CAPpings- India - Water Conservation - Suez Wins Contracts to Curb Water Pipeline Leaks in Bangalore and Pune

Water contract awarded to curb unaccounted-for-water losses in Bangalore, the high-tech city to 16 percent from 42 percent over the next five to eight years and pipeline leaks in Pune. India is spending 589 billion rupees ($9.6 billion) to improve area water supplies and treatment systems, according to the government.

Suez Wins Water Contracts in India Cities to Curb Leaks

Suez Environnement (SEV), Europe’s second-biggest water company, won contracts to improve supplies and reduce leak losses in southern and western India.

Suez and Indian partner SPML Infra Ltd. (SPML) will help cut water leaks across a 26.5 square kilometer (10.2 square mile) area of Bangalore, the utility said today in an e-mail. It’s planning infrastructure works to curb unaccounted-for-water losses in the high-tech city to 16 percent from 42 percent over the next five to eight years, the French company said.

The utility was also awarded a contract in Pimpri-Chinchwad near Pune in western India to detect and repair leaks in area water-distribution systems. The contracts are worth 20 million euros ($27.5 million), Suez said.

“India is one of the priority countries in emerging markets and we plan to bid for more city-based water projects in the future,”

CAPpings - India - Acidic gas release from drainage pollutes environment and also corrodes components of air conditioners, refrigerators and television - Corrosion threat for public in South Delhi

Apart from the environmental damage, the drains are giving NCR residents another reason to complain. Gases emitted by the drains corrode pipes in air-conditioners, refrigerators and television, making gas leaks a frequent problem. Those who live near the drains are forced to spend thousands of rupees every year for refilling the gas. 

A drain on the pocket, every which way

Whether you are in South Delhi’s posh Defence Colony, in a DDA colony abutting the Barapullah drain, one of the many colonies lining the Najafgarh drain or in Noida’s buzzing Sector 18, you can’t avoid the foul smell emanating from open drains carrying sewage. The uncovered drains not only stink, they also endanger public health and the environment. And with roughly 50 per cent of all drains being uncovered, the problem is huge.

But this was not always the case, according to Manoj Misra of non-government organisation Yamuna Jiye Abhiyaan. “These drains were the original tributaries of the Yamuna. They were a part of the natural drainage system of the city. The open drains were never meant to carry waste water, but rapid expansion and inadequate planning made improvised sewers out of them.”

Apart from the environmental damage, the drains are giving NCR residents another reason to complain. Gases emitted by the drains corrode pipes in air-conditioners, refrigerators and television, making gas leaks a frequent problem. Those who live near the drains are forced to spend thousands of rupees every year for refilling the gas.

Rohit Dhawan, an Indian Institute of Technology-Delhi qualified electrical engineer who lives next to the Defence Colony nallah, noted: “When organic matter decays, it lets off gases. These are methane and sulphur dioxide, which have a rotten egg smell. Sulphur dioxide forms sulphuric acid when it comes in contact with water or moisture. It is this sulphuric acid that corrodes the copper in ACs and TVs.” Mr. Dhawan further explained: “ACs have copper pipes in the cooling section through which the coolant passes. The sulphuric acid corrodes these pipes. It can be observed as the black covering on the cooling pipes. Similarly, all the circuits in electronic equipment are of copper. These get corroded and lead to malfunctions.”

Pooja Chandok, a resident of Sector 40 in Noida, said it was only when her family moved to Noida, where she lives close to a large open drain, that she became aware of the problem. “We had lived in other parts of Delhi, but never had to refill the gas in our ACs every year until we came to Noida. Every year, we have to spend about Rs.10,000 on getting gas filled — it costs around Rs.2,000 per AC.”

Uday Kumar, an electrical repairman in Noida, said the average life-span for a gas refill is three months. The intensity of the gases emitted by the drains makes a brand new copper pipe show signs of corrosion within a month. But he is not complaining, for it gets him work. On the other hand, Meenakshi Oberoi, a resident of Noida Sector 25, is fed up with her recurring expenditure on air-conditioner upkeep. The large open drain behind her house means the ACs in her house need gas refills every other year. But she has made a deft move and “switched to non-branded ones because they work a little better in Noida”.

