Review of potable water biofilms in engineered systems
Microbial biofilm formation on pipe walls has been shown to cause serious problems in potable water systems, including corrosion and the provision of sites for pathogenic bacterial development. Thus control of the biofilm becomes one of the main objectives of good drinking water distribution practice. However, control of bacterial growth of pipe surfaces is difficult, as conventional chlorination procedures do not prevent accumulation of biofilms. Therefore, other preventive measures may have to be used. The review will also address the microbiology of potable water biofilms, factors governing the accumulation of biofilms in potable water, and measures (both short and long term) for the control of biofilms in potable water. The potential health threat associated with biofilms in potable water systems is discussed. An emerging problem is developing within the water sector with respect to the virulence of opportunistic bacterial pathogens which are, as well as being part of the normal planctonic heterotrophic bacterial population, readily isolated as sessile populations removed from pipes transporting potable water. Essentially only the bacteria in biobilms of potable water systems are multiplying and, owing to sloughing as a result of water shear, these constitute one of the main causes of deterioration of the microbiological quality of potable water systems, which could constitute a public health issue.
