Practical evaluation of iron corrosion control in a drinking water distribution system

This study describes the influence of different corrosion control programs on corrosion rates, and the short-term effects of various levels of corrosi veness on bacterial water duality in model drinking water distribution syst ems. Corrosion rates were strongly related to seasons and water temperature . This suggests that slightly higher corrosion inhibitor concentrations wou ld be required during summer and possibly lower dosages during winter month s. Over a one-year period, bacterial water quality data were similar in new pipes receiving waters with different corrosiveness and phosphate levels, suggesting that corrosion affects bacterial water quality over longer perio ds of time.
