Access to hand washing in Africa is limited due to lack of facilities and water resources, which limits preventative measures in times of pandemic. We created a portable, low-cost, water-efficient hand washing system that is easily scalable across households and public spaces in low-income and crowded communities to limit the contact spread of disease. If scaled globally, our solution will increase hand washing facility access in communities and limit the spread of many communicable diseases in populations that are most vulnerable, while increasing hygiene and instilling hand washing habits in populations.
Hand hygiene practices have been identified as one of most reliable methods to prevent spread of infection and pathogen contamination by the World Health Organization. Several regions around the world do not follow these practices due to limitations in resources available, especially in Africa, where the majority of the population do not have access to hand wash facilities. A reported 115 people die every hour in the region due to poor sanitation and nearly 41% have no hand washing facility access. This is one of the main reasons why disease outbreaks such as H1N1, MERS-Cov, Ebola and COVID-19 have severely affected this region.
With the prevailing COVID-19 pandemic affecting several countries around the world, Africa is most at risk of becoming the next large epicentre for the disease in the upcoming months. The WHO estimates that Sars-Cov-2 will infect ¼ of the African population and cause 190,000 deaths by the end of this year. To limit the spread of the disease, early precautionary measures need to be taken that would protect the population from being infected and assist it in limiting the spread.
WaterWorks focuses on helping Africans in densely populated regions by providing a hand-washing system that will enhance hand-washing facility access and improve hand hygiene practices for individuals with the goal to prevent community spread of pathogens by contact. We focus on providing a portable hand washing station that is exceptionally water-efficient and cost-effective for low-income and densely populated regions.
Our system consists of a double reservoir with clean water in the base vessel and grey water collection in the top vessel. It is operated by a foot pump mechanism that requires no electricity. The top vessel is easily removable for easy disposal, and the tubing is easily removable to facilitate filling of the base vessel. Our testing reveals: 250 hand washes can be achieved per 10L of water, averaging 40mL per hand wash, which is 11x more water efficient than the currently used continuous flow gravity based hand washing solutions. In addition, the portability, easy scalability and simple mechanism of our system makes it easily accessible to households and public spaces in even the lowest income, isolated and water-scarce communities in Africa and the world.

Currently, hand washing systems in vulnerable African communities are either non-existent, or centralized (not ideal for social distancing and high frequency hand-washing necessary in pandemic) + water-wasteful (not ideal for water-scarce environments requiring frequent trips to nearest water source). These communities are also most vulnerable to disease outbreaks, due to poor hand washing material access and sanitation behaviours, predisposing conditions, and limited access to healthcare facilities. Our product is portable to provide easy filling & presence in every household (allow for social distancing) & exceptionally water and cost efficient.
Our initial focus will be regions in Nigeria, Ghana and Sierra Leone focusing primarily on densely populated, low-income communities. We wish to partner with existing organizations and WASH programs to implement our system. Our future plans involve potentially manufacturing the system in Africa using recycled materials to create an eco friendly and local solution, and partnering with the government and education systems to introduce the system in schools and refugee camps in order to increase access to hand-washing facilities and to instill good hand-washing habits. We aim to directly partner with leaders of these communities to analyze the value that our system brings and improve it based on their needs.
Our identified problem and solution relate very well to the challenge because we chose to develop our solution in light of the current COVID-19 pandemic and with future pandemics in mind. Hand washing is the most effective preventative measure for nearly ALL communicable diseases, yet only 41% of the world's population have access to a hand washing station. These two facts mean that the majority of the world population cannot practice even the most basic and simple solution to protecting their health. Our solution is here to change that, by providing hand washing for all.
