Abstract:
The low public acceptance is one of the major challenges in implementing and succeeding
surface water intake projects for potable purpose. The water treated from Per-Aru reservoir
is the source of water supplied by the National Water Supply and Drainage Board
(NWSDB) for some parts of Vavuniya district. The low public demand towards the use of
treated water is one of the obstacles faced by the NWSDB in operating the plant. Thus, the
objective of this study was to assess the public acceptability towards the use of Per-Aru
treated water for potable purposes in Marakarampalai area located in North-west part of
Vavuniya. This study area was selected as it purely receives treated water from Per-Aru
Water Treatment Plant for water supply. Questionnaire survey was conducted between two
groups of sample population; beneficiaries (those who have NWSDB water connection, n =
40), and non-beneficiaries (those who do not have NWSDB water connection, n = 40) in
Marakarampalai area. The questions were focused to assess the satisfaction towards the
treated water among the beneficiaries and to assess the willingness/constraints to obtain
water supply among non-beneficiaries. Results showed that half of the beneficiaries use the
treated water for potable purposes as they are aware of the periodic water quality checkups.
However, the rest only uses for non-potable purposes as they do not trust the quality of
water for potable purposes. More than half of the beneficiaries obtained the water supply
connection mainly to get rid of water shortage issues in dry season. It was noticed that the
people those who have access to alternative water sources are not willing to get water
connection paying extra bills. For non-beneficiaries, financial constraints and lack of
awareness are the major factors to get the water connection. The provision of financial
benefits and environmental education programmes by the NWSDB can be encouraged to
enhance the public demands towards the use of treated water.
