Monitoring system at HTC Dolno Ezero

The project is located east of the Zlatna Panega village in the municipality of Yablanitza, province of Lovech.
The complex was build in 1927 and the facility was upgraded several times over the years but without being subject to major rehabilitation.

HTC Dolnoto Ezero is a main element of the water supply system Zlatna Panega for drinking and domestic water supply of 13 villages and towns or more than 28 000 people situated in the municipalities of Lukovit, Yablanitza and Cherven Bryag.