With increasing competition, residents have discovered that white-goods manufacturers had, in order to cut prices, compromised on quality too. “In the last 10 years, many manufacturers started using thinner cooling pipes. This has resulted in their faster corrosion. Corrosion will occur, but the period between breakdowns/leakages can be increased by using thicker pipes in the ACs,” explained Mr. Dhawan.

As if the gas leaks weren’t bad enough, residents living in the vicinity of open drains are also having trouble in getting annual maintenance contracts (AMCs) for them.

A resident of Ambika Vihar in West Delhi, Anil Ahluwalia, said: “One authorised service franchisee did not give me an AMC for my AC for nearly three years. The reason given was that my house was near the Najafgarh drain and hence my AC was more prone to defects such as gas leaks.”

Mr. Ahluwalia said he has to pay the service centre visiting charges as well as bear other expenses without an AMC. “It costs me more as I need to get the gas filled twice a year. However, my relatives living in a colony nearby don’t face any such problem as their home is away from the drain.”

Meanwhile, Sameer Bhandari of utility services said a franchisee cannot refuse to do an AMC. “We might charge extra in the Vikaspuri belt, which includes areas of Paschim Vihar and Vikaspuri near the drain, including Ambika Vihar. If the AMC for a one-and-half tonne window AC costs Rs. 2,000 plus taxes in other areas, in these areas it would be R. 3,000 plus taxes. This includes any spare parts plus gas.”

Agreeing, Ms. Chandok said AMCs in Noida are more expensive than other areas due to the frequent gas leaks. “One company had started a five-year AMC scheme, so many of us bought their product. But they soon realised that this was not cost-effective and discontinued the scheme.”


Dealing with the nallahs of the National Capital Region, as even AC manufacturers have realised, is a losing proposition.

CAPpings- India - Water Pipeline Leakage - Another pipe burst; supply disrupted in Thiruvananthapuram - Corrosion is identified as the major cause

The bursts on the 1,200-mm transmission main have been a regular feature, with the 15-year-old pipeline being weak and corroded at several points. Work on a Rs.50 crore-project to replace the pipeline, from Aruvikkara to Peroorkada with mild steel pipes, is dragging on. Officials said it would take at least another month to complete the project.

Another pipe burst; supply disrupted in Thiruvananthapuram

The pre-stressed concrete (PSC) transmission mainline carrying water from Aruvikkara to the Observatory Hills tank, known for numerous bursts in the recent past, lived up to its notorious record with a major burst on Tuesday.

The burst, noticed around 4 p.m. near the Karakulam bridge on the Thiruvananthapuram-Shencottah road, is likely to disrupt water supply at several places in the heart of the city and towards the western parts till Wednesday evening.

Kerala Water Authority (KWA) officials said the burst occurred in a portion of the 1,200-mm mainline that narrowed down to 1,000 mm at the particular point. Excavation work was on to remove the mud over the pipeline and ascertain how big the leak or burst was. This would take several hours. A mild steel pipe piece would have to be lowered into the trench and welded on to the existing pipe at both ends to replace the affected portion. Repairs would take up to 24 hours. Normal water supply to the affected areas was likely to be restored only towards Wednesday evening, they said.

India - Railways - Corrosion Control efforts - ICF Steel beauty goes to Mumbai - Country’s first stainless steel Electric Multiple Unit coaches, designed and manufactured by the Integral Coach Factory (ICF)


Stainless steel minimise corrosion maintenance. Integral Coach Factory  will completely switchover to stainless steel coaches in four years.



Country’s first stainless steel Electric Multiple Unit coaches, designed and manufactured by the Integral Coach Factory (ICF) for  Mumbai Urban Transport Project (MUTP), was flagged off from the ICF, here on Tuesday.

