F. 
Air release vaults shall consist of forty-eight-inch concrete pipe with a Neenah R-1758 Series, or equal, with frostproof lid.
The manufacturer shall inspect all pipe and fittings and shall furnish three certified copies of tests and inspection reports covering description, hydrostatic test, physical properties, chemical analysis and coating analysis.
A. 
All pipe furnished under this specification may, after delivery and before use, be subject to inspection by the Township. Material which does not meet all requirements of this specification will be rejected.
B. 
The Township shall be notified when the pipes are to be laid in the trench, and none shall be covered until they have been inspected by the Township. At least 25 feet of pipe shall, under ordinary circumstances, be laid before covering begins.
A. 
Proper implements, tools and facilities shall be provided and used for the safe and convenient prosecution of the work. All pipe, fittings, valves and specials shall be carefully lowered into the trench in such a manner as to prevent damage to the protective coating and linings. As a minimum, a Class C trench bedding with granular fill material embedment shall be used for force main installation.
B. 
Pipe and fittings shall be carefully examined for defects, and no pieces shall be laid which are known to be defective. Before lowering and while suspended, cast-iron pipe may be gently tapped with a hammer to check for cracks. Defective, damaged or unsound pipe shall be rejected. If any defective piece shall be discovered after having been laid, it shall be removed and replaced with a sound one, at the contractor's expense. All pipes and fittings shall be thoroughly cleaned before they are laid and shall be kept clean until accepted in the completed work. Pipe which has been contaminated with mud or soil shall be cleansed with a swab.
C. 
The pipe shall be supported its full length by the uniform grade of the trench, and a bell hole shall be dug at each joint, said hole being of sufficient size to ensure proper making up of each joint. Pipe ends shall not be left open at the end of a workday or during temporary suspension of construction, but shall be securely covered to prevent the entry of foreign matter or small animals. Kinks or sharp bends giving excessive deflection or which put pipe joints in strain will not be permitted. The maximum permissible deflection per joint shall be in accordance with manufacturer's recommendations.
D. 
When cutting short lengths of pipe, a pipe cutter shall be used and care shall be taken to make the cut at right angles to the center line of the pipe. In the case of push-on pipe, the cut ends shall be tapered with a portable grinder, or cement pipe shall be cut by means of pipe cutters of the blade type or with abrasive wheels. The pipe shall then be filed, beveled or machined, as required.
E. 
Thrust blocks shall be Class C concrete. Thrust blocking pads, clamps, and rod assemblies shall be provided at fittings, valves or special equipment. Clamps, rods, straps, nuts and bolts shall be coated with coal tar enamel after assembly and installation.
F. 
Pipe joints.
(1) 
Push-on-type joints. Push-on type joints such as Bell tight, Tyton or equal joints shall be prepared by removing all dirt or foreign material from the bell end of pipe and inserting the gasket. The spigot end of the pipe shall be prepared by cleaning and applying a thin coat of approved lubricant after which the spigot end is centered in the bell and jacked on by using a special jack and choker sling. The procedure in making up this joint shall be performed in accordance with the recommendations of the manufacturer.
(2) 
Mechanical joints. When making up mechanical joints, the spigot end of each pipe shall be entered into the adjoining bell to within 1/8 of the total depth of the bell. The pipe shall be properly centered and have uniform space around for reception of the packing material. The packing material, bolts, nuts and other accessories used in making mechanical or sleeve-type joints shall be obtained from the manufacturer of the pipe and joints. The surface of the spigot and bell shall be brushed thoroughly with a wire brush just prior to slipping the gasket on and entering into the bell.
(3) 
Coupled joints. Coupled joints, such as used in joining asbestos cement pipe, shall be constructed in accordance with the recommendations of the manufacturer.
(4) 
Plastic pipe joints. Joints in plastic pipe formed of polyvinyl chloride shall be push-on-type or such other type joint approved by the Engineer.
(5) 
Restrained joint. A restrained joint shall be any type of locked joint manufactured by Clow Corporation, American Cast Iron Pipe Company, Griffen Pipe Company, or equal. The restrained joint shall mechanically prevent the pipe from pulling apart under tensile stresses.
G. 
Where the use of nuts, bolts, washers, rods, straps and clamps are required due to the peculiarities of the installation, these items shall be installed and be of the proper size and dimension. After installation and before backfilling, all the above items shall be painted with bituminous paint or coal tar enamel.
Gate valves shall be AWWA, iron body, bronze-mounted, double-disc, parallel-seal-type, designed to take full pressure on either face. All gate valves shall be by the same manufacturer, with nonrising stems with operation nut, and shall be Clow, Mueller, M & H, or accepted equal.
A. 
Whenever any section of force main has been completed and is ready to be tested, the contractor shall flush the force main to remove all sand, dirt, debris, etc. Flushing shall be done under the observation of the Township Inspector and at a time approved by the same.
B. 
After installation, all force mains shall be tested in sections where and as directed by the Township Inspector. The sections shall be plugged at both ends and connected to a calibrated water supply. The contractor shall slowly fill the force main with water in preparation for the hydrostatic pressure test, ensuring that all air is expelled from the pipe. The contractor shall make the necessary taps at points of highest elevation in order that the air may be expelled. The main shall be subjected to a hydrostatic test pressure of 150 psi for a period of not less than 30 minutes. Pressure shall be applied to the main by means of a hand pump for small lines or by use of a gasoline pump for larger lines. During the duration of the test, the lines shall be thoroughly examined for leakage and elimination of leakage effected where necessary. Make-up water shall be measured with a displacement meter.
C. 
Leakage shall not exceed 25 gallons per day per inch of diameter per mile. Any cracked or defective pipes, fittings or valves discovered in consequence of the pressure test shall be removed and replaced by the contractor at his own expense. After replacing or correcting cracked or defective pipe fittings or valves discovered in the test or correcting any leakage, the contractor shall retest the pipe. In the event that the pipeline is tested in sections and temporary thrust blocking is required, a temporary plug or cap shall be installed and blocked with a screw jack firmly braced against the end of the trench or against a heavy timber embedded into the side of the trench.
Cleanouts shall be installed on all force mains at intervals not to exceed 1,000 feet. The location of each cleanout will be accurately recorded and indicated on the record drawing. The location shall be referenced to at least two permanent markers. The tees will be buried and covered with the normal backfill.
The contractor shall furnish and install a detectable identifying tape in all trenches where nonmetallic pipe is used. The identifying tape shall be made of polyethylene tape bonded to a metalized foil and shall be highly resistant to alkaloids, acids or other destructive chemical components likely to be encountered in soils. The tape shall be three inches wide, shall be brightly colored to contrast with soil and bear an imprint identifying the type of line buried below. The tape shall be placed approximately 18 inches below the finished grade.
