Bulgaria - cleanup of the reservoir, civil works and installation of 55 000 m2 synthetic geomembrane insulation layer on the reservoir surface.
The Petrohan reservoir is a major storage of water for the hydropower peaking cascade, consisting of three utilities with total head of nearly 800 metres. The reservoir suffered from extensive leakage, causing structural problems, capacity constraints, and local obstructions.
The scope of the project included cleanup of the reservoir, civil works (reservoirs amendments) and installation of 55 000 m2 of new synthetic geomembrane insulation layer on the reservoir surface.
HYDROPOL was a turnkey contractor of all works, delivering the project within July - October construction season in the elevation of 1 500 m above sea level. Dam height is 5 m with an upstream face surface area of 50 000 m2.
