[11-22-1983, § 11]
All applicants who desire to discharge sewage in excess of 5,000 gallons per day, industrial wastewaters and/or cooling waters to the New Milford Sewage Treatment Plant must first obtain a permit from the Department of Environmental Protection under the provisions of § 25-54i of the Connecticut General Statutes, and a copy of such permit must be filed with such applicant's application for a sewer connection permit.
[11-22-1983, § 12]

[11-22-1983, § 13; 7-16-1984]
Upon approval of a sewer permit application and the payment by the applicant to the Sewer Commission of a nonrefundable sewer connection charge, the applicant is authorized to construct the building sewer in accordance with the sewer plan, as filed, and subject to the requirements set forth in the Town ordinances and regulations governing sewer use. The sewer connection charge shall be paid to the Sewer Commission when the sewer permit application is filed with the Commission.
[11-22-1983, § 14; 7-16-1984]
(a) 
Approval of a sewer permit application shall automatically lapse 90 days after the date of the approval of the application unless a written extension is granted by the Sewer Commission prior to the expiration of said ninety-day period. Within such time period, the applicant must construct the sewer, complete the connection to the sewer line and obtain the connection permit. A connection permit shall be issued only after all such work, including the actual connection to the sewer line, has been inspected and approved by the Sewer Commission. Upon issuance of a connection permit, the applicant shall be billed for, and shall be obligated to pay, the sewer use charges, regardless of discharge.
(b) 
Once an approval has lapsed, the applicant will be required to submit a new sewer permit application to the Sewer Commission for approval and to pay a new sewer connection charge as required by § 22-45 hereof before further authorization to construct and connect the building sewer will be granted. All work on the construction of the building sewer shall immediately cease whenever the sewer permit under which it is being performed has lapsed.
[11-22-1983, § 15]
For multifamily buildings, the Sewer Commission may require the installation of a separate and independent building sewer for each dwelling unit. Otherwise, a separate and independent building sewer shall be provided for every building.
[11-22-1983, § 16]
Existing building sewers may be used in connection with new buildings only when they are found, on examination and testing by the Sewer Commission, to meet all requirements of these regulations and only with a written permit from the Sewer Commission.
[11-22-1983, § 17]
The size and slope of the building sewer shall be subject to the approval of the Sewer Commission, but in no event shall the diameter be less than six inches. The slope of such six-inch pipe shall not be less than 1/8 inch per foot.
[11-22-1983, § 18]
Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. No building sewer shall be laid parallel to or within three feet of any bearing wall, which might thereby be weakened. The depth shall be sufficient to afford protection from frost. The building sewer shall be laid at a uniform grade and in a straight alignment insofar as possible. Changes in direction shall be made only with properly curved pipes and fittings.
[11-22-1983, § 19]
In all buildings in which a building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such drain shall be lifted by an approved artificial means and discharged to the building sewer. Duplex lift systems shall be provided for commercial and industrial buildings.
[11-22-1983, § 20]
No building sewer shall be constructed within 25 feet of a water supply well. If a building sewer is constructed within 25 to 75 feet of a water supply well, it shall be constructed in accordance with all applicable guidelines promulgated by the Commissioner of Environmental Protection.
[11-22-1983, § 21]
The size, slope, alignment, materials of construction of a building sewer and the methods to be used in excavating, placing of the pipe, jointing, testing and backfilling the trench and connection of the building sewer to the public sewer shall all conform to the requirements of the Building and Plumbing Code or other applicable rules and regulations of the Town of New Milford. In the absence of code provisions or in amplification thereof, the materials and procedures set forth in appropriate specifications of the American Society for Testing and Materials and Water Pollution Control Facility Manual of Practice No. 9 shall apply.
[11-22-1983, § 22]
All excavations required for the installation of a building sewer shall be open trench work, unless otherwise approved by the Sewer Commission. No trench containing a building sewer shall be backfilled until the Sewer Commission has completed an inspection of and approved the work. The water level in the trench shall be maintained at a level below the building sewer, and no connection into the public sewer shall be made until such time as the building sewer and connection has been inspected, approved and backfilled. Special fittings may be used for the connection of the building sewer to the public sewer only when approved by the Sewer Commission or its authorized agent.
[11-22-1983, § 23]
The applicant for the building sewer permit shall notify the Sewer Commission when the building sewer is ready for inspection and connection to the public sewer. The connections shall be made under the supervision of the Sewer Commission or its authorized agent.
[11-22-1983, § 24]
All excavations for building sewer installations shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the Town.
[11-22-1983, § 25]

[11-22-1983, § 34]
Where pretreatment, flow-equalizing or off-peak-discharge facilities are provided or required for any sewage, such facilities shall be maintained by the owner, at his expense, continuously and in satisfactory and effective operating condition.
[11-22-1983, § 35]
When required by the Sewer Commission, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable structure, together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such structure, when required, shall be accessible and safely located and shall be constructed in accordance with plans approved by the Sewer Commission. The sampling structure shall be located at a point along the industrial waste stream where a representative sample of the industrial wastewater may be obtained prior to its being diluted by domestic sewage in the building sewer. The structure 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.
[11-22-1983, § 36]
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in these regulations shall be made and determined in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association.
