Bangalore: L&T Secures Orders For Rs.581 Cr

Larsen & Toubro said that it secured orders for Rs.581 crore from Powergen Infrastructure and Bangalore Water Supply & Sewerage Board during the third quarter of the fiscal. The orders include an EPC order for the material handling business for Rs.392 crore and water business for Rs.189 crore.

The projects will be executed by the metallurgical, material handling and water operating company of L&T’s construction division

The company said that the contract from Powergen Infrastructure is for setting up of a coal handling plant at 5 X 660 MW Tiroda Thermal Power Plant of Adani Power in Maharashtra and is to be completed in 30 months. The project includes basic and detailed engineering, supply and erection of mechanical, electrical and instrumentation systems and structural steel works including testing and commissioning.

The contract from BWSSB includes fabrication and laying of mild steel pipeline. The scheme is funded by Japan International Cooperation Agency, envisages transmission of 500 million liters per day of clear water from river Cauvery to Bengaluru. The project is to be completed in 24 months.



Bangalore: BWSSB- Digging hard for Drinking Water

ALL the sources of drinking water in and around Bangalore will not be able to quench the city’s thirst in the next 30 years. Estimates suggest that Bangalore will need at least 2,550 MLD of water by 2040. Even if all the sources of drinking water are exploited, only 1,500 MLD of water will be available for the city.

Looking down the barrel on the unavoidable fact, the Bangalore Water Supply and Sewage Board (BWSSB) amended the BWSSB act 1964 on August 27, 2009 to make way for rain water harvesting as a source of water for the city.

If the plans are implemented according to the amended laws, the harvested rain water is expected to meet the water requirements of the city for nearly six months in a year.

The BWSSB managed to supply Cauvery water to 16,000 households in the newly added areas of the city this year. More than 1,000 bore wells were dug to supply drinking water to these areas.

To bring in more water for the city, the department awarded most of the contracts for the implementation of Cauvery IV Stage II project and officials say the project will be completed in time — by 2012.

The water wastage has been causing a major dent in the department’s revenue. BWSSB has installed bulk flow meters to monitor the flow of water in different areas and to check the wastage of water. The geographic information system that is being currently developed is expected to help the department in checking the unaccounted for water. BWSSB has undertaken two major pilot projects to study the feasibility of implementing the system. The first of the two is expected to help the department trace the leakage in the city through satellite imagery.

The jetting machines inducted for clearing blockages in the sewage lines have proved effective.

BWSSB is also in the process of laying 2,300 kms of sewerage lines in the new areas of the city with World Bank aid. This project is expected to take shape in 2010.

Around 72 kms of major sewage lines were laid to ease the sewage flow from the city this year.

Bangalore looks beyond Cauvery Water to quench thirst

The city is examining options, including rainwater harvesting.

Bangalore, which draws all its drinking water from the Cauvery has been lauded as a model city for its well-metered water supply system and an effective complaint redress mechanism.

The city, also an information technology (IT) hub, has metered its water supply and made its revenue collection allegedly leak-proof, with solutions provided by IT companies in its 580,000 water connections in a population of about 7.4 million.

But Bangalore is now on an expansion mode, with a new supply line being readied for the Greater Bangalore City Corporation, which will include seven city municipalities and one town municipality.

To meet its future requirement, the city is looking beyond the Cauvery. It is examining the options of supplying water tapped through rainwater harvesting, as well as a different model for funding the new project.

There are various options for managing supplies, including end treatment, source treatment and roof water harvesting, says K V Raju, economic advisor to the chief minister of Karnataka, and professor and head, Centre for Ecological Economics and Natural Resources of the Institute for Social and Economic Change.

He says these could take care of 40 per cent of the needs of the city, which receives about 1,000 millimetre of rains every year.

In addition, recycled water would ensure there is lots available for local consumption. But, for that we will need to lay a second pipeline to deal with the accessibility issue, says Raju.

The actual demand-supply gap for water in the city is around 10 per cent as far as the Bangalore Water Supply and Sewerage Board (BWSSB) is concerned. But, a significant amount of water distress is seen in the city because of the private layouts and developments that have come up around the city.

Despite the issues pertaining to water supply, Bangalore is said to have the best metered water connections among the metros. “No city in India has metered better than Bangalore. This ensures better accountability and revenue models,” said Raju.

The current per capita water supply in Bangalore is 100 to 125 (gross) litres per capita per day (LPCD), which is below the national standard of 150 LPCD. The per capita availability of water for the vast majority of poor people in Bangalore is only 40-45 LPCD. The gross demand for the city’s population is 900 million litres a day (MLD). However, BWSSB is able to supply only about 810 MLD.

According to M N Tippeswamy, a retired chief engineer of BWSSB and now a consultant with the board, there is need for a catchment area authority in Bangalore, like the Sydney Catchment Authority in Australia. But, the multiplicity of agencies is a hurdle to any projects for protecting the catchment areas.

BWSSB spends 55 per cent of its budget on power, 12 per cent on establishment costs, 3 per cent on chemicals, while revenue expenditure makes for about 15 per cent and rest goes on repayments.

The reforms undertaken by BWSSB are the first steps towards increasing its financial resources, enabling an investment in the automation of systems such as accounting processes.

Administrative reforms have set the pace for the financial reforms at BWSSB, as well as for streamlining its accounting processes. Meanwhile, the utility also worked on improving its relationship with the public. “The provision of spot billings and 24-hour automated payment kiosks has increased customer friendliness,” said a top ranking official. The Board is also moving towards adopting international accounting standards to improve its credit ratings.

