Commercial water treatment, in short

Sizing: allow 3-4 litres per person per day. Up to 15 people a domestic RO suffices; 15-40 needs 25-50 LPH; 40-120 needs 100 LPH; above 120 plan 250 LPH or more with storage.
Indicative capex: 100 LPH ₹75,000-₹1,50,000 · 500 LPH ₹3-6 lakh · 1,000 LPH ₹6-12 lakh · 4,000 LPH ₹22-45 lakh.
Feed-water quality is the biggest cost variable, because it determines the size of the pre-treatment train. No credible quotation exists without a water analysis report.
AMC: comprehensive (parts included) 10-14% of capex annually; non-comprehensive 5-8%. Always get response times in writing.
The most expensive mistake: installing domestic purifiers on a commercial load. They run continuously, exhaust consumables in a fraction of their rated life, and typically fail within 18 months.

Solutions by capacity & use case

Find your scale

Every system below is engineered against your feed water rather than sold from a catalogue. Capex figures are indicative planning ranges for budget approval.

4000 LPH	industrial	Manufacturing and chemical processing, boiler feed, large bottling operations	Fully automatic operation with unmanned running · Stainless steel skid, SS-316 wetted parts · Two-pass configuration available for low-conductivity output	₹22 lakh - ₹45 lakh

Capex ranges are indicative planning figures for budgetary approval, not quotations. Actual cost depends on feed-water quality (which determines pre-treatment), materials of construction, automation level, instrumentation, storage and site conditions.

Why specify with us

Engineered for total cost of ownership, not just purchase price

Capital cost is usually only 30-40% of what a commercial water system costs you over five years. We quote the rest too.

Low total cost of ownership

High-rejection membranes, correctly sized pre-treatment and efficient pumps reduce power draw, consumable spend and reject volume. We quote five-year operating cost alongside capex, because that is the number that actually matters.

Heavy-duty SS-304 / SS-316 build

Corrosion-resistant stainless chassis and wetted parts engineered for continuous 24/7 duty, with SS-316 specified where chlorides or process chemistry demand it.

Rapid on-site servicing & AMC

Pan-India installation and service, with written response times and escalation in the AMC rather than verbal assurances — because plant downtime, not the repair, is your real cost.

Custom TDS tuning

Systems engineered against your actual water analysis — brackish groundwater, municipal supply or heavy borewell input, including high-TDS configurations for 3,000+ ppm feed.

Technical specification

Multi-stage purification architecture

Commercial systems are a treatment train, not a single appliance. Each module protects the one after it — and skipping a stage to save capex is the most common reason plants fail early.

1
Pre-treatment module
Multigrade sand and activated carbon filtration strips suspended solids, turbidity and chlorine that would otherwise oxidise the RO membrane.
2
Softening / antiscalant dosing
Protects membranes from calcium and magnesium scaling. On hard feed water this stage is not optional — it determines membrane life.
3
High-pressure RO module
Heavy-duty booster pumps drive feed water through industrial spiral-wound membranes at 12-18 bar in an array sized for your recovery target.
4
Post-treatment disinfection
UV disinfection and ozonation, with mineral dosing where potable taste and consistency matter.
5
Microprocessor / PLC controls
Auto start-stop on tank level, dry-run protection, high and low pressure cut-offs, and timed membrane flushing — with data logging on industrial plants.

Ask any vendor for the pre-treatment specification, not just the RO capacity. An undersized pre-treatment train is the single most common cause of premature membrane failure and unplanned downtime — and it is where suspiciously cheap quotations save their money.

Custom engineering

Get a system tailored to your water quality

Send us these four things and we can produce a specification-backed proposal rather than a ballpark.

1
Input water source
Borewell, tanker, municipal or surface — and whether it changes seasonally.
2
Daily output needed
Litres per day, and the hours over which you need it produced.
3
Water analysis report
TDS, pH, hardness, chlorides, iron, turbidity. We can arrange a site test if you do not have one.
4
Location & timeline
Site location, available space and power, and when you need it commissioned.

What you get back: itemised equipment specification with makes and models, guaranteed output quality at your stated feed condition, capex plus indicative five-year operating cost, a clear scope boundary, layout and utility requirements, and AMC options with written response times.

Commercial & industrial FAQs

What is the typical lead time for commercial installation?

Standard commercial systems from 100 to 500 LPH are typically installed within 48-72 hours of site readiness, since they are skid-built and largely pre-assembled. Custom industrial plants generally need 7-14 days depending on site readiness, civil work, electrical provisioning and whether non-standard materials such as SS-316 wetted parts are specified.

Do you offer Annual Maintenance Contracts (AMC)?

Yes. All commercial orders can be covered by comprehensive AMC packages including scheduled preventive visits, membrane and cartridge replacement, and priority breakdown response. Comprehensive AMC typically runs 10-14% of capital cost annually; non-comprehensive (visits and labour only) runs 5-8%. Get the inclusions listed line by line before signing.

Can the system integrate with our existing overhead tanks, coolers or chillers?

Yes. Commercial systems use high-pressure sensors (HPS) and level-based auto start-stop, allowing plug-and-play integration with external storage tanks, water coolers and chillers. Tell us your existing tank capacity and height and any chiller model at enquiry stage so pump head and control logic are specified correctly.

What water analysis do you need before quoting?

At minimum: TDS, pH, total hardness, chlorides, iron and turbidity. For industrial applications also silica, sulphates and microbiological load. If you do not have a current report, a site water test can be arranged as part of the pre-quotation survey — specifying a plant without one is guesswork and usually results in a mis-sized pre-treatment train.

Do you handle high-TDS and brackish feed water?

Yes. Brackish water RO configurations handle feed well above standard municipal input, commonly specified up to 3,000+ ppm and higher with two-pass or seawater-class membranes. High-TDS feed changes membrane selection, pump pressure, recovery ratio and reject volume simultaneously, so it must be established at design stage rather than after.

Do you supply and service across India?

Yes — supply, installation and AMC coverage is pan-India, spanning metros, tier-2 and tier-3 industrial centres. Response times and local spares holding differ by location, which is exactly why we state them in writing in the AMC rather than leaving them to assumption. Tell us your site location and we will confirm applicable coverage before you order.

Can we lease or rent instead of buying?

Yes. Rental and OpEx models are common in corporate procurement, bundling installation, all consumables, servicing and breakdown response into a monthly charge. It converts capex to opex and simplifies internal approval, at a higher total cost over five years. Our TCO calculator compares both.
