Dissertation Project Status of Lakes in Hyderabad Indian Institute of Science
Introduction
• The Hyderabad city, founded in 1591 on the banks of river “Musi”
• Geographical location of Hyderabad is 17.366°N Latitude and 78.476°E Longitude.
• The city is situated at an attitude of 536 meters (1607 ft.) above sea level.
• The city lies in the Deccan Plateau, houses multiple lakes and large water tanks
• Since the twin city (Secunderabad and Hyderabad) were built on a rocky terrain, the potential for using groundwater is limited.
• The cities are dependent on surface water (lakes)
• But from last few decades, the water bodies are shrinking and disappearing.
• Their revival is an indispensable component for providing water security to the city.

Lakes In Hyderabad And Their Importance
Historical importance
Socio-Economic Importance
Ecological Importance
Dissertation Project Status of Lakes in Hyderabad Indian Institute of Science
• Many big tanks were built by the rulers to meet the water and irrigation needs of the city
• Many big tanks were built by the Qutub Shahi rulers (1534-1724 A.D.) and later by the Asaf Jahi rulers (1724-1948) in and around Hyderabad city.
• Some of the big tanks built during those periods are Hussain Sagar, Mir Alam, Afzal Sagar, Jalpalli, Ma-Sehaba Tank, Talab Katta, Osmansagar and Himayatsagar etc. (Rekha Rani, 1999).
• Most of the big tanks were constructed by the former rulers or ministers whereas the minor tanks were built by zamindars.

Some facts about water bodies in Hyderabad
3,245 hectares of lake area was lost between 1989 and 2001 (Anjal Prakash, executive director of Saciwaters)
Besides the large water bodies, numerous small water bodies in the peri urban zones also shrunk, when the city
underwent a wave of real estate growth (Ramachandraiah and Prasad 2008).
People have managed to destroy close to 50 per cent of the wetlands in the city in last 3 decades
Research based on satellite imagery shows water bodies coverage in the city has reduced from 2.5 % to 1.5%.
The Famous Hussain Sagar Lake, Mir Alam Tank which served as a source of drinking water during the Nizam’s time
has been completely polluted.

Reasons of encroachment
• City growth, industrial and urban spread
• Housing colonies are being constructed in dried lakes.
• According to the govt. rules, if the lakes do not receive water for three consecutive years and the lake remains dry, then the lake area comes under the jurisdiction of the Revenue Department.
• Non implementation of building regulations and pollution control laws
LAKES CONNECTIVITY AND THEIR ROLE IN PREVENTING
INUNDATION
Lake inlet and outlet to regulate its flow. A big lake is encompassed by
its’ large catchment area which contains a number of small lakes &
ponds. These small lakes and ponds are usually interconnected with
each other along with big lake which helps to maintain the hydrology of
these lakes. The interconnecting structures may be the Nalas or Storm
Water Drains.

Problems Faced By Lakes
Rapid Urbanisation And
Encroachment
ENCROACHMENT OF WATER CHANNELS
If encroachment occurs along with these nalas/ water channels, then it
will result in restricted flow of water which ultimately results in flood
during big storm events.
Further, the establishments along the nala/ Water channels discharges
their sewage and industrial effluent directly into them which
ultimately pollutes lake water. Apart from that, direct disposal of Solid
Wastes by establishment along the nalas, also causes pollution and
obstructs the flow in hydraulic structures like Interception &
Diversions, sewer lines, STPs etc.
Dissertation Project Status of Lakes in Hyderabad Indian Institute of Science
Industrial And Domestic Effluent
• Lake Foreshore attracts real estate business for its scenic value; leading direct discharge of untreated municipal and industrial waste waters.
• Almost 80% of Hyderabad's untreated sewage gets dumped into the city's lakes
• Hence the city's drinking water (Manjeera) now demonstrates an alarmingly high presence of excreta.
• municipalities surrounding Hyderabad discharge all the waste into drains and water bodies
• Pharmaceutical hub at Patancheru that releases a huge amount of chemical waste into the city's water sources
Solid Waste Dumping
• Water bodies are being used as debris dumping site.
• Regular dumping of huge amount of solid waste near lake area causes clogging and contamination, makes lake aesthetically unfit for the local residents.
• The HUA generates around 3379 tons of solid waste every day

