Report on Financial Assistance required under SDRF for providing drinking water
supply during the year 2015-16 / 2016-17
Hyderabad Metropolitan Water Supply & Sewerage Board (HMWSSB) is providing
drinking water of 365 MGD for the entire area of GHMC including certain villages and 4
No's of municipalities enroute. The supply meets the requirement of all State and
Central Government institutions including Defence establishments, Secunderabad
Cantonment Board etc. and industries like BHEL,ECIL, HCL etc.
Due to failure of monsoon this year (June to Till now ) water levels in Singur,
Osmansagar, Himayat sagar and Nagarjunasagar sources have considerably reduced
when compared to the last year levels as shown in the following table as on 30.11.2015.

It is anticipated that there will be severe water crisis for the months of December till
next monsoon.
Bore wells which used to supplement the water requirements have likely to go dry
because of drought condition prevailing in the State. Hence, the problem will be further
compounded.
Power breakdowns, are likely to cause further dislocation of water supply services
because water supply in Hyderabad is predominantly dependent on pumping system,
since Krishna and Godavari are power dependent sources. The following contingency
plan is worked out to address the issues during the year 2015-16.
ACTION PLAN:
At Osmansagar reservoir the present level is 1757.290 ft. as on 30.11.2015. From 1-05-
2015 onwards 05.00MGD water is being drawn instead of normal 25.00 MGD with the
arrangement of Emergency pumping and it is sufficient upto 28-02-2016.
At Himayathsagar, presently 5.00 MGD is being drawn by gravity upto 31-12-2015 and
later with the arrangement of Emergency pumping and the available water is sufficient
upto 30-06-2016.
The present level in Singoor Dam is 510.787 mts and the water at 120.00 MGD was
drawn from 20.05.2015 with the arrangement of emergency pumping upto 30.11.2015.
At present only 20.00 MGD is being drawn and the available water is sufficient upto 31-
03-2016 and water from dead storage can be drawn with arrangement of secondary
pumping arrangements.
The present level in Nagarjunasagar reservoir is 509.000 ft and the water at 247.00
MGD is being drawn at present. It needs to draw water by emergency pumping
arrangement once the level touches 505.00 ft and needs secondary pumping
arrangements once the level goes beyond 500.00 ft.
Due to low levels in the reservoirs it may not be possible to provide piped water supply
to certain elevated locations and needs to provide the water through tankers.
HMWSSB will also take up repairs to the existing bore wells and convert the hand bore
wells to power bore wells wherever water is available.
HMWSSB will take up installation of static tanks at new locations where piped water
supply is not possible and alternate arrangement for water supply is required.
Power breakdowns are likely to be experienced during the year and require generators
at certain pumping houses and chlorination plants to ensure continuous pumping during
local load shedding and power breakdowns of CPDCL.
Due to depletion of water levels, water drawl from the dead storage are likely to contain
high turbidity, growth of algae, etc which may require special treatment procedures
including use of chemicals like Activated Carbon, Non-Ferric Alum etc., to address water
quality issues.
It needs diversion of Krishna/Godavari water to Manjeera system at Lingampally
reservoir premises, Hydernagar reservoir premises, at Shaikpet and other locations so as
to meet the short fall in Manjeera system.
