At first glance, the idea of World Toilet Day might be bewildering. But if you’ve ever needed a plumber, you know a working toilet is something to celebrate. World Toilet Day, which will be recognized on November 19th in 2024, exists to remind us that 3.5 billion people – about half of all humans – do not have access to safe sanitation.

A Crappy Situation

Basic facilities – that is, a safe way to manage human waste and access to soap and water to wash hands – are anything but basic. As of 2022, approximately 420 million people still practiced open defecation for lack of available toilets. The good news is that 253 million fewer people relieve themselves outside than in 2019.

Even where toilets exist, 80% of the wastewater produced by toilets returns to the environment without any treatment. And 40% of the world’s population doesn’t have in-home handwashing facilities. Even in America, 63 million people are at risk of drinking contaminated water and almost 2 million don’t have indoor plumbing.

It’s not just gross, it’s dangerous. More than 800 children under the age of five die every day from diarrheal diseases. Adults are susceptible to waterborne illness, too. In 2021, almost 1.2 million people died from diarrheal diseases globally, and according to Our World In Data, 443,832 children were among the dead.

World Toilet Day

In 2013, the United Nations established November 19 as World Toilet Day to help break the taboos around toilets and raise awareness of sustainable sanitation options. Since then, the UN has worked towards the development of safe, sustainable sanitation options to end open-air defecation. The years from 2018-2028 was declared the Water Action Decade to accelerate improved access to safe water and sanitation, and to deal with increasing pressure on water resources and ecosystems, including the risk of droughts and floods.

The focus of World Toilet Day 2024 is the impact of the climate crisis and conflicts on access to safe, sanitary facilities for human waste, which the U.N. describe as a “place for peace.” Inadequate sanitation systems spread human waste into rivers, lakes, and soil, polluting the groundwater, our most abundant source of freshwater. But safely managed sanitation protects groundwater from human waste pollution. The UN Sustainable Development Goal 6 aims to ensure safe toilets for all by 2030; unfortunately, we are not close to meeting this target.

Toilets and Climate Change

Climate change is making sanitation harder. Storms and rising sea levels threaten entire sanitation systems with flooding and contaminated drinking water and food crops. By 2050, up to 5.7 billion people will experience at least one month a year of drought, putting traditional septic and sewer systems at risk. Composting toilets or modern waterless designs may be more sustainable, resilient options.

Sustainable sanitation systems can also be part of the solution to climate change. Reducing water consumption and loss and improving the energy efficiency of treatment systems lowers greenhouse gas emissions. Properly treated wastewater and sludge can boost agriculture. Biogas can also be captured and used for green energy generation.

What Can You Do?

Sustainability starts at home. Find out if your water is safe, and if it is not, take steps to improve it. Learn disease-preventing handwashing technique. Consider whether a composting toilet is an option, and if not, upgrade to more efficient toilets.
