Environmental pollution (air, land, water, etc) because of improper waste management is an alarming challenge for developing countries. Many reports indicate that Coffee production is only environmentally friendly when water is used efficiently and polluted water released from the process is treated accordingly. Disposal of coffee effluent is an important environmental consideration for coffee processing as wastewater is a form of industrial water pollution. Coffee wastewaters are high in organic loadings and exhibit a high acidity. Several reported researches revealed significant river water quality deterioration as a result of disposing untreated coffee waste into running water courses. In this study, the researchers found significant reductions in water quality downstream from coffee processing plants during the wet season. According to different researches, characteristic wastewater from coffee processing have pH 7.71 to 2.51, high concentration of COD (upstream 18.5mg/l and downstream 3244mg/L), BOD (upstream 1.9mg/l and downstream 2967mg/L), total dissolved solid (upstream 73mg/L and downstream 9037mg/l),electrical conductivity (upstream 45mg/l and downstream 1240mg/L) reported that, BOD from (472–551mg/L), COD (9270–14,800 mg/L) and pH 4.40 – 4.27 which indicate that high potential pollution of the coffee effluent when discharged to nearby water bodies and it needs serious treatment before discharging to the environment.
