Where necessary in the opinion of the Superintendent, the owner shall provide, at his/her expense, such preliminary treatment as may be necessary to (1) reduce the biochemical oxygen demand to three hundred (300) parts per million by weight, or (2) reduce the suspended solids to three hundred fifty (350) parts per million by weight, or (3) control the quantities and rates of discharge of such waters or wastes. Plans, specifications, and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Superintendent and no construction of such facilities shall be commenced until said approvals are obtained in writing.
No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes, if it appears likely in the opinion of the Superintendent that such wastes can harm either the sewers, sewage treatment process or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property, or constitute a nuisance. In forming his/her opinion as to the acceptability of these wastes, the Superintendent will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant, and other pertinent factors. The substances prohibited are:
Any liquid or vapor having a temperature higher than one hundred fifty degrees Fahrenheit (150° F) (sixty-five degrees Centigrade (65° C)).

Any waters or wastes containing strong acid iron pickling wastes or concentrated plating solutions whether neutralized or not.
Any waters or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Superintendent for such materials.
Any waters or wastes containing phenols or other taste- or odor-producing substances, in such concentrations exceeding limits which may be established by the Superintendent as necessary, after treatment of the composite sewage, to meet the requirements of the State, Federal, or other public agencies of jurisdiction for such discharge to the receiving waters.
Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable State or Federal regulations.
Any waters or wastes having a pH in excess of 9.5.
Materials which exert or cause:
Unusual concentrations of inert suspended solids (such as, but not limited to, fuller's earth, lime slurries and lime residue) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate).
Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions).
Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
Unusual volume of flow or concentration of wastes constituting "slugs" as defined herein.
Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such degree that the sewage treatment plant affluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
If any waters or wastes are discharged, or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in Subsection (D) of this Section, and which in the judgment of the Superintendent may have deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Superintendent may:
Reject the wastes,
Require pre-treatment to an acceptable condition for discharge to the public sewers,
Require control over the quantities and rates of discharge, and/or
Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of Subsection (J) of this Section.
If the Superintendent permits the pre-treatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Superintendent and subject to the requirements of all applicable Codes, ordinances and laws.
Grease, oil and sand interceptors shall be provided when in the opinion of the Superintendent they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand or other harmful ingredients, except that such interceptors shall not be required for private living quarters or dwelling units.
All interceptors shall be of a type and capacity approved by the Superintendent and shall be located as to be readily and easily accessible for cleaning and inspection.
Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his/her expense.
When required by the Superintendent, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessible and safely located, all be constructed in accordance with plans approved by the Superintendent. The manhole shall be installed by the owner at his/her expense and shall be maintained by him/her so as to be safe and accessible at all times.
All measurements, tests and analyses of the characteristics of water and wastes to which reference is made in this Chapter shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater", published by the American Public Health Association, and shall be determined at the manhole provided or upon suitable samples taken at said 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. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. (The particular analyses involved will determine whether a twenty-four (24) hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from twenty-four (24) hour composites of all outfalls, whereas pHs are determined from periodic grab samples.)
No statement contained in this Article 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, therefore, by the industrial concern.
Grease interceptors shall be provided on kitchen drain lines from institutions, hotels, restaurants, school lunch rooms and other establishments from which relatively large amounts of grease may be discharged to the treatment facility.
Grease interceptors should be located as close to the fixtures being served as possible and should receive only the waste streams from grease producing fixtures. Sanitary waste streams, garbage grinder waste streams and other waste streams which do not include grease should be excluded from passing through the grease interceptors. This separation is mandatory for new construction. Grease interceptors must be cleaned on a regular basis and must be readily accessible for this purpose.
Sizing for grease interceptors is based on wastewater flow and can be calculated from the number and kind of sinks and fixtures discharging to the interceptor. The following two (2) equations shall be used to determine the capacity of grease interceptors for restaurants and other types of commercial facilities:
Restaurants. Forty (40) gallons capacity for each seat, minimum size of one thousand (1,000) gallons.
Hospitals, nursing homes, other type commercial kitchens with varied seating capacity. Fifteen (15) gallons capacity for each meal served per day, minimum size of one thousand (1,000) gallons.
Grease interceptors shall be provided with a manhole or opening of sufficient size to permit inspection and cleaning. When the grease interceptor is located below ground, the access opening shall be extended to grade. The opening shall be fitted with a tight fitting cover which shall prevent the entrance of insects and vermin.
The grease interceptor should be constructed of materials similar to septic tanks and be properly baffled on both the inlet and outlet.
Grease interceptors shall be cleaned on a regular basis. Minimum frequency of cleaning shall be once each six (6) months. Frequency of cleaning shall be determined by regular measurements of the thickness of the floating grease layer. Cleaning should take place in accordance with the interceptor manufacturer's instructions, when the bottom of the floating grease layer approaches within six (6) inches of the interceptor outlet elevation or when the sludge layer approaches within twelve (12) inches of the interceptor outlet elevation, whichever comes first.
Grease interceptors shall not discharge prohibited substances as defined in Article V, Sec. 4(b) in any single event as determined by a grab sample.
Sewage Grinder Pumps.
Individual customer grinder pumps connected to force mains shall be of the positive displacement type of sufficient capacity and horsepower to deliver ten (10) gallons per minute for any residence or duplex. Individual customer grinder pumps connected to gravity sewers may be positive displacement or centrifugal type.
Operation and maintenance of a grinder pump is the sole responsibility of the property owner. Should the City of Rogersville or any developer install City-approved pumping facilities that change the operating pressure of the force main and modifications to individual customer grinder pumps connected to that line are needed, such modifications are the sole responsibility of the owner of the grinder pump.
The property owner shall ensure that their electrical service is adequate for operation of the grinder pump.
All grinder pumps shall be equipped with the following minimum features:
Grinder pump systems shall be complete factory-built and tested grinder pump stations, each consisting of a grinder pump mounted in a pump basin with pump removal system, a shut-off valve, anti-siphon valve and check valve.
Inlet and discharge piping shall be a minimum of forty-two (42) inches below finish grade.
Pump basins shall have a minimum of fifty (50) gallons capacity below the inlet line.
The cover or lid shall be locked and withstand a minimum live load of three hundred (300) pounds per square foot.
Concrete ballast shall be placed around the basin to prevent flotation in high ground water conditions.
One (1) additional check valve shall be installed on the owner's property near the connection to the force main. This valve shall be installed in a cast iron slide type valve box.
A remote electrical panel with audio alarm, visual alarm and disconnect shall be mounted within sight of the grinder pump unit.
