Highway design for the update of the New National Road into a Highway (ΠΑΘΕ), section: Stylida - Raches (Chainage 12+000 - 32+000)

The stormwater and drainage works design of the 180km2 basin refer to :
- The main higway, 19.235 km long
- Three (3) tunnels,
- Four (4) valley bridges,
- One (1) bridge (Vellias stream)
- Three (3) overpasses
- Eleven (11) underpasses.
- Three (3) interchanges : (α) Ag. Marinas - Stylidas(β) Stylidas - Karavomilou (γ) Karavomilou - Ahinou.
- Sideways and other local roads
- Temporary works during construction period.

Final study of the primary and secondary irrigation and drainage network of area II in Serres

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.

Technical consultant for the Amira-Ag Vassilios dam

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.

Design of the water supply extension of the Gadouras dam pipelines

The project involves the extension of the existing pipeline to a wider area, covering potable water needs around the island, substituting weak underground resources.
The pipeline design extends to a total of 130km and includes numerous related infrastructure such as control tanks and devices and pumping stations.

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).

Stormwater and sewage network study of the Communities of Ekali, Drosia, Stamata, Rodopoli, Anixi, Ag.Stefanos, Dionisos and Krioneri

The project areas belong to the Municipality of Ag.Stefanos and the Communities of Ekali, Drosia, Stamata, Rodopoli, Anixi, Dionisos and Krioneri. The study areas are situated in the upstream part of the northern suburbs of the Attica basin and they have 12 basic streams, 7 of which fall into Kifissos river and the other 5 in the lake of Marathonas (Haradros river basin).
Major design problems were erosion and high sediment yield. The project design takes into account the environmental protection restrictions of the surrounding area.
