ISSUE
The purpose of the project was the implementation design of the new landfill site construction of Chalkidiki’s second Management Module, for the environmentally safe waste disposal for communities:

• Vavdos, Galarino, Galatisa and Doubia of Municipality of Anthemounta
• Lakoma, Nea Gonia, Nea Silata of Municipality of Kalikratia
• Agios Mamantos, Agios Panteleimonas, Dionisios, Zografou, Nea Potidea, Portaria, Simantra, Flogita of Municipality of Moudania
• Eleochori, Krini, Nea Tenedos, Nea Triglia, Nees Plagies, Petralona, Pithari of Municipality of Triglia

The aforementioned design bade for the open contract for the selection of a contractor to build the project.

SOLUTION
The produced solid waste of communities was discharged untreated either in waste dumps, or in ravines and parcels resulting in the degradation of the natural environment.

The landfill site is located within the precinct of Galatista community of Municipality of Anthemounta and particularly in the broader region of Prinochori community, 1.1km northeast of it. The project area is located just at the southeastern edge of the hills known by the name of “Sikies”. The site consists of two cells whereas the first one occupies a total area of 4.5 hectares with a capacity of 496.000m3, and the second one occupies an area of 6.5 hectares with a capacity of 604.000m3. The design had to be sufficient for the waste disposal of the aforementioned communities for a period of 20 years. The total served population is 32.000 residents per year
