World Water Day

World Water Day, on 22 March every year.

World Water Day, on 22 March every year, is about taking action to tackle the water crisis. Today, there are over 663 million people living without a safe water supply close to home, spending countless hours queuing or trekking to distant sources, and coping with the health impacts of using contaminated water.

The Sustainable Development Goals, launched in 2015, include a target to ensure everyone has access to safe water by 2030, making water a key issue in the fight to eradicate extreme poverty.

In 1993, the United Nations General Assembly officially designated March 22 as World Water Day. World Water Day is coordinated by UN-Water in collaboration with governments and partners.

Each year a new theme is chosen and an array of resources are made available for the public, organisations and schools to use and share – making it easy for you to inform, educate and inspire.

The theme for this year is WASTEWATER.

Why wastewater?

Globally, the vast majority of all the wastewater from our homes, cities, industry and agriculture flows back to nature without being treated or reused – polluting the environment, and losing valuable nutrients and other recoverable materials.

Instead of wasting wastewater, we need to reduce and reuse it. In our homes, we can reuse greywater on our gardens and plots. In our cities, we can treat and reuse wastewater for green spaces. In industry and agriculture, we can treat and recycle discharge for things like cooling systems and irrigation.

By exploiting this valuable resource, we will make the water cycle work better for every living thing. And we will help achieve the Sustainable Development Goal 6 target to halve the proportion of untreated wastewater and increase water recycling and safe reuse.

Are you a waster?

The answer is yes – we’re all wasters when it comes to wastewater: 80% of it just flows back to nature untreated, polluting the environment and wasting a precious resource.
Let’s reduce the quantity and pollution of our wastewater, and safely reuse as much as we can.
So, don’t be a waster. Reduce and reuse wastewater.

How FLOW is contributing to the Wastewater Solution

Genius of SPACE

The Genius of SPACE project is building innovative water and waste treatment solutions in Langrug – an informal settlement in the Western Cape, South Africa.

The project uses Biomimicry principles to clean up the grey water, storm water, and solid waste challenges that the community face.

These low tech, easily maintained solutions will help to address the key challenges faced by this community such as health and well being.

Do what you can, do it with others, and do it with passion.
