VEPL is a manufacturer compnay of Sewage Treatment Plants in India. VEPL’s Medium Capacity Sewage Treatment Plant is a compact and highly efficient system designed to treat 50 KLD to 100 KLD of domestic sewage per day. Ideal for housing societies, hospitals, educational campuses, hotels, resorts, and small industrial units, this STP is built using proven biological treatment technologies (MBBR or SBR) and integrates advanced tertiary treatment systems such as Ultra Filtration (UF), UV disinfection, and optional Ozonation to ensure crystal-clear and reusable water.
This system is customizable, modular, and designed to meet CPCB and local pollution control board norms.
