Hyderabad: As the State capital continues to reel under sweltering heat, the water table in its premier reservoir, Osmansagar, is giving cause for concern. Alarmed at the depleting levels, the Water Board has erected four emergency pumps and is expected to operate them shortly. On Tuesday the, reservoir had 0.233 tmcft water as against 0.807 tmcft same day last year.
In view of the plummeting levels, the drawal of water from Osmansagar by gravity has come down from 22 mgd to 16.8 mgd during the last one week. Supplies from Osmansagar can continue for another one-and-a-half months, but with further reduction in drawal to 12 mgd and even 10 mgd.
“Any further drawal after this level is not considered advisable as the water will be muddy,” says C.V. Rama Baba, Director (Operation I).
Of the four pumps installed one is kept as standby. The pumps are of 100 HP to 150 HP capacity. Only after June 1 the Water Board is expected to start emergency pumping when the drawl by gravity comes down to 15 mgd.
There is, however, no cut in the quantum of supplies to areas served by Osmansagar as authorities have started supplementing through Krishna water. The position in the other reservoir, Himayathsagar, is comfortable. It had 0.977 tmcft water as against 0.491 tmcft last year. Authorities are confident of continuing supplies from this reservoir up to September without any problem.
In Singur too, emergency pumps have been installed and they are expected to get operational by June end. At present 120 mgd is being drawn from here. Despite the grim situation, authorities exude confidence to maintain the present supply of 332 mgd.
