[HISTORY: Adopted by the Town Board of the Town of Mount Pleasant 3-25-1969 as Ch. 33 of the 1969 Code. Amendments noted where applicable.]
As used in this chapter, the following terms shall have the meanings indicated:
- Any discharge of water, sewage or industrial waste which, in the concentration of any given constituent or in the quantity of flow, exceeds, for any period of duration longer than 15 minutes, more than five times the average twenty-four-hour concentration of flows during normal operation.
No person shall discharge or cause the discharge of any harmful or deleterious substance to any public sanitary sewer or sewage disposal system so as to endanger the use of or the materials of construction of such sewer or the sewage treatment plant or system or so as to result in the stoppage or other failure of the sewerage system or subsequent sewage treatment.
The town and all users of the town sanitary sewer system shall be subject to all applicable rules and regulations in the Westchester County Environmental Facilities Sewer Ordinance No. 1, as amended.
No person shall throw or deposit or cause to be thrown or deposited into any drain, catch basin, sewer or gutter within the town any substance which may cause obstruction or injury thereto or nuisance therein. It shall also be unlawful for any person to divert or stop the flow of any drain or sewer.
The owner of any habitable building or property used for human occupancy, employment, recreation or other purpose, abutting upon any street or right-of-way in which there is located a public sanitary sewer, shall be required to install, at the expense of such owner, suitable toilet facilities therein and to connect such facilities directly with the public sanitary sewer by means of a sewer spur provided by the town or by a new connection installed as specified in this chapter if a town spur is not available, all as directed by the Town Board, within 90 days after the date of an order, in writing, issued by the Town Board to so do, provided that such sewer is within 200 feet of any property line of such premises and is otherwise accessible.
No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary sewer.
Stormwater and all other unpolluted drainage shall be discharged to storm sewers or to a natural outlet approved by the Town Engineer or House Sewer Inspector. Industrial cooling water or unpolluted process waters may be discharged, on approval of the Town Engineer or House Sewer Inspector, to a storm sewer or natural outlet.
No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the sewage treatment plant, including but not limited to cyanides in excess of two milligrams per liter as CN in the wastes as discharged to the public sewer.
Any waters or wastes having a pH lower than 5.5 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewerage works.
Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewerage works, such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, ungrounded garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
No person shall discharge or cause to be discharged the following described substances, materials, waters or waste if it appears likely in the opinion of the Town Engineer or House Sewer Inspector 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, property or constitute a nuisance. In forming his opinion as to the acceptability of these wastes, the Town Engineer or House Sewer Inspector 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 150° F. (54° C.).
Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of 100 milligrams per liter, or containing substances which may solidify or become viscous at temperatures between 32° F. and 150° F. (0° C. and 65° C.).
Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of 3/4 horsepower (0.76 horsepower metric) or greater shall be subject to the review and approval of the Town Engineer or House Sewer Inspector.
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 Town Engineer or House Sewer Inspector for such materials.
Any waters or waste containing phenols or other taste- or odor-producing substances in such concentrations exceeding limits which may be established by the Town Engineer or House Sewer Inspector 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 Town Engineer or House Sewer Inspector 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 residues) 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 effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
Disposition of wastes.
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 Town Engineer or House Sewer Inspector, may have a deleterious effect upon the sewerage works, processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Town Engineer or House Sewer Inspector may:
Reject the wastes;
Require pretreatment 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.
If the Town Engineer or House Sewer Inspector permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Town Engineer or House Sewer Inspector 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 Town Engineer or House Sewer Inspector, 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 Town Engineer or House Sewer Inspector 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 expense.
When required by the Town Engineer or House Sewer Inspector, 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 accessibly and safely located and shall be constructed in accordance with the plans approved by the Town Engineer or House Sewer Inspector. 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 this chapter shall be determined in accordance with the latest edition of Standard Methods for the Examination of 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. 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 sewerage works and to determine the existence of 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's are determined from periodic grab samples.)
