Assainissement solide et liquide de Djibouti ville : Un programme intégré

Mardi, 24 Janvier 2012 17:20

Le palace Kempinski a abrité hier, lundi 23 janvier 2012, le lancement officiel du programme intégré d'assainissement solide et liquide pour le développement durable de la ville de Djibouti. Plusieurs personnalités djiboutiennes et européennes ont honoré la cérémonie de leur présence. Citons le ministre de l’Economie et des Finances, M Ilyas Moussa Dawaleh, le ministre délégué au Budget, M Amareh Ali Saïd, la secrétaire d’Etat à la Solidarité Nationale, Mme Zahra Youssouf Kayad, l’ambassadeur de l’Union Européenne, M Nicolas Delcroix. Notons la participation d’un bon nombre de responsables issus des rangs de différents acteurs institutionnels concernés au déroulement de la cérémonie de lancement de ce chantier d’envergure. De quoi s’agit-il au juste ?

De manière concrète, une série de quatre contrats de travaux et de supervision portant sur l'assainissement liquide et solide viennent d'être signés entre le Gouvernement djiboutien et l'Union européenne. La contribution totale de l'UE s'élève à 17, 7 millions d’euros, soit plus de quatre milliards de nos francs.

Ce programme prévoit la création et la mise en service à l'été 2012 d'un centre d'assainissement à Douda, au sud de Djibouti ville. Lequel comprend deux volets d'infrastructures.

Pour l’assainissement liquide, l'objectif est la conception et la réalisation des travaux de construction et d'exploitation d'une nouvelle station d’épuration (STEP) d’assainissement liquide de la ville de Djibouti et touchera près de 40.000 habitants. Celle-ci produira à plein rendement près de 3.700 m³ d'eau d'une grande qualité, soit l’équivalent de 10% de la production d'eau actuelle sur Djibouti).

En matière d'assainissement solide, ce nouveau centre d'enfouissement technique (CET) aura un volume total jusqu'à 500.000 m³, pour une période d'exploitation estimée entre 5 et 9 ans. Ces travaux comprendront la construction d'une dalle de tri et de deux socles de stockage en bitume pour les déchets recyclables non fermentescibles et pour la production de compost.

Cet important projet d'assainissement a pour objectif premier l'amélioration de la qualité de vie des habitants de Djibouti ville, soit près de 65% de la population de Djibouti vit actuellement dans la capitale. Il s'agit d'un programme de développement durable qui constituera un vecteur économique, social et écologique. Il positionnera Djibouti au travers de Douda comme un des premiers centres d'excellence des systèmes modernes de recyclage et de compostage des déchets organiques d'origine liquide et solide, en ligne avec les objectifs de l'Initiative Nationale de Développement Social (INDS) de Djibouti, des Objectifs du Millénaire pour le Développement (OMD) et de l'agenda de RIO.

En amont, le projet se traduira concrètement par la mise en place de filières de recyclage à caractère socio-économique. En aval, il donnera lieu à un développement agricole social au sein des communautés péri-urbaines de Douda (250-400 hectares) et à la protection de la biodiversité (800 hectares) constituant le point de départ de la Grande Muraille Verte sub-sahélienne. Ce projet touche donc à de multiples facettes de la vie des djiboutiens : amélioration de la santé publique, de la protection de l'environnement et de l'éco-tourisme, création d'espaces verts ainsi que d'une agriculture structurée ayant une forte composante associative et féminine, en vue d'assurer un impact rapide et concret sur la réduction de la pauvreté. La sensibilisation, éducation et formations seront inscrits à chaque niveau de projet.

Avec le gouvernement et les pouvoirs publics, de nombreux partenaires tels que l'OVD, l'ONEAD, le CERD, l'ADDS, l'AFD et la JICA le refuge DECAN témoignent de l'engagement et de l'importance du projet. Cela suppose une implication forte et permanente des simples citoyens, des acteurs du tissu associatif, des opérateurs économiques de la place et des autorités compétentes. Voilà une condition incontournable dont la satisfaction devrait conforter la démarche intégrée de ce programme d’assainissement qui place réellement le développement durable au cœur des actions et des politiques du gouvernement djiboutien et des partenaires au développement.

Liquid and solid sanitation for Djibouti City

For a modern recycling and composting of organic waste

The European Union has funded a major program of sanitation in the city of Djibouti to the tune of 4 billion FDJ. This important program that includes a series of four works contracts and supervision concerns the sewerage and solid in the city of Djibouti.

The European Union and the Republic of Djibouti signed a series of four contracts yet on solid and liquid sanitation in the city of Djibouti, worth £ 17.7 million over four billion FDJ.

The program, which provides among others the creation and commissioning in summer 2012 a consolidation center in Douda, south of Djibouti has two components.

Initially, it comes to the design and implementation of construction and commissioning of liquid sewerage infrastructure in the city of Djibouti, and the operation of new wastewater treatment plant (WWTP ).

It will produce at full capacity around 4,000 m3 of water of high quality (nearly 10% of the currently produced water in Djibouti). Which will include irrigation of 400 hectares of crops and the development of an ecological zone rehabilitation and protection of biodiversity.

