5 Facts About Water Scarcity


The Reality of Water Scarcity

Approximately 70 percent of the Earth’s surface is covered in water, and with a number like that, it’s easy to misunderstand the reality of water scarcity. But the truth is, less than 1 percent of the Earth’s water is unpolluted, potable and fit for consumption.² So while our continents may be surrounded with water, sustainable practices and water conservation have never been more important to combat the very real threat of water scarcity.

Availability Versus Usability

Unfortunately, plenty of rainfall or an abundance of naturally occurring freshwater does not mean that an area can’t experience water scarcity. How water is conserved and used in the community, and the quality of the water available, are all factors that affect whether there is enough water to meet the demands of households, farms, industry and the environment.¹ Without proper rainwater collection methods, including testing and treatment, even areas that experience abundant rainfall may have periods of water scarcity.

Rainwater and fresh groundwater are not necessarily fit for use without treatment, making these seemingly available resources difficult to access. MECO works to develop both effective and sustainable water purification systems because the ability to test and treat water for all uses, not just consumption, is crucial. Without proper tests and treatments, an area’s inhabitants or farming industries risk consuming or using polluted water sources.

Necessity Versus Safety

As population, urbanization and water usage continues to rise, demand for water continues to grow and the supply cannot keep up. In fact, water scarcity now affects one in three people on every continent across the globe.¹ That means worldwide, nearly a billion people have limited access to clean water. One fifth of the world’s population walks an average of 3.5 miles a day to collect suitable drinking water. These communities rely on water that is not safe, because the infrastructure does not exist to collect and treat water from aquifers.¹ In those situations, bathing and cleaning can’t be done properly, because they must use water that has not been purified. If they try to store water in their homes, they risk creating an environment of contamination and mosquito breeding, which leads to the spread of diseases.¹

Proactivity Versus Immediacy

For those who don’t regularly face water scarcity, it’s almost hard to believe that this resource could ever run out. After all, the Earth is covered in water! But the reality is, if you could put all the world’s water into a gallon jug, the fresh water available for use would equal about one tablespoon.² Conservation should not just be seen as a proactive movement for the future, but as a necessary part of life today. When you make water a priority, you make people’s lives a priority.

Sustainable water practices can be exercised on an individual level, but they should be prioritized on the industrial front as well. MECO has been 100% dedicated to providing sustainable water purification technologies for 90 years and counting. It’s more than a commitment to us, it’s a mindset and everything we do. Our innovative technologies make water accessible now and for years to come.
