The symptoms we notice in the water supply sector are treated by one authority,
responsible for only one part of the sector. The research ... Extra attention is paid
to the presence of organic matter, both natural organic matter (NOM) and also
trace organics. ... Beneficial measures taken at the treatment plant for organic
matter removal might also be appropriate for the maintenance and operation of
the distribution network, including the prevention of water quality deterioriation. 5.

During water distribution, disinfection process is essential to prevent waterborne
diseases and ensure water quality from the water treatment plant outlet to the
consumer's tap. ... There is no doubt that chlorine is an effective disinfectant
against most microorganisms and it provides protection in the distribution
network. ... 2011). The removal of DBPs precursors such as natural organic
matter (NOM) from water represents one of the effective strategies for controlling
the formation of DBPs.
