Safe drinking water is essential to good health. However, in resource-poor settings, water often comes from unsafe sources and carries deadly pathogens. The World Health Organization estimates that 1.8 million people die each year from diarrheal diseases, many of which are attributed to unsafe water. Safe drinking water is one of the United Nations Millennium Development Goals—by 2015, the United Nations hopes to decrease the proportion of people without sustainable access to safe drinking water by 50 percent. SAFI filter aims at improving efficiency ,flexibility and has a dynamic design to reach households with the greatest need for clean, safe drinking water. SAFI is a swahili word meaning "clean" It's a collapsible filter that is designed to fit all water collecting objects and also it being detachable can be used on water sources such as taps and sinks among others. To increase access to clean water, SAFI team comprised of two interaction design students (Susan Oguya and Swatti Kashyap) with a background of entrepreneurship and industrial design teamed up to work and identify, adapt, and develop appropriate dynamic filter and business model to build a sustainable commercial market in household water treatment and storage for low-income consumers.
Clean Water 4 Africa
As Enactus Midlands State University and in partnership with Future waters Bulawayo we designed a machine that uses carbon filtration process to purify water. it costs US$850. It consists of a manual hand pump to reduce costs, aqua shield filter and granular activated carbon filter. We are looking for means to avail and increase production of such machines and probably modification of having the machine at a large scale and being powered by solar.
Water supply will see a 40% increase in demand in the coming decade and the topic of increasing the supply is at the heart of the issue. Agriculture uses 70% of the world's water and the water problem can be solved by disciplined agricultural techniques such as reduction of over irrigation, use of drip irrigation, sprinklers, fertilizers, Genetically Modified crops. Usage of better irrigation techniques will also boost the underground water levels. Along with these proper cold storage and transportation of agricultural produce is important as their loss should be seen as use of more water or more drop per crop. Other methods such as river linking, creating huge dams for water storage, treating sea water, bore wells are expensive and take a long time to implement.
Whatever the means (out of the varied means of getting water) employed in providing clean water and better sanitation in the African countries, the most important thing is education in ensuring the sustainability and maintenance of the structure. We propose an online educational community using mobile phones. This is imperative as a result of the population of mobile phones in the world, outnumbering the world’s population coupled with the positive and landmark achievements realized already in the use of mobile phones as a means of trade, agricultural market, payment of bills and what have you. We propose the use of a mobile app platform that works on both high end (smart phones) and low-end mobile phones. First there is need for physical installations in each community (especially in the rural areas as rural people tend to have higher believe in what they see or where they can easily go to and need to always see someone they can talk to) which will serve as information desk and help desk for each particular community. Then there is need for an initial public seminar (a three day seminar should be enough for each community) for everybody or at least a representative of each household. This is where the community members are registered with their mobile phone numbers and can download the mobile app, depending on their phone model. The community is further divided into groups for record purpose, maintenance task allocation purpose and for effective spread of information through words of mouth. Individuals can always go back to the physical installations later for any inquiry or any other help. Sanitation tips, general hygiene tips and tips on using the water and sanitation resources sustainably would then be sent to their mobile phones through SMS and voice messages (this does not require internet service). Also important updates and news from around the world and those pertaining to the local neighbouring communities can be received on their mobile phones. The program structures a way to make community members participate in construction and maintenance of the source of water through the groups. This way, the individuals feel a sense of responsibility towards protecting and using the resources sustainably. The app also involves a database that keeps the record of past achievement, analysis of future trend and possible future effects. Though clean water is very important for the health and sustainability of individuals. Rural dwellers are not willing to pay so they prefer getting water from open streams which are exposed to a lot of infections as they serve as source for animals and agriculture. A little amount of $10 can be charged per annum to keep the programme running (from call credit). Individuals who would love to volunteer more could and commercial activity could be charged a little above $10. Fixing this with the average number of people in each community in Africa, this money would be enough to cover for maintenance cost and running of the program.
Most local authorities in Africa are overwhelmed by improving water supply. Public Private Partnerships in water treatment plants will lift the burden on local authorities by assisting on supplying chemicals and rehabilitation of the plants. The major benefit of the partnership is to improve financial resources in water treatment.