The first prototype of 12-car rake that was flagged off on Tuesday was manufactured under the phase two of MUTP. ICF bids to supply a total of 72 car rakes to Mumbai Railway Vikas Corporation (MVRC), which is executing the Rs 3,000 crore project.

The stainless steel EMUs have been manufactured by the Integral Coach Factory  operates on alternate current traction using the state-of-the-art IGBT technology based on three-phase propulsion system. The first of its kind technology in the country is supplied by German-based Bombardier Transportation.

According to officials, the stainless steel coaches having straight sidewall design, developed on Linke Hoffman Busch (LHB) platform, as against the regular bell-shaped coaches in India would make trains run faster.

The coaches are more spacious and have force air ventilation system mounted on roofs to avoid entry of water. The coaches have wider windows, improved interiors, better aerodynamics, rugged user-friendly locks and latches which are eco-friendly, thereby reducing consumption of carbon and fossil fuels and emissions, the officials added.

The EMUs made using IGBT technology are 30 per cent more energy efficient than normal EMUs, including those supplied under Phase-I of the project. These units would help Mumbai suburban services save around `100 crore per year.

Rakesh Saksena, chairman and managing director of MRVC, said, “Around 7.5 million commuters use suburban trains everyday in Mumbai. Phase-I has already brought down overcrowding to an extent and phase-II would further reduce it.”

According to Pankaj Kumar, chief mechanical engineer, “Stainless steel minimise corrosion maintenance. Integral Coach Factory  will completely switchover to stainless steel coaches in four years. The second prototype rake would be ready before the end of October.”

US - Automotive Industry - Priority for effective corrosion resistance is felt in the new truck design - 2014 Silverado Most Rust-Resistant Chevrolet Truck Yet, GM Says


Maintenance of Truck is the key for improving the corrosion resistance and extending the life of truck




2014 Silverado Most Rust-Resistant Chevrolet Truck Yet, GM Says

New truck design starts with zinc-coated (galvanized) steel for the roof and all body panels except the hood, which is made of an aluminum alloy that reduces weight and provides corrosion resistance.

DETROIT – More than half of light-duty pick-up trucks on the road are now 11 years or older. To help build on the Chevrolet Silverado’s reputation as the most dependable, longest lasting full-size pickup, engineers designed the 2014 Silverado to be the most corrosion resistant Chevrolet truck ever.

The 2014 Silverado starts with zinc-coated (galvanized) steel for the roof and all body panels except the hood, which is made of an aluminum alloy that reduces weight and provides corrosion resistance. At every step of the design and manufacture of the new Silverado, materials and production processes were selected to help minimize deterioration over time.

“Silverado’s corrosion protection measures provide superior defense against elements in the environment, whether driving through farm fields, on construction gravel, or down a snow-covered highway,” said Mark Yergin, engineering group manager, General Motors Corrosion Engineering and Labs. “The new Silverado is our strongest truck yet, affording us the confidence that the truck will continue to meet customers’ needs throughout its life.”

Additional 2014 improvements over previous models include:

¦All new body structures designed to minimize the potential for corrosion.
¦Improved hem flange sealing on the doors and hood, and additional underbody flange sealing help keep the joints of the truck dry, discouraging deterioration that might occur from moisture
¦Extensive and improved chassis corrosion protection that enhances the truck’s appearance and lengthens the life of underbody components
¦Anti-chip protection on the lower body side for extra protection from stones or gravel.

The effectiveness of these changes was borne out during extensive proving ground testing at exposure levels higher than most drivers ever experience. The months of accelerated testing these trucks undergo is equivalent to more than 10 years on the road.

Post-test evaluations of the trucks, including the search for and elimination of corrosion even on areas of parts customers never see, helps ensure the overall vehicle performance.

