Description:
The 'AWWA Standard for Disinfecting Water Mains' (AWWA C601-68) has fallen into disuse by a number of water utilities because of repeated bacteriological failures following initial disinfection with the recommended high-dose chlorination. Other methods of disinfection, including the use of potassium permanganate and copper sulfate, do not alleviate this problem. Physical cleanliness of new mains is of primary importance and may result in successful disinfection with the low free-chlorine residuals in distribution-line water.
