For a commercial installation, the AMC is arguably more important than the equipment choice, because it determines what happens on the day the plant stops — and for a hospital, a factory canteen or a 200-flat society, that day has a cost measured in far more than the repair.
Commercial AMC comes in two forms. Comprehensive includes parts — membranes, cartridges, pumps, lamps — and typically runs 10-14% of capital cost annually. Non-comprehensive covers scheduled visits and labour only, at 5-8%, with parts billed as consumed. Comprehensive is more expensive on paper and usually better value in practice, because it aligns the vendor's incentive with plant uptime rather than with billable replacements.
The negotiation that matters is not the percentage. It is the response time, the escalation path, whether critical spares are held locally, and whether the inclusion list is specific enough to prevent arguments later.
Capacity, application & indicative cost
| AMC type | Typical annual cost | Includes | Best for |
|---|---|---|---|
| Non-comprehensive | 5-8% of capex | Scheduled visits, labour, minor consumables | Sites with in-house maintenance capability |
| Comprehensive | 10-14% of capex | All the above plus membranes, cartridges, pumps, lamps | Most commercial sites |
| Comprehensive + priority SLA | 12-18% of capex | Above plus guaranteed response, local spares | Hospitals, production-critical, large societies |
Figures are indicative planning ranges for budgetary approval, not quotations. Actual cost and achievable output depend on your feed-water analysis, materials of construction, automation level, instrumentation, storage and site conditions.
What must be written into the contract
- Response time for breakdowns, stated in hours, with a named escalation contact — not 'at the earliest'.
- Number and frequency of preventive visits, with a defined checklist for each.
- Itemised inclusion list: which parts are covered, and explicitly which are not.
- Consumable replacement intervals, and whether replacement is on schedule or on condition.
- Whether critical spares (membranes, pump, HP switch) are held locally or shipped on failure.
- Water quality guarantee: output parameters and how they are verified at each visit.
- A service log, physical or digital, signed at every visit — this is your evidence base.
Tip
Preventive maintenance that actually prevents failures
- Daily: log feed and product TDS, and operating pressures. A trend tells you about fouling weeks before a failure does.
- Weekly: backwash multigrade and carbon filters; check salt level if a softener is installed.
- Monthly: verify antiscalant dosing rate, inspect for leaks, clean UV quartz sleeve.
- Quarterly: replace cartridge filters; verify auto-flush operation; check pump current draw.
- Annually or on condition: membrane CIP or replacement based on differential pressure and salt rejection trends, UV lamp replacement on hours.
Total cost of ownership, not just capex
Capital cost is usually 30-40% of what a commercial water system costs you over five years. The rest is power, membrane and cartridge replacement, reject water, and labour. Two plants with identical price tags can differ by 60% in five-year TCO.
- Power — energy-efficient pumps and correctly sized motors are the largest controllable operating cost on plants above 500 LPH.
- Recovery ratio — a plant recovering 70% instead of 45% cuts both your feed water bill and your reject disposal volume substantially.
- Membrane life — driven almost entirely by pre-treatment quality and flushing discipline, not by membrane brand.
- Consumables — cartridge filters, antiscalant and salt for softener regeneration, budgeted monthly rather than as surprises.
- AMC and downtime — for a production facility, unplanned downtime usually dwarfs every other line item.
Why specify with us
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.
Treatment architecture
- 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.