Diarrhea and Cholera are the most Public Health problems related to Sanitation in Mwanza causing hundreds of death among children. Disease statistics indicates that 60-80% of the diseases requiring hospital attendance are those related to poor Sanitation. The Overall picture from the mapping survey indicates that most schools are Characterized by Non-Existent or insufficient water Supply, Sanitation and Hand Washing facilities; and in some other cases, facilities do exist but many are broken, unclean or unsafe. Without Water and Sanitation facilities, hygiene promotion and education in Schools is difficult and has minimal Impact. School-WASH Provides expertise and Interventions aimed at saving lives and reducing illness by improving access to healthy and safe water, adequate Sanitation and Improved Hygiene. This program works on long-term Prevention and control measures for improving health, reducing Poverty and improving Socio-Economic development as well responding to emergencies and out break of life threatening illness. Objectives of School WASH project: i/ To Influence communities to participate in planning, construction, use and maintenance of user friendly water, sanitation and hygiene facilities for school and communities ii/ To build human resources capacity for improved School Water, sanitation and hygiene service delivery which is gender friendly and accessible. Iii/ To provide conducive, accessible and inclusive environment for school children with special needs. Iv/ To improve hygiene practices among school children, their families and communities. v/ To improve water, sanitation and hygiene facilities for better health and well being for School and children Theory Of Change: Children are change agents. Schools are important links to reaching individual families families and communities. Children pass on their knowledge of hygiene behavior practice from schools to their families and thus influence the community. Hygiene Behavior is a function of many factors namely Availability of water supply, hygiene facilities, altitude and appropriate Knowledge. Knowledge on Hygiene is imparted to school children through existing school curriculum and health education provided by local health professionals. Behavior of school children may Not be possible to change if enabling factors such as water supply, and other elements of hygiene are inadequate or lacking.
Problem: Water pollution is a major challenge throughout the world. The challenge of water in Africa is linked to health, power, energy and the economy. The purification of water might help minimize the above mentioned challenges, giving us a second chance to build a better economy. Few people in the continent have little of no access to purified water and thus rely on the wells and dams for freshwater for domestic use. The use of un-purified water exposes people to a lot of health issues, as for farmers, they experience challenges associated with the growth and production of their crops. Thus materials for massive treatment are required in this case for everyone to have access to clean and safe water. Solution: Membranes and environmentally friendly chemicals may be used to purify water, targeting all contaminants in water such as microorganisms, organic pollutants and inorganic pollutants. The materials: Ag/TiO2/MCM-41  and PES/Ag/TiO2/MCM-41  may be used for water purification. Material  is a powder and thus will be deposited in ground water for the adsorption and removal of all contaminants including toxic microorganisms, organic pollutants (dyes, pesticides etc.) and inorganic pollutants (heavy metals, of interest). Material 2 is a membrane and will be used for the purification of water before released to the receiving watercourses from the industries and mines. All these materials incorporate the energy of the sun for water purification, through titanium dioxide for photocatalysis. The selected materials are of interest since they are environmentally friendly, commercially available, hydrothermally and mechanically stable, cheap, have anti-fouling and anti-microbial activities, and stable against corrosion. The future of pure, clean and safe water for all lies with these materials. Africans working together for a better tomorrow for Africa. Targeted pollutants: organic, inorganic and toxic microorganisms Application 1: The first material will be deposited in ground water (wells, ponds, dams etc.). Since we know that other areas only rely on these points for fresh water..., upon sedimentation it will thereafter adsorb and remove contaminants in water (This is a good idea if the catalyst is not to be recovered). Considering the fact of recovering the catalyst, big tanks which have pipes connected to the dams and ponds will be introduced..and the materials will be deposited in the tank and upon emptying of the tank the catalyst may be recovered. to ensure maximum purification, the second material will be placed at the taps to filter remaining contaminants. Application 2: The second material is targeted for application in the main sources of pollution (industries, mines etc). They may be applied independently for the filtration of water to remove pollutants before release to the receiving watercources, or we may have a system where there water first passes through a big tank which contains material 1 (for degradation of dyes since it requires time, maybe 12 hours) then pass through material 2 (membrane) which will filter any remaining carcinogenic contaminants. Both materials are suitable for commercial use, thus massive purification
We propose a circulation shower that saves 90% on water and energy. Families can shower endlessly with only a bucket of water. Our idea is to make an Africa-proof version of the circulation shower - a proven concept. This idea has already been deployed in the Netherlands and is ready to be deployed quickly on a large scale. By making circulation showers available to all families, schools and other public institutions, children can go to school clean, drinking water and groundwater will be conserved and only very little waste water is produced. Our new shower filters and purifies the water 30 times per minute. It is engineered with industrial components and stainless steel guaranteeing a long lifetime: Suitable for harsh environments. Lasts 20 years, maintenance-free. Extremely affordable: basic systems can be engineered for a few hundred dollars. Suitable for community usage. The circulation shower can be fully powered by solar panels and requires only a bucket of water per session, making it a fully functional stand-alone sanitation system. So how do we keep it clean over the long lifespan? We believe that a self-cleansing system should be in place, and that any maintenance should be extremely low-tech and layman proof. We have the following solutions in place: - To stop blood, skin cells, mud and the like: we have an extremely simple and cheap membrane, which prevents these elements from entering the system. - The membrane will never stop soap and urine getting IN to the system, but CAN force it out after every shower. This because the piping and pump are fully drained by gravity. Exiting the system, the water will purge the membrane by default, leaving it clean for the next person. - The inner workings (pipe, pump and shower head) can be easily rinsed with eco-friendly detergents. Lemon juice with water cycling for a while should do most of the jobs. - The pipes can be nano-coated to prevent the build-up of any unwanted substance over time. - The membrane is detachable from the pipe with a simple magnet. So the part that does most of the filtering can be either cheaply replaced or soaked in eco-friendly detergent for a night. An animation of the existing and proven concept can be viewed here: http://youtu.be/pNgMhooKGuU Africa needs this. Let's make it happen.