All connections to the sanitary sewers in the Town of Mount Pleasant shall conform to the following requirements:
Before any work is commenced, an application for a connection permit shall be filed with the Town Engineer or House Sewer Inspector on a form provided by him for that purpose, accompanied by an application fee as set forth in Chapter A224, Fees, and a connection permit issued by the Town Engineer or House Sewer Inspector shall be obtained therefor.
All work shall be performed by or under the immediate supervision of a plumber duly licensed by the Town of Mount Pleasant. The person so licensed to make such connection or opening shall comply with and be responsible for the following:
No obstruction of any description whatever shall be left in the connection.
Unless otherwise approved by the Town Engineer or House Sewer Inspector, a minimum separation of three feet on centers shall be maintained between the house sanitary connection and the house water service, and the waterline shall be at an elevation 18 inches higher than the sewer line if laid within 10 feet of the sewer line.
Any damage or injuries that may accrue to persons, animals or property by reason of any opening in any street or right-of-way made by them or those in their employ.
The applicant for the building sewer permit shall notify the Town Engineer or House Sewer Inspector a minimum of 24 hours prior to when the building sewer is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of a plumber licensed by the Town of Mount Pleasant. No work shall be covered until inspected by the Town Engineer or House Sewer Inspector or his representative. All excavations for building sewer installations shall be adequately guarded with barricades and lights so as to protect the public from hazard. Proper shoring shall be provided where necessary to avoid cave-ins into trench excavations. At time of connections to a public sewer, any septic tanks, cesspools and similar private sewage disposal facilities shall be abandoned, pumped out and filled with suitable inert material. Under no circumstances shall said sanitary waste material be disposed of into town sanitary sewers.
All excavations shall be refilled and the earth rammed and the pavement taken up shall be suitably restored, and should it settle or become out of order within 12 months thereafter and the owner or plumbing contractor shall neglect to repair the pavement aforesaid within 24 hours after being notified, the Town Superintendent of Highways may cause the same to be done and charge the expense thereof to such licensee.
Each permit shall have endorsed thereon the contents of § 149 of the Highway Law of the State of New York, and the licensee and owner of the land benefited by the sewer connection shall be deemed to have accepted such permit or the issuance of the same on the condition that there will be full compliance with the provisions of said section and that such persons will be bound thereby.
The line running from the house or other building to the sanitary sewer shall be of not less than four inches extra-heavy cast iron and shall be thoroughly caulked and joined with first-quality lead and oakum. Unless loading conditions as determined by the Town Engineer or House Sewer Inspector warrant additional pipe strength, it shall be permissible to use asbestos-cement building sewer pipe in lengths not to exceed five feet in lieu of extra-heavy cast iron pipe, provided that such pipe shall have a crushing strength of at least 1,500 pounds per linear foot when tested in accordance with ASTM designation C-14, three-edge bearing method. Such pipe shall not be laid directly on a rock base but shall be cushioned by a minimum four-inch-thick layer of clean sand.
Each building other than accessory buildings incidental to the principal building or structure on each parcel of property shall have a separate connection with the sewer, except that in the case of real estate developments containing one or more private streets supplied with lateral sewers privately constructed, each building other than accessory buildings incidental to the principal building or structure on each parcel of property shall have a separate connection either with such lateral sewer or with the town sewer. Any such lateral sewer privately constructed shall be constructed in accordance with the standards of this chapter and shall be properly maintained at all times.
Any person who shall violate or fail, neglect or refuse to comply with any provision of this chapter or any rule. regulation, order or special direction duly made thereunder shall, upon conviction thereof, be punished by a fine of not more than $250 or by imprisonment not exceeding 15 days, or by both such fine and imprisonment, and each week such violation shall continue shall constitute a separate offense.
This chapter shall be enforced by the Town Engineer or House Sewer Inspector.
