KOROPI & PAIANIA AREA WASTEWATER TREATMENT PLANT - ATTICA, GREECE
2013-2016
The WWTP Koropi – Paiania is located southeast of Athens International Airport. The plant serves the purpose of treating primary, biological and tertiary wastewater as well as sludge. It also houses various components including pumping stations, four sedimentation tanks, bioreactors, sedimentation tanks, anaerobic digesters and UV disinfection facilities. Once treated at the WWTP, the sewage is due to be discharged to surface waters through a new, 6213 m-long drain disposal pipe. This project is serving 93.000 citizens.
There are biogas engines that will be installed after the construction of the Waste Water Treatment Plant. The plant with the two units, will provide part of the heat and the electric power needed at the Koropi WWTP for sludge digestion and drying, contributing to more environmentally friendly operation of this plant.
Scope of works:
Procurement of all M&E equipment as per the design
Electrical Design for the whole plant (Cable Calculations, Lightning Protection, Lighting Design etc.)
Automation calculations and design
