PURPOSE OF BHATSA DAM

7. Gravity Dams Gravity dam is the one in which
the external forces (water
pressure, wave pressure, silt
pressure) are resisted by the
weight of the dam itself
These dams are heavy and
massive wall-like structures of
concrete in which the whole
weight acts vertically
downwards
Reservoir
Force
As the entire load is transmitted on the small area of foundation, such dams
are constructed where rocks are competent and stable.
Self weight

8. Earth Dams:
They are trapezoidal in shape
Earth dams are constructed where
the foundation or the underlying
material or rocks are weak to
support the masonry dam or where
the suitable competent rocks are at
greater depth.
Earthen dams are relatively smaller
in height and broad at the base
They are mainly built with clay,
sand and gravel, hence they are
also known as Earth fill dam or
Rock fill dam

19. Gate Control Room
For the centralized operation of the
spillway radial gates from the
control room, centralized hoist
motor control cubicle with
automatic and
manual interlocking is provided in
the control room.
The Gate Control system can be operated from the master control
station through the VHF network, which is a two way communication
media.
The Gates can be operated to manage the water outflow
The Gates can be also be operated manually from the Dam control
station, using the control system.

Vajra Fall Hydro-Power plant is power station located on Bhatsa river
approximately 6 km downstream of the Bhatsa dam near Shahapur, Thane
District in Maharashtra.
This plant supplies power to M/s. Tata Consultancy Services, utilizing the
Maharashtra State Electricity Boards grid, under open access policy. The
power is evacuated on a 100 KV line and injected line Maharashtra State
Electricity Distribution co. Ltd. Sub-station at Kumbhare.