CAPpings - India - Water Leakage - Leak in pipeline briefly disrupts water supply in Coimbatore - Timely response restored the supply

Water supply from Pillur I project was temporarily affected after a leak was detected in the main supply line near Karattumedu near Saravanampatti. Timely response of water management authorities restored the supply



COIMBATORE: Water supply from Pillur I project was temporarily affected after a leak was detected in the main supply line near Karattumedu near Saravanampatti. The TWAD board officials were informed and they rushed to the spot and carried out maintenance work. Water supply was restored by Thursday evening.

"We have carried out maintenance work and the leak has been closed. The supply was completely restored by 5.30 pm," said Iqbal, executive engineer, Tamil Nadu Water Supply and Drainage Board (TWAD).

Residents found water gushing out of the main supply line which is connected to the master reservoir at Ganapathy from where water is supplied to corporation wards.

"The TWAD maintenance team was notified and they started maintenance work at the identified spot. Water supply has been completely restored in city limits," said a senior corporation official.

The supply to eastern parts of the city is dependant on Pillur water and was temporarily affected after the valve was closed to carry out maintenance on the damaged pipeline.

CAPpings - India - Water Leakage - Pipeline leak inundates colony in Iyyappanhangal, Chennai - Valve Failure and Pipeline Damage are identified as the causes

Pipeline leak inundates colony in Iyyappanhangal, Chennai - Valve Failure and Pipeline Damage are identified as the causes.  Water seeped into the settlements at EVP Park Avenue in Iyyappanhangal after a valve in a pipeline carrying drinking water from Chembarabakkam lake to Chennai burst early morning on Saturday


Water seeped into the settlements at EVP Park Avenue in Iyyappanhangal after a valve in a pipeline carrying drinking water from Chembarabakkam lake to Chennai burst early morning on Saturday

Residents of Iyyappanthangal on the outskirts of Chennai woke up to knee-deep water outside their houses on Saturday morning after the valve on a major pipeline carrying drinking water to the city from the Chembarambakkam lake allegedly gave way.

The flooding resulted in a complete blackout in the area as the Electricity Board disconnected power supply to ensure safety. Power was restored after over eight hours when a considerable amount of water was pumped out by the evening.

Residents said within a matter of an hour, the streets in the colony were filled with at least 3 feet of water. The water made its way into several households, forcing the residents to stay indoors till evening when three motor pumps drained out a fair bit of the stagnated water.

A senior official at the Chennai Metro Water told Express there was no “burst” as claimed by the residents and it was only a leak in a major pipeline as a valve gave way.

The official said almost immediately after the leak was reported, the supply at Chembarambakkam pumping station was stopped. “What came on to the streets was water already in the pipeline that ran several kilometres. The leak has now been plugged,” the official added.

CAPpings - India - Water Leakage - Improper interconnection design followed by contractor and no vigilance on pipe laying work are leading the way for leakage - Residents protest as water woes continue in Kerala


Improper interconnection design followed by contractor and no vigilance on pipe laying work are leading the way for leakage


Residents protest as water woes continue

Though Kerala Water Authority (KWA) has claimed that the new  pipeline from SN Junction to Puthiyakavu was laid to resolve the water scarcity in Tripunithura, it proves otherwise in some areas.

The residents at Thekkumbhagam said they have been facing acute shortage of potable water for the past two months.

While KWA authorities blame the leakage at spots where the pipes interconnect, the technical committee members of Tripunithura Rajanagari Union of Residents Association (TRURA) say the KWA has not ensured perfection in pipe-laying work.

“The KWA has not monitored the pipe-laying work and they allowed the contractor to conduct the interconnections by himself. As a result, there are leakages at some spots and there is a chance that it might get worse,” they said.

An automaker was recalling about 370,000 vehicles in North America due to possible corrosion of the steering shaft that could cause a loss of steering



Ford recalls 370,000 vehicles in US, Canada due to steering risk

NEW YORK, AUG 31:
Ford Motor Co said it was recalling about 370,000 vehicles in North America due to possible corrosion of the steering shaft that could cause a loss of steering. The recall, affecting the 2005-2011 model years of the Ford Crown Victoria, Mercury Grand Marquis and Lincoln Town Car vehicles, will take place in high-corrosion US states and Canadian provinces, Ford said in a statement.

