Preliminary Design

Stormwater and sewage network study of the Communities of Ekali, Drosia, Stamata, Rodopoli, Anixi, Ag.Stefanos, Dionisos and Krioneri

The project areas belong to the Municipality of Ag.Stefanos and the Communities of Ekali, Drosia, Stamata, Rodopoli, Anixi, Dionisos and Krioneri. The study areas are situated in the upstream part of the northern suburbs of the Attica basin and they have 12 basic streams, 7 of which fall into Kifissos river and the other 5 in the lake of Marathonas (Haradros river basin).
Major design problems were erosion and high sediment yield. The project design takes into account the environmental protection restrictions of the surrounding area.

Design of water infrastructure for a major port facility

The wastewater collection works include the main sewers pipeline, pumping station and twin pressure mains.
The wastewater treatment plant includes the full extent of necessary substructures designed to provide for the 3-stage treatment of an 18.000 equivalent population of industrial wastes. The project  included the full spectrum of civil and mechanical engineering design.
The final discharge pipes include the collector pipe transporting the effluent from the WWT plant to the sea, incuding an underwater pipeline and all the auxilliary structures.
