About fifty small dams were constructed in the Jabla Al-Akhdar, which is a mountainous remote area in Oman. Water is supplied from these dams to the villages through elevation streaming by gravity or using submerged pumps with generators. It is used for livestock and agriculture.
Multi-stage filtration is a water treatment suitable for small communities (up to 30.000 inhabitants) that has low maintenance and opration requierements. It uses natural processes to improve phisico-chemical and micro-biological parametres so at the end disinfection is just the last barrier to protect water until it reach the final users.
The Water Project Toolkit addresses the sustainable development of the water sector and contributes to translating the international development policies on freshwater resources management into actual development cooperation activities. The Water Project Toolkit is intended to be used by sector stakeholders such as governments, private sector, civil society, development partners, Universities and other training institutions, international organisations and all other practitioners involved in the water sector.
Trans-boundary Water for Biodiversity and Human Health in the Mara River Basin (TWB-MRB) in Kenya and Tanzania
The overarching goal of the TWB-MRB Project is to implement a coordinated and highly participatory project to improve water resource management in ways that reduce and mitigate threats to biodiversity in the Mara River Basin and Mara-Serengeti Ecoregion, while enhancing the health and livelihoods of communities living in the basin.
EARTH OBSERVATION FOR GROUND WATER EXPLORATION, MANAGEMENT, VULNERABILITY AND PROTECTION: THE GOTHAA APPROACH
The GOTHAA (Geologie Observation de la Terre pour l’analyse d’aquifère) as developped since the year 2000 to support exploration of new ground water resources using earth observation techniques. The approach has been tested in various climatic, geologic, land use contexts in Argentina, Egypt, France, Indonesia, Saudi Arabia, Libya.
The report shows the full magnitude of the benefits of water services. The provision of water supply, sanitation and wastewater services generates substantial benefits for public health, the economy and the environment. Finally, protecting water resources from pollution and managing water supply and demand in a sustainable manner can deliver clear and sizeable benefits for both investors in the services and end water users.
Water Use Master Plan (WUMP) – an approach to participatory and inclusive planning for integrated water resources management
The Water Use Master Plan is a planning process applying an Integrated Water Resources Management (IWRM) approach. It is a response to the widely felt need for an instrument for local actors to address water management issues properly. The WUMP process ensures identification of available water resources and water needs at the level of a Village Development Committee (VDC), the lowest administrative unit in Nepal (‘commune’). Moreover, it provides an overview about available and needed water-related infrastructure. This enables planning/prioritizing the use of available water resources (drinking water, irrigation, water for nature and other uses) and serves as a basis for sound investments in the water sector.
The project consists of modular and semi-mobile photovoltaic solar cells power supply system with a capacity of 45 K Watt/hr working during the day hours only to reduce the cost of energy storage. The generated electrify is used to operate a high efficient RO desalination plant for brackish groundwater treatment. The capacity of each RO unit is 5 m3/hr with a recovery ratio of 60%. The system is provided with an ultraviolet filtration and disinfection system. The raw water is abstracted from a groundwater with a submersible pump operated by the solar energy also. Various alternatives and options for brine water discharge were evaluated and it was found that the optimal solution is use evaporative lake. However and some areas where the raw water salinity is less than 10,000 the produced brine water can be used for irrigating native desert plant species (salt tolerant species). It has been found that this system is feasible and the consumption of the energy ranges between 3.0 to 5.0 Kwatt/m3.
The State of Qatar has embarked on a programme, called “QATAR NATIONAL FOOD SECURITY PROGRAMME (QNFSP)”, for the development of indigenous agriculture production to improve food security for the population of the State. Any increased agricultural development will provoke a challenge to the water reserves. With depleting natural water reserves, and to meet agriculture’s voracious appetite for water, such a large quantity of water for the QNFSP programme has to be from Sea Water Desalination.
The State of Qatar has embarked on a programme, called “QATAR NATIONAL FOOD SECURITY PROGRAMME (QNFSP)”, by linking Solar energy, Seaawater Desalination and Agriculture development to enhance food security and simultaneously augmenting the water security will allow Qatar to establish a global reference project for “green” agriculture policy for arid states worldwide.
KAHRAMAA has contracted for Engineering and Consultancy services to provide the required consultancy services to support and assist in its tasks for the Qatar National Food Security Program (QNFSP) effort to assure the provision of the required amount of water and electricity for agriculture purposes in Qatar.
