Text Box: L= ND √ p
7400

L = Allowable leakage in gallons per hour.

D = Nominal diameter of pipe, in inches.

Disinfection shall be in accordance with the following:

A. South Carolina: A disinfecting solution of chlorine or calcium hypochlorite shall be introduced at one end of the water line as water is being withdrawn at the other end so that 50 PPM of free chlorine is maintained throughout the entire water line. The chlorine solution shall remain in the piping for 24 hours, after which time the residual chlorine shall not have dropped below 25 PPM. If the chlorine residual has dropped below 10 PPM, a new disinfecting solution shall be introduced and the process repeated. The Contractor shall be responsible for installing all taps and fittings required to disinfect the line.

1) Bacteriological Analysis: Two bacteriological samples of the water shall be taken a minimum of 24 hours apart after disinfection and tested by a South Carolina DHEC approved private lab. These tests shall be conducted at the expense of the District and not the Contractor. Should the bacteriological analysis indicate that the line is not disinfected as determined by the local State or Federal regulations, the Contractor shall repeat the disinfecting process as described above at no expense to the District.

B. All chemicals, taps, testing points, and apparatus required for disinfecting the lines shall be furnished by the Contractor.

C. All water for disinfection shall be furnished by the District as specified in the pressure and leakage tests. Contractor is to provide means of transporting water from Owner's delivery point to lines to be tested.