The putting into operation of this first phase is scheduled for May 2013. The second part concerns meanwhile, sanitation solid. This new Center Landfill (CET) will have a total volume of 500,000 m3 usable for a period of exploitation estimated between 5 and 6 years.

These works include construction of a slab of sorting and storage of two bases in asphalt for recycling in unfermented and targets for the production of compost.

This major remediation project's primary goal, improving the quality of life for people in Djibouti city.

The country at a high rate of urbanization. Indeed, over 65% of the population of Djibouti is currently living in the capital, which implies constantly improve infrastructure.

This project touches on many facets of the lives of Djibouti which among other things, improving public health, environmental protection and eco-tourism, the creation of green spaces and an agriculture structured with a strong associative and female, to ensure a quick and concrete impact on poverty reduction.

This is according to experts of a program of sustainable and social development. It will set Djibouti through Douda the leading center of excellence of modern recycling and composting of organic wastes original liquid and solid.

Particularly interesting synergies will be developed on the processing and recycling of solid components (composted organic matter) and liquid (water production and sludge enriched).

The concept of a similar project on Balbala is being finalized between the EU and the French Development Agency, which will support channels for collecting, sorting and composting.

Djibouti inaugurates its first wastewater treatment plant wastewater

DJIBOUTI ( Xinhua) - Djibouti President Ismail Omar Guelleh Saturday inaugurated the first wastewater treatment station of Djibouti .

The new wastewater treatment plant (WWTP ), funded to the tune of 13 million euros by the European Union ( EU) has two pumping stations and two pressure lines . It will also be complemented by the installation of a primary collector with an additional EU funding of € 5.5 million. According to the Djibouti Ministry of Water , commissioning will result in a reduction in health risks and better preservation of marine ecosystems by preventing the discharge of sewage into the sea

The WWTP should produce a daily volume of 3,700 m³ of treated water to be used for agricultural , ecological and biodiversity protection .

The work will facilitate the recovery of approximately 800 acres of the original flora and fauna on the coast. A portion of the treated water will be directed to the maintenance of mangrove areas . With as ultimate goal of enabling initiatives eco-tourism on the outskirts of the Djiboutian capital. In addition to their financial contribution , the EU and the African Development Bank (ADB) supported the Djibouti authorities to find the necessary expertise for the implementation of this project is to support the efforts in order better maintain sanitation networks in Djibouti.

In Djibouti, the new wastewater treatment plant saves resources by producing purified water ready for re-use

On the East coast of Africa, between Eritrea, Ethiopia and Somalia, the Republic of Djibouti covers a land area of 23,000 km2, and is home to just over 800,000 people, two-thirds of whom live in its capital city. The hot, arid climate of Djibouti makes this one of the world's most impoverished countries in terms of water resources, with the majority of supplies abstracted from aquifers. Confronted by acute water stress aggravated by demographic growth and climate change, ONEAD (the Djibouti National Water and Sanitation Office) has made water industry development one of its national priorities.

The constant decline in rainfall levels makes it crucial to find other sources of water supply and to inform the population of how to use water economically and sustainability. Wastewater purification for re-use is making an important contribution to overall water management in Djibouti..

Reusing purified wastewater for irrigation

This is the background against which Stereau and Colas Djibouti have joined forces to build the new Douda wastewater treatment plant to serve Djibouti City. The 40,000 population equivalent capacity of this plant officially opened in March this year could eventually be doubled in response to three objectives that are keys to the local population and their environment :

• improving quality-of-life and health safety for the capital's residents
• protecting coastal waters, which until now have been polluted by discharges of wastewater from Djibouti
• saving groundwater resources by reusing treated wastewater

The purified wastewater will be used for tree cultivation, the agricultural irrigation of around 400 hectares of arable land (nearly half of the country's water resources are currently used for this purpose) and the development of an ecology zone to protect biodiversity. The residual sludge from the purification process will be used as fertiliser to improve agricultural land.

As plant operator, Stereau is contributing all its expertise in wastewater treatment to this project. A tertiary processing stage accompanied by disinfection using chlorine produced on-site by an electrochlorination process delivers a level of treated water quality that exceeds WHO standards for wastewater re-use.

This facility and the processes it uses provide a perfect illustration of how today's water technology solutions can respond effectively to water poverty.

Djibouti : the new wastewater treatment plant promotes the re-use of treated wastewater


Stereau has responded to the problem of water stress by working alongside Colas Djibouti on the construction of a new wastewater treatment plant in Douda; a plant designed to promote the re-use of treated wastewater.

Designed and constructed by the consortium of Stereau and Colas Djibouti (the concession holder), the new Douda wastewater treatment plant in Djibouti was officially opened on 22 March this year.

Completed on schedule in just 16 months, the 40,000 population equivalent capacity of this plant could eventually be doubled in response to demand from local authorities to protect water resources and strengthen Djibouti in its ability to combat climate change. Stereau, the Saur Group’s engineering company, will operate the plant for the next two years as it transfers skills to local employees
