daily average of 25 ppm of any grease, oil or oily substance.
C. All of the preceding standards and regulations shall
apply at the point where commercial-type wastes are discharged into
a public sewer, and all chemical and/or mechanical corrective treatment
must be accomplished to practical completion before this point is
reached.
Where preliminary treatment facilities are provided
for waters or wastes, they shall be maintained in satisfactory and
effective operation by the owner, at his or her expense.
When required by Council or the State Department
of Natural Resources, 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 measurement of wastes. Such manhole, when required, shall be accessibly
and safely located, and shall be constructed in accordance with plans
approved by Council. The manhole shall be installed by the owner,
at his or her expense, and shall be maintained by him or her 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
§
254-12 shall be determined at the control manhole provided
for in §
254-15, or upon suitable samples taken at such
control manhole. If 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 chapter shall
be construed as preventing any special agreement or arrangement between
the City and any industrial concern whereby an industrial waste of
unusual strength or character may be accepted by the City for treatment,
subject to payment by the industrial concern of the estimated cost
of such treatment.
No unauthorized person shall maliciously, willfully
or negligently break, damage, destroy, uncover, deface or tamper with
any structure, appurtenance or equipment which is a part of the municipal
sewerage system or treatment plant.
[Amended 4-16-1997 by Ord. No. 348]
A. Purpose. The purpose of this section is to make it
unlawful for any person to permit or to cause water from the roof
of any building, or storm- or surface water, to be directly connected
by downspouts, pipes, conduits or other device or apparatus to a drain
connected with the sanitary sewer system of the City, it being the
intention of this section to prohibit any person from making, continuing,
or allowing the existence of any type of connection with eave troughs,
sump pumps or other drains on a building with the City's sanitary
sewer system, or any other drain emptying into the City's sanitary
sewer system so as to cause stormwater, surface, subsurface or roof
water from any such building to drain into the sanitary sewer system
through eave troughs, drain pipes, downspouts, sump pumps, conduits
or other devices. This section is declared to be necessary in the
interests of public health, safety and welfare to relieve flooding,
to control pollution and to help minimize the City's cost for charges
for excess flow entering the sewage disposal system.
B. Disconnection. Any downspouts, pipes, conduits, sump
pumps or other device or apparatus capable of carrying stormwater,
surface, subsurface or roof water from a building to a sanitary sewer
or to sewers or drains leading to any sanitary sewer shall be disconnected.
If the owner, lessee, possessor or occupier of any building or structure
has not complied with this section, the Director of Public Works or
his designated representative, or any person so designated by the
Mayor and the Council, shall give written notice to any person who
shall be in violation of this section, requiring the violation to
be corrected forthwith. If the violation is not corrected within 30
days from the date of notice, the Director of Public Works or his
designated representative shall disconnect the downspout or other
device and charge the costs thereof to the sewage bill of the resident
involved.
C. Extensions. It is hereby required that on each building
there shall be provided extensions to the downspouts, pipes or conduits
at the building grade of not less than 72 inches in length and attached
in such a manner as to direct any stormwater, surface or roof water
to the rear of the property or to the street as the case may be, in
order to prevent stormwater, surface or roof water from draining directly
against the building walls, adjacent property or into any sanitary
sewer or drain.
D. Exemption. The owner or the authorized agent of any
owner of any property may make written application to the Department
of Public Works for exemption from the requirements of this section.
The Director of Public Works may waive the requirements of this section,
if the disconnection, because of existing problems with grade or drainage,
causes flooding of the involved property or dwelling, flooding of
adjacent property or dwelling, substantial pooling of water or causes
other such similar conditions to exist. Within 30 days after receipt
of an application for exemption, the Director of Public Works shall,
in writing, notify the applicant of his decision. In granting an exemption,
the Commissioner of Water may require such modification of the drainage
of stormwater, surface or roof water as he deems necessary and appropriate
under the circumstances of each case. Any person denied such exemption
may appeal the same to the Building Code Board of Appeals.
E. Applicability. This section shall apply to all homes,
buildings and structures in the City, or any building using the City's
sanitary sewer system, and any exemptions heretofore granted by the
Director of Public Works or by any other official or board of the
City are hereby declared void and of no effect; provided, however,
that each holder of such a previously granted exemption may reapply
for exemption.
The City Engineer and other duly authorized
officials and employees of the City and agents of the State Department
of Natural Resources bearing proper credentials and identification
shall be permitted to enter upon all properties for the purpose of
inspection, observation, measurement, sampling and testing, in accordance
with this article, at any time during reasonable or usual business
hours. No person shall refuse or obstruct such entry.
No officer, agent or employee shall aid or abet
any violation of this chapter, or, being responsible therefor, refuse
or neglect to take corrective action.
