What is an Iron Removal Plant and do I need one?
An Iron Removal Plant (IRP) is a water treatment system that removes excess iron and manganese from your water supply. You likely need one if your water leaves rust-coloured stains on clothes, utensils, or bathroom surfaces, has a metallic smell or taste, or if your borewell water tests show iron levels above 0.3 mg/L (the BIS permissible limit). We can test your water and recommend the right system capacity for your requirement.
How long does it take to install a water treatment plant?
Installation time depends on the type and size of the system. A standard iron removal plant or RO system typically takes 1–3 days. Larger systems like ETP/STP plants or ISI mineral water plants may take 2–6 weeks depending on civil work and system complexity. We give you a clear installation timeline in our quote before work begins.
Do you provide after-sales service and AMC?
Yes — after-sales support is a core part of what we do. We offer Annual Maintenance Contracts (AMC) that include scheduled service visits, filter media checks, membrane inspections, and priority response for emergency issues. We also handle one-time media replacement, cartridge change, and UV lamp replacement for clients who don't have an AMC. We service plants installed by any vendor, not just B-KING.
What is the cost of a water treatment plant?
The cost varies based on the type of system, capacity, and your site requirements. A basic iron removal plant starts from ₹35,000–₹80,000 for residential use, while commercial and industrial systems are priced based on daily volume and design complexity. We provide a detailed, transparent quote with no hidden charges after a free site survey and water test. Contact us for an accurate estimate for your specific requirement.
Do you help with BIS/ISI certification for mineral water plants?
Yes. Our ISI Mineral Water Plant setup is designed from the ground up to comply with BIS IS 14543 standards. We assist with documentation, help you understand the audit requirements, and ensure your plant meets all FSSAI and BIS norms before the inspection. Our clients have successfully obtained their BIS licenses after installation by B-KING.
Do you serve areas outside Kolkata?
Yes — we serve clients across all of West Bengal. Our team regularly travels to Howrah, Durgapur, Asansol, Bardhaman, Siliguri, Jalpaiguri, Malda, Midnapore, Kharagpur, Digha, Bongaon, and surrounding areas for installation and servicing. If you're unsure whether we cover your location, just call us at +91 90834 02525.
How often does a water treatment plant need servicing?
It depends on the system type and daily usage. As a general guide: pre-filters and cartridges need replacement every 3–6 months; RO membranes every 12–18 months; filter media (sand, greensand) every 2–3 years. We recommend a quarterly inspection for commercial systems and a bi-annual check for residential ones. Our AMC covers all scheduled service visits so you never have to worry about tracking this yourself.
Can you service a plant that was not installed by B-KING?
Absolutely yes. We service water treatment plants of all types and brands, regardless of who installed them. Whether it's an iron removal plant, RO system, softener, DM plant, or ETP — our technicians are trained to inspect, diagnose, and service any system. We bring our own tools and can source replacement media, membranes, and parts for most standard configurations.