About 355,000 of the recalled cars are located in the US and some 15,000 in Canada. The vehicles are affected by de-icing chemicals used on roads during winter months. Ford said it would replace the lower intermediate steering shaft and, if necessary, replace the upper intermediate steering shaft.

The corrosion problem “may potentially result in loss of steering,” the US automaker said. “We are not aware of any accidents or injuries attributed to this condition,” it said.

Ford said any customers who have concerns regarding their vehicles’ steering would also be able to have their vehicles inspected and repaired if necessary.

India - Water Contamination - Nearly 70 percent of diseases in Hyderabad are water-borne. The city seems to be reeling under water contamination.


Pause a second before you have water. Nearly 70 percent of diseases in Hyderabad are water-borne



Believe it or not, nearly 70 percent of diseases in Hyderabad are water-borne, according to a survey conducted by Eureka Forbes and GFK Water Audit 2013. The city seems to be reeling under water contamination. To understand its impact and key issues with drinking water in Hyderabad and other parts of the country, Eureka Forbes and GFK conducted a nationwide survey titled “Kya Aapka Paani Beemar Hai.”

In all, 325 households were interviewed in Hyderabad as part of the survey. The findings revealed some hard-hitting facts. Ground water samples collected and examined by the Eureka Forbes Institute of Environment, a non-profit organisation, revealed that levels of Total Dissolved Solids (TDS), Hardness, Chlorides, Nitrates, etc responsible for water contamination have exceeded permissible limits in certain parts of Hyderabad such as Madhapur, Asif Nagar, Secunderabad, Abids and Pragathi Nagar among other places.

Toxic chemicals such as arsenic and lead and disease-causing bacteria are also contributing to the alarming increase in water contamination. Five out of every 10 respondents surveyed had someone in family and friends falling sick in the last one year due to water contamination.

Incidence of water-borne diseases like cholera, jaundice, typhoid, diarrhoea, common cold, cough and fever is higher amongst the people when compared to malaria, dengue and other diseases.

About 48 percent respondents attributed diseases in their families to contaminated water. Almost 50 percent respondents said their drinking water is unfit for consumption.

India - CAPpings - Water contamination leading to food poisoning cases in Kozhikode, Kerala: Pipelines are 40 years old and rusted


The pipelines that supply water to various institutions on the campus are around 40 years old and mostly rusted. They leak at various places, giving rise to the possibility of dirt entering them through the cracks.

On Wednesday, 30 people, including B.Sc. Nursing students of the College of Nursing on the Government Medical College Hospital campus here and some staff members, were admitted to the hospital owing to food poisoning. The hostel and the mess were closed down for two weeks after the incident. Two days later, 15 persons, some of them M.Sc. Nursing students and the others members of the staff, took ill after having food from the staff mess and the Indian Coffee House.
The reasons for the recurring cases of food poisoning reported from the mess facilities on the college campus are unclear.
Food Safety Officer Anil Kumar told The Hindu that water supplied from a common tank to all the hostels and hospitals in the region could be the source of infection. A team of the Food Safety Authority, which included Mr. Anil Kumar, had visited the campus and collected samples of food and water. These had been sent to the Regional Analytical Laboratory for investigation, and the results were expected on Monday.
The water supply system is also under the scanner. The pipelines that supply water to various institutions on the campus are around 40 years old and mostly rusted. They leak at various places, giving rise to the possibility of dirt entering them through the cracks.
The drains near the hostels are clogged with garbage and dirty water, and pose a threat to the health of the students. The authorities are turning a blind eye to the students’ safety, they allege.

UK - Health Sector - Corrosion halts opening of the new £150m critical care unit at the Royal Victoria Hospital in Belfast, Northern Ireland

Pipework problems delay £150m critical care hospital unit in Belfast, UK. Corrosion has been found in the building's new heating system.


