and unusual sights happened recently‚ such as Yangtze River turns blood red in Chongqing. Water pollution in China are usually triggered as accidents. Uncontrollable wastewater discharges are usually caused by the inadequate wastewater storage and sewage treatment facilities. Industrial wastewater outflows‚ and such accidents lead to reduction of fresh drinking water supply as the fresh water is used to dilute the pollutant released immediately. The causes of degradation of fresh drinking water level

defines waste as “useless or worthless material; stuff to be thrown away” (Zero Waste America Is a…). It is also categorized into different types such as municipal waste‚ industrial waste‚ hazardous waste‚ construction and demotion waste‚ sewage and so on. Sewage is classified as one of the most serious type of waste because it always happen everyday. Wastewater is defined as “a combina- tion of one or more of: domestic effluent consisting of black- water (excreta‚ urine and faecal sludge) and greywater

More than 95% of urban sewage is released into the near water way or field due to inadequate or lack of treatment plants in developing countries. More sewage water treatment plants should be installed in cities and industrial belts’

Biochemical Oxygen Demand: Organic wastes that decay in a body of water. decrease the amount of oxygen found in it. The living things in the lake need oxygen to survive. If the oxygen level is depressed to zero‚ all fish in the lake die. Any decomposition that does not contain oxygen starts to generate noxious gases such as Hydrogen Sulfide.

based on available data show that half the organic waste is from the domestic sector (PEM‚ 2003). As stated in the EMB report‚ domestic wastewater discharges contribute highest to the BOD load as the lack of sewage treatment system allows more than 90 percent of inadequately treated domestic sewage to be discharged into surface waters‚ which contain bacteria and viruses that threaten human life. Geographically‚ data show that one-third (30 percent) of BOD generation comes from Metro Manila and Region
