This study was carried out during the period from January 2005 to November 2005 at Mymensingh Periurban area to evaluate the use of wastewater for crop production. Dimensions of three channels carrying wastewater were measured at different distances and the mean discharges through the channels were estimated. Wastewater characteristics such as pH, EC, TDS, NH4 and PO4 were determined. The plants growing in the channel sides were also recorded and analyzed for NH4 and PO4 contents. Participatory rural appraisal was conducted to know advantages and disadvantages of using wastewater. Our results show that farmers were interested to use wastewater for irrigation provided it had been pretreated by biological or other means. Natural purification of wastewater by water hyacinth is possible. After appropriate treatments it may be used as irrigation water or released in rivers or ponds. High paddy yields may be achieved if the pH value is high.
