CAPpings - Water Damage, a big concern for Electronic Gadget Users: Corrosion leads to malfunction of devices like iPhone, iPod when exposed to Water or other liquids

If an electronic device like iPhone or iPod is exposed to water or other liquids, corrosion—an irreversible deterioration or degradation of materials—may result. This may cause the device to malfunction. There is no warranty for liquid damage.


If an iPhone or iPod has been damaged by liquid (for example, coffee or a soft drink), the service for such liquid damage is not covered by the Apple one (1) year limited warranty or an AppleCare Protection Plan (APP). iPhone models and iPod models that were built after 2006 have built-in Liquid Contact Indicators that will show whether the device has been in contact with water or a liquid containing water.

If a device is exposed to water or other liquids, corrosion—an irreversible deterioration or degradation of materials—may result. This may cause the device to malfunction. If a device has been or is suspected to have been exposed to water or other liquids, inspect the following areas for evidence of corrosion: the dock connector, the headset/headphone jack, the dock screws, the speaker or microphone mesh, and any exposed metal parts. 

iPhone and iPod products are equipped with Liquid Contact Indicators in the bottom of the headphone jack. iPhone 3G, iPhone 3GS, and later models also have an indicator on the bottom of the dock-connector housing. These indicators will be activated when they come in direct contact with water or a liquid containing water. They are designed not to be triggered by humidity and temperature changes that are within the product's environmental requirements described by Apple.

At the base of the headphone jack, you should see what is normally a white or silver-colored dot. The dot will become full or half red or pink when the dot has come in contact with water or a liquid containing water.

CAPpings - Performance Contracts: Shaking Up The Municipal Water Market? - Does this approach open doors for corrosion control leading to water conservation and supply of healthy water?

Performance contracts promise to shake up the municipal water market — and to open the drinking water and wastewater sectors to new heights of innovation, efficiency, and funding opportunities.

This will open the doors for efficient corrosion control to conserve water and avoid contamination.


Performance contracts promise to shake up the municipal water market — and to open the drinking water and wastewater sectors to new heights of innovation, efficiency, and funding opportunities.  As Steve Hoffman  wrote in Planet Water: Investing in the World’s Most Valuable Resource, “the water industry is being  rationalized from a delivery-based approach to a solution-based system.”
Instead of manufacturers delivering equipment to an installation and driving away, or consulting engineers wrapping up most of their work once a new facility is online, performance contracts put the risk — and the reward — of performance on the supplier side.  Contracted operators deliver water for a negotiated sum, or earn their pay as incentives for achieving agreed-upon goals — for instance, cost savings over previous systems. Utilities reduce their up-front expenditures, their risk and, often, the need to go to voters for bond measures.
To investors, that’s like a long, cool drink of water on a hot day.  A contract guaranteeing a certain level of performance, seasoned with the security of working with municipalities on the most inelastic of commodities — it’s a solid bet.  Coupled with growing interest in non-traditional financing tools like public-private partnerships and private activity bonds, performance contracts offer increasingly attractive opportunities for investors, which in turn open up great opportunities for municipalities.

To equipment manufacturers, performance contracts are a call to the drawing board, a chance to grow their business through innovation and product improvement rather than face the gauntlet formed when engineers only specify predictable, plain-vanilla, previously-approved technologies in traditional installations.

To consulting engineers, it’s a huge disruption.  Replacing the old design-bid-build model with design-build-operate or even design-build-own-operate arrangements changes the business model for many consulting firms.  In the new system, the money comes from efficiencies in operating expenses (OPEX) rather than a piece of the capital expenses (CAPEX).  The paycheck is spread over long contracts – no more bid ‘em, build ‘em and move on.

On the flip side, the shift creates opportunities for consulting engineers to focus their training and expertise on pilot testing, creating OPEX efficiencies and overseeing construction.  A lesson from the electric and gas utilities is that scalability — turning successful pilot plants into commercial realities that deliver the same benefits — is a huge challenge, notes Linda Jackman, vice president of industry strategy for Oracle Utilities.  That makes understanding pilot design and scale a key competency for the new generation of successful consulting engineers.

Consulting engineers’ expertise must bridge into the burgeoning world of data, which means tomorrow’s consulting engineers (and many of today’s) need to serve up their hydraulics with a data analysis chaser.

CAPpings - Jewellery - Why does Gold (14 carat) change color or discolor skin? Is it a corrosion concern for jewelry users at the time of soaring Gold price?

