§ 109-5. Sewer connection regulations., Chapter 109. Plumbing and Sewers, Code of Ordinances, Hewlett Harbor

Number of connections required. Every building, other than accessory buildings incidental to the principal building or structure on each parcel of property, shall have a separate connection with the public 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 public sewer.

House sewers. House sewers shall be laid solidly on a true grade of not less than one-fourth of an inch per foot. They shall be laid in a straight line. Changes in direction, if necessary, shall be made with proper fittings and all connections made with wye branches and one-eighth or one-sixteenth bends. House sewers shall be covered to a depth of at least two feet with well rammed fine earth free from stones and rubbish.

Materials. The house sewer shall not be less than five-inch-diameter extra-heavy cast-iron pipe or of not less than five-inch-diameter asbestos-cement building sewer pipe.

Joints and connections.

(1)

For cast-iron pipe, all joints shall be firmly packed with oakum or hemp and shall be secured only with pure molten lead, not less than one-foot deep, well caulked.

(2)

For asbestos cement pipe, all joints shall be made with the standard couplings and rubber sealing rings under compression and be made in strict accordance with the manufacturer's standards and recommendations.

Traps. An iron running trap shall be placed in the house drain near the front wall of the house and on the sewer side of all connections. If placed outside the house or below the cellar floor, it must be made accessible by a brick manhole, the walls of which shall be at least eight inches thick and provided with an iron manhole cover. When outside the house, it shall in no case be less than three feet six inches below the surface of the ground. Where fixtures are less than three feet above the public sewer in the street, an approved backwater valve shall be installed. A five-inch-by-four-inch extra-heavy cast-iron wye shall be placed inside the foundation wall and before the house trap. In slab floor or cellarless types of construction, the wye shall be placed outside the house in a pit as decribed in this subsection.

Cleanouts. Cleanouts shall be constructed where required by the Building Inspector.

Grease traps. Grease traps shall be installed as required by the Building Inspector. All connections with grease traps must be of not less than three-inch cast-iron pipe from the sink to the grease trap and of not less than four-inch cast-iron pipe from the grease trap to the house drain.

Vents. A fresh-air inlet pipe shall be connected to the house drain just inside the house trap and extended to the outer air terminating with open end at least 18 inches above the finished grade at the most available point. The fresh-air inlet pipe shall be at least 1/2 the diameter of the house drain, but in no case shall the fresh-air inlet pipe be less than four inches in diameter. No vent caps shall be permitted, and the fresh-air inlet pipe shall terminate with a return bend or a fresh air plate. No curb box or similar device with grating placed in a sidewalk or sidewalk area will be permitted for fresh-air inlets. No building shall be permitted to make any connections with the public sewer unless the building has a soil line extending to a point above the roof and is properly vented.

Use. No house leaders, floor drains or garage floor drains shall, directly or indirectly, be connected with the sewer, and no surface water shall be admitted to the sewer. No sewer connection shall be made or used except for the purpose of carrying off wastes from sinks, bathtubs, lavatories, set tubs and water closets.

Exceptions. Where, at the date of adoption of this section, house sewer lines existed which conformed with the requirements of applicable Village ordinances at the time of installation, in order to replace such house sewers with connections conforming with this section, the Building Inspector may permit such house sewer lines, or such portions thereof as he may determine, to remain, and only the new work need comply with the requirements of this section, provided that such method of connection meets the requirements of Sewer District No. 2 of the County of Nassau.
