VEPL Compact Sewage Treatment Plant for Villas & Small Housing Units
MBBR-Based | Plug-and-Play | Low-Maintenance | Fully Accessorized
The VEPL Small-Capacity STP is a compact, prefabricated, and plug-and-play sewage treatment solution designed for individual villas, small gated communities, and low-density residential clusters. It uses Moving Bed Biofilm Reactor (MBBR) technology, ideal for domestic sewage with variable load.
The plant provides complete treatment – primary, secondary, tertiary, and ultrafiltration, along with filter press, UV disinfection, ozonator, chlorine & poly dosing, and redundant pumps and blowers (1 working + 1 standby) for operational reliability.
