RFP

This study was about the rehabilitation of the existing irrigation network system of Polyfytos Dam ,about 2,5 thousands hectares, in the north area of the dam's lake, the reformation of the irrigation networks, the installation of a pumping station by the lake, transferring the water to a tank nearby and a second station, pumping the water to the main irrigation tank with a volume of about 40,000 m³.
Especially for the pumping station abstracting the water from the lake, a number of alternatives were examined at a feasibility phase and included a floatable P/S, a permanent one inside the lake and a permanent one by the lake shore. The later was the proposed and accepted by the Client.

RFP

The study deals with the development of a complete remote measuring system of the external water supply network of Kalamata area and the detail description of the remote management automation system and remote control of networks, water reservoirs and pumping stations of the join water network of Messina, the surrounding communities and the city of Kalamata. It proposed the installation of flow and pressure measuring stations at all junctions and with wireless system data transmission to the control center of the wastewater treatment plant. It also involved proposals for the system's extension of the distribution network with the installation of a fixed leakage control system
It also included the study of the Sanitation Network that consisted of the detail description of the remote management automation system for the sewerage network, the pumping stations, the main collector pipe and the Waste Water Treatment Plant. In the sewerage network, three (3) local control stations, TSEA type, were installed for the monitoring of the daily consumption of pumping stations A5, A6 and A10. With the whole remote system installed, the sanitation network was satisfactorily observed.

RFP

The objective of the study was the detailed design for the construction of the water supply and irrigation dam “Manikia” in Evia Perfecture, central Greece. Manikia dam was designed as an earthfill dam with a clay core and its basic technical characteristics are:
- River Basin upstream of the dam: 13.60 km².
- Elevation at the dam's axis: +729 m in the river valley, +774 m at dam's crest, +770 at dam's f.s.l.
- Total capacity of the dam: 2,602,000 m³, usefull capacity of the dam: 2,399,500 m³.
- Dam's height (at the axis): 54 m.
- Irrigation area (downstream): 800 ha, water supply demand 3.43 hm³/year for Kymi and Aliveri cities.
Construction of dam was ended at 2003. Now it is in full operational mode.
