Constructed wetlands are treatment systems that use natural processes involving wetland vegetation, soils, and their associated microbial assemblages to improve water quality.
The primary renewable source of freshwater is continental rainfall, which generates a global supply of 40 000–45 000 km3 per year. This more or less constant water supply must support the entire world population, which is steadily increasing by roughly 85 million per year. Thus, the availability of freshwater per capita is decreasing rapidly. About 80 countries and regions, representing 40% of the world’s population, are experiencing water stress, and about 30 countries of these are in OIC regions.
Whereas the mandate and mission of INWRDAM is to foster closer cooperation among all the countries of the Organization of Islamic Cooperation (OIC) in the field of development and management of water resources and establish linkages with the international water community and in pursuit of this mission, it seeks to generate ideas and policy directions through intensive dialogue, studies and research on a continued basis.
INWRDAM and in cooperation with The International Union for Conservation of Nature/ Regional Office for West Asia (IUCN-ROWA), implemented three wastewater treatment units at household level based on INWRDAM developed designs for natural treatment processes in Balqa Governorate in the villages of Allan, Jallad and Um Alamad.
