The drinking water supplied in the settlement is provided by the deep-drilled well located on the Kisharsány — Sáripuszta site. According to the information provided by the operator, the well water is not treated. According to the accredited water test reports submitted, the concentration of nitrate ion in the water supplied exceeds the public health limit. The aim of the intervention is to supply the village of Kisharsány — Sáripuszta with healthy drinking water instead of drinking water with nitrate content exceeding the current limit value. The essence of the technical solution is that the Kisharsány municipal core network line will be extended and connected to the Sáripuszta core network pipeline. It is necessary to restructure certain pipeline sections on the existing drinking water network of Kisharsány, however, the amount of the reconstruction of the drinking water network to be declared does not exceed 20 % of the eligible costs.
