The dry powder shall first be mixed as a paste and then thinned to a one (1) percent chlorine solution by adding water to give a total quantity of seven and five-tenths (7 5/10) gallons of water per


Addendum # 1 Page 58 H

pound of dry powder. This solution shall be injected in one (1) end of the section of main to be disinfected while filling the main with water in the amounts as shown in the table which follows: Chlorine Requirements to Produce to mg/1 Concentration in 100-feet of Pipe – By Diameter

Pipe Size In Inches 100 % Chlorine, Lb. Lb. 1 % Chlorine Solution, Gals. 4 0.027 0.33 6 0.061 0.73 8 0.108 1.30 10 0.170 2.04 12 0.240 2.88

3. Point of Application

the purpose of disinfecting and as sample collection point at each branch, dead end, or a location which has a closed valve. Fire hydrants will be disinfected as part of this procedure.

b. At a point not to exceed five (5)-feet downstream from the beginning of the new main the water entering the new main will receive a dose of chlorine fed at a constant rate such that the water will have not less than 25 mg/1 free chlorine.

c. Water from the existing distribution system shall be made to flow at a constant rate into the new main.

d. The City of Rolling Meadows Water Division personnel must witness the disinfection process. An appointment with 24-hour prior notice must be scheduled with City of Rolling Meadows Water Division.

e. In the process of chlorinating newly laid pipe, all valves, fire hydrants, or other appurtenances shall be operated while the pipe line is filled with the chlorinating agent and under normal operating pressures.
