Section 33 10 00

6. Maximum Allowable Leakage:

SxDxP0.5 L =

148,000 +0.0078 gal/hr/in of diameter for each closed valve tested against

L = Leakage in gallons per hour.

S = Length of pipe tested in feet; maximum value 2,000. When length of pipe tested exceeds 2,000 feet, the allowable leakage will be based on 2,000 feet.

D = Pipe diameter in inches.

P = Test pressure: 150 pounds per square inch.

7. Maximum Length of Pipe to be Tested: 2,000 feet, or nearest 2 valves if water on opposite side of valve is not in service.

8. Perform test against tapped cap or plug with a standpipe and not against existing valve if water on opposite side of valve is in service.

9. Repair leaks and repeat tests until acceptable results are achieved.

10. Pressure testing against existing valves not allowed.

F. Deflection Test for PVC Pipe:

1. Pull Go, No Go Gage Through Each Section:

a. Immediately after pressure testing of piping installed by directional drilling.

b. Pulled by 1 person with no mechanical advantage.

2. If Go, No Go Gage Will Not Pass:

a. Remove and replace section with new materials.

b. Undamaged pipe may be reused.

3. Vibratory rerounding device not permitted.

G. Disinfection:

1. In Accordance with AWWA C651:

a. Sodium hypochlorite.

b. Continuous-feed method.

c. Calcium hypochlorite granules not required.

d. Minimum residual 25 parts per million (ppm) initial concentration.

e. Minimum residual 10 ppm after 24 hours.

H. Flushing:

1. Water main Mainlines: In accordance with AWWA C651.

2. Water Services Into Buildings: In accordance with NFPA 24.

3. Water: Owner supplied.

4. Provide backflow preventor.

5. Velocity:

a. Water main Mainline: Minimum 3 feet per second in accordance with AWWA.

b. Water Services (Domestic and Fire Protection): Minimum 10 feet per second in accordance with

NFPA.

6. Duration:

a. Initial: Until entire volume of water in pipeline has been replaced.

b. Final: Until residual chlorine equals that of adjoining system.

7. Dispose of chlorine residual in accordance with applicable state and local requirements.

8. Disposal location to be inspected by Engineer. If there is any questions that the discharge will harm the environment, apply a reducing agent to the water to neutralize the chlorine to a 1 ppm residual.

I. Bacteriological Testing:

1. In accordance with AWWA C651 and state regulatory agency requirements.

2. Two consecutive bacteriologically safe samples must be taken at 24-hour intervals for each section of pipe tested.

3. Repeat disinfection if bacteriological test fails.

4. Collect Samples from each branch of pipe, and at a maximum spacing of 1,000 feet.

5. Engineer: Transport Samples to lab for testing.

6. Cost of initial and repeat bacteriological lab tests are the responsibility of Contractor.