The opening of the the new £150m critical care unit at the Royal Victoria Hospital in Belfast is to be delayed further because of a problem with the pipework.

Corrosion has been found in the building's new heating system. It means a major repair job has to be completed before it can open to patients.The delay will be longer than first thought, as workers are employed trying to fix the plumbing problem.

It is understood the damage to the pipes was detected in the hot water heating system during final checks.The main emergency department for Belfast, and intensive care for patients across Northern Ireland, will fill the first six floors. The top three floors will eventually house maternity services.

Control
The new 12-storey building was due to be handed over to the Belfast Health Trust in November 2012, but that deadline was missed.The Department of Health has confirmed the trust will not take control of the building until 2014 at the earliest.

"Significant delays in the completion of this project have been due to problems with corrosion in the closed water systems identified in the commissioning process," it said. "Handover of the completed fully commissioned building is now expected in 2014."

Once the trust does take ownership of the new state-of-the-art building, it is thought it will be another three months before it is ready to admit patients. UNISON health trade union spokesman Ray Rafferty, who is based at the Royal, said his main concern was "that the building is going to be delayed by 12 to 14 months".

"That means services are delayed, and patients are going to suffer because of these delays," he added.

India - Kerala - Water Authority spends Rs 2.5L, repairs pipeline at Kathrikadavu- proposal for replacing old concrete primo pipes with Ductile Iron pipes still remains on paper

Though there is a proposal for replacing the old concrete primo pipes with DI (ductile iron) pipes, it still remains on paper. There are allegations that authorities won't act unless a small leak becomes large enough for their contractors to take up the work. Contractors find small leak work unprofitable.

KOCHI: Spending around Rs 2.5 lakh Kerala Water Authority (KWA) on Saturday restored water supply to several parts of the city that was disrupted after a pipe burst on Friday near Kathrikadavu.
According to KWA officials, they completed the repair work and restored the water supply by 9am.
While Rs 1.75 lakh had to be given to contractors, the cost of material and compensation for damage to nearby property came to Rs 50,000 and Rs 30,000 respectively. "To hold the pipe, we had to buy two drum collars from Steel Industries Kerala Limited  that cost Rs 25,000 each. The charges of contractors came to about Rs 1. 75 lakh,'' a KWA official said.
For the pipe burst in April, the agency had spent almost the same amount for repair works and compensation. KWA officials attribute the frequent pipe bursts to the use of outdated pipes.
Though there is a proposal for replacing the old concrete primo pipes with DI (ductile iron) pipes, it still remains on paper. "We had brought the issue to the attention of those concerned. But none of them, including local body members, took action," said Ernakulam District Residents Associations' Apex Council president R Lohithakshan.
"Even two weeks ahead of the pipe burst in April, we had informed KWA officials about a leak developing in the pipeline. But they did not pay heed to our call. There are allegations that KWA won't act unless a small leak becomes large enough for their contractors to take up the work. Contractors find small leak work unprofitable,'' he said.

India - Railways - Corroded portion of rail track replaced near Chromepet railway station, Chennai

Timely response of Railway staff has averted catastrophic failures. There should be a structured vigilance on rail tracks near coastal zones. The corrosion was probably caused by the discharge of sewage on to the tracks from toilets, they said.

Southern Railway staff replaced a slightly fractured, highly corroded portion of a railway track on the main line near Chromepet railway station on Monday afternoon.

Officials at Southern Railway said an employee noticed a minor fracture on the track on the main line (Egmore to Chengalpattu) a little past 1.30 p.m. A team of staff members and contract labourers sawed off the corroded track close to the railway level crossing (LC No. 26) and replaced it with a new piece of track for a length of 10 metres.

 The new track was subsequently welded. Except for the diversion of Pallavan Express on to a parallel main line, the repair work caused no disruption to rail traffic, officials said.

