The proposed project will take place near the Meghna River in Bangladesh (Figure 1). The Meghna River originates in Bangladesh and is one of the three rivers that form the Ganges Delta. It is one of the most important rivers in Bangladesh. Two tributaries of the Meghna River, the Bisnandi and Jhawchar Canals, have been selected for this pilot project. They are located nearby the proposed future drinking water intake locations.
The Bisnandi Canal is located just upstream of the Bisnandi intake point. There is a considerable threat to water quality at that intake point. The Bisnandi Canal receives discharges from numerous small- and medium-sized textile industries, as well as untreated domestic wastewater from the housing areas located along the canal. The canal is highly polluted.
...
The Jhawchar Canal is located just downstream of the second proposed intake point at Haria. This canal is also affected by domestic wastewater discharges and by the discharge of a paper mill. It is one of the most polluted tributaries of the Meghna. Due to tidal impacts on the Meghna River (tidal excursion), water quality in this canal could impact the drinking water intake point at Haria.
