YEREVAN, February 19. /ARKA/. Repair work in Arpa-Sevan tunnel will be completed in the next two years, said Artashes Ziroyan, head of bioresource management agency, Armenia’s ministry of environment.
Arpa-Sevan is still one of the most important problems in the sector, Ziroyan said Tuesday, at a discussion on effects of discharges from the lake.
Repair work that started in September 2010 is carried out by Arpa-Sevan Armenian company. A total of 11.8 billion drams only were allocated for the work, of it 6 billion has been already spent.
Ziroyan said the tunnel repair will allow supplying water to Sevan Lake on a permanent basis and raising water level by more than 20 centimeters every year.
The 48.3-kilometer-long tunnel supplying water from Kechut reservoir to the lake was constructed in 1961-1981.
Lake Sevan, one of the largest alpine lakes in Europe and Asia, is located in the heart of the Armenian plateau, at an altitude of 1,914 meters. The lake stretches over 70 kilometers from northwest to southeast. Its water surface area is nearly 1500 square kilometers. The lake is the main source of drinking water in the region. The water level in the lake will be raised to the optimum 1,903.5 meters by 2030. –0—