Lake Victoria is the largest fresh water source in the Africa. In the western part of Kenya, it is also the largest free water source and also in the whole of Kenya. Along its shores is majorly occupied by fishermen, which means it is not only a water source but also a main source of income to thousands of people in Kenya. However, there lies a very big risk and exists a series of water borne diseases in this region. There is a very high rate of pollution into this lake; 1. There is no system for waste and sewage. This is caused by one major problem of lack of toilets in most of the parts of the Western Kenya. As a result, the human call for nature is done in the bushes and open places. This also happens in some of the regions where the rivers that channel water into the lake pass. This aspect has largely been contributed to by the fact that there is a very high level of illiteracy this region and the mixture of people from different regions including Uganda and Tanzania who move into these regions looking for sources of income. 2. There is a very big lack of knowledge about waste disposal, management and reuse. As a result there exists a problem of poor waste disposal which finally through different forms find their ways into the lake contributing to a very high rate of pollution. Through the above two different forms of pollution, when there is rain, all these human wastes and solid wastes find their ways back into the lake polluting the water that is used by millions of habitants around the Lake Victoria. 3. The other great problem that exists here and affects a very high percentage of purity of the lake although is being ignored is burying bodies of the dead in tombs whose insides are not cemented. During decomposition and rainy seasons, all the bacteria pollute the underground water which finds its way into the lakes finally polluting the water largely. All these with all the biodegradable wastes that goes into the lake creates an oxygen depleting effect that contributes to having less oxygen in the water each day. This with other chemical pollution has also contributed to the death of many fish in the lake hence making the water unsafe. This water furthermore is used by the residents untreated. 4. A very common dangerous tradition especially amongst the fishermen here is responding to the call of nature in the water especially when they are fishing. This happens in large volumes and so frequently and all the time since people do fishing 24 hours of a day. This pollutes the lake water so much 5. A very common culture here is people bathing and doing laundry inside the lake. This act does not only pollute the water but also has led to spread of diseases greatly. Given this need and real necessity for a solution to this environment, my idea is to come up with four related initiatives that will educate, prevent and improve knowledge, purity of water and the sanitation. 1. Given the high rate of illiteracy in this region, BOILING WATER FOR DRINKING AND DOMESTIC USE is a very economic, literacy-unnecessary and easy method that we can mobilize and educate the communities to adopt towards creating a healthy future. My initiative will organize home-to-home program teaching people this method that kills water germs at a temperature of around 70°C. Indeed, with wood fuel, this requires less than 10 minutes to boil. Given the availability and traditional use of wood fuel, what my initiative will stress on is the sanitation of the homesteads. With this method, we do not need to spend even a single penny to make water healthy for drinking. With no chemicals added, I believe it is the best method to purify water. 2. To prevent widespread of pollution and improve the general sanitation of this region that hosts more than 30 million residents and supports one of densest and poorest rural populations in the world (Global International Waters Assessment,2006), my initiative is to seek support to build toilets in this region where very few exist. This is meant to be done systematically one region after another beginning with the Bondo District in Kenya. To provide and improve sustainability and help our population save on costs, we are looking forward to building special mechanized toilets connected to a biodigestor between each three to five households. This is further meant to save on wood fuel, charcoal and paraffin that in one way or another always have great financial effects to the family or environmental effects to the lake and the future of the world. With this furthermore, the families are not going to struggle boiling the water for drinking and household use. The built toilets are also meant to serve as bathrooms to totally avoid the issue of bathing and doing laundry inside the lake. 3. To avoid the rapid pollution and also improve on the sanitation of our fishermen, my initiative will improvise a portable small toilet which uses ash and saw dust to kill the micro bacteria and remove the smell to be carried while going fishing and be used instead of the water. 4. My initiative, with support from EARTH University, Costa Rica is will also educate the communities on how to safely dispose, recycle and reuse solid wastes without letting them pollute our waters and environment. This will not only help reduce pollution but also help create sources of income to the residents Video source Youtub https://www.youtube.com/watch?v=MYTEI_Wd13k&feature=player_detailpage
