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: PANORMOS LAKE RESERVOIR ON SKOPELOS ISLAND, MAGNISIA 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 lake reservoir of Panormos on Skopelos Island in order to satisfy the irrigation and water supply needs of the broader region.

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

The construction of the lake reservoir was proposed at the north-western part of the island of Skopelos, north-east of community Panormos, within the river bed of Panormos torrent, approximately 1km prior to its discharge to the sea.

The required works based on the modified designs included:

• Construction of the in-river lake reservoir with effective capacity of 152.000m3, surface area of 30 hectares and construction of the dam
• Spillway conduit made of reinforced concrete with a length of 1000m
• Diversion pipe with a length of 140m
• Water intake and outlet pipe with length of 140m
• Side spillway with a length of 16m
• Construction of the building for the valves, pumps and instruments
•  Construction of access roadway
• Construction of the works for sediment retention (river terraces)

It must be noted that none of these works was complete during the realisation 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.
