There are many technologies that help on making cost effective clean water accessible to all people as;
Life straw, a small cigar-shaped tube packed with some truly innovative engineering. This clever design purifies water from potential pathogens like typhoid, cholera, dysentery and diarrhea all before they reach your lips.
Ceramic water filters, these water purification devices are made from fired clay, and the tiny pores of the ceramic material are small enough to remove virtually all bacteria and protozoa. The design utilizes gravity to facilitate the filtration process, resulting in a flow rate of 1-3 liters per hour.
Cycloclean, a water-purifying bike initially designed for use in remote villages and disaster zones, it harnesses kinetic energy to purify water, and users can ride the bike to any nearby body of water for immediate access to a source of potable drinking water.
Pure Water Bottle, a device that is capable of filtering soiled water in two minutes by using a combination of 4 micron-sized water filters and a wind-up ultraviolet light system, this combination removes up to 99.9% of impurities from any water source, and it could be a valuable asset for most people in our countries.
With all these as examples, it Clearly tells us that lack of cost effective clean water technologies is not the major problem but lack of channels for dissemination of these technologies to help people learn how to use them is still the major challenge to clean water access among the most communities in Africa today.
With the creation of clean water resource centers at village levels, with workers equipped with the knowledge on how to make these cost effective clean water technologies, they will form groups among the members of the community of which through these groups, they will teach them all these technologies so that rural people who are most vulnerable in accessing clean water can purify it for themselves hence a solution to inadequate access to clean water in Africa.
With the resource centers, people will learn how to make clean water by themselves and this will help to solve on one of the main issues of clean water access which is economical distribution of water to rural and low-income areas since most people will have learned on how to make their own water clean, so there will be no need to cry to their governments to provide them clean water.
This approach will help to address the very real problem of inequitable distribution of water resources because in most of our countries, clean and cheap water is mainly available to the rich while the poor have to seek out supplies, at higher costs, from intermediary providers or unsafe natural sources and I believe that the technological solutions to the world’s water problems must be based on flexibility so that they can be easily learned and implemented among all groups of people in Africa.
