Engineered water treatment · Since 2007
AQUASTAG Technologies LLP engineers water treatment systems for industry, institutions and homes across India — sized from your actual water analysis, commissioned against measured figures, and maintained long after handover.
What we do best
Hardness and dissolved solids cause the majority of water problems in Indian industry. These are the three systems we build most, and the three we know deepest.
Core capabilityHardness removal · Ion exchange
Ion-exchange softening plants that strip calcium and magnesium out of hard borewell and municipal water, protecting boilers, chillers, laundries and every heated surface downstream.
View specifications
Core capabilityScale control · Zero discharge
Salt-free, zero-discharge scale control that stops limescale forming on heated surfaces while leaving the natural mineral content of the water intact.
View specifications
Core capabilityReverse osmosis · 250 – 10,000+ LPH
Turnkey reverse osmosis plants from 250 LPH to 10,000+ LPH — engineered pre-treatment, correctly staged membrane arrays and controls built for continuous industrial duty.
View specificationsChoosing correctly
These two systems are frequently sold interchangeably. They are not interchangeable, and choosing the wrong one wastes money in different ways.
Requires salt, a brine tank and a drain connection.
No salt, no wastewater, minerals retained in the water.
Complete portfolio
Beyond our three core systems, we cover the full water and wastewater cycle — from a single household purifier to a township sewage treatment plant.
Biological treatment · Water reuse
Compact biological sewage treatment plants that meet pollution control board discharge norms and turn wastewater into a reusable resource for flushing and landscaping.
View specifications
Oxidation · Catalytic filtration
Oxidation and catalytic filtration that takes dissolved iron and manganese out of borewell water — ending the red-brown staining, metallic taste and blocked plumbing they cause.
View specifications
Point of use · RO + UV + UF
Multi-stage RO, UV and UF purifiers for homes and offices — specified against your actual tap water rather than sold from a shelf.
View specifications
Monthly rental · Maintenance included
Fully maintained purifiers on a monthly rental — no capital outlay, no service bills, and the unit stays our responsibility for as long as you keep it.
View specificationsWhy AQUASTAG
Most water treatment equipment on the market is broadly similar. The difference in outcome comes from how carefully it is specified, commissioned and looked after. Move your cursor across this section — it behaves like water.
Every proposal starts with what is actually in your water. Equipment specified from a catalogue rather than a test result is the single most common reason a plant underperforms.
Installation is where most suppliers finish. Health checks, retrofits, AMC and breakdown response are core services, not an afterthought bolted on to a sale.
Every system is delivered against AWEP, our internal protocol. Commissioning figures are measured, recorded and signed — so performance is documented, not asserted.
As an IEC-registered exporter we supply and support installations beyond India, with documentation and packing to suit international freight.
The AWEP Protocol
AWEP governs how an AQUASTAG system is designed, built, commissioned and handed over. It replaces informal judgement with defined checkpoints and measurable outcomes.
Service & support
A water treatment plant is a piece of process equipment, not an appliance. It needs measurement, cleaning and parts on a schedule.
Mechanical installation, electrical termination, hydraulic testing and documented performance handover — the plant is not signed off until it meets its design figures.
A measured diagnostic of an existing plant — water tested, performance compared against design, and a written report with costed recommendations.
Targeted upgrades that restore performance and add capacity to an existing plant — usually at a fraction of what full replacement costs.
Scheduled preventive servicing, priority breakdown response and predictable annual cost — so plant performance stops depending on someone remembering to check it.
Rapid diagnosis and repair when a plant stops — with the root cause identified so the same failure does not return next quarter.
Sectors we serve
A dialysis unit, a dyeing house and a gated community all have hard water. They need entirely different responses to it.
Process water must meet a documented pharmacopoeial standard consistently, and every deviation has to be traceable for audit.
Water is an ingredient. Mineral content changes taste, hardness scales cook kettles and CIP systems, and microbiological control is non-negotiable.