Storm Water Drainage
• Natural and man-made drains and water bodies ultimately discharge surface run-off into lakes and pollute them.
• The nalas are the major carriers of storm water finally disposing into the river and water bodies in the catchment.
Idol Immersion During Ganesh Chaturthi
• Several thousands of idols immersion in lakes every year during Ganesh Chaturtji and DurgaPuja.
• The idols decorated with non-biodegradable products containing heavy metals like mercury and lead which are extremely dangerous to the ecosystem.
• According to the study, the immersion of Ganesh and Durga idols has polluted the lake resulting in vector transmitted diseases and lose of biodiversity and aquatic plants.

Dissertation Project Status of Lakes in Hyderabad Indian Institute of Science
• Lakes help in recharging aquifers and store the rain water.
• In Hyderabad ground water level has depleted due to loss of
water bodies
• Hyderabad is facing water crisis in several areas.
• Hyderabad’s early water sources - the Hussain Sagar, Osman
Sagar and Himayat Sagar
• The other important sources of water were the Musi and
Manjira rivers.
• River Musi is no longer a water source owing to heavy
pollution.
• Local self-reliance of water – breaks down
• Local water body sources – replaced by distant rivers –
Krishna, Godavari, Manjeera
• Consequences – expensive, larger eco-footprints

Effect Of Lake Degradation
Increased Instances Of Water
Logging And Flooding
Masab Tank• Situated at the southern foothill limit of Banjara Hills
• Converted into a thickly populated residential-cum-
commercial area.
• The downstream side of this tank has been
totally converted to residential areas such as
Vijaya Nagar Colony and Shanti Nagar.
• During rainy season- there is a problem of
waterlogging and flooding
Many water tanks Hyderabad have been
encroached and converted into residential
and commercial areas
Natural flow of the lake streams are
blocked, resulted in waterlogging and
flooding
August 2000 Flood in Hyderabad City
• Wettest spell in 92 years due to heavy downpour of rain.
• Many of the low-lying areas in Hyderabad were inundated.
• The severity of flooding was due to a Blockage of natural stream
leads and reduction in the carrying capacity of lakes and water
channels
Waterlogging hotspots during the recent rains, as recorded by
Hyderabad. Traffic Police

• Polluted lake causes vector transmitted diseases
• Causes health hazards in neighborhood.
• Fish caught from the polluted lake over a period of time is leading to serious diseases.
• The toxic substances can trigger chronic ailments.
• When organic compounds of mercury enter human body, they concentrate in the brain and destroy the cells which control the central nervous system.

Case Study I Hussain Sagar Lake
Built during: 1562 AD (450 years old)
Built by: Hussain Sha Walis
Basin area: 240 Sq. Km
Water spread area - 4.7 sq.km. and Shoreline Length - 14 kms
Purpose of building: to meet the water and irrigation needs of the city.
In the past 30 years, the lake has shrunk more than 50 % of its original
size (550 ha to 240 ha).
The quality of water in the lake has gradually deteriorated mainly due to
the continual entry of untreated domestic sewage and industrial effluent.
Other reasons of pollution are
• Cattle washing, vehicle washing, dumping of domestic solid waste
along the shore line as well as the immersion of large numbers of
Ganesh and Durga Idols during festivals
• Due to the eutrophication (overloading of
nitrates and phosphates), algal blooms and
bad odour, the water body is not
conducive for drinking water,
recreation & pisci-culture.
• The water from Lake Hussain Sagar is
now used for horticultural purposes after
treatment.
The main threat to the lake is encroachment by both private and
public agencies
STATUS OF LAKE It has recently been developed
into a tourist centre by HUDA

