High water table, clogged sewers pose threat to buildings: Walia

Special Correspondent

NEW DELHI: A clogged sewerage system and a massive rise in the water table from a depth of about 40 to 50 feet to a mere four to five feet are now posing a major threat to buildings in several parts of East Delhi, Urban Development and Finance Minister A.K. Walia said on Wednesday.

During a visit to several parts of his Laxmi Nagar constituency, the Minister stressed the need to repair urgently the collapsed sewerage system and reduce the water levels by removing some of the accumulated water from the Yamuna river-bed across Pushta Road.

Permanent solution

Dr. Walia, who was accompanied by senior officials from the Central Ground Water Board, Irrigation and Flood Control Department, Delhi Jal Board, Delhi Development Authority, Public Works Department and Municipal Corporation of Delhi, called for finding a permanent solution to the problem of accumulation of water at various places between the Yamuna and the Pushta Road opposite Laxmi Nagar and Ramesh Park.

He said a feasible solution was a must or else a number of colonies that have come up near Pushta Road in East Delhi will continue to face threat to the buildings due to a high water table in the area.

Pumps installed

The visit of the Minister to the Yamuna banks assumes significance in the backdrop of the recent Lalita Park building collapse that left nearly 70 people dead and had been attributed to accumulation of water in the basement due to many reasons.

During his visit to various pockets, the Minister was told by officials that the accumulated water has somewhat receded after installation of two pumps. But the officials said the level was still very high and because of it the danger of another building collapse in the area loomed large.

The Minister instructed the Irrigation and Flood Control and CGWB officials to chalk out a plan of action to reduce this water level. He said the colonies where basements are getting damaged and cracks have become visible in the buildings need to be protected. A suggestion to construct a small temporary drain to flush out the accumulated water into the Yamuna was also discussed.

Dr. Walia said he has already taken up the matter at the highest level so that a feasible solution could be found at the earliest. Dr. Walia also asked the MCD to expedite their ongoing survey and encourage people in getting their plan sanctioned before starting construction as structural stability has become crucial in the backdrop of the recent mishap.

He also admitted that he had been frequently getting complaints about failure of sewerage system and caved in roads in his constituency. Since the sewerage system is handled by Delhi Jal Board, he has often insisted that an action plan be prepared by the Board.

The Minister also visited Priyadarshini Vihar, C-Block Laxmi Nagar and Vikas Marg near Swasthya Vihar where roads have caved in at several places due to overflooding of sewerage lines.

Potable water supply plan gets ADB push

Himanshu Kumar Lall | Dehradun

To supply clean drinking water in Dehradun, a project with the support of Asian Development Bank has been started. More than 170 kilometres of new pipeline would be laid down by the department. All three nodal agencies associated directly or indirectly with the supply of potable water to the people will contribute to bring the project to the ground level.

People living in the remote areas suffer most. The pipelines to supply potable water were laid around 40-50 year ago. People also wanted the old pipelines to be replaced by the new ones, due to hygiene concerns. Despite the Government’s claim to provide round-the-clock potable water in every corner of the district, people are waiting for the supply.

Government official Raghunath said that the project is entirely funded by ADB (Asian Development Bank) for replacing old pipelines with new ones. He told that Gandhigram, Luxman Chowk, Khurbura, Sanjay Colony and Parade Ground and other adjoining areas are among the main localities of Dehradun where new pipelines will be laid down by the department. Raghunath informed that Peyjal Nigam, Municipal Corporation of Dehradun (MCD), Public Works Department (PWD) etc. government departments have been contributing to bring the project to the ground level.

“Dehradun is divided into seven zones under Uttarakhand Urban Sector Development Investment Programme (UUSDIP),” he said, adding that the project is likely to complete by 2012. Raghunath informed that the project is being undertaken by Vishwas Infrastructure and instructions have already been released to every official to bring the project to the ground level in the given time frame.

24x7 water for all

Ranesh Nair, Isher J Ahluwalia

Posted: Wednesday, Nov 24, 2010 at 0044 hrs IST
Nagpur, the ‘Orange City’ of Maharashtra and its winter capital, is delivering 24x7 water to 10% of its population. The pilot project for continuous water supply in Bajiprabhu Nagar in Dharampeth zone was conceived in 2007 and commissioned in 2009. Nagpur has joined Hubli-Dharwad, Belgaum and Gulbarga in Karnataka to provide 24x7 water to its residents.

In a long overdue exercise setting standards for service delivery for core urban services, the Ministry of Urban Development, Government of India, has recommended 24x7 water as the norm for all cities and towns of India in a report brought out in 2008. This reflects the recognition that continuous water supply is vital for both health and sanitation, and that leapfrogging in this respect is a desirable and feasible option.

For Nagpur, it all started with the Sukhantkar Committee, which was set up by the Government of Maharashtra in 2000 to review the efficiency...of water supply in the towns and cities of Maharashtra. The Committee recommended water audit for all cities of Maharashtra and the state government offered to fund 75% of the cost of studies to measure the gap between the cities’ water input and their billing for water ostensibly consumed by the consumers.

