Groundwater is focus of World Water Day 2022

Today, 22 March, is World Water Day (WWD) – 24 hours devoted to highlighting the importance of fresh water and persuading leaders and populations alike to manage freshwater resources sustainably.

This year the focus of the annual United Nations event is on groundwater – located beneath Earth’s surface amid rock and soil and in the fractures of rock formations.

As a company dedicated to helping save the planet, we at Propelair have been reflecting on WWD today, and on groundwater especially.


About 30 percent of all readily available freshwater in the world is groundwater. It may be underfoot and invisible, but groundwater is a hidden treasure, accounting for almost all the world’s liquid freshwater. As the effects of climate change become clearer, it will become ever more critical.

But groundwater is increasingly used to support growing populations and as a buffer against scarcity, so we must work together to manage this precious resource sustainably.

Water-stressed areas

In less than four years, half of the world’s population will be living in water-stressed areas, the World Health Organisation reported last March, while 2.3 billion people live in water-stressed countries, according to UN figures.

Propelair is part of the solution to threatened groundwater resources. By reducing water used by 84% compared to standard toilets, our technology eases the pressure on water supply.

Further, by lessening the amount of toilet-generated waste water, our water-and-air flush action greatly decreases the volume of sewage released.

Our advanced water-saving technology can dramatically reduce water usage in areas of water scarcity – whether or not centralised supply systems are already in place.

Water in buildings

In more advanced economies, less water pumped into a building means proportionately less water out.  The adoption of Propelair’s by governments, businesses and other institutions is having a significant and growing, positive effect on the availability of clean drinking water.

At the same time, using less water delivers benefits in terms of carbon footprint – reducing the energy required to process waste water by up to 80%.

Cutting pollution

Water pollution has many causes and contributors – water and sewage effluent, agricultural and industrial pollution, exacerbated by rising population, improved living standards resulting in greater water use, even changes in the natural hydrological regimes of rivers and lakes due to volumes of water abstracted for hydropower and cooling.

Put simply, by reducing the amount of water sent down drains every day, we can cut down on the total amount of wastewater treated and pollution caused – something to remember on World Water Day.
