Dissolve in water to a known concentration in a drum and pump into the pipeline at a metered

rate.

2.03 Sodium Hypochlorite (Solution)

Further dilute in water to desired concentration and pump into the pipeline at a metered rate.


AECOM REBID

2.04 Chlorine Residual Test Kit

For measuring chlorine concentration, supply and use a medium range, drop count, DPD drop

dilution method kit per AWWA C651, Appendix A.1. Maintain kits in good working order

available for immediate test of residuals at point of sampling.

PART 3 - EXECUTION

3.01 Continuous Feed Method for Pipelines

Introduce potable water into the pipeline at a constant measured rate. Feed the chlorine solution

into the same water at a measured rate. Proportion the two rates so that the chlorine concentration

in the pipeline is maintained at a minimum concentration of 50 mg/L. Check the concentration at

points downstream during the filling to ascertain that sufficient chlorine is being added.

3.02 Slug Method for Pipelines

Introduce the water in the pipeline at a constant measured rate. At the start of the test section, feed

the chlorine solution into the pipeline at a measured rate so that the chlorine concentration created

in the pipeline is 100 mg/L. Feed the chlorine for a sufficient period to develop a solid column or

"slug" of chlorinated water that will, as it passes along the line, expose all interior surfaces to a

concentration of at least 100 mg/L for at least three hours.

3.03 Disinfection of Valves, Blind Flanges, and Appurtenances

During the period that the chlorine solution or slug is in the section of pipeline, open and close

valves to obtain a chlorine residual at hydrants and other pipeline appurtenances. Swab exposed

faces of valves and blind flanges prior to bolting flanges in place with a 1% sodium hypochlorite

solution.

3.04 Disinfection of Connections to Existing Pipelines

Disinfect isolation valves, pipe, and appurtenances per AWWA C651, Section 4.7. Flush with

potable water until discolored water, mud, and debris are eliminated. Swab interior of pipe and

fittings with a 1% sodium hypochlorite solution. After disinfection, flush with potable water

again until water is free of chlorine odor.

3.05 Disinfection of Tapping Sleeves

Flush exterior of pipe with potable water after removal of existing coating. Swab exterior of pipe

with a 1% sodium hypochlorite solution. Disinfect per AWWA C651, Section 4.8. After

completion of tapping, swab interior of pipe, valves, and faces of flanges to be connected to

bypass piping with a 1% sodium hypochlorite solution.

3.06 Confirmation of Residual in Piping

A. After the chlorine solution applied by the continuous feed method has been retained in the

pipeline for 24 hours, confirm that a chlorine residual of 10 mg/L minimum exists along

the pipeline by sampling at air valves and other points of access, such as tapping valves.


AECOM REBID

B. With the slug method, confirm by sampling as the slug passes each access point and as it

leaves the pipeline that the chlorine concentration in the slug is at least 50 mg/L.

3.07 Pipeline Flushing
