ISSUE
The purpose of the project was the approval of Environmental Terms for the construction of the required flood protection - drainage and rural roads works east of Lake Vistonida, in order to establish flood protection for the region in relation to the protection of lakeside areas,  adequate sewerage - drainage of agricultural lands contained within the boundaries of the area and adequate road service within those areas with the provision of rural roads network, properly connected to the existing community and rural roads.

SOLUTION                                                                                                                  Wider area view
The proposed works included the following:

• The lowland settlement:

1. of rivers Kompsatos (Iasmos), Travos (Aspropotamos) and part of the river Kosinthos (Xanthi)
2. of torrents Amaxades (western and eastern sector), Pistos, Asomaton and other smaller watercourses in the area east of Lake Vistonidas.

In the above arrangement works riverbed excavation, filling, protective embankments, slope protection arrangements and gabions were included.

• The construction lakeside embankment, 14km in length, along the shores of Lake Vistonida.
• The construction of sewerage - drainage network with trapezoidal in cross-section ditches and associated structures (culverts, crossing works, exit works, confluence works, bends, slope protection arrangements on ditches).
• The construction of eight (8) sewer pumping stations along with their electromechanical equipment.
• The construction of rural road network in parallel and along the river embankments, streams or watercourses and along parts of the lakeside embankment with the required crossings.
• The improvement of Porto Lagos - Komotini highway part from Kallisti to Komotini new airport site, 14km in length, which mostly runs in parallel to the left embankment of River Travos.
• The simultaneous implementation of small works in redistributed areas eastern of Lake Vistonida.

In the accounted study the exact locations of the construction works were identified while the current situation was analyzed, investigating of the state of the natural and human environment. At the same time significant information was offered with respect to the feasibility of the works along with their analytical description.
 
Finally, the extent and size of the caused environmental annoyance from the construction and operation of the works was described, while appropriate methods to treat environmental impacts during construction and operation phase were provided.

BENEFIT
The study was submitted to the department responsible for environmental licensing of the proposed works.
