AWWA JAW19881

Large doses of alum used for flocculation by the Onondaga County Water Board caused a buildup of aluminum and silicone oxides on the interior of large distribution pipes. Flow was restricted to the point that supplying demand during peak usage might have become a problem. Planning for a pigging operation was begun in 1983, and the job was successfully undertaken the following year without disrupting production of a major industrial user. The authors describe how the pigging operation was done and the improvement that resulted. Includes figure.
