ABU DHABI // A simple copper device based on an ancient method for storing water may save the lives of millions of children around the world, experts say.
Dr Ahmad Khalid, who was raised and educated in the UAE, is managing a project that is hoped to make water containing deadly bacteria safe to drink.
The device, now undergoing year-long tests in Kenya and India, is a coil of electric copper cables that is suspended in water. It has been proven in the laboratory to kill the pathogens.
About 2.2 million people die of infectious diarrhoea every year, mostly children below the age of five and mostly in developing countries, said Dr Khalid, 29, a Jordanian.
“The device could prove to be one of the simplest and cheapest ways to purify water from enteric pathogens,” said the former pupil of the American International School in Abu Dhabi.
“It does not require energy to function, lasts a lifetime and is easy to use in a rural household. It could help save millions of children across the world, particularly in developing countries like Kenya and India.”
The inventor of the device, Dr Padma Venkat from India, observed that if a small copper coil were left in a container of water overnight, virtually all deadly water-borne pathogens were killed and the water became potable.
Copper generates free-radical ions, which quickly break apart and kill bacteria that cause water-borne diarrhoea, said Dr Khalid.
“We demonstrated that the ancient Indian practice of storing drinking water in copper pots is a simple way to get rid of diarrhoeagenic bacteria,” he said.
“Since copper pots are expensive we have developed an innovative device, which is a cost-effective adaptation of this practice.
“It has the flexibility to be used in any container, is durable, easy-to-use and maintain. Early evidence suggests that it works under laboratory conditions and is safe.”
Field-testing began in poor urban and rural households in Kenya and India last month, with a C$100,000 (Dh353,500) grant from Grand Challenges Canada. Dr Khalid lives in Ottawa.
The trial is being held in 200 homes in the slums of Chennai, sample communities in Kwale County in coastal Kenya, and a slum area around Nairobi.
“We will document its effectiveness, safety, factors affecting its acceptance and uptake, and propose a business model for its eventual scale-up,” said Dr Khalid.
“By the end of the 12-month trial we expect to see water contamination reduced, the incidence of diarrhoea coming down and, hopefully, people will be accepting the product.
“If all goes to plan, we will have a low-cost product that can be manufactured locally in bulk by community-based businesses.”
The next step will be to apply for a Grand Challenges Canada phase 2 grant of up to C$1 million to develop a business model for production and distribution, with the involvement of the communities, government and enterprises.
If the field trial is successful the device will be commercially made. Its market price is about C$10 for use in 10-litre water containers and it lasts a lifetime.
“It may further work out to be cheaper when commercially manufactured. The coil could enter production in as little as 18 months from now,” Dr Khalid said.
Conventional water-treatment methods such as chlorination, filtration and energy-intensive boiling are impractical in the rural areas and urban slums of developing countries, he added.
He said the copper device was useful in killing water-borne pathogens such as E.coli and Vibrio cholerae.
Dr Khalid said 88 per cent of diarrhoeal diseases worldwide were attributed to contamination of drinking water by microbial pathogens.
The project is a collaboration between Dr Khalid, Dr Padma Venkat, director for the Institute for Ayurveda and Integrative Medicine in India, and Kenyan Dr Caroline Kisia, the executive director of Action Africa Help International, a non-government organisation based in Nairobi.
All three are part of the International Masters for Health Leadership programme at McGill’s Desautels Faculty of Management in Montreal, Canada.
Dr Khalid lived in the UAE for almost 16 years before attending university in the United States.

Aged 18-24 months: If screens are introduced, it should be high-quality content watched with a caregiver to help the child understand what they are seeing.
Aged 2-5 years: Limit to one-hour per day of high-quality programming, with co-viewing whenever possible.
Aged 6-12 years: Set consistent limits on screen time to ensure it does not interfere with sleep, physical activity, or social interactions.
Teenagers: Encourage a balanced approach – screens should not replace sleep, exercise, or face-to-face socialisation.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

Real estate tokenisation project
Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.
