In developing countries, the developments of treatment options for sanitation adapted to the local conditions have long been neglected. Constructed wetlands are recognized as cost-effective, technically feasible solution for wastewater treatment. The plants commonly grown on these systems are not worldwide available. Their economic and energetic reuse potentials are very limited. With similar characteristics, Echinochloa pyramidalis revealed a significant pollution removal capacity, with an attractive market potential because of its quality as forage. Their use on treatment systems provides an opportunity to linking sanitation stewardship to food production. In this study, a series of investigations was conducted to evaluate the effects of sanitation treatment processes under free drainage and flooding conditions on the nutritional potential of E. pyramidalis by analysis of their chemical components. The results showed that the nutritive value improved in quality, and E. pyramidalis is recommended as a suitable plant for forage production in treatment wetlands.
