The Centre for Alternative Wastewater Treatment (CAWT) is proposing to develop a training program aimed at transferring knowledge to local agencies/organizations overseeing the implementation of wetland technologies and other appropriate treatment technologies devoted to providing increased access to wastewater treatment and hence increased sanitation. This work would be developed to address local conditions including both the physical and human resources for that region. The intent is to develop the capacity within the region for the implementation, operation and monitoring of technologies dedicated to the treatment of human sewage. The aim is to provide greater treatment of human sewage and by doing so to provide increased protection to local drinking water supplies.

The present proposal suggest a “tree model” for  conservation of urban wetlands by fair stakeholder involvements. The tree is composed of root system, stem and branches. 
Root : The central government which act as a policy maker and law enforcement agency and a financial aid provider
Stem: local authorities that include provincial level government agencies. These  help channeling basic benefits from the government to the local level by providing expertise, advise and monitoring  for proper management of wetlands
Branches : Communities of residents, school children, youth, welfare and other  organizations that could get  together  to conserve, restore, abate degradation and  monitor wellbeing of wetlands

Since August 2009, an innovative system has been helping to treat wastewater from the water treatment plant at Saint-Just (5000 population equivalent) in the Hérault department (France). Called the ‘Zone Libellule’ (‘libellule’ is the French word for dragonfly, and an acronym for ‘LIberté Biologique Et de LUtte contre les poLluants Emergents’—Biological freedom and fight against emerging pollutants), it is made up of a series of wetlands containing over 7000 plants from 48 different species.
