Mobile Sewage Treatment Unit
Portable | Rapid Deployment | Complete On-Wheels Sewage Treatment
VEPL’s Mobile Sewage Treatment Unit (MSTU) is a fully integrated, on-wheel wastewater treatment plant designed for temporary, emergency, or remote applications. Mounted on a trailer or vehicle chassis, the MSTU offers on-site sewage treatment without the need for civil foundations or long installation timelines.
Built with modular biological and filtration technologies like MBBR or SBR, this solution delivers high-quality treated water suitable for discharge or reuse — even in remote or shifting project environments.
