Lakes do the disappearing act

Saturday 29 September 2012

Several lakes in Hyderabad have shrunk or vanished due to encroachment and pollution

Markers for the Full Tank Level have been moved to allow builders to 'reclaim' part of the Ganga cherevuHyderabad once had more than 3,000 lakes in its urban conurbation. Today, only about 500 exist, according to the Hyderabad Metropolitan Development Authority(HMDA) data. In the first quarter of the 20th century, the city depended on Himayat and Osman Sagar, lakes now within city limits. But over time, reliance on them waned as lakes shrunk due to unchecked encroachments, particularly after the real estate boom of the early 1990s. Due to incessant discharge of untreated sewage, they turned into cesspools. Now, city authorities get water from a source more than 100 km from the city.

How water sources moved away from the city


“We have no choice because lakes are no longer a sufficient source, either in quantity or quality,” says Maheedhar Reddy, state minister for municipal administration and urban development. Besides, “there is massive pollution and encroachment of waterbodies in the city,” says Kumar Gupta, member (environment) of HMDA. At present, the authority is drawing conservation plans for a fifth of those lakes that officially exist.

According to officials in the Hyderabad Metropolitan Water supply and Sewerage Board (HMWSSB), 700-800 million litres a day (mld) of the city’s untreated sewage finds its way into waterbodies in and around Hyderabad. While most households in the core city area of 165 sq km have sewerage facilities, sewage generated from households located in the periphery areas discharge wastewater into open drains. “To bridge this gap, we have plans to enhance the sewage treatment capacity by 600 mld in the next few years,” says M Satyanarayanan, director (projects), HMWSSB.

'Developer-official nexus at work'

Studies show that 3,245 hectares of lake area was lost between 1989 and 2001, says Anjal Prakash, executive director of Saciwaters, a Hyderabad-based non-profit. “Although research shows that majority of this loss is on account of encroachment, we plan to undertake a ground reality study to understand the extent and reasons for this loss better,” he adds. Research based on satellite imagery shows that waterbodies once covered 2.5 per cent of the city area. This has now reduced to less than 1.5 per cent.

“How else can you explain showers, say 10 mm, inundating parts of the city. Water has no place to go as land sharks have encroached lakes and their catchments,” said Jasveen Jairath, convener of Save Our Urban Lakes, a campaign front in Hyderabad. Jairath gives several examples, most notable among them being the Nadeem Colony where houses are built on the lakebed. “It is no surprise then that these homes get flooded each year,” she adds.

House in Nadeem Colony built inside a lakeTo prevent further encroachments, the Andhra Pradesh government formed a Lake Protection Committee in 2010 comprising officials from the concerned government departments. The responsibility to install full tank level stones was given to the revenue and irrigation departments in order to identify and remove encroachments. As per a 2010 government order, all constructions 30 metres from the full tank level must be removed. But companies continue to disregard such orders. “We are campaigning against this blatant defiance of law,” says Jairath.

A hotel built illegally on stilts on the Ganga cherevuIn many cases, construction work is on within no-go zones. “Around Ganga cherevu (lake) in Miyapur, land 10 metres from the marked stones has been excavated and is being de-saturated by pumps round-the-clock for an apartment complex,” says Bhaskar Reddy. He has filed a case in the high court to save the lake. Despite the heavy rains in August, says Reddy, the lake did not spread because the bund was deliberately damaged to prevent water from accumulating. The irrigation department, in cahoots with the builders, often shift the stone blocks indicating the full tank level further in, he added. Irrigation department officials refute this outright.

The committee has suggested that the size of the stones be increased so that they are not easily moved. In the last meeting of the committee, held in March earlier this year, it was decided to note the markings of the indicator stones in case of damage or removal. Nearly 150 lakes, according to the irrigation department officials, now have in place full tank level stones. The committee has not met since their last meeting, as the department is busy preparing for the Convention on Biological Diversity that will be held in the city from October 8 to 19.

There is consensus among committee members that the quality of lakes be monitored periodically and uploaded on its website. There is little clarity on who will monitor which lake and who will bear the cost. The irrigation department has said that 50 lake memoirs, detailing history and characteristics, will be prepared by the year-end.

  • Yes, it is the reality.

    Yes, it is the reality. Knowing very well by the people at all level still it is going on. Another SAD example is famous Hussain Sagar. In spite of its unhealthy situations, still it is seen and enjoyed by the people. Then where is the problem. I am seeing this issue since 1979 and things are going worst. Situation is known, data base is available, technologies are available, several studies have been carried out and spending lot of money. Every one knowns about this, still beautification is going on.

    Then the big question comes who will initiate the work. It is the PEOPLE, and the COMMUNITY should make initiation for the protection and conservation of the WATER Bodies. The situation in Hyderabad for WATER is alarming and sustainable solutions should be taken immediately.

    Hope better ways of utilization and conservation of WATER bodies will help to maintain an HEALTHY ENVIRONMENT which check the GLOBAL WARMING / CLIMATE CHANGE and further controls the BIO-DIVERSITY.

    The ongoing Convention known as CBD or COP 11 should also thinks about this issue as WATER is the most precious natural resource which controls every thing on this EARTH / UNIVERSE.

  • The disappearance of

    The disappearance of water-bodies - especially, urban - is happening in Kochi. The Vempanad backwaters, which is a site declared protected under Ramasar Convention, are constantly shrinking thanks to the development strategies and patterns adopted by the state, and the callous attitude by which urban population treat the precious heritage.
    The easy way in which Greater Cochin Development Authority found funds for building bridges across the water body to connect Vypeen islands was to claim land from the existing water body - initially some 2000 hectares, reduced to somewhere around 300 ha thanks to the protests by environmental pressure groups.
    Every individual, especially the nouveau riche who have obtained water-fronts from the natives, have taken meters of land into the water body.
    New roads are being suggested by the middle class and the urban planners, where the water body becomes the casuality. Thanks to the constructions in the water body to further strengthen the Wellingdon Island where the Cochin Port is housed, the sedimentation that happens through the floods and tides lead to further conversion of water body into land. Even mangroves start growing where they were not some decades ago, leading to those patches becoming land area.
    Unauthorized urban slums set up by various settlers with the support of local politicians or local branches of the political parties, have also led to a large tracts of conversion of water body.
    Municipal authorities, at some point of time, took the easy way of filling smaller canals for roads, and laying pipes in the landfills, in stead of building bridges, which have also led to many sections of the water body getting cut-off, leading to conversion of those areas, and water-logging.
    It is quite hurting to notice this and feeling helpless to do something about it.
    A local movement is emerging in Thevara which is trying with the help of court intervention to regain some tracts of the filled land.
    Glad to see the analysis on Hyderabad, where my good friend Anjal Prakash is also involved
