Project Summary

Drinking Water-Irrigation
CONSULTANCY SERVICES FOR THE LAND RECLAMATION PROJECTS FUNDED BY THE THIRD SUPPORT COMMUNITY FRAME WORK OF THE MINISTRY OF RURAL DEVELOPMENT. COMPLEMENTARY ENVIRONMENTAL IMPACT ASSESSMENT STUDIES FOR THE PROJECT: FEREKAMPOU DAM, SKYROS ISLAND, EVIA PREFECTURE

Client: Ministry of Rural Development - Department of Land Reclamation
Year: 2004

ISSUE

The purpose of the study was the renewal and modification of the Environmental Terms of the project for the construction of the water dam of Ferekampos in Skyros Island and the water intake pipe from the torrent Ferekampos in order to satisfy the irrigation and water supply needs of the broader region.

SOLUTION     ΥΔΡΕΥΣΗ                                                                 View of Ferekampos earth dam

The water needs of the area were satisfied by wells. The extensive use of wells had a direct impact on the qualitative and quantitative composition of the groundwater aquifer.

The required works based on the modified designs included:

• Earth dam with a height of 23m, crest length of 245m and capacity of 1.050.000m3; the body of the dam consists of a pre-dam, a pseudo-core and support units upstream and downstream of the dam
• Drainage and waterproofing works
• Diversion pipe
• Water intake and outlet works with a length of 170m
• Spillway with a width of 20m
• Access on the upper part of the diversion pipe
• Installation of monitoring equipment
• Construction of a control building
• Installation of electromechanical equipment
• Access roadways

It must be noted that none of these works was constructed during the preparation of this study.

In the current study, the exact locations for the construction of the works were identified and the existing condition of the natural and human environment was examined which included new hydrological and seismological data.

Finally, the environmental impact from the construction and operation of the works was described and the mitigating actions during the construction and operation phases were provided. It should be noted that changes resulted from the modification of the technical studies did not induce additional impacts on the environment; they rather mitigated the already identified impacts.

BENEFIT

This project was submitted to the environmental public authority for the approval of the Environmental Terms. The project was constructed in light of the integrated water resources management in the region.
