High copper concentrations in drinking water are unsuitable for the preparation of baby food and also inhibit the use of sewage sludge as agricultural fertiliser. For both applications legislation has been changed in recent years to give better protection to the customer and environment. The copper solving potential of drinking water installations is responsible for both effects. The basis of copper corrosion is discussed as well as means to minimise output of copper from installations. As shown in several practical examples water deacidification and lime softening are measures for the water treatment process, which are easy to realise and have astonishing consequences for the copper solving potential, drastically reducing the concentration.
