A highly significant groundwater reserve zone has been identified in Nea Zichni, Serres, by the Hellenic Survey of Geology and Mineral Exploration (H.S.G.M.E.), following the successful completion of a water supply borehole drilled by the Municipality of Nea Zichni, Serres.
The borehole location was determined after a specialized hydrogeological study conducted by Ms. Maria Lazaridou, hydrogeologist from the Regional Unit of Central Macedonia. The project was monitored and implemented in a coordinated manner by H.S.G.M.E., following a request from the Municipality of Nea Zichni to address the water supply issue of the Municipal Community of Alistrati.
It is worth noting that this specific borehole not only provides a permanent solution to the pressing water supply problem of Alistrati but also has the potential to meet future water supply needs of the wider area of the Municipality of Nea Zichni, Serres.
The borehole was positioned on a schist formation, with the aim of penetrating this layer and reaching the underlying marble formations. The drilling depth reached 234 meters. During drilling, a well-developed karstic aquifer was detected within the marble formation.
A pumping test was conducted, achieving a discharge rate of 60 m³/h (limited by the pumping system capacity), while the observed water level drawdown during pumping was only a few centimeters — indicating a particularly strong and sustainable aquifer.