Gold itself does not corrode, but its primary alloys of silver or copper will do so—forming very dark chemical compounds—under moist or wet conditions.

If you sweat, fatty acids released by your body can cause corrosion of 14 Karat gold.


Pure gold itself does not corrode, but its primary alloys with copper or silver will do so forming very dark chemical compounds under moist or wet conditions. If you perspire, fatty acids released by your body can cause corrosion of 14 Karat gold. This problem can be worse in coastal and humid areas where sea salt in the air combines with perspiration and discolors skin. The chlorine, which is routinely added to the swimming pools and spas, is one of the worst enemies of gold. Corrosion can weaken gold's structure, eventually leading to breakage.

Article Source: http://www.goldmasters-sa.com/jewelryfacts.htm

Chemicals such as chlorides and sulfides contained in perspiration may react with metals  contained in the gold alloy, causing a black mark on your skin. Eating lots of tomatoes or drinking many cups of coffee may cause problems for some people. Your body chemistry may change from time to time.  A ring which previously caused no problem could suddenly start to smudge your finger. Exposure to chemicals outside the body can also have the same effect. Salt reacts with the alloys in yellow gold to cause corrosion. Eating that box of salted popcorn in the movie may cause your jewelry to darken your skin.

CAPpings - India - Beauty and Fashion - Corrosion (rust) affects beauty of hair

People who have natural red hair look beautiful, but when you inherit the same because of iron and rust deposits, your hair looks ugly. 
Iron and rust deposits on hair are a common phenomenon




It may be caused by well water, excessive hard water or water which comes from old rusty pipes that get iron films on them due to their years of corrosion.

How to Remove Iron and Rust from Hair
-There are popular rust removal shampoos and conditioner in the market, which reduce the orange tint. The usage varies from product to product and one should make sure to read the instructions, before applying the product.
-Rinse your hair with a mixture of vinegar, added with some cream of tartar. Leave it for about 10 minutes and rinse with cool water.
-Another option is to use lemon juice. Apply lemon juice on your hair, leave for 10-15 minutes and rinse thoroughly.
-Mix baking soda with your shampoo. Use this to wash the hair and then rinse with water. Make sure to use a conditioner later on.

Preventive Measures
The remedies provided in the above lines would lessen the redness primarily. However, the problem will tend to continue, unless and until proper preventive measures are taken. Some of them have been mentioned below.
-Get a water purifier for your home or change the water pipes
-Do not use excessive chemicals and avoid experimenting a lot with the use of machines on your hair.
-Do not let your hair remain wet for a long time, as the reaction between iron and water cause rust to occur

CAPpings - India - Improper coating selected for internal corrosion protection of drinking water pipe and tanks puts public health at risk - Toxins in Mumbai's drinking water could hit 7 lakh

Improper coating selected for internal corrosion protection of potable water pipe and tanks puts public health at risk.

Toxins in Mumbai's drinking water could hit 7 lakh people


CAP-cycle Rider: Manish Jhurani

MUMBAI: The BMC may be risking the health of around seven lakh people living in the Sion-Sewri belt following the reopening of the Raoli water reservoir, whose two tanks have been coated with a polyurethane to protect their insides from rusting. A written complaint to the civic vigilance department says that the chemical coating has been done improperly and could lead to toxins being released into potable water. Health experts have said that MDI, a chemical in the coating, could cause respiratory ailments, skin rashes and kidney stones or even increase a person's risk of getting cancer.

A January 13, 2010 letter from the ICT to the BMC states that a visual exam of two samples submitted by the civic body indicates the polyurethane coating in the tanks is "defective'' and has evidence of "unevenness and roughness". Furthermore, the ICT says there is "improper curing of coating material". This means that the two elements that combine to form polyurethane–resin and MDI– have not properly bonded to create the non-toxic film that would allay rusting.

Civic officials and scientists said that the MDI could enter the water and render it toxic. The ICT report says the "material may not provide a protective barrier'' to the steel. "As there is also evidence of coating failure, the material may leach out and affect safety of potable water, even if it complies with test requirements," says ICT's letter to the BMC.

