The Surya Regional Water Supply Project has achieved a milestone by
completing the tunnelling work of the Tungareshwar tunnel recently. The 4.6
km long underground tunnel for crossing the Tungareshwar wildlife sanctuary is
now finished.
The internal finished diameter of the tunnel is 2.85 meters. The water will be
channelled through this tunnel to the Chene Master Balancing Reservoir (MBR)
and distributed to MBMC.
The tunnel excavation was carried out using a modern Tunnel Boring Machine
by constructing two shafts of 10 meters in diameter at the inlet and outlet for
lowering of the TBM. The tunnelling scope of the Surya project involves a total
of 4 tunnels. One tunnel in Phase-1 and the other three tunnels are in Phase-2.
The tunnel in Phase-1 at Mendhwankhind is ready for water supply.
