In the context of the specific Public-Private Partnership, the Private Partnership Body (IFS) will implement the design, construction, financing, operation and maintenance of the Havria Halkidiki dam, the water treatment facilities (Ε.Ε.Ν. ) and external water supply networks – Phase A ‘. In short, the I.F.S.

1) prepares the studies necessary for the construction design of the project, based on the applicable environmental conditions, and arrange and expedite the obtaining of all necessary permits;

2) constructs the whole object of the construction design studies, with the aim of the full operational efficiency and readiness of the project;

3) will undertake the operation and maintenance of the project, in accordance with the requirements of the partnership contract, the performance specifications and the operation and maintenance plan approved by the contracting authority, which will be prepared by the IFS;

4) will return the project to the Greek State, in accordance with the provisions of the contract, at the end of the contract period, in exchange for the payment of availability payments, during the operating period.

In particular, the subject of the partnership agreement concerns the construction of the following infrastructures:

1) the Havria Dam and the accompanying technical works;

2) the Water Treatment Plants (EEN), with a capacity of 55,000 m3 / day, and

3) external networks with a total length of 62 km, tanks and pumping stations.

In the context of the partnership, the I.F.S. will be responsible for financing the project, while the contracting authority, throughout the partnership, will make annual payments (availability payments), according to the relevant payment mechanism performance, which will be included in the partnership contract and will be based on quality standards, (in this case, in particular as regards the operational availability of the project, with a specific quality level of results, ie the performance specifications of the partnership contract).

It is pointed out that the management of the PPP project from the I.F.S. starts from the head project (dam) to the reservoirs of the settlements. The quantitative distribution of the refined water in the local D.E.Y.A. and the pricing of water supply services to the local DEYA will be done by the management body, which is expected to be proposed and then set up, based on a special study. The construction duration of the technical project is estimated at a maximum of three (3) years, at most.