• In 2002 the lake was adopted for
rejuvenation under the National
Lake Conservation Programme
of the Ministry of Environment
and Forest (MoEF).
• Since then almost 2 cores has
been spent in rehabilitation and
rejuvenation of the Lake with
limited success.
• The Andhra Pradesh Tourism
Development Corporation Ltd
(APTDC) in association with Taj
GVK, situated in the lake
precinct, has developed a
conservation and management
plan. To prevent further pollution

Case Study III Noor Mohammed Kunta (NMK)
located on NH – 7 in the Shivrampally village,
Water spread: 27 acres
The lake is near Kattedan Industrial Estate (KIE) in
Rajendranagar, being surrounded by textile mills, edible oil
mills and other chemical units (in Katedan Industrial Area).
STATUS OF LAKE
Pollutants coming from industry has turned the water of lake
into a pink/ red colour. The NMK has been dead since years due
to heavy inflow of industrial wastes.
• NMK site was heavily polluted due to presence of heavy metals, organics, and inorganics and had been
identified as a ‘hot spot’.
• Both KIE residents and workers were exposed to health hazards
• Due to pollution residents are migrating from the lake into the research field of the Agricultural
University of Hyderabad are located downstream

Case Study III Noor Mohammed Kunta (NMK)
LAKE CONSERVATION INITIATIVES
Capacity Building and Industrial
Pollution Management Project
Funder: TheWorld Bank
Project implementer: Consortium of
Witteveen+Bos, Tauw, COWI A/S and
Kadam Environmental Consultants,
under the name of Pollution Control
Board Consultants (PCBC)
Project Timeline
NMK is the first and only lake in the country to have
been identified for cleanup by the World Bank-
assisted project on ‘Capacity Building and Industrial
Pollution Management Project’ by the MoEF and
approved by the Cabinet Committee on Economic
Affairs in 2010.
HUDA took up the construction of a sewage
treatment plant (STP) for treatment of domestic
sewage generated in the catchment area. The work
was completed in the month of January 2009 with an
expenditure of Rs. 6.95 crores.Remediation works were
supposed to start
In September
2013
The first phase will be completed by March 2014
The second phase will be
completed
by 2015-end.

PROPOSED REMEDIATION METHODS
Removal of toxic sediments
Construction of a sediment trap is recommended at the inlet
of the drains from KIE to the lake NMK.
Not only the lake should be remediated, also the sediment of
stagnant waters and open drains in KIE will have to be
remediated in order to clean the environment.
All highly toxic sediments would be dredged out,
dewatered and contained within tubes of geo-textile.
Waste Removal
Waste should be removed from the open (hillock) spaces to
prevent and stop ongoing dispersion of toxic substances to the
environment.
In KIE about 3,500 m3 of temporarily stored waste
will be collected and disposed to an off-site landfill for
Municipal Solid Waste.
Behavioural-based mitigation measures
Since it is not possible to remove all topsoil from the industrial plots and the open spaces, it is recommended only to
prevent further pollution of the site
Taking behavioural-based mitigation measures will help in reduction of lead and chromium health risks via soil
ingestion

Filling, Dewatering and refilling
The sludge is pumped into the tubes, and the
dewatering begins
The tube is left alone for a period of time
until it has dewatered enough so that more
sludge can be pumped into it.
The refilling can be done as many times as
necessary.
Disposal
Once it has been determined that the
dewatering process has accomplished the tubes
can be cut open and the solids can be
appropriately disposed off.

Way ForwardStrategic integrated management action plans and effective coordination between the different stakeholders
The national and state policies in respect of water and environment need to be integrated
Standards for lake and reservoir management have to be framed.
Restoration project needs to give emphasis on the restoration of the catchments of lakes.
Stakeholder participation and capacity building - an important instrument for better management of water bodies.
Active involvement of all the stakeholders like Corporates, Resident Welfare Associations, Education Institutions, Health organizations, NGOs and other agencies etc. – for speedy completion of the mandated works regarding Lake Protection and to ensure the sustainability of project