In 2003, the Nagpur Municipal Corporation (NMC) tried to augment the supply of bulk water to the city by building water treatment facilities, water mains, and elevated service reservoirs. This increased the volume of water input to the city by 32%, but sales of water showed no increase. It turned out that leakages/losses in the distribution network offset any gains from augmentation.

Nagpur was the first city to conduct the water audit, which revealed water losses to the extent of 52%. The transportation loss from the bulk source was 30%. The distribution network of approximately 2,100 km of pipes in...

the 10 zones for water distribution in Nagpur also had a massive water loss problem resulting in non-revenue water and commercial losses for the Corporation.

A number of initiatives were taken up by NMC to improve the efficiency of operations in water treatment plants via the water audit and via the upgrading of pumping stations through the energy audit, and to plug the leakages in the distribution network in the city, which has resulted in increasing Nagpur’s water system efficiency from 32% in 2005 to 41% in 2010.

NMC has put in place a series of projects to upgrade the augmentation system. Canals that carried raw water from the first source at Pench 48 km outside of the city are being replaced by pipes and the second source at Kanhan is being augmented (both under JNNURM), bringing down the cost of raw water by 75%.

Production capacity is expected to increase...

to 765 mld, which should meet the additional demand for water up to 2021. Not only does this augment Nagpur’s water supply by 235 mld with no additional burden on natural resources, but the NMC/Government was able to save about Rs 300 crore that would have been spent on developing a new water source.

A major initiative of the Corporation was the pilot 24x7 water supply project, which has attracted much attention. A performance-based management contract of the project in the demo zone was awarded to Veolia Water at a cost of Rs 27 crore (including rehabilitation). No capital investment was made by the private party for the pilot project. Of the distribution network, 70% of the assets were retained and 30% replaced. All legal connections were metered, while slum connections were not metered.

Close to 10,000 connections now have access to 24x7 water supply. Another 5,000 connections will be...

activated by December 2010. Water pressure has increased ranging from three to fivefold, as a result of which households have stopped using booster pumps, which saves energy. A customer care centre has been set up for generating bills, receiving payments and attending to complaints 24x7. Non-revenue water in the demo zone has come down from 50% to 32%.

To recover costs, tariffs had to be raised. But customers were used to paying less because of faulty meters and/or theft. Moreover, tariffs had not been raised for nine years. Also, at the time of the switchover, bills were delayed and customers received their bills for six months at one go. Communicating the need for a tariff increase was a challenge, and there seems to have been no strategy in place to do this. For example, the minimum water tariff was to increase from Rs 3 to Rs 8, and a case...

was not properly made to the customer. Timing was also bad because of the elections in May and October, 2009. Protests were organised by NGOs against the tariff increase.

Not surprisingly, the general body of the NMC decided to reduce the water tariff. The fact remains that water tariff in Nagpur is one of the lowest in the region. For example, NMC’s minimum tariff of Rs 5 per unit is much lower than the Rs 11 per unit charged by Maharashtra Jeevan Pradhikaran (MJP), the apex water supply department of the state government to areas in and around Nagpur. As NMC Commissioner Sanjeev Jaiswal put it: “The downward revision of the tariff increase was a necessity because of the opposition raised by civil society but in the years to come, the real challenge would be to increase this tariff again to make the operation economically viable.”

Despite the initial setbacks to...

raising the water tariff, NMC has launched an ambitious programme of universalising the 24x7 norm to the city. A special purpose company, Nagpur Environmental Services Ltd (NESL), was set up in 2009, wholly owned by the NMC, with a view to separate the water account from the municipal accounts and empowering the company to focus on all aspects of the development and management of the water operations for the city of Nagpur. To ensure financial sustainability, NMC has now revised the tariff structure for O&M for partial capital cost recovery. The tariff has an inbuilt provision to pass on the increase in input cost for raw water and energy directly to the consumer. NESL has used public-private partnership to address the challenges of integrated management of the water economy of Nagpur. NMC received the second prize in PPP Initiatives in the National Urban Water Awards 2009 by Ministry of Urban...
Development, Government of India, on August 13, 2009. In February 2009, the city wide 24x7 water project was approved under Jawaharlal Nehru National Urban Renewal Mission (JNNURM).

In November, 2010, NMC awarded the contract to Veolia Water (India) Pvt Ltd and Vishwaraj Environment Pvt Ltd at a price of water Rs 7.90 per thousand litre sold and received from the customer. The private operator will bring 30% of the sanctioned capital cost and any cost escalations that may arise. As Dinesh Rathi, the consultant to NMC on the project explained: �This project will provide much-needed professional approach to urban water management.�

The progress made by Nagpur in the ambitious water initiative will be followed closely by the entire nation, as success on this will have a positive demonstration effect for many other cities wanting to do the same.