Staff said they suspected the minor fracture had been caused after the passing of Vaigai Express around 1.30 p.m. or even earlier in the day after the movement of other long-distance or freight trains. The fracture apart, it was the corrosion, for a length of 6 metres that had worried them. The corrosion was probably caused by the discharge of sewage on to the tracks from toilets, they said.

CAPpings - India - Mangalore - Water leakage of 25% triggered Rs 107.16 crore water supply project - Replacement of 30 year old Cast Iron Pipe with HDPE due to corrosion

Leakages plague water supply system in Mangalore


The water wastage due to leakages is estimated at 25%, according to the city corporation engineers, whereas the accepted standard is below 15%. This increased leakage is due to the new pipeline being linked to the old and outdated pipelines.

MANGALORE: The Rs 107.16 crore water supply project, conceived under KUDCEMP and executed by the Karnataka Urban Infrastructure Development and Finance Corporation, has definitely increased water supply to the city, but at the same time it has increased water wastage due to leakage.
This project too has seen delays and cost overruns. It was a Rs 135 crore project which was scaled down to Rs 98 crore removing some components. When it finally got completed, the cost was Rs 107.16 crore.
Water leakage is one of the issues that put brakes on the Mangalore City Corporation's plans of providing uninterrupted water supply. The total estimated cost of the 24X7 project was pegged at Rs 138 crore two years back.
This increased leakage is due to the new KUDCEMP (Karnataka Urban Infrastructure Development and Environment Management Project) pipeline being linked to the old and outdated pipelines, which are serving the city beyond their rated years. The water wastage due to leakages is estimated at 25%, according to the city corporation engineers, whereas the accepted standard is below 15%.
The water pipelines, mainly 18 inch cast iron in Mangalore city, were laid way back in 1958. The life was 30 years, which means that the pipes have been serving the city even after their estimated `life'. Whereas the new lines are of durable HDPE.

India - Agriculture - Corrosion of Barrage Shutters, a big concern for farmers in Cauvery Delta Districts, Tamilnadu. Waste water released into the Cauvery has worsen the situation

Corrosion of Barrage Shutters, a big concern for farmers in Cauvery Delta Districts, Tamilnadu. Waste water released by the dying units into the Cauvery worsen the situation.


TRICHY: Farmers in delta districts are disappointed over the dry-Cauvery river. But the dryness has helped the public works department (PWD) to take up refurbishing rehabilitation works on corroded shutters of the barrage at Upper Anaicut (Mukkombu) in Trichy. The waste water containing chemicals released from dying units in Karur to the river is said to be one of the major reasons for corrosion.

The second phase of refurbishing works on 26 of the total 41 shutters on the barrage began in February this year. The work is taken up with a Rs 4.5 crore loan from National Bank for Agriculture and Rural Development (NABARD).

The barrage had been constructed in Mukkombu, where the River Kollidam branches out from Cauvery river, to store excess water for irrigation in 1977. Since then, no repair works were conducted. A PWD official said, "Though, there are many reasons, including the years, for corrosion of the shutters, the waste water released from the dying units in Karur district into the Cauvery river has worsens the condition of the shutters wreaked havoc to the shutters. Such chemical water corroded the bottom portion of the shutters in the long run. Hence, water-leakage takes place."

India - Water Contamination due to Corrosion - 60% rise in complaints of leaks in water pipelines, Kurla worst-hit


Water contamination due to corrosion of pipelines in Kurla, Mumbai




60% rise in complaints of leaks in water pipelines, Kurla worst-hit

At a time when the state is facing its worst drought in decades, precious litres of water are being wasted every day owing to leakages in the city's pipelines, which have risen by a whopping 61% since last year. Experts said that old, ill-maintained pipelines and a flawed distribution network are to blame. What's also worrying is that leakage contributes to contamination of water in the long run.

"The distribution system is flawed. Besides leakages in the century-old pipelines in the island city, the absence of a monitoring mechanism leads to wastage of more than 25% water every day," said former deputy municipal commissioner Prakash Sanglikar. "This could lead to contamination and affect public health."

