Sewage is the waste generated from residential, institutional, commercial and industrial establishments. Due to the hazardous impacts of municipal, industrial and hospital wastewater on water, soil, air and agricultural products, wastewater treatment and the proper disposal of the sludge produced are indispensable from an environmental safety point of view. Moreover, reuse of sewage is the most sustainable and long-term solution to the problem of water scarcity. Sewage Treatment Plants (STP) treat the sewage and waste water to produce a cleaner, more environmentally friendly effluent that is safe for disposal, gardening/agricultural use or domestic use in toilets, etc. Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent) that is safer for discharge into the environment.
