Except as specifically provided, in writing, with reference to a particular sewer connection, sanitary sewers shall be used only for the conveyance and disposal of sanitary sewage as defined in these regulations and for diluted, water-carried industrial wastes which are not objectionable, as provided hereinafter. Any use of the sanitary sewers for diluted, water-carried industrial wastes shall require the prior, explicit approval of the Board, in writing.
Any person proposing a change in the volume of sewage discharged into the system or a substantial change in the character of pollutants that are being discharged into the system shall file an application for sewer service, and no such new discharge or change may occur until the Board has approved the application. A change in use may result in a sewer surcharge or connection fee.
No person or party shall discharge or put into any public sewer of the Town of Kingston, or into any sewer or fixture which thereafter discharges into any public sewer or appurtenance thereof, any waste or substance other than such kinds or types of water or water-carried wastes for the conveyance of which the particular sewer or appurtenance is intended and designed.
Excepting wastes which a particular sewer was originally authorized by the Town to convey, discharges of other wastes shall not be permitted, unless the Board shall have amended the original designation in writing. Any customer found to be discharging unauthorized wastes shall be subject to penalties and fees.
No sanitary sewer shall be used to receive and convey or dispose of any stormwater or surface water, subsoil drainage, water seeping into buildings or excavations from soils or other underground sources, flows of natural springs or groundwater, surplus from flowing wells, the discharge from swimming pools, roofs, roof conductors, yard drains, basement drains and sumps, or street or highway drains.
The Board may allow the disposal of septage at the plant. Septage shall not be disposed of into the sanitary sewer except with the advance approval of the Superintendent.
All charges for sewer service shall be made in accordance with the Schedule of Rates on file with the Wastewater Department. The owner of the property shall be liable for the payment of the sewer use charges for such building.

If any sanitary sewage and/or wastewaters are discharged, or are proposed to be discharged, to the public sewers, which sanitary sewage and/or wastewaters contain the substances or possess the characteristics enumerated in this article and which, in the judgment of the Superintendent, may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance or create an additional volume of flow in the sanitary sewer of groundwater, stormwater, surface water, roof runoff and subsurface drainage (including, but not limited to, discharge from basement sumps), the Superintendent may:
A. 
Reject the sanitary sewage and/or wastewaters;
B. 
Require pretreatment to an acceptable condition for discharge to the public sewers;
C. 
Require control over the quantities and rates of discharge; and/or
D. 
Require payment to cover the added cost of handling and treating the wastes not covered by existing sewer charges.
In determining whether any substance discharged or proposed to be discharged into any public sewer is to be excluded under any section of these regulations, consideration shall be given to the quantity, time or times, rate and manner of discharge, character of the sanitary sewage and/or wastewater in question, the size of the sewer into which it is, or is to be, discharged, the probable quantity of other sewage in said sewer at the time of discharge, the quantities of other objectionable substances likely in said sewer, and other pertinent facts.
A. 
Minute quantities of a substance that would be objectionable in larger quantity may be permitted, upon specific advance approval from the Superintendent, if the quantity discharged is very small in comparison to the receiving sewer and the flow therein at the time of discharge.
B. 
Exceptions will be determined on an individual basis. Any permission to discharge minute quantities of an otherwise excluded substance shall be revocable at any time by the Superintendent.
If the Superintendent permits the pretreatment or equalization of sanitary sewage and/or wastewater 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.
A. 
The attempt to achieve compliance with the discharge limitations of these regulations by increased dilution, including increased use of process water as a substitution for adequate treatment, is prohibited.
B. 
Any use of the sanitary sewers for diluted, water-carried industrial wastes shall require the prior, explicit approval of the Superintendent, in writing.
C. 
All such plants and equipment shall be maintained continuously in satisfactory and effective operation by the owners at their expense. In maintaining such plants and equipment, the owner shall be responsible for the proper removal and disposal by appropriate means of any residue and shall maintain records of the dates and means of disposal which are subject to review by the Town. Licensed waste disposal firms must perform any removal and hauling of the collected materials not performed by the owner.
At all premises where substances specified to be excluded from sewers by these regulations, and including but not limited to liquid wastes containing grease in excessive amounts, or any flammable wastes, sand, or other harmful ingredients, are customarily present and liable to be discharged directly or indirectly into any sanitary sewer, suitable and sufficient piping layouts, sand, oil or grease traps or separators, screens, sedimentation chambers, storage and regulating treatment, cooling or condensing equipment and similar devices or equipment shall be provided, maintained and operated to ensure that no substance required to be excluded from the sewer shall be discharged thereunto in violation of the requirements of these regulations. All restaurants and institutional kitchens shall be required to have an approved grease trap or grease removal system. Each gas station shall have an approved fuel trap. Each car wash shall have an approved sand trap.
A. 
All such equipment and devices 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.
B. 
The owner(s) shall be responsible for maintaining these devices and for the proper removal and disposal by appropriate means of the captured material and shall maintain written records of the dates, and means of disposal, which records are subject to inspection by the Superintendent or an authorized representative. Currently licensed waste disposal firms must perform any removal and handling of the collected materials not performed by the owner's employees. Written records shall be provided to the Sewer Commission quarterly.
C. 
In the case of groundwater, stormwater, surface water, roof runoff and subsurface drainage (including, but not limited to, discharge from basement sumps), proper connection to the Town's stormwater drainage system, where allowable, is considered a protective device.
When required by the Superintendent, the owner of any property having a service connection carrying industrial wastewater shall install a suitable control manhole, together with such necessary meters and other appurtenances, in the service connection to facilitate observation, sampling and measurement of the waste stream. 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 the owner's expense, and shall be maintained by the owner so as to be safe and accessible at all times.
All measurements, tests and analyses of the characteristics of sanitary sewage and/or wastewater to which reference is made in these regulations 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 control manhole provided or upon suitable samples taken at said control manhole.
A. 
In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the sewer to the point at which the service connection is made.
B. 
Sampling shall be carried out by customarily accepted methods to reflect the effect of wastewater constituents on the sewage works and to identify any hazards to life, limb and property. (The particular analyses involved will determine whether a twenty-four-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-hour composites of all outfalls, whereas pH is determined from periodic grab samples.)
All industries discharging into the sewer shall perform such monitoring of their discharges as the Superintendent and/or other duly authorized agents of the Town may reasonably require, including installation, use and maintenance of monitoring equipment, keeping records and reporting the results of such monitoring to the Superintendent. The Superintendent shall make such records available upon request to other agencies having jurisdiction over discharges to the receiving waters. Included, but are not limited to, the following:
pH
Temperature
Color
Specific conductance
Total solids
Total volatile solids
Total suspended solids
