Corrosion control actions for drinking water distribution in Sweden are discussed. Several different processes are used. The water quality goals vary over a wide range both with respect to pH and alkalinity. None of the waters are supersaturated with respect to calcium carbonate. The results of the corrosion control action on copper and iron corrosion product release are calculated and discussed in terms of possibilities for improvements. The effect of water quality changes due to pipe material succession order is shown.
