Behavior Change and Technology: The Keys to Solving Global Water and Sanitation Issues
For people in the developed world, it is difficult to comprehend living without running water or a flush toilet. Even more difficult to understand may be that in some places, having these amenities is not the most feasible, cost-effective or beneficial solution. The need for technological innovation to solve access to clean water and improved sanitation, as well as to ignite behavior change has never been greater, or more promising.
In 2010 the United Nations (UN) General Assembly recognized water and sanitation as a human right. Great progress has been made to increase access to clean drinking water, however targets for improved sanitation have fallen short, leaving nearly 700 million people without ways to safely dispose of human waste. In fact, globally 80 percent of wastewater generated by society goes back into water sources untreated, which leaves 1.8 billion people drinking and cooking with water contaminated with feces.
The benefits of WASH (water, sanitation and hygiene) interventions include improved health and nutrition, school attendance (especially for girls), and overall productivity, with less time spent collecting water. Improved sanitation also contributes to economic development by delivering $5 in social and economic benefits for every $1 invested, according to the Bill and Melinda Gates Foundation.
Additionally, research demonstrates that designing WASH technology without changing end-user behavior is less likely to succeed. Technologies such as PotaVida’s Smart Solar Purifier, WASH programs implemented by Splash, and community-designed water system with Water1st, are enabling behavior change and ultimately, long-term sustained clean water system in developing countries.
Between 1990 and 2015, 2.6 billion people gained access to improved drinking water, which included piped water connections, public taps, protected wells and boreholes, as well as filtration systems. However, only five to 25 percent of these water purification methods were used correctly. This is why changing behaviors in WASH is so critical. While access to clean water has made greater strides than access to improved sanitation, where 2.4 billion people still do not have basic sanitation facilities, all areas of WASH need to include behavior change to succeed.
The majority of people lacking improved water and sanitation live in rural areas in sub-Saharan Africa, Southeast Asia and Southern Asia. While people in urban areas have greater access today, urban areas also need attention. This is why new technologies, especially those that enable behavior are so crucial for WASH interventions, and the development sector is working on innovative and cost-effective ways to test and treat drinking water, as well as develop new methods for assessing safe collection, transport, disposal and reuse of fecal waste along the sanitation chain. There are a number of promising technologies for cleaning drinking water. Engineers are also working to make desalination less expensive by reducing the energy required for the process. Technologies are also being created to improve recycling of wastewater and sewage treatment for irrigation and industrial use, as well as to resupply aquifers.
In addition, technology can help encourage, enable and empower sustainable behavior change around WASH. All WASH practices, even hand washing with soap, require some physical product or technological component, and the design of these can strongly influence their acceptance by communities. Placement is often key, as well as physical characteristics, such as the design of soap containers and water taps.
Here in Washington State there are a number of organizations using technology to reach the Sustainable Development Goals focused on WASH. For example, The Bill and Melinda Gates Foundation started the Reinvent the Toilet Challenge in 2011, which has now awarded 16 researchers around the world with grants to utilize innovative approaches for the safe and sustainable management of human waste (see one example here). Additionally, The Gates Foundation provides funding to researchers who are developing ways to process and convert waste into products, energy, and fertilizer. Other organizations such as World Concern and Splash (see a list of other organizations below) are also using innovative technology.
While ensuring all people have access to improved water and sanitation will not be easy, the use of new technologies will help create sustainable solutions in places where piped water and flush toilets are not feasible.
A number of Global Washington members work tirelessly to provide access to clean water and improved sanitation. Below are descriptions of just a few of these organizations, highlighting current projects. Learn more about these members and others on GlobalWA’s interactive map.
