The full form of WTP in English is Water Treatment Plant.
Water Treatment Plants are facilities designed to purify raw water sources (such as rivers, lakes, and groundwater) to produce safe and potable drinking water for human consumption and other uses. These plants employ various physical, chemical, and biological processes to remove contaminants and ensure the water meets stringent quality standards set by regulatory agencies. As shown in the reference text, WTP is often listed alongside other related types of plants, such as STP (Sewage Treatment Plants), ETP (Effluent Treatment Plants), and WWTP (Wastewater Treatment Plants), highlighting its role in the overall water management infrastructure.
