The Contra Costa Water District (California) needed to increase the total chlorine residual in the eastern part of its system. The district's nonsheen monitoring program detected regrowth problems that would not have been evident from coliform- and heterotrophic plate count monitoring alone. The most effective means of controlling the regrowth problem is to install a chloramine booster pump. Bench-scale tests indicated ammonia addition at the booster station will not be necessary. Eliminating the need for ammonia storage and feed systems, the total installation reduced the cost by 25 percent.
