5 inventions that purify drinking water

October 23, 2022

We live in an age defined by life-enhancing technologies. According to the World Health Organisation, 2.1 billion people lack access to a safely-managed drinking water supply at home. Contaminated or dirty water causes 6,000 deaths every day, as 3 in 10 people risk catching water-borne diarrheal diseases including Cholera and other serious illnesses such as Guinea Worm, Typhoid, and Dysentery each time they take a drink.

A lack of access takes a toll on the young. A new-born child dies every minute  from water-related disease. Every two minutes, poor sanitation  kills a child under five.

Access to microbe-free water is the cornerstone of sustainable communities

Portable drinking water, supported by basic sanitation, allows communities to grow and thrive. Experts estimate  universal access to clean water and sanitation  would produce economic benefits through:

  • Enabling hospitals to reduce child mortality rates;
  • Improving a population’s ability to fight disease;
  • Promoting gender equality in lower income countries, where women bear the responsibility of collecting water reducing their productivity

Organisations across the world have committed to developing innovative, forward-thinking solutions that help isolated populations, access water; such as these five ethically-minded, sustainable technologies.

Seon Mobile Water Purifiers

Wananchi UK sought an alternative solution to single-use plastic bottles when offering a safe supply of drinking water. They came up with Seon Technology: a reliable, mobile water filtration system that purifies fresh or seawater straight from the source using hospital-grade filtration cartridges and running of solar power where required.

Their devices come in several formats; from a portable box to larger-scale trailer system, to the high-output containerised purifier suitable for the hardest-to-reach parts of the world where water quality is particularly poor.

Life Sack

Inspiration for  Life Sack  came about as NGO’s were delivering food to remote populations and the bags the NGO’s used going to waste. Families can now fill the emptied sack with contaminated water, which the sustainable plastic purifies through a Solar Water Disinfection Process using UV-A light and heat to kill bacteria and remove undesirable microbes.

NGO’s ship in bags full of food and rural communities receive a life-long supply of purified, safe-to-drink water.

The Drinkable Book

Hygiene and sanitation best-practice stems from education. Researchers at Carnegie Melon University created an affordable teaching resource that doubles as a filtration device.

The Drinkable Book contains basic guidance for maintaining clean water sources, with the information printed on filtration paper and provides filter sheets to last four years. The current focus is on developing nations, including Ghana, Kenya, Haiti, Ethiopia, India, and Tanzania.


Filtration is useful where water is abundant and  water scarcity is quickly becoming a global crisis. What happens where communities face a  severe water shortage? This is where the WaterSeer technology comes into play.

The device is planted six-feet underground, using above-ground wind turbines to force air down into a cooler chamber. As the hot air enters cold surrounds, vapor condenses and filters to the bottom of a tube, which users extract the water with a pump and hose. Developed by VICI Labs in the USA, the device was recognised as 2017’s Emerging Tech Innovation of the Year. It can collect up to 37 litres of water a day and is currently in use in Karachi, Pakistan – a notoriously dry region of the world.

The Hippo Roller

Millions of women and children walk 6 hours every day, just to collect water, carrying heavy buckets on their head. Though not a purification device, the 90-liter Hippo Roller offers them a less strenuous vessel to transport clean water, collecting up to five times more liquid than a bucket. Developed by two South Africans in response to localized struggles, it’s a unique solution whose impact on women and children has been praised by the UN World Food Program. It is now used in more than 20 countries worldwide, with 50,000 rollers helping close to half-a-million people.

As a social enterprise, the company encourages corporate sponsorship to facilitate global distribution with associated branding opportunities.
