Consultant for assisting DEYAMV in the assesment of current water supply situation in N. Ionia area, water network zoning and calculations, water network separation in water losses control zones (District Metered Areas – DMAs). Control stations and relevant equipment determination. General plans and basic design plans of proposed works. Assistance in Project Data documentation (scope determination, losses estimation report etc).
- Three (3) interchanges : (α) Ag. Marinas - Stylidas(β) Stylidas - Karavomilou (γ) Karavomilou - Ahinou.
- Temporary works during construction period.
It is a rockfill dam with clay core, 77m high and 560m crest length. The total volume of the dam is 2.700.000m3. The dam is founded on gneiss. Dam reservoir's capacity is 12.000.000m3.
The spillway has discharge flow of 370m3/s (PMF), with maximum width 32m. The energy dissipation is achieved through a flip bucket and a steeling basin.
The cross-section of the diversion tunnel is of horseshoe shape with 150m radius. When the construction is over, it is converted to an intake and reservoir drain works.
This project is part of the reallocation plan for the plain. Therefore the existing irrigation system is fully redesigned, taking into account the optimal utilisation of the available water resources.
- The designed network covers an area of 160.000.000 m2.
- It is consisted of 9 irrigation zones, which are irrigated by pumping stations. Kerkini lake is the main supply reservoir providing water to all the irrigation zones through the main delivery canal.
- Downstream Control is used.
- The project includes a circumferential distribution water mains for the regulation of the tanks' supply and the ability for two-way water flow.