Asserting that leakages in the corroding, old pipelines are a big reason for water contamination, experts demanded immediate action. "The BMC must take note of deteriorating pipelines, which have an alarming effect on the supply system and on health," said Nitai Mehta, founder-trustee, Praja Foundation.

CAPpings - India - Corrosion induced Oil Pipeline Leak in Tiruvottiyur blows lid off two-year-old problem of CPCL pipeline in Chennai. Residents are affected

CPCL asserts facility is in good health. Residents say “The discharge of oil has intensified over the past two years.

Industries in India do not have specific department in their setup or do not engage specialist people during the design stage to have a proper corrosion management program. Corrosion control activities are presently attended by other functional groups.

Residents have been complaining of seepages from the CPCL pipeline; oil company asserts facility is in good health
A leak in an underground oil pipeline in Tiruvottiyur on Friday set off panic among residents even as oil company officials initiated immediate action to plug the hole and clear the contaminated soil on Ottravadai Street. While CPCL officials said that the pipeline was being monitored regularly and no abnormality had been detected, TNPCB officials, who inspected the spot, said the leak was due to corrosion.

Residents said the leak was first been noticed at 6.30 a.m. By 8 a.m., the area was cordoned off by Chennai Petroleum Corporation Limited (CPCL) with the assistance of the fire service personnel and Central Industrial Security Force. Soon, the excavation of the area began and the workers kept throwing mud on the oil collected in the pit dug up to plug the leak on Ottravadai Street. Chennai Corporation Councillor Prabhakaran said the residents have been complaining about the oil leak for the past few months. Many wells and bore wells in the residential locality have been closed because of oil contamination. CPCL officials said the leak had been plugged by evening.

As a school was located on the same street where the leak occurred, officials asked residents to avoid cooking or using LPG stove for any other purpose till the hole was plugged. “The discharge of oil has intensified over the past two years. Luckily today, no vehicles skidded on the oil patch,” said S.Damodaran, a resident.

The 30-inch oil pipeline runs for a distance of 6.9 km underground and 300 metre above ground level. “The pipeline has been properly assessed for its health periodically. CPCL has been taking extraordinary precautions to periodically inspect the health of the pipeline. The pipeline is protected by impressed current cathodic protection system and monitored every week. Walk-through inspections of the pipeline are done every fortnight. Extensive condition assessment studies of the pipeline are done once in four years and the last exercise was done by Engineers India Limited (EIL) in December in 2012,” a CPCL release said.

CAPpings - India - Water Conservation - Government plans to ask big industries for 'water returns'


We, Corrosion Control Community, hope for introduction of Material Returns and Corrosion Prevention Act in future to conserve material resources in India





India - Water Conservation - Government plans to ask big industries for 'water returns' 

Seeking to curb the unbridled use of water and check pollution, the government is considering to introduce a system under which the big industries will have to file 'water returns' on the lines of income tax returns. Besides, the government is also mulling introduction of differential rate of pricing of water by different types of industrial users.

The annual water returns on similar lines of tax returns would include key parameters like utilisation per unit produce, effluent discharge details, rain water harvested, water reuse details and fresh water consumption, said the 12th Five Year Plan (2012-17). The document, which has been approved by the country's apex decision making body the National Development Council(NDC) and is broad policy for the five-year period, has emphasised that the filing of water returns be made mandatory for big industries and businesses.

The policy document has also underlined the need for promoting reuse and recycle of waste water in industry through regulations and incentives through national frameworks and a system of water returns. It also talks about setting industry-specific standards for promoting rain-water harvesting in industry, both within and beyond the fence through incentives and regulation. The policy also asks for creating equity-based and efficiency-based water pricing regime for industries. It also asks for overcoming lack of a clear policy framework based on cost-recovery principles.

According to the document, the current pricing regime is undervalued for all users and creating a clear policy framework would overcome wide variations in tariff structure due to current determination by various states.
