Problem: What problem is this initiative trying to address?

Unsafe drinking water, inadequate availability of water for hygiene, and lack of access to sanitation together contribute to about 88 % of deaths from diarrheal diseases. More than 2.6 Billion people still do not have access to proper sanitation. Each year, 1.5 million children under the age of five years die due to diarrhea caused by unsanitary conditions and poor hygiene. The absence of adequate sanitation and wastewater treatment plant has a serious impact on health and social development, especially for children.

Solution Summary: What is the proposed solution? What do you see as its most promising aspects for creating shared value?

We developed a novel innovative, low cost and, efficient and ecological wastewater treatment technology called ‘Multi soil layering (MSL) technology’. MSL technology is an innovative wastewater treatment technology based on water filtration using low cost and available materials in rural areas. The environmental cleanup capability of soil is maximized in our MSL systems, while avoiding many problems encountered in the existing wastewater treatment technologies. Our innovative technology was tested, optimized and proved as an efficient wastewater treatment method in laboratory scale, in a reel application in rural village and in a full wastewater treatment plant in Marrakech. Our technology was patented since January 2017 (MA 37803 B1, Cl. Internationale: B01D 25/02; C02F 3/02; C02F 1/00. 2017). Our solution provides a new low cost and efficient method for domestic wastewater treatment and reuse in: 1- Rural communities, 2- Villages 3- Decentralized institutes (hotels, schools...)

Impact: What is the impact of the work to date? Specify both the social and the environmental impact of your work

- Ensures access to good sanitation service for rural and poor population, - Reduction the effects of wastewater reject (Water diseases), - Protection of water resources (groundwater and surface water), -The beneficiaries (3 villages, 5000 inhabitants) replaced using freshwater for irrigation by the treated wastewater, thus saving fresh water for domestic uses and reduce the water bills, - The development of agriculture sector by reusing treated wastewater in irrigation, -Treated wastewater is being utilized for the irrigation of economic plants such as olive and grapes, - Minimize the use of potable water in irrigation, - Limiting the use of chemical fertilizers in agriculture, - Improving the life quality of rural population, - Offers job opportunities in agriculture, - Awareness raising on the preservation of the environment and enhance the public awareness levels among inhabitants, - Promote education of children in rural schools by providing a safe sanitation service.

Financial sustainability plan: How is this initiative financially supported? How will you ensure its financial sustainability long-term?

Grant: Our social Startup 'WATECH' was funded by a grant of 23 000 USD from the National Center for Scientific and Technical Research (Rabat, Morocco) and the Moroccan Incubation & Spin-off Network (Rabat, Morocco). Revenues: The estimated revenue is more than 300 000 $ in the third years of operation. -First year (2016): 43 858 USD. -Second year (2017): 158 120 USD. -Third year (2018): 315 420 USD.

Unique value proposition: What makes your initiative innovative? How does your project differ from other organizations working in the same field?

-The investment and operational costs of our innovative solution are very low compared to the existant technologies -Small area demand resulting from the their high hydraulic capacity -Simple maintenance; no special competence was needed to operate the Multi-Soil-Layering technology -Minimum sludge production -No energy requirement for operation -The effectiveness of MSL technology to treat wastewater is climate, season and temperature fluctuations independent -Long effective life:20 years

Founding story: Share a story about the "Aha!" moment that sparked the beginning of this initiative.

From Lab to a Social Entreprise: During my PhD research, I developped an new wastewater treatment technology called: Multi Soil Layering System. This method has been successfully tested for domestic wastewater treatments in a laboratory scale at the National Center for Research and Study on Water and Energy (Morocco). A recent experiment has been conducted in 2017 at Talat Merghen village (Marrakech), to treat domestic wastewater from 96 households (500 inhabitants). The obtained results confirmed that MSL technology was very efficient to treat rural domestic wastewater. This experiment present the first wastewater treatment plant using our MSL technology in Morocco and it may be considered a recent technology in comparison with other MENA and African countries. Due to the number of demand of our innovative solution from rural communities, we created a this new entreprise 'WATECH'.
