Constructed Wetland (CW )is a natural, low-cost, eco-technological biological wastewater treatment technology designed to mimic processes found in natural wetland ecosystems, which is now standing as the potential alternative or supplementary systems for the treatment of wastewater.
Its an artificial wetlands, a marsh or swamp created, as new or restored habitat for native and migratory wildlife; for anthropogenic discharge such as wastewater, or sewage treatment; for land reclamation after mining, refineries, or other ecological disturbances; and as required mitigation for natural wetlands lost to a development.
The first experiment on the use of wetland plants for treatment of wastewater was carried in the early of 1950 by Dr Kathe Seidel in Germany. The first full scale system were put in operation during the late of 1960s and since then Constructed wetlands systems have been speeding world wide.
Unfortunately, the concept of Biological wastewater Treatment and recycling was not introduced, nor practiced at any stage in Pakistan. In the year 2009-10, Sindhica Reforms Society (SRS) has initiated "Pakistan's first community managed Constructed Wetland" with the support of Dr. Ghullam Akbar Director, Indus For All Programme- WWF Pakistan.
M. Ameen Keryo supervise this pilot project with the technical support of Dr. Roshan Raj Shrestha, the Cheif Technical Advisor- UN Habitat water for Asian cities Programme and developed first successful module in village Majeed Keerio, of District Shaheed Benazirabad in Sindh put in operation in April 2010.
This experiment was quite innovative and difficult to practically execute but the tired less effort, passion, commitment of Sindhica team ultimately completed this intervention in the period of one year and inaugurate in April 2010, Roshan is still providing guidance to Sindhica team time to time as and when required.