About 90 per cent of the water supplied by the BWSSB comes from the river Cauvery. Water is pumped over a distance of about 100 km to the city, which is 3,000 feet above sea level. The scheme nominally supplies 810 MLD to the city. The second phase of Cauvery Stage-IV, which is under construction, is expected to enhance the water supply by another 500 MLD.


Bangalore: Water treatment plant at T K Halli

French company, Degramont, will set up a water treatment plant at T K Halli at the cost of Rs 329 crore, to treat 500 million litres of water daily from the reservoir, said Narayana, Additional Chief Engineer (Cauvery), BWSSB. 
Speaking to reporters Narayana said the contract, part of the Cauvery Water Supply Stage IV, Phase II, had been awarded to the company on December 1. The company was already a part of the first phase of the project, he added.

The second phase is slated to be completed by 2011. The City presently receives 960 million litres of water per day from T K Halli and T G Halli reservoirs.  The completion of this project is expected to augment water supply to the City by 500 million litres per day.

Contracts have also been awarded to three different agencies to lay mild steel transmission pipelines from T K Halli to Gubbali, he said.

Contracts have also been awarded to construct reservoirs that will come up at Koodlu, Vadrapalya, Jumbo Savari Gudda, B Narayanapura, OMBR Layout, GKVK campus and Hoodi. Gammon India, Nagarajuna Constructions and IVRCL will construct them, he added.

Bangalore Water Supply and Sewerage Board shelves Drinking water from sewage project

BANGALORE: Bangalore Water Supply and Sewerage Board (BWSSB) has shelved its ambitious project to supply recycled sewage water for drinking purposes fearing public wrath, said a BWWSB official who did not want to be named.

The officials said: “People were against drinking purified sewage water.

Now, we will be supplying the tertiary treated sewage water for gardening and washing purposes to some areas through separate pipelines.” The first phase of the project was supposed to be completed by 2011 and was expected to provide BWSSB an additional 135 MLD (Million litres daily) of water to be supplied to the city.

In January 2008, the BWSSB had planned to start a project to recycle sewage and supply it for potable purpose. The project was expected to cost Rs 472 crore, and was to be jointly funded by the Jawaharlal Nehru National Urban Renewal Mission and the state government, which was taking a loan from the Japan Bank of International Cooperation.

According to the plan the sewage was supposed to be pumped to Tavarekere in Magadi Road after tertiary treatment at Vrishabavathi Valley. The water would then pass through an purification plant in Tavarekere and flow to Thippagondanahalli Tank. It would then become tha part of the city’s water supply.

According to BWSSB’s calculations, Bangalore would need around 2,200 MLD of water by 2025. At present, BWSSB supplies around 970 MLD of water through all its available resources.

BWSSB will get an additional supply of 500 MLD after the completion of Cauvery IV Phase II Stage in 2012. The BWSSB was looking to generate more than 700 MLD of water through the sewage purification project. Now, it has the onerous task of finding water elsewhere, as the water allocated to the city by the Cauvery tribunal would be completely used with the completion the Cauvery IV Phase II Stage.

Bangalore: BWSSB plans water supply for 110 new villages

BANGALORE: The Bangalore Water Supply and Sewerage Board (BWSSB) is preparing a Detailed Project Report (DPR) to provide drinking water and sanitary facilities to the 110 villages that were recently added to the city. With this, BWSSB also faces the daunting challenge of managing its limited available drinking water resources.

Though the combined area of these villages is 224 sq kms, it is scattered across different parts of the city in different proportions. This entails BWSSB to study the topography of each of the villages and make a separate plan for each of them. Unless the government approves the DPR, the plans to generate funds to provide the aforesaid facilities to the villages cannot be executed.

The sewage flows out of the city only through Vrishabavathi Valley, Koramangala Valley, Challaghata Valley and Hebbal Valley. Therefore, underground drainage (UGD) flow from these areas has to be directed to the nearest valley. Some of the connecting tunnels, especially towards the northern and eastern parts of the city, are already flowing to their full capacity and are not in a position to hold extra load. It is also practically impossible to lay new UGD lines to connect these villages to the drainage valleys.

BWSSB is planning to supply water from the Cauvery to these areas in 2012 after the completion of Cauvery IV Stage, II Phase, as it will then get an additional supply to 500 million litres per day (MLD) of water. At present, BWSSB needs another 200 MLD of water to meet the needs of the core city. With the remaining 300 MLD, it is impossible to meet the needs of the newly-added areas. BWSSB is also supposed to show source of water in the DPR.

A BWSSB official said, “We have already started to prepare the DPR and it is a challenging task. It will take some time for the report to be completed.”

Bangalore: Saving water in small measures

BANGALORE: Bangalore is taking small steps to meet water shortage. With rainwater harvesting becoming mandatory, a few more small measures are being taken. Three ground level reservoirs (GLR) were inaugurated on Wednesday. This was part of 10 GLRs planned in the city by 2010 to meet the water needs of 1.5 lakh families.

BWSSB in-charge minister Katta Subramanya Naidu inaugurated a GLR in Nagarbhavi with 5 million litres (ML) capacity at Rs 324 lakh, in Dasarahalli with 9 ML at Rs 395.25 lakh and in Srigandha Kaval with 7.5 ML at Rs 431.60 lakh.

The remaining seven GLRs will be built in Govindarajapuram (9 ML), Annapurneshwarinagar (5 ML), Nandini Layout (9 ML), Byatrayanpura (9 ML), K R Puram (9 ML), Mahadevpura (9 ML) and R T Nagar (5 ML).

Naidu said the GLRs will support water supply once the Cauvery 4th stage, 2nd phase is ready. The price of non-potable water may dip by Rs 6. Currently, it costs Rs 18 per kilo litre. Fielding stations for non-potable water will also come up at 20 places.
