Problem: What problem is this initiative trying to address?

According to the WHO and UNICEF Joint Monitoring Programme Report of 2015, 663 million people, 1 in 10, lack access to safe water. o Its estimated that over 1.4 billion people in 36 countries will be without proper drinking water by the year 2025. Due to the conditions of sanitation and resultant water borne diseases, in India alone o 1.5 million Children die of diarrhoea every year. o Cholera and typhoid cause widespread casualty. o 73 million working days are lost to water borne diseases each year

Solution Summary: What is the proposed solution? What do you see as its most promising aspects for creating shared value?

The Taraltec™ Reactor is a device that uses bio-mimicry to eliminate water borne diseases. It weighs just about 800 grams, and can be simply and easily retrofitted into any existing borewell handpump. The Reactor has been designed to fit into the India Mark II handpump, the world’s most widely used borewell handpump. (The pump is installed on top of a drilled well and lifts water from the bottom of the borehole, through repeatedly moving the pump handle up and down manually). Such pumps are used incessantly by an entire community. A single borewell handpump may service 30 to 40 families, with women and children lining up to use each pump from dawn till dusk. The Reactor has very low capital costs, has nil operating costs being maintenance free, and requires no specialized skills to install – it can be fitted within half an hour by a local plumber following the instructions sent along with the device. The Taraltec™ Reactor is for a lifetime of use & needs no consumables

Impact: What is the impact of the work to date? Specify both the social and the environmental impact of your work

The beneficiaries are those who reside in underserved rural regions of the world. In India, more than half this segment depends on groundwater aquifers for their need of freshwater. There are more than ten million India Mark II borewell handpumps in India alone, many in remote villages, who need to be protected from waterborne diseases like diarrhea, a potent killer if left unattended. Quantifiable data is extensively available from government reports. Waterborne diseases a leading cause of childhood death. Plus, diarrhea a key cause of stunting at a young age. As adults, considerable economic burden of days lost at work. Impact will be in removing both burdens – the saving of lives and the lost economic costs. At the implementation end, we have reached out to various corporate Foundations who do philanthropic work in rural areas. Each handpump typically serves 30 to 40 families and each village has about 6 handpumps. We have installed base of 100 devices & rapidly growing.

Financial sustainability plan: How is this initiative financially supported? How will you ensure its financial sustainability long-term?

Initially Grants & award monies(75%) and also earned income(25%). The earned incomes is from corporate social responsibilities (CSR) programs of large corporate entities, NGOs, Philanthropic Foundations and high net worth individuals buying our product for fitment in the underserved areas. Being in its initial phase we have already started generating revenue with extremely encouraging field trial results from government labs, for our borewell handpump Reactor. The reason we seek support from Grant monies is that we can expand the footprint far more rapidly, and in a sustained manner in wider swathes of geographical areas (e.g. taking an entire set of villages at a time), without waiting for companies to purchase - who would fit the device in a few villages.

Unique value proposition: What makes your initiative innovative? How does your project differ from other organizations working in the same field?

The Taraltec™ Reactor is a patent applied for innovative technology. It significantly eliminates pathogens in the water discharged from handpumps or other pressurised water lines. There is no equivalent product in the world In nature, an Alpheidae attacks its prey by shooting jets of water by snapping its claw, causing cavitation bubbles to form as the ambient pressure goes below the vapor pressure. The bubble implodes on pressure recovery, generates shockwaves, physically killing microbes

Founding story: Share a story about the "Aha!" moment that sparked the beginning of this initiative.

We were using this scientific phenomena for effluent treatment & cooling towers when the idea of miniaturizing the device for the borewell handpump struck and preliminary trials proved the hunch right. Then we got the design right to exactly fit inside the handpump...something that is still evolving, for other applications such as for disaster management (in floods, a critical issue is with waterborne diseases). That can be taken care of, via Taraltec interventions.

Thanks Jonathan.
This technology has huge potential as it does not require maintenance and has no opeation cost or consumables.
