Iron corrosion is one of the most complicated and costly problems facing water utilities.

Corrosion is the degradation of metal and is caused by oxidation or chemical action. If corrosion occurs in water distribution pipelines, valves and fixtures, it can cause the degradation of the quality of our drinking water.

Iron and sulfur bacteria contribute to the corrosion of iron and steel bore pipes and drinking water mains. Australian microbial guidelines seek to ensure that drinking water is free of microorganisms that can cause disease. The provision of such a supply is of paramount importance to the health of a community.

The supply of safe drinking water involves the use of multiple barriers to prevent the entry and transmission of pathogens. The effectiveness of these barriers should be monitored by a program based on operational characteristics and testing for microbial indicators.

The appearance, taste, odour, and ‘feel’ of water determine what people experience when they drink or use water and how they rate its quality; other physical characteristics can suggest whether corrosion and encrustation are likely to be significant problems in pipes or fittings.

PVC is invulnerable to underground external corrosion as well as internal pipe corrosion. This eliminates the need to specify corrosion protection methods that have become standard procedure for piping.

With PVC, long-term durability is not compromised.
