(A) Following chlorination, all treated water shall be thoroughly flushed from the newly laid pipe at its extremity until the replacement water throughout its length shows, upon test, the absence of chlorine. In the event chlorine is normally used in the source of supply, then the tests shall show a residual not in excess of that carried in the system.
(B) After flushing, water samples collected on two successive days from the treated piping system, and directed by the Village Engineer, shall show satisfactory bacteriological results. Bacteriological analysis must be performed by a laboratory approved by the Director of the Illinois Department of Public Health and the Village Engineer.
(C) Should the initial treatment result in an unsatisfactory bacterial test, the original chlorination procedure shall be repeated by the contractor until satisfactory results are obtained.
