- Construction of a maintenance access road

Karla natural lake refill

The project mainly consists of a water resources management study. The Karla basin (1,000km2) with its current status and use of surface and underground resources is evaluated.
Part of the current use is pumping of subsurface water for the supply of the greater Volos area, the largest nearby city with a projected future population of 150,000.
- In this study the water budget was examined, taking into consideration all surface and underground resources, along with the river Pinios flows

Design of the Smokovo irrigation network

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.
