(a) 
No person shall throw or deposit, or cause to be thrown or deposited, any substance in the sanitary sewer system or any plumbing connection therewith or otherwise dispose of any substance in such manner that it will tend to interfere with the free passage of water or sewage within the sanitary sewer system. Without limiting the foregoing, no person shall discharge or cause to be discharged into the sanitary sewer system or any plumbing connection any of the following described liquids or substances:
(1) 
Any ashes, cinders, sand, mud, straw, wood shavings, metal, glass, concrete, rags, feathers, tar, plastic, fats, oils, greases or any other solid or viscous substance capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sanitary sewer system.
(2) 
Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
(3) 
Waste from a mechanical garbage disposal or grinder used in the operation of any restaurant, market, supermarket, mortuary, hotel, hospital or any other mercantile or business establishment, or multi-family dwelling of three or more units, except by written permission of the sewer engineer.
(4) 
Any water or waste containing corrosive materials of such character and quality as might tend to injure, impair, corrode or damage the sanitary sewer system or sewage treatment plant or any facility or component which is part of the same.
(5) 
Any waste at temperatures above 140° F.
(b) 
No person shall provide for or permit the drainage of any cellar, swimming pool, sump pump, air conditioning system or any storm water, groundwater or surface water, directly or indirectly, into the sanitary sewer system.
(c) 
No water cooled air conditioner shall be connected with the sanitary sewer system. In lieu of draining into the sanitary sewer system, water cooled air conditioners shall be provided with circulating water towers or alternative means of water disposal other than use of the sanitary sewer system.
(d) 
The sewer engineer may, by regulation, further define substances which may be prohibited from disposal in the sanitary sewer system by reason of their tendency to interrupt or interfere with the flow of the sewer, constitute a danger of fire, explosion, asphyxiation or other menace to public safety, or corrode, damage or impair the public sewer, sewage treatment process or other facility thereto. The sewer engineer, upon the request of any user of the sanitary sewer system, shall provide a determination as to whether or not a particular substance may be disposed in the sanitary sewer system; if the sewer engineer shall determine that such substance may be disposed of, provided certain conditions are met by the user, a written permit to use the sanitary sewer system for such disposal subject to the conditions imposed by the sewer engineer, shall be issued by the sewer engineer, and failure to comply with such conditions shall constitute a violation of this article.

(a) 
Grease traps shall be provided by the owner, landlord and/or tenant of all existing and new retail food establishments, delicatessens, restaurants, take-out food establishments, hotel kitchens, bars, factory cafeterias, clubs or other eating establishments (collectively referred to in this section as "establishments"), to prevent the discharge of FOG into the sanitary sewer system.
(b) 
Appropriately sized grease traps shall be installed in accordance with the applicable provisions of the UCC. Notwithstanding the provisions of the UCC, the wash and rinse compartments of a three compartment sink in a food establishment shall be connected to a grease trap. If, due to a change of use or expansion of facilities, an existing grease trap is undersized, the trap must be replaced with an appropriately sized unit.
(c) 
Establishments shall adhere to best management practices dealing with FOG disposal. Each establishment is responsible for ensuring their employees' adherence as well. Best management practices include, but are not limited to, the following:
(1) 
Scraping or dry-wiping FOG and food from pots, pans, utensils and dishware before washing.
(2) 
Using drain screens, as appropriate, to reduce the amount of FOG and other solids entering the grease trap.
(3) 
Disposing of food waste in the garbage or compost, or by other permitted means which do not include disposal in the sanitary sewer system.
(4) 
Ensuring that water hotter than 140° F. does not enter the grease trap.
(5) 
Ensuring that any surfactant, solvent, or emulsifier does not enter the grease trap.
(d) 
Maintenance of grease traps.
(1) 
The walls, baffles, gaskets, and other appurtenances of a grease trap shall be in good working condition. Any grease trap or part thereof that has deteriorated due to corrosion, mechanical distress, or any other cause shall be repaired or replaced if the condition negatively impacts the function of the grease trap as determined by the sewer engineer. Repairs shall be conducted within 30 days of notice from the sewer engineer that said grease trap or one or more parts thereof are defective.
(2) 
Grease traps shall be cleaned as frequently as necessary to ensure the unit is working effectively. At a minimum, grease traps shall be cleaned after 75% of the design storage capacity is reached or once every three months, whichever is more frequent. Grease traps shall be cleaned by fully evacuating the trap of all FOG and other liquids and solids. Side walls and baffle(s) will be scrapped as necessary to remove accumulated debris. FOG shall be disposed of in accordance with applicable local, state, and federal laws and regulations. Care must be taken during cleaning to prevent any FOG from entering the sanitary sewer system. After cleaning, the trap shall be filled with fresh cool water prior to operation. Hot water and enzymatic cleaners shall not be used in the trap as they may cause FOG to bypass the trap and enter the sanitary sewer system.
(e) 
Inspections.
(1) 
The sewer engineer or the engineer's designee shall perform grease trap inspections as often as the engineer or designee deem appropriate, but at least once annually. Upon the request of the sewer engineer or designee, a representative of the establishment must open the grease trap and make accessible the trap and any areas of the facility which may handle FOG.
(2) 
The establishment shall use a cleaning log to document when a grease trap is cleaned, who the grease trap was cleaned by, and the volume of solids removed. At a minimum, the establishment shall maintain records for the preceding twelve-month period. If a third party company is contracted to clean the grease trap, receipts or other proof of service must be kept with the cleaning log. The cleaning log and all applicable receipts must be submitted to the sewer engineer or designee upon request.
(3) 
The sewer engineer or designee may, from time to time, conduct video inspections of sewer mains and sewer laterals. If excess accumulation of FOG is observed in the lateral servicing an establishment, that establishment shall be in violation of this section.
[Added 12-13-2021 by Ord. No. 2021-35]
No cesspool or septic tank shall be allowed to connect to or discharge into the sanitary sewer system.
[Added 12-13-2021 by Ord. No. 2021-35]
The owner of the real property which is, has, or will be served by a sewer lateral is fully responsible for all capital, operational, and maintenance costs and activities necessary for the proper installation, use, and abandonment of the sewer lateral. For properties connected to the public sanitary sewer, such responsibility includes the entire length of the lateral from the building to its point of connection to the public sanitary sewer, inclusive of the fitting connecting the lateral to the public sanitary sewer, and including portions of the lateral located within in the municipal right-of-way or sewer easement, as applicable. For properties connected to a private sanitary sewer, limits of responsibility shall be in accordance any agreement(s) between the property owner and the owner of the private sanitary sewer.

