6. When work is not in progress, securely close open ends of pipe and fittings.

7. When high density polyethylene or solvent weld joint pipe is used, it shall be weaved in the trench to provide horizontal slack in the line for expansion and contraction.

8. High density polyethylene pipe shall be allowed to cool to within 20ºF of the shaded trench bottom temperature before backfilling.

9. When pipes are installed in a structure or utility box, they shall be adequately supported.

10. Use proper fittings in order to follow the required line and grades and to avoid excessive curvature. Deflections from a straight line or grade, as required by vertical curves, horizontal curves, or offsets, shall not exceed the manufacturer's recommended maximum joint deflection or curvature for their pipe.

11. When more than one pipeline is in the same trench, the pipes shall be separated by at least eight horizontal inches, or as shown on the Drawings.

12. Bends that result in joint tension or permanent pipe deformation are prohibited.

Butt fusion joining between same diameters but unlike wall thickness shall not be permitted. Transitions between unlike wall thickness shall be made with a transition nipple (a short length of the heavier wall pipe with one end machined to the lighter wall) or by mechanical means.

e. Branch connections to the main shall be made with polyethylene fittings, and butt fused.

f. Bent Strap Test: On each day that butt fusions are to be made, perform a “Bent Strap Test.” The first fusion of the day shall be a trial fusion.

New waterlines that are extensions or modifications of an existing water system shall be tested at the test pressure specified here unless the Contracting Officer specifies another pressure. Pneumatic testing will not be allowed.

2. The contractor shall ensure that any appurtenance attached to the pipeline at the time of testing is rated to withstand the pressures that will exist during testing.

3. Conduct piping tests before joints are covered and after thrust blocks, if required, have hardened sufficiently. Joints shall remain uncovered until testing is completed satisfactorily.

4. The Contractor shall furnish the pump, pipe, gauge, measuring device, connections, and all other necessary equipment, and shall furnish the necessary personnel to conduct the tests. All equipment, gauges, and attachments shall be subject to approval by the Contracting Officer.

5. The Contracting Officer shall be present during the testing period.

6. Waterlines shall be tested in sections not to exceed 2,000 ft in length or a maximum pressure differential of 30 psi in the test section.

7. No paints, asphalts, tars, enamels, or other types of pipe compounds shall be used to eliminate leaks.

B. Pressure and Leakage Test

1. The test pressure shall:

a. Equal at least 125% of the normal working pressure at the highest elevation of the test but not exceed 160 psi at any point being tested.

b. Not exceed the thrust restraint design pressures.

c. Not vary by more than +/- 5 psi from the established test pressure.

d. Not exceed twice the rated pressure of valves when the test section includes closed valves.

e. Be not less than 100 psi for all piping within buildings.

2. Pressure Test Procedure

a. Equipment: The test pressure shall be applied by means of a pump connected to the pipe in a manner satisfactory to the Contracting Officer.

WATER DISTRIBUTION SYSTEMS 221100- 11

b. Preparation: Fill pipeline 24 hours before testing. Use only potable water.

Each valved section of pipeline shall be slowly filled with water and all air shall be expelled from the pipeline. Apply test pressure to stabilize system.

c. Pressurization:

1) Increase pressure in 50-psig increments and inspect each joint between increments.

2) Hold at test pressure for 1 hour.

3) Decrease to 0 psig.

4) Slowly increase again to test pressure and hold for 1 more hour. If the test pressure cannot be sustained within +/- 5 psi during this time, then the system will be determined to have leakage.

5) Leakage shall be verified by the Contractor and the Contracting Officer.

6) Locate and repair leaking joints with new materials and repeat test until leakage is within allowed limits. All visible leaks are to be repaired regardless of the amount of leakage.

d. Examination: All exposed pipe, fittings, valves, and joints shall be carefully examined. Any cracked or defective pipe, fitting, or valve discovered shall be repaired or replaced by the Contractor at his own expense with new material and the test repeated until satisfactory to the Contracting Officer.

3. Results

a. The Contractor shall furnish a written report to the Contracting Officer describing the results of each test. The report must identify the specific portions of the pipeline tested, the pressure, the duration of the tests, and the amount of leakage.

3.8 CLEANING AND DISINFECTION

A. Clean and disinfect water-distribution piping as follows:

1. Purge new water-distribution piping systems and parts of existing systems that have been altered, extended, or repaired before use.

2. Use purging and disinfecting procedure prescribed by authorities having jurisdiction or, if method is not prescribed by authorities having jurisdiction, use procedure described in AWWA C651 or as described below:

a. Flushing Pipelines

1) After the pressure and leakage testing has been completed, all water pipes shall be thoroughly flushed.

2) Flushing shall remove all debris from the pipeline, including HDPE pipe shavings, gravel and any other material that may have accidentally entered the pipeline during construction.

3) Remove all self-closing faucets from hydrants before flushing lines.

Failure to do so will likely clog the internal parts of the faucet.

WATER DISTRIBUTION SYSTEMS 221100- 12

4) Minimum velocities must be obtained in all mainlines, laterals and drainlines.

5) Ensure flushing outlets have adequate drainage and no damage or erosion will occur from the flushing process. Install hoses and/or pipe extensions if necessary.

1) Pipelines: After flushing, all new waterlines and repaired portions of, or extensions to, existing waterlines shall be disinfected by chlorination. Chlorination shall provide a minimum of 25 mg/l residual after 24 hours contact in the system. This may be expected with an application of 50 mg/l, although some conditions may require more.

The entire system including the storage tank or spring box shall be filled with the disinfecting solution. All taps, hydrants, and other outlets shall be opened and left open until chlorine is noticeable by odor or testing in the water coming from each. Immediately close taps, hydrants, and other outlets.
