Civil and structural engineering design for Athiainou Sewage Treatment Plant (STP), Long Term Storage, Emergency Storage and Sludge Treatment and Storage, Irrigation pumping station, pumping Stations within Athiainou collection system and associated works for the supply of power to the pumping stations, Access Road to the STP and installation of the necessary utilities and infrastructure laid in the access road for the operation of the works.

Designed the long term storage lagoon that has a capacity of 100.000m³ and emergency storage lagoon 2.300m³.  The embankments were checked for slope stability under static and dynamic conditions for wet and dry situations using GEO 5 geotechnical suite.  The seismic parameters used for the water retaining structures and the crack control design were calculated based onEN1992 and EN-1998 using an internally developed software.
