This week at the Case Foundation, we’ve been celebrating entrepreneurs — their role as innovators, job creators and the heart of economic growth — as part of National Entrepreneurship Month and Global Entrepreneurship Week.

It just so happens that within this busy week falls another day that is close to our heart — World Toilet Day — focused on raising awareness of the 2.4 billion people around the world who lack access to clean water and sanitation. Today’s efforts will also shine a spotlight on the incredible people and organizations working towards meeting the UN’s Sustainable Development Goal to ensure access to water and sanitation for all.

For me, it’s a not just a happy coincidence that these two important world celebrations — entrepreneurs and toilets — fall in the same week. In fact, I see them as closely intertwined. Admittedly, it’s an odd couple at first glance… what do entrepreneurs and toilets have to do with each other? Actually, quite a lot.

We talk a lot at the Case Foundation about the role that entrepreneurs can — and must — play to solve some of our most intractable social challenges. And opportunities abound to bring entrepreneurial thinking and approaches to address the sanitation crisis.

One of the organizations living this idea is Sanergy, a social enterprise and a grantee of the Case Foundation. We’ve written about its groundbreaking work in the informal settlements of Nairobi, Kenya and had the opportunity to spend time with the Sanergy team during our visit to Africa this summer. But what’s particularly worth highlighting about Sanergy on this year’s World Toilet Day is its unique approach to leveraging the power of entrepreneurship. Through its franchise model, Sanergy has created a community of 370 micro-entrepreneurs — known as Fresh Life Operators — who purchase and operate Fresh Life toilets, providing their communities with access to clean, safe and affordable hygienic sanitation.

The Sanergy team mentors and assists these entrepreneurs along the way: from providing training in basic business skills, to partnering with Kiva to provide access to interest-free loans, assisting in the set up of savings accounts and holding regular forums on best practices. Creating a community of successful Fresh Life Operators goes well beyond enabling these entrepreneurs to provide hygienic sanitation to their friends and neighbors (via the 764 Fresh Life Toilets deployed to date), but they are also helping them create jobs. To date, nearly 150 Fresh Life Operators have hired attendants to help run their toilets, creating new, steady jobs in an area with 40 percent unemployment.

Sanergy certainly isn’t alone in this endeavor to leverage entrepreneurship to address the sanitation crisis — our long time partner Water for People has piloted a “sanitation as a business” initiative, which it intends to build on in 2016. And WSUP (Water and Sanitation for the Urban Poor) has been a leader in this space, incubating a number of new initiatives that leverage the power of business and entrepreneurship to provide sanitation solutions in places like Ghana, Bangladesh, Kenya and Zambia, through its innovative WSUP Enterprises effort. And companies like Sanivation (an alumni of the incubator program run by our friends at Halcyon House), Pivot, x-Runner Venture and many others are making an impact by providing toilets and removing waste from communities in places like Kigali, Naivasha and Lima. The list of innovative organizations leveraging entrepreneurship to address the range of challenges in the sanitation crisis goes on and on.

It is my hope that someday, we won’t need a World Toilet Day because each and every person will have access to safe, hygienic sanitation, forever. But until that day, let’s celebrate the unexpected and critical role that entrepreneurs and innovators can play in changing the status quo.
