For many people in rural Kenya, purifying water by boiling it is prohibitively expensive and is limited by the availability of raw materials. Innovators behind this project have developed the CeraMaji Ceramic water filter that uses clay and sawdust or sugar cane to remove 99.97% of Giardia and coliform bacteria from local stream water. The CeraMaji filters will be manufactured at a large, new factory in Kenya.

A groundbreaking water purification device that powers itself by producing electricity from any source of flowing water has been created through a partnership between H2O4ALL and Formarum, a Canadian engineering company. Based on conventional copper–silver ionization, the technology needs no external power source and can automatically adjust the disinfection rate required – both features being of great importance in regions lacking reliable electricity sources and technical expertise.

This project will leverage a corporate social responsibility model to finance the sustainable production and distribution of a novel, durable water-treatment product for vulnerable families in hard-to-reach communities that depend on turbid river water.

This project will build a modular, low-cost biofiltration system to improve access to safe water in rural areas in the Philippines, and will develop a business model for commercializing the technology.

An affordable, stable monitoring system developed by this project will detect pathogens in water supplies, signalled by a simple, immediate readout colour change from red to purple.

A 2008 WHO report estimated that up to 70 million people in Bangladesh drink water that contains unsafe arsenic levels.  A simple, low-cost, paper-based test for arsenic developed by this project will help forewarn people when water’s arsenic content exceeds safe levels.

In developing countries, the most common way of treating household water is to boil it, which results in other risks, such as lung disease, burns, fire-hazards and deforestation. A simple, user-friendly household water filter developed by this project, in combination with an innovative business model, offers the promise of safe drinking water for millions of families in developing countries.

The project aims to evaluate potential of agricultural/industrial solid wastes, such as sugarcane bagasse, leechi peel, and a novel iron green-rust as economical sorbents for removal of As (a class 1 human carcinogen) from polluted drinking water.

Sabio proposes to develop a novel, self-contained, field-usable rapid microbial water quality test. Given within 60 minutes, results which currently take 24 hours or more and empowering water providers and citizens to ensure delivery of safe water.

This project seeks to produce low cost water purification aids in form of capsules made from Moringa oleifera seed extract. This seed extract effectively purifies impure water, eliminates germs and holds onto toxins and organic matter. The produced capsules shall be distributed to rural dwellers who do not have access to potable water in Eastern Nigeria. The outcome shall offer greater opportunities to large scale community water projects and institutions.
