Frequently Asked Questions
Clear answers regarding our plant design capacities, compliance standards, and maintenance contracts.
Do you offer Annual Maintenance Contracts (AMC) for existing plants?
Yes. We offer comprehensive Operations & Maintenance (O&M) and Annual Maintenance Contracts (AMC). Our team can take over the maintenance and operation of your existing RO, ETP, or STP facilities, even if they were originally installed by another vendor.
What capacities do your RO and wastewater treatment systems handle?
Our solutions are highly scalable. We design and install everything from compact, skid-mounted RO units for commercial buildings to large-scale, multi-stage effluent treatment plants (ETP) for heavy manufacturing and industrial parks.
How do you ensure compliance with Pollution Control Board (PCB) norms?
Environmental compliance is built into our engineering phase. We analyze your raw effluent data and design a treatment process that guarantees the final discharged or recycled water meets or exceeds all local and national statutory parameters.
Can you upgrade or automate our older water treatment facility?
Absolutely. We specialize in retrofitting and capacity enhancement. Whether you need to increase your plant's throughput, upgrade your filtration media, or integrate modern PLC-based automation for better monitoring, we can modernize your existing setup.
