Waterborne diseases are the leading cause of child mortality and cause stress and added expenses for families and government-run healthcare centers. Though there are water filters on the Tanzanian market, they have some major limitations. Locally-made filters do not safely filter drinking water, while higher-quality filters made abroad are difficult for local customers to maintain and repair.
These filters are also not customized to local environments and are not able to combat all of these issues; this becomes a problem because there are places where the water contains excessive fluoride or heavy metals and is turbid. In addition, purification systems are often expensive and local people cannot afford to purchase an entire one, though they can afford to purchase drinking water if it is cheap and easily available within their community.
Gongali has created an innovative water filter that is adapted to filtering out the types of contamination found in local communities in Tanzania. They have established water stations in communities that are run by local entrepreneurs from the community. Gongali gives them high-quality water filters for free and the entrepreneurs pay about 50 US cents per day to use the filter. They do training for their entrepreneurs and also provide them with informative literature on filters.
These entrepreneurs then sell water at a low cost, about five times cheaper than bottled water. Households can also purchase the filters for about $150. After filtering 800 liters, the filters need to be cleaned or replaced, and it costs about $5 to do so. If the entrepreneur wants to end their business, Gongali reclaims the filter.
Gongali’s water filter is locally made and takes into account the specific needs of the local community. Gongali develops customized products for their geographical area, and they innovate specific materials that are part of the integrated filter.

Why Do we need Hydraids (slow-sand filter) in Nanofilter?
Nanofilter*TM is a complete water purification system designed by integrating nanomaterials into the slow-sand water filters. It is an integrated filter based on APPROPRIATE TECHNOLOGY with three main components:
Slow-sand-filter (Eg.Hydraid, pail, Concrete BSF) for removal of water turbidity, and up to 97% removal of micro-organisms: bacteria, virus, and protozoa.
Nanomaterials – This is our “Trademarked” innovation published in 33 articles and Patented – for removal of harmful chemicals and complete disinfection without the need of further treatment (no chemical treatment, UV, etc).
0.1 Micron Hollow Fibre Membrane for quality assurance
What is/Who are the Global Sustainable Partnership (GSP)?
Global Sustainable Partnerships (GSP) is a 501(c) 3 American Charity that was established in 2010 by Kimberly L. Fogg and Mary Barth. Their partnership with GONGALI MODEL is for providing clean and safe drinking water to children in Tanzanian Schools. For details please consider their Website: gspartnerships.org
AFRICA PRIZE FOR ENGINEERING INNOVATION
The Africa Prize for Engineering Innovation aims to stimulate, celebrate and reward innovation and entrepreneurship in sub-Saharan Africa. The Africa Prize encourages ambitious and talented sub-Saharan African engineers from all disciplines to apply their skills to develop scalable solutions to local challenges, highlighting the importance of engineering as an enabler of improved quality of life and economic development. Crucial commercialization support will be awarded to a shortlist of innovative applicants through a six month period of training and mentoring. Following this period of mentorship, finalists will be invited to present at an event held in Africa and a winner will be selected to receive Pound 25,000.
Engineers from sub-Saharan Africa and from all engineering disciplines who have developed innovations that can provide scalable solutions to local challenges are eligible. The Africa Prize is generously supported by The Shell Centenary Scholarship Fund, Consolidated Contractors Company, ConocoPhillips and the Mo Ibrahim Foundation.
WE ARE LOOKING FOR PARTNERS WHO CAN WORK WITH US FOR THIS PROJECT:
Mesoporous Silica-base BioSand Filters (MPS-based BSF) for CLEAN SAFE DRINKING WATER. Also we have many ideas based on NANOTECHNOLOGY – removal of heavy metals and arsenic poisoning, business ventures for local communities, and policy change to save many people’s lives
1. How “Global” is the problem?
We are addressing the lack of clean safe drinking water that affects 1.2 Billion people worldwide. It was reported that every 20 seconds a child dies due to waterborne diseases (WHO). According to WHO/UNICEF 2012 report, 94% of the 187 Million people in the world who relay on surface water for drinking are the rural inhabitants in Sub-Saharan Africa.
2. Our Research Idea
We want to remove 100% of disease-causing microorganisms (including bacteria) from drinking water and “therefore” eliminate waterborne diseases in developing countries using Inexpensive Mesoporous Silica-based BioSand Filters (MPS-based BSF).
3. Expected Impact!
If combined with health education/sanitation and promotion, the use of MPS-based BSF will “eradicate” the waterborne diseases in developing countries. It adds “QUALITY ASSURANCE” to drinking water since at present the BioSand Filters are able to remove only 93 – 97% of bacteria (E.Coli) and might be a reason why BSF technology is not widely accepted and waterborne diseases continue to thrive.
4. Innovativeness of our idea
Mesoporous silica is one of the innovative materials promising to be competitive water filters that are not yet introduced into the market. It has superior properties and can be a perfect substitute for sand that is conventionally used in BSF. With wider pore size from 2 – 50 nm and larger surface area from 100 – 800 m2/g, mesoporous silica is expected to remove 100% of all contaminants, including bacteria. Mesoporous silica is inexpensive and harmless in human body and environment. When used as a substitute for sand, it overcomes all limitations of conventional water filtration technologies such as BSF, Chlorination, Boiling, and UV Treatment.This innovative technology can be commercialized
5. Experimental plan
The study comprises households living in a Village called Gongali in Karatu District, Tanzania. This village has conditions typical of much of rural Tanzanian communities and suitable for this pilot project. Households deemed at high-risk for water-borne diseases through drinking tap water will be identified and recruited…….
Concrete MPS-based BSF design will be used in this study (0.95 m tall, 36 cm diameter, 2.5 cm wall thickness) (Mol & Fewster 2007)……and 10 cm of mesoporous silica…….

6. How does our idea integrate scientific/technological, social and business innovation
Incorporated into this innovation is the training of Post-graduated University students and Village Water Management Committee (VWMC) so that the water monitoring process could be continued in the future. Participation of University students in this project will reinforce a link between academia, industry, and society; this is currently lacking in African Universities. Besides enhancing better health for children (who mostly suffer from diarrhea), and encouraging women participation, this study will also result in the establishment of business venture for this product and consequently benefit all parties involved. The results will be disseminated through publication, conference & exhibitions
