The hardest aspect, says Chandra, is the pressing need to educate his target customers.  Many of the rural poor lack the knowledge to appreciate the link between contaminated water and disease.

Often, he gives away one filter to a family and allows them to experience the improvements and the numerous intangible benefits in the form of better health, less absenteeism and improved income, or children being better able to focus on their education.

Such breakthroughs are critical, as beneficiaries then create a trickle-down word-of-mouth effect and effectively become Watsan ambassadors.  Says Chandra, “if we are persistent and consistent in alleviating the pain of target customers, we don’t need to search for a market, it comes to us.”

Interestingly, Watsan’s marketing team comprises members who have trained in social work or those who have previously worked at grassroots level organisations.  This team is able to emphasise the educational aspect of marketing their filters and convey the pertinent message to benefit the populations they serve. Most of his team have joined Watsan out of respect for Chandra’s mission to improve the lives of the poor, demonstrating a true commitment to their target clientele.

As such, Chandra is clear that he is not forcing his product on the market, on the contrary he is motivated by the need to improve the lives of those that most need it.  Whereas a visit to a village that results in no sale may be seen as failure, Chandra looks at it differently.  He stands firmly by his overarching goal of providing a pertinent solution to a very real problem; with the mission of improving peoples’ lives.

In the beginning, Chandra built each product himself, undertaking the entire end-to-end process entirely unaided.  Today, he has employed 40 workers who are responsible for building filters.  However, he sincerely believes that the journey to being a successful entrepreneur is paved with hard work, rolling up ones’ sleeves and putting in the early effort before any rewards can be reaped.

Another steep learning curve for Chandra has been in identifying the right partners to work with, particularly the non-government organisations (NGO’s) that work at grassroots levels.  “Social change is not a one-day job,” he says, while expressing his appreciation for organisations that aim to make a long-term impact.  One organisation, for example, was committed enough to test his water filters for efficacy at 180 different sites, providing validation and demonstrating their own commitment to his cause.

Through his journey, Chandra has been gratified to meet fellow philanthropists, who believe in using technology for the benefit of the underserved masses.  As an example, his fluoride filter was developed at an Indian university that allowed him to adapt their technology for no charge, with the aim of bolstering his cause.

He believes that adopting a positive spirit and focus attracts the help and goodwill of like-minded people, which allows for the best possible outcome.  He says things fall into place when the focus is helping others – focus not on big money but on big impact, he says.

Among his memorable, proudest moments are a video he received from flood-hit Kerala, where his product was in use to purify flood water. This strengthens his resolve to continue on this journey irrespective of its challenges.

Another inevitable facet of entrepreneurial life is stress, which he says he tackles through his many hobbies, among them painting, temple conservation, and conducting heritage tours of temples on weekends. He also gives back by mentoring schoolchildren who have business ideas and helping the next generation of changemakers.  Of achieving this all-important balance, he says, “it’s all about how you keep yourself happy.  Giving back energises you.”

Watsan’s motivation is alleviating the problems faced by rural poor by providing a relevant product.  Chandra is proud of how his product has evolved – it has been endorsed by prestigious bodies like Indian Institute of Technology, and is certified as using high quality food-grade plastic, having been tested under different geographical conditions and passed with flying colours.

This is also well reflected in Watsan’s financials, with revenues more than doubling every year.  For this happy development, Chandra credits his decision to focus on the 85% of India’s population that is rural based and addressing a clear gap in this neglected segment.  Watsan has also expanded beyond Indian shores, having made successful forays into Rwanda and Nigeria.

To budding entrepreneurs, Chandra says, “focus, focus, focus. Don’t give up halfway through. Be true to your innovation, make it your passion and do not be discouraged where you encounter criticism.”

To potential investors, Chandra has a simple message – his is a viable business that comes with fulfilment and “happiness quotient”.
