14 Social Enterprises Making Clean Water and Sanitation Accessible for All

Alexandra Nemeth

Senior Manager, Content Marketing & Storytelling at MovingWorlds

What are the first things you tend to do when you wake up in the morning? Chances are washing your face, using the bathroom, and drinking a glass of water are all on that list. 

Access to clean water and sanitation are basic human rights, but according to the UN the reality is that 1 in 3 people worldwide don’t have access to safe drinking water, 2 out of 5 don’t have access to handwashing facilities, and 673 million people don’t have access to safe and clean toilets. 

The COVID-19 pandemic has made the need for equitable access to Water, Sanitation, & Hygiene (WASH) solutions even more urgent: clean water and sanitation are critical to preventing and containing diseases. 

The reasons for these inequities are complex and systemic, and ensuring equal access at scale will take serious innovation and collaboration. But as we see over and over, despite these obstacles, it’s social entrepreneurs who are on the front lines deploying solutions that meaningfully move the needle on SDG 6: Ensuring Access to Water and Sanitation for All.

Below are 14 inspiring social enterprises from the MovingWorlds S-GRID community, and beyond, on the front lines of realizing that vision, both individually and in partnership with other ecosystem actors. Continue reading to learn more about their work and how you can support them: 

PurePaani Portable Filters

PurePaani is an India-based social enterprise on a mission to make clean drinking water available to all. 163 million people in India lack access to safe water as 70% of groundwater is contaminated due to sewage and industrial pollutants.

PurePaani also offers consulting services to help manage and sustain the whole cycle of a water intervention project.

WASHKing is a Ghanaian social enterprise providing low-income and underserved communities with access to sustainable sanitation products at an affordable price. WASHKing produces, supplies and installs environmentally friendly biodigester toilets made out of eco-friendly materials for low-income urban households and institutions to improve health and economic conditions on the continent. WASHKing’s technology treats waste on-site and does not require piping the waste off-site for treatment. The treated waste serves as manure and water for agricultural use, creating additional value for customers and for the environment. Its flexible payment terms, training on hygiene and after-sale services ensure that customers can get the maximum benefit from improved sanitation solutions.

EOS International

In Central America, more than 85% of people don’t have access to safe drinking water, and contaminated water is the second leading cause of death for children under the age of 5. Most of these deaths are preventable, and EOS International is a social enterprise on a mission to make safe drinking water accessible throughout the region. EOS’ water purification technology is a low-cost, low-maintenance solution that attaches to any rural community’s water tank and inactivates pathogens in water systems by releasing a controlled dosage of chlorine. One system can provide clean water for up to 1,000 community members and requires no energy to use. EOS ensures successful, sustainable impact by also educating beneficiaries on how to use, maintain, and repair their technologies, and offers on-site support as needed.

Sanivation is a Kenya-based social enterprise that partners with local governments to deliver clean, safe, and efficient sanitation services to urbanizing communities in low-income countries. It does this by converting waste to industrial fuel as a sustainable option for boilers and kilns. Sanivation employs a systematic approach with its partners to design, build, and train local staff on how to manage non-sewered sanitation services that meet the environmental and cultural needs of specific locations.

Hydrologic (aka Tunsai Water)

Hydrologic is a social enterprise that manufactures, distributes and sells ceramic water filters across Cambodia. About 72% of rural households treat their drinking water by boiling it, which can be inconsistent and requires energy, typically in the form of charcoal or wood (both of which result in greenhouse gas emissions and deforestation.) Hydrologic saves about 130,000 tons of CO2 every year by shifting customers away from using wood or charcoal and instead towards a more sustainable water filtration method.

Almost half the global population lacks access to safe sanitation. Loowatt’s unique toilet system integrates revolutionary waterless flush technology with 360-degree waste processing to deliver hygienic and safe toilets for domestic and commercial applications. The toilet itself is very similar to a normal, high quality, household flush toilet, however: A liner sitting inside the toilet bowl safely and hygienically captures human waste, which is sealed and pulled through to a barrel below with each flush. This seals away germs and odors, leaving a clean bowl every time. Once full, barrels are replaced. Waste can then be processed in a range of systems, from small decentralized digesters or larger, utility-run treatment sites. It can be converted to biogas to generate electricity, cooking gas, or organic fertiliser.
