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 works included:
- 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 consists of the following individual works:
- The main embankment dam
- The spillway (collector, spillway canal, flip bucket, plunge pool)
- The diversion works which are combined with the intake and reservoir evacuation works.
Specifically:
- The dam is 48 m heigh with an impermeable core. The embankment cross section is trapezoid with a 2:1 (v:h) slope inclination and upstream-downstream berm provision.
- The diversion works are formed prior to the main fill construction. The 4mx4m rectangular culvert is 377 m long.
Designed works include:
- A main water intake steelpipe is 2500mm, combined with a hydroeletric power generation plant.
- Three main delivery pipelines are provided with diameters of 1600, 1400 and 1200mm. Material proposed is steel. Total length of the main pipelines is 47km.
- The pipeline design includes all main pipelines.
- The network also incorporates numerous regulating devices and management installations, in order to ensure optimal operation.
- The area covered is 25.200 ha (252 km2).
