[Ord. of 1-13-1972, art. IV, § 2]
(a) 
No person shall discharge or cause to be discharged any wastes into a public sewer unless the acceptance of these wastes has been approved by the Blackstone Valley Sewer Commission and the state department of health.
(b) 
The acceptance of any wastes into any sewer shall be in accordance with all rules and regulations established by the Blackstone Valley Sewer Commission, the state department of health, and the Town public works department.
(c) 
It shall be the responsibility of any industrial or commercial plant to furnish the Town Engineer and the director of public works the proportions of the chemical makeup of the wastes that they intend to discharge into the public sewer. If the wastes that they plan to discharge into a public sewer are objectionable to the Blackstone Valley Sewer Commission, the state department of health or the Town public works department, it shall be the applicant's responsibility to take whatever steps required to make them suitable and acceptable to the Blackstone Valley Sewer Commission, the state department of health and the Town public works department. The applicant shall furnish, if requested, samples of the waste, together with a chemical breakdown of what they propose to discharge into the proposed public sewer. This information is to be furnished to any of such agencies so requesting.
[Ord. of 7-8-1976(2), art. XIV, § A]
Any person proposing a new discharge into the system or a substantial change in the volume or character of pollutants that are being discharged into the system shall notify the department of public works at least 45 days prior to the proposed change or connection.
[Ord. of 7-8-1976(2), art. XIV, § B]
No person shall make connection of roof downspouts, exterior foundation drains, arcaway drains, or other sources of surface runoff or groundwater to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer.
[Ord. of 7-8-1976(2), art. XII, § B]
It shall be unlawful to discharge to any natural outlet within the Town or in any area under the jurisdiction of the Town, any sewage or other polluted waters, except where suitable treatment has been provided in accordance with the provisions of this article.
[Ord. of 7-8-1976(2), art. XV, § A]
Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as combined sewers or storm sewers, or to a natural outlet approved by the Town Engineer. Industrial cooling water or unpolluted process waters may be discharged, on approval of the Town Engineer, to a storm sewer, combined sewer, or natural outlets.
[Ord. of 7-8-1976(2), art. XV, § B]
No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(1) 
Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas.
(2) 
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.
(3) 
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 sewage works.
(4) 
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 sewage works such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
[Ord. of 7-8-1976(2), art. XV, § C]
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 Town Engineer 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 opinion as to the acceptability of these wastes, the Town Engineer 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:
(1) 
Any liquid or vapor having a temperature higher than 150° F. (65° C.).
(2) 
Any water or waste containing fats, wax, grease, or oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32 and 150° F. (0 and 65° C.).
(3) 
Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-quarter horsepower or greater shall be subject to the review and approval of the Town Engineer.
(4) 
Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized or not.
(5) 
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 for such materials.
(6) 
Any waters or wastes containing phenols or other taste or odor producing substances, in such concentrations exceeding limits which may be established by the Town Engineer 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.
(7) 
Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Town Engineer in compliance with applicable state or federal regulations.
(8) 
Any waters or wastes having a pH in excess of 9.5.
(9) 
Materials which exert or cause:
a. 
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.
b. 
Excessive discoloration such as, but not limited to, dye wastes and vegetable tanning solutions.
c. 
Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
d. 
Unusual volume of flow or concentration of wastes constituting slugs.
(10) 
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.
[Ord. of 7-8-1976(2), art. XV, § H]
All industries discharging into a public sewer shall perform such monitoring of their discharge as the department of public works and other duly authorized employees 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 department of public works. Such records shall be made available upon request by the department of public works to other agencies having jurisdiction over discharges to the receiving water.
[Ord. of 7-8-1976(2), art. XV, § I]
No statement contained in this article shall be construed as preventing any special agreement or arrangement between the Town and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the Town for treatment, subject to payment therefore, by the industrial concern.
