Emergency pumps dusted anticipating water crisis
They will be used if the KRS water-level dips to 70 ft.
Anticipating a drinking water crisis in summer owing to
the fall in the water-level at the Krishnaraja Sagar, emergency pumps
that were last operated a decade ago have been kept ready.
The pumps would be pressed into service only when the water-level in the dam falls to 70 ft.
On Thursday, the water-level stood at 75.8 ft against the maximum of 124.8 ft, according to official sources here.
Two
turbine pumps, a centrifugal pump and two pumps (with capacity of 100
hp and 200 hp respectively) had been overhauled for emergency pumping
from the riverbed near Hongalli, about 15 km from the city. “About 50
mld (million litres per day) of water can be drawn from the riverbed
daily using these pumps,” said sources in the Vani Vilas Waterworks,
Mysore. Hongalli pumping station has a capacity to pump 90 mld. “If the
water level falls to 70 ft, water cannot be pumped from the right bank
low-level canal. This reduces the amount of water pumped by at least 45
mld,” the sources said.
They pointed out that the infrastructure was ready and power supply had also been restored.
The
water pumped from the riverbed would be drawn to the main treatment
plant and, thereafter, supplied to the distribution system.
“Steps
have been taken anticipating severe water crisis this summer due to
failure of monsoon,” they said, adding that rationing of water to some
areas would become inevitable if pumping from the riverbed became
inevitable.
However, the situation might improve if
there were summer showers in March, they added. The Mysore City
Corporation has sought Rs. 2.8 crore from the State government to take
up emergency steps to ensure drinking water supply in the city during
summer. “A sum of Rs. 30 lakh is necessary to operate the emergency
pumps,” the sources said.
If there was a crisis,
water would be supplied through tankers to the scarcity-hit localities.
If required, borewells would be deepened and hydrofractured to improve
water yield. Some localities such as Vijayanagar are supplied borewell
water.
Of the 1,490 borewells in the city, only 850
are active. Of them, about 90 were not being used after the Kabini
drinking water project was commissioned.
This project supplies 40 mld to some parts of the city. The Melapura drinking water scheme provides 70 mld.
