The committment to trust managment of Vorortan-Arpa-Sevan water-engineering system.
The main objective of the trust management of Vorotan-Arpa-Sevan Water-engineering System is to provide the transfer of maximum possible volume of water to the Lake Sevan with a view to increasing the water resources of Lake Sevan.
This objective is achieved by safe and trouble-free operation of 70 km long Vorotan-Arpa-Sevan tunnel conduit that would be ensured by operation and maintenance of
• 40 m deep intake shaft headworks;
• 5 shafts of different depths ranging from 90 m to 662 m;
• Kechut reservoir with its hydraulic engineering facilities:
- 47.3 m high earth-and-rock-fill dam and 234 m long water intake
- 30 m deep tunnel of the gatewell
- 40 m deep emergency shaft spillway with 270 m3/sec hydraulic performance
- 4 water gauging stations, wasteway chutes
• The intake and the system of offtake hydraulic structures on the Yeghegis River;
• 0.7 km long water supply canal to Lake Sevan from the outlet portal of Arpa-Sevan tunnel.
