Project review

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.
