Works mainly concern the construction of the sewerage main collectors of Thriassio, west of Athens and of a Wastewater Treatment Plant. 

The sewerage main collectors include four main collectors (eastern, western, northern and of Elefsina) which convey the wastewater of Thriassio area to the

Wastewater Treatment Plant. Two main pumping stations will be constructed at the Elefsina coastal area, supplying the Elefsina’s main collector. The total length of the main collectors is 36,300m. The length of open trench is 24,500m (diameter: 350mm to 700mm) and the length of micro-tunnelling is 11,800m (350mm to 900mm internal

diameter). The Wastewater Treatment Plant will be constructed at the Aspropyrgos coastal area (5.7 ha) to treat 21,000 m3/d (117,000 equivalent population) for the 1st phase of works.  The system includes a submarine pipeline (d=1,000mm, l=1.6km).