Hard water ruins guest experience — scaled showers, spotted glassware, greying linen — while quietly destroying boilers and laundry equipment.
Dialysis, sterilisation and laboratory work each demand a different water standard, and interruption is not an acceptable outcome.
Scale on heat exchangers, boilers and cooling circuits raises energy consumption long before it causes visible failure.
Borewell supplies swing in hardness and TDS across seasons, and a township has to treat sewage as well as supply water.
Large drinking demand concentrated into short breaks, hostel loads that peak twice a day, and a very low tolerance for water-borne illness.
HVAC cooling circuits scale continuously, cafeteria equipment fails early, and facilities teams rarely have in-house water expertise.
Our range
Forty-five seconds across the full range — RO plants, water softeners, purifiers, demineralisation, effluent and sewage treatment.
Client feedback
Water treatment is bought on trust, because most of what it does is invisible. These are the outcomes our clients describe.
Our borewell was running at 1,150 ppm and the previous plant could not hold output through a full shift. AQUASTAG re-did the pre-treatment before touching the membranes, which nobody else had suggested. Two years on, the permeate is still under 40 ppm and we have not replaced a single element.
We had scale building up in the boiler within weeks of every descaling. They tested the water, showed us the hardness figures and sized the softener against our actual steam load rather than quoting a standard model. Salt consumption came in almost exactly where they said it would.
Every bathroom in the block had yellow-brown staining and the residents were convinced it was the plumbing. AQUASTAG identified dissolved iron in the borewell and installed an iron removal filter ahead of the softener. The staining stopped completely within a fortnight.
The mini STP sits directly below our clubhouse, so odour was the thing we were most worried about. They covered the tanks and enclosed the blowers as part of the design rather than as an extra. We now reuse the treated water on the landscaping and our fresh water bill has dropped noticeably.
What I valued was being told what we did not need. We had asked for a full replacement and they came back recommending a retrofit of the pre-treatment and the high-pressure pump instead. It cost a fraction of a new plant and the output is back to the original specification.
We run eighty rooms and the laundry was consuming detergent far beyond norms. The central softener paid for itself inside the first year on chemical savings alone, and the guest complaints about scale marks on the shower fittings have stopped entirely.
Case studies
Staining nobody could trace, output that had quietly halved, a plant that smelled. Four worked examples with the diagnosis and the measured outcome.

Common questions
If your question is not answered here, ask us directly — we will give you a straight answer.
We design, manufacture, install and maintain water treatment systems. Our core business is water softeners, chemical-free water conditioners and industrial and commercial reverse osmosis plants, alongside sewage treatment plants, domestic purifiers and rental systems. We have been operating since 2007 and are based in Hyderabad, Telangana.
Hyderabad and Telangana are our primary service region, with installation and maintenance teams across India for larger projects. As an IEC-registered exporter we also supply equipment internationally, and our enquiry form accepts phone numbers from any country.
A softener removes hardness by ion exchange and is required wherever a specification demands measurably low hardness — boiler feed, RO pre-treatment, commercial laundry or dyeing. A conditioner leaves the minerals in the water but stops them adhering as scale, with no salt, no waste stream and minimal maintenance. We recommend based on your water analysis and duty, not on which system carries a higher invoice.
Within 24 working hours. You receive an automatic acknowledgement the moment you submit the form, and an engineer who understands your requirement follows up personally. Our office hours are Monday to Saturday, 10:00 AM to 6:00 PM IST.
Yes. We do not quote water treatment equipment without knowing what is in the water. For sites in and around Hyderabad we arrange a visit and sample; for locations further afield we work from a laboratory analysis report and site details you provide.
Yes. Our health check, repair, retrofit and AMC services cover RO plants, softeners, conditioners, purifiers and STPs regardless of who originally supplied them.
Send us your requirement and an engineer responds within 24 working hours — with a recommendation, not a sales pitch.
