This project is to control and investigate illegal discharges to the Kaoping River. The result of the investigation has shown 35 illegal pipelines discharging to Kaoping River, which will be publicized and closed if not claimed by the owners. It is estimated that BOD and SS are produced at a rate of 99,367 kg/day and 119,239 kg/day, respectively, from the livestock farms. The actual discharging rate is 40,353 kg/day and 45,323 kg/day for BOD and SS, respectively. The reduction rate is approximately 59.4% (59,014 kg/day) and 62.0% (73,916 kg/day) for BOD and SS, respectively. Severely polluted rivers: River water quality is being monitored at five rivers, including Wan-Nien River and Sa-Ser River. The degree of pollution in these rivers ranges from moderate to severe. Feasibility of pollution reduction plan: Wastewater from livestock farms is to be reduced at its source or recycled. Raising-Bed Pig farms are to be promoted. In addition, manual or automatical collection of the manures will effectively reduce wastewater productions and the loads to the wastewater treatment units. Composting of the manures and the re-collection of the discharging wastewater are the best approach to reduce solid waste/wastewater quantity.