Most jobs on these pipelines are compromised. The products that are being used are mostly substandard. There have been articles in news paper like this one which proves how safe we are drinking this water:

Toxins in city's drinking water could hit 7 lakh - The Times of India http://timesofindia.indiatimes.com/city/mumbai/Toxins-in-citys-drinking-water-could-hit-7-lakh/articleshow/7102877.cms#ixzz189cfvodr

Inspite of this, similar products are used for other pipelines. Moreover, the work going on the eastern express highway for pipeline is going on since past 6 years. all pipes are lined with cement. think about the field joints, condition of cement when exposed for so long, damages/hairline cracks occuring while transportation. These issues can be solved very easily resolved if corruption reduces

India - Water Contamination - Earthworms had fallen out of drinking water taps in around 50 homes in Patna. Civic officials blamed the decades-old pipeline for the problem of unhygienic water supply

Earthworms had fallen out of drinking water taps in around 50 homes in Patna.

Civic officials blamed the decades-old pipeline for the problem of unhygienic water supply


Patna Municipal Corporation (PMC) authorities on Monday asked the technicians concerned to repair the water supply pipelines to the Mangal Talab area in Patna City after The Telegraph reported in its June 18, 2012 edition how worms gushed out of taps at some of the homes in the locality on Sunday.

“I read the report in The Telegraph. We have ordered the officials concerned to repair the water supply pipelines in the area by tomorrow (Tuesday),” said PMC chief engineer Ramsawarath Singh.

He added: “The pipeline in the area was laid a long time back. It is around 7-8-ft beneath the ground. Most of the times, it is difficult to find out where the exact leakage has occurred. But this time it seems that the leak has been caused during repair works.”

Sharma, along with German scientist Dr Hasko Nesemann attached with the Central University of Bihar, also prepared an investigative report on the organism claiming: “On 17th June 2012, an already known large aquatic worm (18cm fully extended) species with the scientific name Glyphidrilus gangeticus Gates, 1958, has been recorded for the first time from tap water in Patna City area near Mangal Talab

CAPpings - India - Leakage of acid water that has affected agriculture fields and aquatic life in Orissa - Change in material for better corrosion resistance

Leakage of acid water that has affected agriculture fields and aquatic life in Orissa.

Change in material from Iron to Fibre didn't solve the public problem: the installation of fibre pipeline was not done properly which resulted in the crack


PARADIP: A day after the fibre gypsum pipeline of Paradeep Phosphates Ltd (PPL) leaked on Monday, fishermen of adjacent areas alleged that dead fish had been sighted at various water bodies.

Officials of the State Pollution Control Board (SPCB) along with local Fisheries Department officials visited the spot on Tuesday morning where the pipe had leaked. The SPCB officials collected water samples from the nearby water bodies for examination. The district administration, on the other hand, has deployed a team to conduct an inquiry into the leakage of acid water from the pipeline and ascertain loss of marine life.

Following government intervention, the plant management changed the iron� pipeline to fibre pipeline. “However, the installation of fibre pipeline was not done properly which resulted in the crack,”

CAPpings - India - At least 250 million litres of water a day, which can cater to two lakh households, is lost every day in Bangalore due to old, rusty pipes and poor distribution

At least 250 million litres of water a day, which can cater to two lakh households, is lost every day in Bangalore due to old, rusty pipes and poor distribution.

37 per cent of water literally goes down the drain


Bangalore thirsts for better water supply

Spiralling population and the Bangalore Water Supply and Sewerage Board's (BWSSB) failure to augment supply has ensured that the city is perpetually in the grip of a water crisis. If the depleting water level in the T.G. Halli reservoir and the delay in the Cauvery Stage IV Phase II scheme are bothering residents and officials, a deeper malaise ensures that the water shortage is perennial: at least 37 per cent of water literally goes down the drain due to old, rusty pipes and poor distribution. Added to this are illegal connections.

The drinking water pipeline network of 7,500 km carries water to 6.1 lakh households. Inequitable supply is the order of the day. While some areas get an enviable supply of water, others have just air in their taps. Engineer-in-Chief Venkataraju admitted that at least 37 per cent of the 900 mld goes waste due to old, rusty pipes and poor distribution. Citing various reasons for the irrational distribution which accentuates the shortfall, he said the city falls short of 883 mld.

While 15 per cent is wasted because of pipe and joint leaks and corroded house service connections, the rest is unaccounted for due to seepage in ground-level reservoirs and malfunctioning meters. “If we can reduce the wastage, we will save at least 250 mld. This can cater to nearly two lakh extra households,” he said.

