SECTION 02 51 90

DISINFECTION OF WATER LINES

PART 1 GENERAL

4 .1 DESCRIPTION

A. The work of this section consists of the disinfection of all portions of the water system, including valves and stops and any portion of the existing connecting system that might have become contaminated during construction activities.

PART 2 PRODUCTS

5 .1 CALCIUM HYPOCHLORITE

A. Calcium Hypochlorite product having approximately 70 percent available chlorine.

5 .2 MIXTURE

A. A 5-percent solution shall be made by mixing 5 percent of powder with 95 percent water, by weight, first into a paste, then thinning to slurry by the addition of water.

PART 3 EXECUTION

6 .1 DOSAGE

A. Place enough disinfecting material in the system to ensure a chlorine dosage of 50 parts per million. This is equivalent to 10 ounces of commercial hypochlorite powder to each 1,000 gallons of water.

6 .2 FILLING SYSTEM

A. Fill entire system with the chlorine solution. Open all taps and valves and leave open until a strong odor of chlorine is noticeable in the water coming from the outlets, after which close the taps and valves.

6 .3 TEST PERIOD

A. Allow chlorinated water to remain in the system a minimum of 24 hours, then thoroughly flush the system. During retention period, operate all valves, stops, and other appurtenances to assist this disinfection.

6 .4 DISPOSAL OF CHLORINATED WATER

A. Dispose of chlorinated water as approved by the Contracting Officer’s Representative. Include chlorinated water disposal method in the submittal approval process.

6 .5 BACTERIOLOGICAL EXAMINATION

A. After the system has been thoroughly flushed, take samples from representative points in the system, in sterile bottles, and submit to proper authorities as directed for bacteriological examination. If the report is unsatisfactory, repeat the disinfection procedure until satisfactory results are obtained.

10 .4 INSTALLATION

A. Inspection: Inspect pipe for defects before lowering into trench. Defective, damaged, or unsound pipe will be rejected.

B. Laying: N/A

C. Cleaning: As work progresses, clear the pipe interior of dirt and other debris by keeping swabs in the pipe and pulling them forward past each completed joint.

D. Pipe Cutting: Cutting for closure or other reasons shall be done neatly by methods recommended by the manufacturer. Sharp edges shall be smoothed to prevent gasket damage.

E. Jointing: Clean gaskets and seats of foreign materials prior to joint assembly. Apply lubricant as recommended by the pipe manufacturer.

1. Push-On Joint: Carefully insert the spigot end into the bell to prevent entry of dirt and incorrect entry angle. With suitable fork tool, crowbar, or by hand, make the joint to the insertion depth recommended by the manufacturer. When the selected pipe uses joints not designed for full depth insertion, prevent further closure of previously completed joints by restraining movement of the installed line while making succeeding joints.

2. Mechanical Joint: Carefully center the spigot in the bell and position the gasket evenly in the seat. Tighten bolts alternately to an even torque, causing the follower gland to expand the gasket uniformly for a tight seal.

3. Plain End Jointing: Install factory made couplers in accordance with manufacturer's directions. Center the coupling collar over the joint and tighten bolts evenly.

4. Flanged End Jointing: Install correct gasket for flange faces used, and tighten bolts evenly.
