§ 281-45. Connections to sanitary sewers and stormwater drains.

A. 

Service lines.

(1) 

The installation and repair of sewer and drainage service lines within the limits of any public street, highway, easement or other public property, and the connection of such service lines to the sanitary sewers and stormwater drains of the City shall be done in accordance with the provisions of the rules and regulations of the Department of Public Works and shall also conform to such specifications as may be promulgated by the Commissioner.

(2) 

A sewer service line, between its connection point at the sanitary sewer and building, shall be a heavy cast-iron pipe with lead joints or such other approved types of joints as may be allowed by the Plumbing Code of the City of New Rochelle and shall be laid by a licensed plumber.

(3) 

A drainage service line between its connection point at the stormwater drain and the property line shall be of heavy cast-iron pipe with lead or other approved joints, reinforced concrete or other pipe approved by the Commissioner.

(4) 

Such service lines shall be laid on a straight alignment and uniform gradient of not less than 1/4 inch per foot unless otherwise specifically authorized by the Director and having all changes in direction made with approved fittings.

B. 

Restriction as to type or amount of discharge.

(1) 

No domestic sewage nor industrial wastes and no injurious waste substance shall be discharged into a stormwater drain, watercourse or body of water through any connection thereto.

(2) 

No industrial wastes nor any injurious waste substance shall be discharged into a sanitary sewer unless the method and degree of treatment, prior to discharge, have been approved by the Commissioner of Public Works of Westchester County and unless such method and degree of treatment continue at all times to meet with such approval.

(3) 

Subject to the prior approval of the Commissioner, waste lines from a swimming pool shall be connected into a sanitary sewer, and discharge of wastewater from a swimming pool into the sanitary sewer shall be restricted to the period between 12:00 midnight and 6:00 a.m. The size of the discharge line at the point of connection shall not, in general, exceed four inches, and may be further reduced by the Commissioner at the latter's discretion.

C. 

Connections.

(1) 

Except as otherwise provided hereinbelow, connections to sanitary sewers and stormwater drains shall be made by means of forty-five-degree or ninety-degree M-D Cut-In Connections of approved size as manufactured by Joseph G. Rollard Co., Inc., or an approved equal.

(2) 

The use of an existing Y-branch, or other existing fitting, for the purpose of connecting a service line thereto shall be allowed only when such branch or fitting is already available and in place as a part of a sanitary sewer or stormwater drain, is in satisfactory condition and at an acceptable location and is of adequate size to receive said service line

(3) 

Whenever the proposed service line is greater than four inches when the sanitary sewer or stormwater drain is six inches or less; or greater than five inches, when the sanitary sewer or stormwater drain is eight inches or less; or greater than six inches when the sanitary sewer or stormwater drain is 10 inches or less, a manhole shall be built over said sanitary sewer or stormwater drain at the point of connection unless otherwise specifically authorized by the Commissioner. The above sizes refer to the internal diameter of the pipe or conduit.

(4) 

M-D Cut-In Connections and other approved types of connections shall be installed in such a manner that the invert of said connection shall be higher than the invert of the sanitary sewer or stormwater drain by an amount not less than 1/2 the vertical diameter of said sanitary sewer or not less than 3/4 of the vertical diameter of said stormwater drain, unless otherwise authorized by the Commissioner.

(5) 

Connections to an existing cast-iron pipe sanitary sewer or stormwater drain shall be made by burning an opening in said pipe in an approved manner or by such other means as may be authorized by the Commissioner.

(6) 

When a connection is made into an existing manhole or when a manhole is required to be built at the point of connection, as specified hereinabove, the invert of the service line at the point of connection shall be higher than the invert of the sanitary sewer or stormwater drain by an amount not less than the vertical diameter of said sanitary sewer or stormwater drain, unless otherwise authorized by the Commissioner.

(7) 

When the difference in invert elevation in the manhole at the point of connection exceeds three feet, a drop connection shall be installed in said manhole.

(8) 

Adequate provision shall be made so that the discharge from a service line within a manhole shall be conducted smoothly into and in the direction of flow of the main channel of the sanitary sewer or stormwater drain by means of a built-up channel or by extending said service line partly into the manhole, as may be necessary and in such manner as may be approved by the Commissioner.

(9) 

Construction of new manholes, drop connections and any other necessary structures, and connections to existing structures, shall conform to such specifications as may be promulgated by the Commissioner; in general, the current standard specifications and construction details of the Department of Public Works shall be followed subject to the prior approval of the Commissioner.

(10) 

In the event that the sewer or drain connection is not installed under the supervision and the approval of the Commissioner's authorized personnel, the permittee shall forfeit the deposit, and the Commissioner shall have the authority to deny said permittee of any future permit.

D. 

Drainage from business, commercial, industrial and other buildings.

(1) 

Roof and other drainage from properties on which buildings are hereinafter constructed to be used in whole or in part for business, commercial, industrial or other public purposes shall be discharged through drainage service lines directly into a stormwater drain through an approved connection thereto when such a stormwater drain is available and unless such connection, in the opinion of the Commissioner, is deemed impracticable.

(2) 

Discharge of such drainage through sidewalk or curb drains and discharge of roof or other drainage from any privately owned buildings or properties into a catch basin will not be allowed except with the prior approval of the Commissioner, and provided that the owner of said property has filed with the Commissioner a signed statement by said owner that the City of New Rochelle is to be saved harmless from any loss, injury or damage arising out of the approval of the Commissioner of the discharge of drainage into a catch basin or through sidewalk or curb drains.

E. 

Sidewalk and curb drains.

(1) 

Unless otherwise authorized in writing by the Commissioner, drainage outlets laid under or across the sidewalk area between the property line and the curbline, and discharging into the gutter or into a catch basin or curb inlet, shall be approved cast-iron or steel construction.

(2) 

When holes are cut through curbs for the purpose of providing drainage outlets, care shall be taken not to damage the curb, and any damage or injury to said curb shall be repaired by the permittee at the latter's own expense and to the satisfaction of the Commissioner.
