WORLD TOILET DAY 2020: SUSTAINABLE SANITATION AND CLIMATE CHANGE

 

Climate change is getting worse. Flood, drought and rising sea levels are threatening sanitation systems – from toilets to septic tanks to treatment plants. Everyone must have sustainable sanitation that can withstand climate change and keep communities healthy and functioning. Sustainable sanitation systems also reuse waste to safely boost agriculture and reduce and capture emissions for greener energy. Everyone must have sustainable sanitation, alongside clean water and handwashing facilities, to help protect and maintain our health security and stop the spread of deadly infectious diseases such as COVID-19, cholera, and typhoid. World Toilet Day is a United Nations Observance that celebrates toilets and raises awareness of the 4.2 billion people living without access to safely managed sanitation. It is about taking action to tackle the global sanitation crisis and achieve Sustainable Development Goal 6: water and sanitation for all by 2030. Toilets can help us to fight climate change too! Wastewater and sludge from toilets contain valuable water, nutrients, and energy. Sustainable sanitation systems make productive use of waste to safely boost agriculture and reduce and capture emissions for greener energy. But, what is exactly a sustainable sanitation system? Sustainable sanitation begins with a toilet that effectively captures human waste in a safe, accessible, and dignified setting. The waste then gets stored in a tank, which can be emptied later by a collection service, or transported away by pipe work. The next stage is treatment and safe disposal. Safe reuse of human waste helps save water, reduces and captures greenhouse gas emissions for energy production, and can provide agriculture with a reliable source of water and nutrients.

 

SUSTAINABLE SANITATION AND CLIMATE CHANGE

 

What have toilets got to do with climate change?

The effects of climate change threaten sanitation systems – from toilets to septic tanks to treatment plants. For instance, floodwater can damage toilets and spread human waste into water supplies, food crops and people’s homes. These incidents, which are becoming more frequent as climate change worsens, cause public health emergencies and degrade the environment.

How do toilets protect our health?

4.2 billion people live without access to safely managed sanitation. Instead they often use unreliable, inadequate toilets or practise open defecation. Untreated human waste gets out into the environment and spreads deadly and chronic diseases. Sustainable sanitation systems, combined with the facilities and knowledge to practise good hygiene, are a strong defence against COVID-19 and future disease outbreaks.

How can toilets help fight climate change?

Globally, 80% of the wastewater generated by society flows back into the ecosystem without being treated or reused. Wastewater and sludge from toilets contain valuable water, nutrients and energy. Sustainable sanitation systems also make productive use of waste to safely boost agriculture and reduce and capture emissions for greener energy.

What does a sustainable sanitation system look like?

Sustainable sanitation begins with a toilet that effectively captures human waste in a safe, accessible and dignified setting.

The waste then gets stored in a tank, which can be emptied later by a collection service, or transported away by pipework.

The next stage is treatment and safe disposal. Safe reuse of human waste helps save water, reduces and captures greenhouse gas emissions for energy production, and can provide agriculture with a reliable source of water and nutrients.
