Abstract

Providing safe water supply is one of the important public health priorities, the water quality of
water supply is closely associated with human health. The aim of this study was to assess the quality of water in
the urban water supply systems and their authority organizations including the existing performance of the water
supply systems and their organizations. The sampling locations were covered by 4 cities, namely Nakhon
Ratchasima (Korat), Chaiyaphum, Buriram and Surin provinces. There was the total of 13 sampling site
locations of the urban water supply systems which are owned by the provincial and municipal waterworks
authorities. Water samples of each sampling site location were collected from water resources, storage tanks, and
household water taps, and analyzed for various parameters. The results showed that the water quality of the
urban water supply systems had met the water quality standards for the parameters: turbidity, TSS, TDS, Nitrate,
and total coliform, except color and iron due to the retention time of the sedimentation process which was not the
proper range. Besides, there were problems with the residual chlorine in storage tanks and household tap water
which was lower than the standard limit and might affect population health. There was no difference between the
performance of the provincial and municipal waterworks authorities. The outcome of this study can support the
improvement of the urban water supply systems and their authority organizations.
