Hydraulic design and hydrology reports of Patra-Pyrgos-Tsakona (PAPYTSA) Olympia Odos Highway

The new Patra - Pyrgos - Tsakona (PAPYTSA) Motorway follows, in general terms, the same route as the existing road. It travels south from Pyrgos to Kalo Nero and then turns east through the valley bounded by Mt. Tetrazio to the north and the Kyparissia mountains to the south, until it intersects the Tripolis – Kalamata Motorway at Tsakona, where the Olympian Highway ends. The main studies of this project were:
- Hydrology - Discharge determination of watersheds at several Geographical Units of Patra Pyrgos highway

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.

Extension of the water supply network of Karditsa

Design revision was necessary due to the network’s extension. The works included:
- The total network (old and new) consists of 2683 nodes and 3273 links.
- The range of selected diameters is varied between 60mm to 600mm of 120 Km total length.
- The design needs of the client required the provision and specification of measuring and control devices, water leakage detection and SCADA automated network control.

Revision of the Volos water supply network study

The revision concerns the pipe material, slight alteration of the pressure zones and details regarding the operational structure of the network, in order to facilitate water leak detection efforts.
The design specification require the implementation of proper measuring gauges and control devices, intended for the central SCADA automated network management and the facilitation of leakage detection.
The works include:
 - The model size is 10400 nodes and 15675 links, with a total length of 745km
