New york city diameter

The size and length of the tunnel, its sophisticated control system, the placement of its valves in special chambers and the depth of excavation, represent state-of-the-art technology. While city tunnel no. It will also allow the DEP to shut down, inspect and repair city tunnels nos. Similar to city tunnels nos. About 13 miles long and constructed in bedrock to feet below the surface, stage one extends south through the Bronx, into Manhattan and across Central Park.

Stage one is a foot diameter concrete-lined pressure tunnel, which steps down in diameter to 20 feet. As water travels along this route, it rises from the tunnel, via 14 supply shafts and feed into the distribution system. Stage one started its operations in July and has been providing water to some residents in Queens, Manhattan and Bronx. Three of the four unique subsurface valve chambers were built to allow the connection of future stages of the tunnel without removing the water or taking any other stage of the tunnel out of service.

Each valve chamber contains a series of inch diameter conduits with valves and flowmeters to direct, control and measure the flow of water in sections of the tunnel. More importantly, stages one and two will provide bypass capability of city tunnels no. Stages one and two are solely devoted to improving the distribution capability of the system and will not provide any additional supply of water. The tunnelling of stage two was completed in Stage two is being constructed in two separate sections.

The Brooklyn leg of the tunnel is feet in diameter and the Queens leg is feet in diameter. The eight-and-a-half mile long Manhattan section is ten feet in diameter.

It begins at the stage one valve chamber in Central Park and runs south along the west side of Manhattan, east to the vicinity of South Street Seaport and north along the east side of Manhattan to 34th Street. Tunnel boring and installation of concrete line and ten shafts along the tunnel was completed in May It can manage the flow of about million gallons of water per day by the borough.

From the Valve Chamber, water can be delivered to city tunnel no. When stage three is completed, city tunnel no. It will also provide an additional aqueduct to supply water to the city, which will run parallel to the Delaware and Catskill Aqueducts. This final stage will be miles long and will extend southeast through the Bronx from the Van Cortlandt Park Valve Chamber. It will then travel under the East River into the Flushing area of Queens. In a design departure from the two existing tunnels, valves which control the flow of water in tunnel no.

The valves for city tunnels no. When city tunnel no. Bookmarks: Save and quickly access sections most relevant to your project. Code compare: See differences between code years or jurisdictions. Amendment styling: Highlight changes enacted by your local jurisdiction.

The trap shall be placed as close as possible to the fixture outlet. The vertical distance from the fixture outlet to the trap weir shall not exceed 24 inches mm and the horizontal distance shall not exceed 30 inches mm measured from the centerline of the fixture outlet to the centerline of the inlet of the trap.

The height of a clothes washer standpipe above a trap shall conform to Section A fixture shall not be double trapped. Exceptions: This section shall not apply to fixtures with integral traps. A combination plumbing fixture is permitted to be installed on one trap provided that one compartment is not more than 6 inches mm deeper than the other compartment and the waste outlets are not more than 30 inches mm apart. A grease interceptor intended to serve as a fixture trap in accordance with the manufacturer's installation instructions shall be permitted to serve as the trap for a single fixture or a combination sink of not more than three compartments where the vertical distance from the fixture outlet to the inlet of the interceptor does not exceed 30 inches mm , and the developed length of the waste pipe from the most upstream fixture outlet to the inlet of the interceptor does not exceed 60 inches mm.

This section shall not apply to outdoor drinking fountains discharging to a drywell. Fixture traps shall be self-scouring. Fixture traps shall not have interior partitions, except where such traps are integral with the fixture or where such traps are constructed of an approved material that is resistant to corrosion and degradation. Slip joints shall be made with an approved elastomeric gasket and shall be installed only on the trap inlet, trap outlet and within the trap seal.

The following types of traps are prohibited: Traps that depend on moving parts to maintain the seal. Bell, pot, bottle traps and traps with interior partitions. Crown-vented traps. Traps not integral with a fixture and that depend on interior partitions for the seal, except those traps constructed of an approved material that is resistant to corrosion and degradation.