CAPpings - India - 1000 pipe-bursts reported each year leading the way for Corrosion induced water contamination in Mumbai

1000 pipe-bursts reported each year leading the way for Corrosion induced water contamination in Mumbai




BMC has a tough time maintaining the 4,000-km pipeline network which has been constantly under pressure from a burgeoning population and careless infrastructural work carried out by government agencies. The civic budget has made provisions to increase water sample collection to tackle the situation. The laboratory at G-North ward is being upgraded to test 1,000 samples per day and the laboratory at the Bhandup complex 250 per day.

Mumbai has a network of corroding pipelines and when they burst, waste from sewage lines enters the water supply, leading to contamination. Roughly 1,000 pipe-bursts are reported (each year)," a civic official said.

CAPpings - USA - Infrastructure Upgrade - Water pipelines replacement calls for hike in residential water bill

Aged water pipelines are replaced due to leakage, corrosion and longterm sediment accretion

Pipeline replacement calls for hike in customer (residential) water bill



Illinois American Water Co. is investing $1.2 million to replace water main piping in parts of Belleville, East St. Louis, Granite City and Venice. The original piping is rife with leaks, corrosion and longterm sediment accretion, according Grant Evitts, senior operations manager for the Interurban District. "The water mains we are replacing with this project were installed over 50 years ago," Evitts said. "Upgrading the infrastructure is essential to ensuring quality water service.

According to utility company spokeswoman Karen Cotton, the funding for this project will be provided by revenue from customer water rates. These rates, which aren’t subsidized with taxes or fees, are based on the true cost of providing water service, including water treatment, distribution, customer service, meter reading and infrastructure investments that need to be made to ensure water quality and upgrading of the water main systems.

There will be 1,509 feet of 2-inch galvanized piping replaced with 8-inch ductile iron on Coral Drive from Carlyle Avenue to Gardenia and from Shady Lane to Holly Drive. Later this year, 750 feet of water main will be replaced on South Pennsylvania Avenue in Belleville.

On Oct. 27, Illinois American filed a request with the Illinois Commerce Commission for a rate increase of $7.06 a month to be added to the existing $43.65 per month average residential bill. The review process is pending.

CAPpings - India - Corrosion of water pipeline, a weird excuse for draining water as per central guideline to avoid burst

Corrosion of water pipeline, a weird excuse for draining water as per central guideline to avoid burst.

Most supply pipes in Ranchi are as old as 44 years. Sealing leaks is a difficult proposition in Ranchi

Near Khelgaon Chowk, the damaged drinking water supply pipe from Rukka reservoir is spurting a fountain, sending roughly 500 litres of water down the drain every hour. At Kokar Chowk and Kantatoli Road, the situation is no different. The leaking pipes there are leading to wastage of around 1,000 litres per hour. The total wastage in Ranchi roughly works out to around 40,000 litres per day.

But engineers in the department claim that central guidelines allow a wastage of 10 per cent of the total water released per day. Given that the department releases 3.75 crore litres a day, the wastage due to leaking pipes, they claim, was negligible. What he perhaps meant was that tending to small punctures might augment water pressure through the rusted pipes and cause them to burst.

CAPpings - India - Corrosion leading to leakage of Opa-Panaji Water Supply line in Goa leaves parts of Tiswadi parched for 3 days

Corrosion leading to pipeline leakage leaves parts of Tiswadi parched for 3 days

A corroded, leaking joint on the 900mm Opa-Panaji water supply line at Carambolim was the cause of the problem


PANAJI: The capital city of Panaji and surrounding areas of Ribandar, St Cruz, Merces, Taleigao and Dona Paula reeled under an acute water shortage for the third day running on Saturday, putting residents under much distress.

A corroded, leaking joint on the 900mm Opa-Panaji water supply line at Carambolim was the cause of the problem. PWD had warned of a shutdown for May 24, but the repairs took over a day-and-a-half putting residents in acute discomfort. Flooded with calls from hapless residents from their respective wards, city corporators complained bitterly that PWD engineers were either not taking their calls or repeatedly giving false deadlines and that no water tankers had been pressed into service. PWD chief engineer (I) J Borkar on Saturday afternoon insisted that the department had released water in the morning itself.

There were reports that, cashing in on the problem, some private water tanker operators were charging as much as Rs 2,000 per trip. Worse, citizens were put on waiting lists by water tanker operators and one resident said his number was 300 on the list.
