This powerpoint presentation presents a corrosion control program by a water system located in Southern California in the southwest portion of Los Angeles County. The goals of this program are: reduce the corrosion rate of unlined steel and cast iron pipes; increase total chlorine residual in the distribution system; control nitrification and biofilm accumulation within distribution system pipes; increase system hydraulic capacity; and, improve water meter accuracy and performance. The system's first response to minimize these water quality problems was the implementation of a comprehensive flushing program. The results included: established representative sample locations in the distribution system and collected background data; and, collect over 10 different parameters on a daily, weekly and monthly basis. The main parameters presented here include: Total Chlorine Residual; Heterotrophic Plate Count; Customer Complaints; Time Spent Flushing; and, Water Loss Through Flushing. Includes tables, figures.