(a) 
Whenever it is determined by the sewer engineer that excessive flow exists in the sanitary sewer system that is not attributable to water usage and such excessive flow is exacerbated by leakage in defective laterals or private sewers, the sewer engineer or designee may inspect the laterals or private sewers. If, on the basis of this inspection, the sewer engineer or designee finds that the excessive flow is caused by a leaking or defective lateral or private sewer, the property owner shall be responsible for repairs or alteration as further set forth in this section.
(b) 
The sewer engineer shall submit to the property owner in writing a detailed specification of work which said engineer deems necessary to reduce or eliminate excessive flow. If the property owner accepts this specification of necessary work, the owner shall:
(1) 
Perform the work at the owner's own expense; or
(2) 
Authorize Princeton to perform the work at the owner's expense, subject to collection as further set forth herein.
(c) 
All work required by this section shall be completed no later than 90 days after receipt by the property owner of a written specification of work from the sewer engineer. The running of the ninety-day period shall be suspended for the months of December, January and February. All such work shall be subject to written approval by the sewer engineer; and no work shall be covered until so ordered by said engineer. Any part of the work covered without the prior consent of said engineer shall be uncovered for examination if so ordered by said engineer.
(d) 
If the property owner refuses or fails to undertake the work, as set forth in the written specification of necessary work, then the sewer engineer shall, on notice to the property owner, undertake such work and assess costs as set forth in subsection (e) below.
(e) 
The costs of any work performed by Princeton or under the direction of the sewer engineer hereunder shall be certified by the sewer engineer to the property owner and to the council. The property owner shall be advised in writing that the certified costs shall be subject to confirmation in the nature of a local improvement at a hearing of the council at a specified date and time. If the certified cost is confirmed by the council to be correct and reasonable, the amount so certified shall, until paid in full by the property owner, become a lien upon the land and shall be added to the taxes to be assessed and levied thereon; and each year thereafter, until the entire amount is paid, one-tenth of such amount with legal interest thereon shall be enforced and collected from the owner of the land, by the same officers and in the same manner as taxes in Princeton. Princeton shall have the same remedies for the collection thereof with costs and penalties as it has by law for the collection of taxes upon real estate.

(a) 
Sump pumps, foundation drains, roof drains, downspout leaders, area drains, and other sources of inflow from groundwater or stormwater shall not be connected in any way, directly or indirectly, to the sanitary sewer system.
(b) 
Upon order of the sewer engineer or designee, the owner of the property on which there is any illicit connection shall take such action as may be reasonably necessary to immediately and permanently disconnect the same, at the owner's sole cost and expense.
(c) 
Prior to the transfer of title of any real property containing a building in which there is a sump pump, foundation drain, roof drain, downspout leaders or area drain, the owner shall obtain a certificate of inflow compliance from the sewer engineer. The certificate may be granted following an in-person inspection of the property by the sewer engineer or the sewer engineer's representative to confirm the absence of illicit connections to the sewer. Ample notice must be given to the sewer engineer to enable the sewer engineer or the sewer engineer's representative to schedule said inspection. The fee for the inspection shall be fifty ($50.00) dollars, which shall be paid by the property owner prior to the inspection. Alternatively, the property owner may elect to submit an affidavit of compliance that the sources of inflow are permanently disconnected from the sanitary sewer system. This affidavit of compliance shall be on forms provided by the sewer engineer's office. The fee for processing said affidavit shall be twenty ($20.00) dollars, which shall be paid by the property owner prior to the issuance of the certificate of inflow compliance.
