Custom-engineered to your TDS

We supply, install and service commercial and industrial RO plants across Kolkata and West Bengal — from 25 LPH office systems through to multi-thousand LPH industrial plants.

Kolkata has substantial commercial and industrial demand, and feed-water quality here — typically 200-550 ppm TDS from municipal supply blended with borewell water — directly determines the pre-treatment train your plant needs.

Local water is moderately hard, which keeps pre-treatment requirements comparatively modest and improves membrane life. Every quotation is engineered against your own water analysis report.

Designing for Kolkata feed water

Feed TDS band: 200 - 550 ppm
Hardness: moderate
Dominant source: Municipal + borewell blend
Pre-treatment implication: Standard sand + carbon usually sufficient
Expected recovery: 50-65%
Membrane class: Standard brackish-water RO

TDS and AQI figures on this page are indicative planning ranges compiled from publicly reported patterns for this city — not live readings. Actual values vary by locality, borewell depth and season. Test your own supply with a TDS meter (around ₹300), and get a laboratory analysis if you suspect arsenic, fluoride, nitrate or iron.

Industrial areas we serve in Kolkata

We supply and service commercial and industrial water treatment systems across Kolkata's manufacturing and commercial clusters, including:

Salt Lake Sector V
Howrah industrial belt
Dankuni
Taratala

If your facility sits in one of these clusters, mention it in your enquiry — plant rooms in established industrial estates often have specific space, drainage and electrical constraints that we can design around from the outset rather than discover at installation.

Commercial RO plants in Kolkata — FAQs

What is the price of a commercial RO plant in Kolkata?

Indicatively: 100 LPH ₹75,000-₹1,50,000; 250 LPH ₹1,50,000-₹3,00,000; 500 LPH ₹3-6 lakh; 1,000 LPH ₹6-12 lakh. In Kolkata specifically, feed water at 200-550 ppm and moderate hardness means pre-treatment requirements are comparatively modest, which keeps you nearer the lower end of each band. A firm quotation requires a water analysis report.

Do you install and service commercial RO plants in Kolkata?

Yes — supply, installation, commissioning and AMC across Kolkata and West Bengal. Standard 100-500 LPH commercial systems are typically installed within 48-72 hours of site readiness; custom industrial plants take 7-14 days. Response times and local spares holding are stated in writing in the AMC rather than left to assumption — tell us your site location and we will confirm applicable coverage before you order.

What pre-treatment does Kolkata's water need for a commercial RO plant?

With local feed water at 200-550 ppm TDS and moderate hardness, the typical requirement is a multigrade sand filter, an activated carbon filter, with antiscalant dosing specified based on your actual hardness figure. Final design always follows a water analysis.

Which capacity RO plant do I need for my Kolkata facility?

Allow 3-4 litres per person per day for drinking water. Up to 15 people a domestic RO suffices; 15-40 people needs 25-50 LPH; 40-120 needs 100 LPH; 120-300 needs 250 LPH; 300-800 needs 500 LPH. Size on peak draw plus storage rather than daily average — storage is almost always cheaper than extra plant capacity. Our TCO calculator sizes it for you.

What does AMC cost for a commercial RO plant in Kolkata?

Comprehensive AMC including membranes, cartridges and pump cover typically runs 10-14% of capital cost annually; non-comprehensive covering visits and labour only runs 5-8%. Always get the inclusion list itemised and a written response time.
