Design of an RCC dam and related structures for the Porto Carras resort in Halkidiki

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

Technical Consultant for the preparation of a water supply masterplan for the island of Lesvos

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

Design of water supply works (pipelines-treatment plant) for Athens

Designed works include:
    o A main 6.25Km long external pipeline with diameter 1700mm and 5.5 m3/sec flow rate.
    o Capacity audit of the 13Km long Mpogiatiou water tunnel (constructed in 1930) for flow rate Q=10.0 m3/sec. Design of:
       ▫ Water works for the connection of Mpogiatiou water tunnel with the grit removal tank
       ▫ The grit removal tank
       ▫ Power plant station including a water energy production turbine and a D1700mm pipe.

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.
- The area covered is 25.200 ha (252 km2).

Final stormwater network study of the Community of Anixi

The area belongs to the Community of Anixi and is situated at the upstream part of the Northern Suburbs of the Attika basin. The project includes the construction of a stormwater network and rehabilitation/maintenance of existing pipes.
The project design takes into account the environmental protection restrictions of the surrounding area.
The works include:
- The network length is 4,3 km
- The main technical works are circular pipes Φ400 - Φ1400 and maintainance, junction, drop manholes.

Design of water infrastructure for a major port facility

The wastewater collection works include the main sewers pipeline, pumping station and twin pressure mains.
The wastewater treatment plant includes the full extent of necessary substructures designed to provide for the 3-stage treatment of an 18.000 equivalent population of industrial wastes. The project  included the full spectrum of civil and mechanical engineering design.
The final discharge pipes include the collector pipe transporting the effluent from the WWT plant to the sea, incuding an underwater pipeline and all the auxilliary structures.

Aposelemis dam, water treatment and supply works in northern Crete island

The dam is 56 m heigh. It is of rockfill type with an impervious clay core, upstream and downstream rock cells, spillway, spillway delivery canal and flip bucket
- The Lasithi plateau diversion to the Aposeslemis reservoir includes a TBM excavated 3,5km long and 14% steep tunnel
- The water treatment plants include pre-ozonation, coaggulation, sedimentation, filtering, post-chlorination and sludge treatment
- The main pipelines from the dam to the water treatment plant, ~ 8 km long, consist of D1200 and D1100 steelpipes and 2 tunnels (1590, 2050m long).

Gadouras dam, water treatment and supply works in Rhodes island

The project includes the Gadoura dam and appurtenant works construction, the water mains to the town of Rhodes (including a small tunnel), the water treatment plant construction.
The project will service the long-term region water supply needs.
The project is funded by National Sources and the E.U.
The dam height is 60m. The embankment dam is earthfill type with an impervious core and the reservoir capacity is ~65 hm3.
