Constructed wetland is called green technology an alternative sewage sludge treatment all over the world. Overall, CW provides environmentally friendly solution, are low cost. The main objective of the study was the evaluation of Constructed Wetlands for sludge dewatering and recirculation of the effluent produced into the CW after treatment. Sewage sludge was treated using ryegrass plant through winter season by irrigation using fresh water and waste water treated. By measuring important parameters such as heavy metals, physical and biological characteristics, the results showed that it is better to use ryegrass plant by irrigation using treated waste water if compared with the fresh water. It is a good plant with wet sludge soil if compared with dry sludge soil.
