India - Present awareness for corrosion is very limited in water infrastructure. Corrosion risk increases in an uneconomical way when water of varied composition is handled through pipeline networks with assets bearing mixed bag of materials of construction.

We come across numerous incidents of drinking water contamination with sewer system due to corrosion induced pipeline leakages. These pipelines have been laid very close to sewer transportation.


Contamination proliferates when the source water with contaminants is transported through water distribution system that uses a variety of unproven materials of construction.  We come across numerous incidents of drinking water contamination with sewer system due to corrosion induced pipeline leakages. These pipelines have been laid very close to sewer transportation. Our water supply concept significantly changed from the consumer owned water source to the collection and distribution managed by centralized water supply systems. Corrosion risk increases in an uneconomical way when water of varied composition is handled through pipeline networks with assets bearing mixed bag of materials of construction.  The present awareness for corrosion is very limited in water infrastructure. We need to turn Water Rust to Water TRUST to minimize corrosion induced pipeline leakages and conserve our present water resources.

Our national water policy should include norms for selecting suitable materials of construction and implementing corrosion control activities. Present water quality monitoring is not adequate to capture corrosive situations.


India - Contaminated tap water supplied to DLF Layout in Bangalore

Contaminated tap water supplied to DLF Layout. While the Bangalore Water Supply and Sewerage Board (BWSSB) has hiked the water tariff, many Bangloreans are crying foul over quality of water being supplied by the water board.


Bangalore, Nov 4, 2014, DHNS:

While the Bangalore Water Supply and Sewerage Board (BWSSB) has hiked the water tariff, many Bangloreans are crying foul over quality of water being supplied by the water board. For instance, the residents of DFL Layout, Srinivagilu at Koramangala are getting muddy water in their taps since August this year. Their memorandums to the BWSSB engineers has not yielded them any results so far.

M Krishnan, an affected resident, said “We suspected leakage in both drinking water pipeline and drainage line, and hence called the BWSSB officers to inspect the place. However, they maintained that there was no leakage and the problem remains unsolved. The Royale Paras Mark apartments, Aishwarya apartments and Shantidhama apartments in the locality are the worst affected.”

Residents rued that they spend Rs 600 every alternate day on private water tankers. Another resident, Suresh Babu, said that they also gave  samples of the contaminated water to the engineers but they remained adamant and apathetic. “They are not able to find out what the problem is. Why should we pay more when they are unable to provide proper service?,” added Babu.

Murali Krishna from Rajarajeshwari Nagar had to run from pillar to post for more than a month to get the meter at his home repaired. He said that the BWSSB engineers, whom he approached, were not cooperative and did not respond to his complaint. Similarly, Mahadevan, a resident from Mangammanapalya in Bommanahalli said that the BWSSB charged Rs 85,000 to repair the faulty meter at his apartment.

"The BWSSB said that the common meter at the apartment served so many flats and hence the cost would be high. The actual cost for repairing the meter is Rs 15,000," added Mahadevan. Meanwhile, the residents of Nagarbhavi II Stage, Link Road near Kodihalli, NR Layout in Murugeshpalya among others have complained about irregular supply of water despite taking cauvery water connection.

Engineer-in-chief T Venkataraju told Deccan Herald that he had not received any complaints from the residents of the DFL Layout regarding contaminated water. He added: "I will direct the engineers concerned to take action and respond to the people’s problems in their respective localities.

India - There is no suitable corrosion management and maintenance policy available to resolve corrosion growth and associated contamination issues reported for old water distribution

Our country is yet to find a corrosion management and maintenance policy suitable for resolving corrosion growth and associated contamination issues reported for old infrastructure. Present water quality monitoring does not cover the corrosion and material degradation concerns. Our water policy needs to be greatly modified to include these issues.

India - Water main burst near Reay Road railway station - Water supply to several areas in south Mumbai was affected

Integrity of century-old pipeline affected water supply to areas between Dadar and south Mumbai. The pipe burst has also badly damaged the road, only one lane was open for traffic on Sunday as the rest of the stretch was excavated.
