The meat producing sector are among primary users of global freshwater resources within the sector of agriculture and livestock. Processing of meat facilities known as MPP’s generate substantial volumes of wastewater during both the slaughtering process and facility cleaning. This wastewater, referred to as slaughterhouse wastewater (SWW), requires substantial treatment to ensure safe and environmentally friendly discharge because it contains high levels of organic materials and proteins. As a result, SWW treatment and disposal are crucial for maintaining public health. In that chapter, we study about the regulatory system pertinent management of slaughterhouse wastewater (SWW), its environmental ramifications, health implications, and the distinctive attributes of slaughterhouse waste. Due to the varying pollutant levels resulting from the type and quantity of killed flora and fauna, which can change within the meat industry, SWWs are typically assessed through bulk parameters. The characteristics of SWW, such as Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), and Total Suspended Solids (TSS), are key pollutant affecting sewage system. When SWW combines with the sewage system, it adds to the burden on both the sewage network and sewage treatment plants (STP). Therefore, employing on-site treatment utilizing integrated processes emerges as the optimal approach for treating and disinfecting slaughterhouse effluents, ensuring their safe discharge into receiving waters.
