Project Summary

Wastewater Management
SEWERAGE NETWORKS, PUMPING STATIONS – FORCE MAIN PIPELINES AND WASTE WATER TREATMENT PLANT FOR COMMUNITIES OF FOURKA- SKALA FOURKAS, KALANDRA-KASSANDRINO-MOLA KALIVA-POSEIDI-AIGAIOPELAGITIKA-SIVIRIS, CHALKIDIKI PREFECTURE

Client: CONSORTIUM HELLENIC CONSTRUCTION ATEVE-FILLIPOS TECHNICAL SA

ISSUE
The purpose of the project Αντλιοστάσια - Σταθμοί αναρρόφησηςwas the final design of the internal sewer networks of communities of Skala Fourlas, Mola Kaliva, Poseidi and Aigaiopelagitika. These communities belong to the Municipality of Kassandria, and they are geographically situated in the northwest coasts of the first peninsula of Prefecture of Chalkidiki. The project submitted with the design-built procedure for the selection of the contractor.

SOLUTION
The aforementioned communities were served by septic tanks. The produced wastewater was discharged untreated in the broader region resulting in the degradation of the natural environment and the quality of life for local residents.
 
The table below shows the total peak population of all communities, for each design phase.

The design of the project was pursuant to the Greek Presidential Decree 696/74. The design of the pipelines and the pumping stations was based on a 40-year horizon, while the selection of the electrical and mechanical equipment was based on a 20-year horizon. Specifically, the project included:

In each community the wastewater is collected in the corresponding pumping station – vacuum station and afterwards through an existing pipeline flows into the Waste Water Treatment Plant of Fourkas.

BENEFIT
The design of the sewer networks solved the problem of wastewater management for Communities of Skala Fourlas, Mola Kaliva, Poseidi and Aigaiopelagitika of Municipality of Kassandra.
