9-2-4: METHOD OF CONSTRUCTION:

1. All joints shall be yarned with the manufacturer's recommended pounds of square braided jute which shall be driven in, with proper tools, to provide for a uniform depth of lead around the circumference of the pipe. Joints shall then be filled with hot lead, care being taken to make certain that the lead is hot enough so that it will not chill as it enters the bell. A joint runner of proper size should be used to prevent the jointing material from running out. Each joint shall be filled with the manufacturers recommended pounds of lead. The joints shall then be caulked by experienced workers and with tools of proper size. In no case will large caulking tools, which might become wedged between the bell and spigot of the pipe, be allowed. All fittings and valves shall be jointed to the pipe in the same manner as described above for pipe joints. (Ord. 14.04)
2. If mechanical joint pipe is used, rather than bell spigot, it shall be laid as described above for bell and spigot pipe. Care shall be taken to make certain that the spigot is centrally located in the bell so that a secure and tight joint may be obtained. The bolts shall be tightened progressively so that the gland is brought up toward the pipe flange evenly and so that the same distance is maintained between the gland and the face of the flange at all points around the socket. Each joint shall be provided with a copper wire bond from one pipe to the proceeding pipe so that it will be possible to have a complete electrical circuit for the entire length of the line. The copper wire may be spot welded to each pipe or connected through the joint all in a manner satisfactory to the engineer, inspector and/or city superintendent. Upon completion of the line and after hydrostatic pressure tests have been completed, each joint shall be wrapped with burlap and hot asphalt.
3. The joint, when finished, shall be completely covered and protected from any action from the surrounding ground.

D. Types Of Pipes And Joints: These specifications cover types of pipe and joints now being manufactured and in common use. It is possible that, in the future, new types of joints will be manufactured. These joints may be used only if prior approval has been obtained from the engineer representing the city or the city superintendent.

E. Concrete Blocks: Concrete blocks shall be poured between the undisturbed part of the trench and the fittings in cases where the water line changes direction, such as at tees, bends and elbows. Wherever a line dead ends, a concrete block shall be poured between the end of the line and the undisturbed part of the trench. Concrete blocks shall be poured between the undisturbed part of the trench and the fire hydrants. These concrete blocks shall be of sufficient size to hold the line firmly in place when excessive pressures, due from water hammer, are placed on the line.

F. Backfilling Between Joints: As soon as the line has been laid and inspected by the inspector, the engineer, or the city superintendent, the line may be backfilled between the joints. Backfilling shall be done with the excavated material (when same is suitable) and shall be placed in thin layers, each layer being thoroughly compacted before the next layer is placed. Backfilling shall be to a depth of at least eighteen inches (18") over the top of the pipe.

G. Pressure Test: After the line has been backfilled and compacted between each joint, the line shall be subjected to a hydrostatic pressure test of fifty percent (50%) above the maximum working pressure of the line. The duration of each pressure test shall be at least thirty (30) minutes. Each valved section of the line shall be slowly filled with water and the specified test pressure, measured at the point of lowest elevation, shall be applied by means of a pump connected to the pipe in a satisfactory manner. Before applying the test, all air shall be expelled from the line. To accomplish this, taps shall be made, if necessary, at the points of highest elevations and afterwards tightly plugged. All joints shall be carefully examined during the pressure test and any joint found to be leaking shall be caulked or tightened until the leak is stopped. All pipe, fittings or valves found under test to be defective shall be removed and replaced and the test again applied. This procedure shall be continued until the line is approved by the inspector or the engineer representing the city, or the city superintendent.

H. Layers Of Backfill: After tests have been completed, the remainder of the line shall be backfilled. Backfill shall be in layers, each layer being thoroughly tamped with a tamper weighing not less than twenty (20) pounds and having a surface of not more than eight inches (8") in diameter. Rocks larger in volume than six inches (6") cubed shall be excluded in the backfill around the pipe and for a distance of two feet (2') over the pipe.

I. Surfacing Improved Or Graveled Streets: On improved streets or alleys, such as streets and alleys having concrete, cement asphalt or road mix oil surfaces or on graveled streets where the amount of traffic requires that the street be repaired and left in as good a condition as before the work commenced, the backfill shall be tamped for the entire depth of the trench and until at least ninety percent (90%) of the original density has been acquired. After the trench has been thoroughly compacted and approved by the engineer or city superintendent, a surface, conforming to the type of surface in place on the undisturbed part of the streets or alleys, shall be replaced over the trench excavation and the streets or alleys shall be left in as good a condition as before the work commenced.

J. Tamping Unimproved Streets: On unimproved streets or alleys, when a covering of two feet (2') has been placed on top of the pipe, as above described, tamping may be dispensed with and water used for settling the backfill as directed by the engineer, inspector or city superintendent and the streets or alleys left in as good a condition as before the work commenced.

K. Gate Valves: On any water line installed in the city, sufficient gate valves shall be installed so that the services in each block may be discontinued without disrupting the service in the adjacent blocks. Gate valves shall be installed ahead of each hydrant. Each valve shall be provided with a valve box of the type described in subsection 9-2-3C3 of this chapter. (Ord. 14.04; amd. Ord. 2.32)

The pipe shall then be laid by means of a grade rod, grading each pipe as it is laid from the invert of the pipe to the grade string. All pipe shall be laid with the bells upgrade. Pipe shall be laid continuous from beginning to end. No break in the line shall occur at points where manholes are to be installed. The grades on which the sewer is laid shall conform exactly to the grades shown on the plan and profile submitted to and approved by the city council. If it is found desirable during construction to revise the grade, such revision shall be first submitted to the engineer or city superintendent for approval. Any such changes shall be noted on the "as constructed drawings".
2. As soon as the pipe has been laid and properly graded, a length of dry unoiled jute shall be caulked into the annular space of the bell of the pipe. The jute shall be of sufficient diameter and thickness to hold the spigot end of the pipe concentric with the bell of the proceeding pipe and shall be of sufficient length to encircle the barrel of the pipe.
3. When finally caulked, the jute shall take up approximately twenty five percent (25%) of the depth of the socket or bell and shall be filled with jointing compound.
4. The jointing compound shall be poured into the socket or bell with the use of asbestos or rubber joint runners of suitable diameter and length to seal the outer joint face while pouring the joint. The jointing compound shall be heated to the temperature recommended by the manufacturer before pouring. The compound shall be poured into the joint using a container of sufficient size so that the joint can be filled in one pouring. The joint runner shall be left in place until the joint has cooled to the extent that the jointing compound will not sag or creep when the runner is removed. In cases where adhesion cannot be obtained between the compound and the pipe, the interior of the bells and the spigot ends of the pipe shall be painted with a joint primer. This primer shall be applied twenty four (24) hours prior to the time the pipe is to be laid so that the primer is dry and hard. Wherever it is necessary to pour joints in the presence of water, the trenches shall be kept water free during jointing and for a sufficient period thereafter to allow the jointing material to become fully set and completely resistant to water penetration.
5. Eight inch by six inch (8" x 6") or eight inch by four inch (8" x 4") wye junctions shall be provided for each lot that the sewer is to serve. The si
