VEPL – Modular STP for Commercial Buildings
(Eco-Friendly, Scalable & Natural Wastewater Recycling System with Reed Bed/Plantation STP Option)
Ventilair Engineers Pvt. Ltd. (VEPL) presents a Modular Sewage Treatment Plant specifically designed for commercial buildings, including offices, shopping complexes, business parks, hotels, and multiplexes. This system is available in flexible module-based units, allowing for easy installation, scalability, and minimal footprint.
What makes this VEPL STP unique is the option to integrate a reed bed or plantation-based root zone system — enabling eco-friendly secondary or tertiary treatment, low power consumption, and 90% water reuse with zero discharge. Ideal for green-certified buildings, these modular STPs are built to CPCB/SPCB compliance and deliver reliable performance with low O&M cost.
