Consultant for assisting DEYAK in the preparation of the application file and the submition of the relevant application for funding of the Treatment and Disposal of Sewage Sludge works of the Wastewater Treatment Plant (WWTP) of the Municipality of Karditsa. General plans and basic design plans of proposed works. Assistance in Project Data documentation (scope determination, losses estimation report etc).
The Technical Consultant assisted in:
Xerias river basin has an area of 174 km2 and extends from the town of Korinthos (North) to the Southern districts of the Korinthos Prefecture, at the frontier with Argolida. Xerias river flow is seasonal with intense fluctuations. The January 1997 storms caused serious disasters.
The works included:
- Open and closed parts combination with composite concrete/steel sections, 1330m long.
The project includes the dam, spillway and energy dissipation, water intakes and road access.
The dam and reservoir lies within the private Porto-Carras areas. The main structures are:
- a lean RCC dam with a height of 32m and volume ~40.000 m3
- a spillway with capacity 330m3/s
- a 4 level water intake structure
The reservoir has total capacity ~1.000.000m3
A set of necessary works are suggested, along with water conservation and environmental objective target measures.
A full exploration of possible solutions is carried out in the Water Resources Management study, including hydrological and resources modeling.
The works proposed include
o Dam 56m high, earthfill
o Dam 32m high, earthfill or RCC
o Water treatment Works (major) for 100.000 EP
o Water treatment Works (secondary) for 40.000 EP
The future water needs of Rhodes will be covered by Gadouras dam and reservoir. This project covers the final design stage of all the water mains and other structures necessary, from the reservoir to the regulating tanks of the water supply network of the city of Rhodes.
The works included:
- Construction of a steel pipeline of diameters varying from Ø1300 to Ø800, with a total length of 50km, including an 800m tunnel
- Construction of a maintenance access road
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
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).
