The Access to Essential Services Award, for a sum of €50,000 is awarded to a non-profit organisation as a reward for its innovation. It aims at creating a bridge between applied research and operational development projects. The objective is to promote the innovations to the greatest number of people so that then they may be used by professionals in the water, sanitation and waste management sectors in developing countries. The innovations, applicable in the field, can be technical, organisational, financial or social, and may concern tools for spreading information and knowledge.

"From a deserted landscape to a reforested landscape"

Water collection to strengthen access to drinking water

This project uses the new technology of CloudFishers©, which collects fog water, stores it and then filters it to supply arid hamlets located outside the drinking water system, in the Anti-Atlas territories, southwestern Morocco. The project includes the training of inhabitants and the sharing of know-how in adduction and installation of fog collection nets, at the national and international levels. Thanks to this system, nearly 1,200 people already have access to water, and daily consumption per person has increased from 7 to 26 liters between 2011 and 2016.

"Cajouvalor" and "Interk'eau"

Developing a technology to recovery energy from cashew nut shells. 

The CAJOUVALOR project by Rongead, in partnership with the Cefrepade, had the objective of developing a technology to recovery energy from cashew nut shells. This project consequently aims to recovery energy from a waste, the cashew nut, via the development of a pyrolysis reactor known as the “H2CP” (High Calorific Cashew Pyrolyser). The system permits waste generated by cashew nut shelling to be transformed into two types of fuel: pyrolysis gases which namely power a boiler and Biochar for domestic or professional use, distributed in the form of blocks to local populations in order to replace wood charcoal (originating from unmanaged forests threatened by deforestation).

The CAJOUVALOR project has enabled the development of other agro-industrial waste recovery sectors in Burkina Faso: a partnership with L'Occitane has been signed for the recycling of shea cakes.
Given the success of CAJOUVALOR in Ivory Coast, a new project, "Agrovalor", was launched, combining the revaluation of cashew and shea butter waste. In 2018, some thirty CAJOUVALOR ovens are being built in West Africa.

"Interk'eau" sustainably improving access to drinking water and sanitation in Niger

“INTERK’EAU” PROJECT BY EAU VIVE, IN NIGER The global objective of InterK’Eau is to lastingly improve access to drinking water and sanitation services for 400 000 inhabitants in the canton of Kornaka in the south of Niger, whilst innovating via the introduction of an inter-communal sustainable water supply service. Its specific objectives are therefore complementary: to reinforce the capacities of elected representatives, administrations, water technicians and users whilst simultaneously planning concrete realisations which permit everybody concerned to fulfil their responsibilities in terms of water point management

The Eau Vive project "Interk'eau" is renewed for a second phase that will begin in July 2019. Since the end of the first phase, cooperation with the city of Kornaka has been strengthened, the sensitization of elected officials and exchanges between the different communes of the canton continue.

"Biogas installation in Durame prison, Ethiopia"

A digestion tank installed to produce biogas from wastewater and organic waste.

A digester producing biogas from latrine’s and organic waste has been implemented in Durame’s prison, in Ethiopia. This project was successful. Indeed, on the one hand, it has improved the living conditions and health of the prisoners, the prison staff and the surrounding inhabitants. On the other hand, it has reduced the environmental impact of the prison (use of renewable energy, reduction of deforestation). In addition, the project has also had a positive economic impact, by reducing the energy cost, self-producing of organic fertilizers, and shrinking staff turnover.

"Mothers Club in the Savannah region of Togo" and "Semi-collective sanitation in Africa"

Good practice in water, hygiene and sanitation

The Mothers' Clubs act as permanent hubs and focal points within their community for ensuring awareness of the importance of sanitation and waste management and for raising awareness of suitable hygiene practice. Women, by virtue of their place within the community, represent a key inter-generational pivot for raising awareness amongst their peers, in relation to community health, the management of water structures and good practices relating to water storage, hygiene and the general sanitation of the village. The method developed by the Mothers’ Clubs expanded to 24 villages in Chad, affecting 775 women.

"LESEAU" new prototype for better access to water

The Grand Prize for the second SUEZ ENVIRONNEMENT Foundation Water for All Competition was awarded for a technical innovation developed by the Yaoundé Higher Polytechnic School of Engineering (ENSPY) in Cameroon.
The LESEAU project targets populations with no access to the public water supply or with only intermittent access due to frequent interruptions in supply.
Pilots have been under way since 2005 and the results have been very promising in terms of community health, especially for children under five years of age.
In 2009, the pilot phase led to the implementation of a new prototype fitted with a rustic clay filter incorporating bactericidal agents such as colloidal silver. Over and above the health aspects of this low-cost household solution, Dr Ngnikam’s team intends to use the project to create jobs and consolidate the skills of local community members.

CAWST offers a training method built around nine major topics.

In 2010, the Jury awarded the Special Prize to the Centre for Affordable Water and Sanitation Technology (CAWST), founded in 2001 by Camille Dow Baker, for the originality of its project.
CAWST is a Canadian engineering organisation that aims to help communities find and implement locally appropriate technical and managerial solutions relating to water and sanitation. CAWST offers a training method built around nine major topics, such as water treatment, low-cost sanitation and rainwater harvesting in disadvantaged regions.
To disseminate ideas and transfer skills, CAWST has a policy of forming partnerships with agencies, so-called WET centres, providing services similar to its own in the local area. The 2010 Special Prize will enable CAWST to consolidate and expand its mission further afield.

(CWSS) a running water supply of 2iE

In 2009, the Jury of the SUEZ ENVIRONNEMENT Foundation’s Water for All Competition awarded the prize to the International Institute for Water and Environmental Engineering (2iE) based in Ouagadougou, Burkina-Faso.
Collective Water Supply Stations (CWSS) provide a supply of running water from taps installed in a public space and equipped with metering facilities.
As an alternative to individual connections and street fountains, the project should improve the water supply service, providing a sustainable supply of water at reasonable cost to disadvantaged populations in urban areas in Africa. Project trials have been under way since 2000 in a number of small towns in Burkina Faso and Mali, and the results have been very good.

"Barefoot" skills enhancement

In 2009, the Special Prize was awarded to the Barefoot College, founded in 1972 by Sanjit Bunker Roy in the state of Rajasthan, India. The Jury wished to reward the originality of the project and the team’s perseverance.
Taking advantage of informal know-how and local experience, the Barefoot College trains villagers, and in particular women, those combating illiteracy and those most disadvantaged, in practical matters relating to fields such as water, energy and health.
This approach to the dissemination of know-how and capacity-building has spread to other states in India and to Afghanistan, as well as to a number of African countries.
