The communities (villagers) here are dependent on underground water supplies, the supply system is in the form of artesian wells, many of them have dried up, the reason is climate warming, but those that are still functional are outdated and either were made with unsuitable material or corrosion has occurred, because of these problems there are components in the water that are dangerous and affect the human health. It is therefore important to ensure a clean water supply free of undesirable substances to ensure better health of the population and prevent various diseases and dehydration. We are currently preparing assistance in the form of filtration equipment to the village of Grepan. Thanks to financial support from the Official Development Assistance Programme of Slovakia, SlovakAid.
