We supply, install and service commercial and industrial RO plants across Chennai and Tamil Nadu — from 25 LPH office systems through to multi-thousand LPH industrial plants.

Chennai has substantial commercial and industrial demand, and feed-water quality here — typically 400-1200 ppm TDS from coastal groundwater affected by salinity ingress — directly determines the pre-treatment train your plant needs.

Local water is very hard, so antiscalant dosing or softening ahead of the membrane is usually necessary rather than optional — skipping it is the most common cause of premature membrane failure. Every quotation is engineered against your own water analysis report.

Designing for Chennai feed water

Feed TDS band: 400 - 1200 ppm
Hardness: very hard
Dominant source: Coastal groundwater (saline)
Pre-treatment implication: Softening or antiscalant dosing required
Expected recovery: 35-45% — plan reject handling accordingly
Membrane class: Brackish-water, 3,000 ppm rated

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 Chennai

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

Ambattur Industrial Estate
Sriperumbudur
Oragadam
Guindy
Maraimalai Nagar

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 Chennai — FAQs

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

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 Chennai specifically, feed water at 400-1200 ppm and very hard hardness means you should budget toward the upper end of each band, because antiscalant dosing and a larger pre-treatment train are necessary here. A firm quotation requires a water analysis report.

Do you install and service commercial RO plants in Chennai?

Yes — supply, installation, commissioning and AMC across Chennai and Tamil Nadu. 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 Chennai's water need for a commercial RO plant?

With local feed water at 400-1200 ppm TDS and very hard hardness, affected by coastal salinity, the typical requirement is a multigrade sand filter, an activated carbon filter, and either antiscalant dosing or softening ahead of the membrane — this is not optional at this hardness, and skipping it is the most common cause of premature membrane failure. Final design always follows a water analysis.

Which capacity RO plant do I need for my Chennai 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 Chennai?

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%. On Chennai's high-TDS feed water, budget toward the upper end — membranes and cartridges work harder here and are replaced more often. Always get the inclusion list itemised and a written response time.
