Hi David,
Constructed wetland would be a suitable option to reduce the pollution before further treatment of river water for domestic use. There are different types of constructed wetland design. These depend on flow condition and WQ parameters like COD, TS, heavy metals, nutrients etc. Extensive WQ data will be required to plan and design treatments. Monitoring and controling toxic substances & heavy metals are very important as they negatively impact treatment processes. River bank filtration would be good option to extract better quality water before further treatment.
