The municipality of Hantos has a separate water supply system, but the water quality does not meet the water quality requirements of Government Decree No 201/2011. It is therefore appropriate to take into account own water resources. Water supply from surrounding water bases is uneconomic, so local water supply is recommended. The project is carried out in the municipality of Hantos. The planned reconstruction does not exceed 20 % of the total eligible costs. On 15 November 2013, OKI issued an opinion under file No 6413/2013 that due to the arsenic content, participation in projects improving drinking water quality is eligible.
