The project concerns the supply, installation and operation of a water treatment system in order to remove iron from the drilling “Skofas”, the Local Community of Vavdos of the Municipality of Polygyros, Halkidiki, in which iron was detected above the legal limits, in accordance with the Joint Ministerial Decision (CYA) Y2/2600/2001 F.E.K 892/11-7-2001 on the quality of drinking water, in compliance with Directive 98/83/EC. The water pumped from the drilling, via an underwater pump assembly with a capacity of 3030 m²/hour, shall be transported through a depressing pipeline to the collection-balancing tank and from there to the chelation filter. After the chelation filter will end up in the clean water tank and from there with an underwater pumping complex booster, in the existing water supply tank of the settlement. The system will be single and automatic. All functions will be controlled by a central control panel. The implementation of the project achieves the improvement of the quality of drinking water, promoting public health.
