What makes water testing different in Kolkata
Local supply in Kolkata runs roughly 200-550 ppm TDS from municipal mixed sources, and the water is moderate. Those two facts change the schedule and the cost of water testing here more than anything else does.
Kolkata's comparatively moderate TDS means consumables reach close to their rated life, so two service visits a year is generally sufficient and membranes commonly last 18-24 months. Do not stretch the pre-filters on that basis though — they are cheap and they are what keeps the membrane alive.
Water in Kolkata is comparatively moderate, so whole-house scaling is less of an issue here than in India's hard-water belt, and a separate softener is usually unnecessary.
Hooghly-fed treated supply is moderate in TDS, but Kolkata and the wider Bengal delta sit in a documented arsenic and iron belt — and arsenic is exactly what a UV purifier cannot touch. If you draw from groundwater anywhere in the district, RO is a health requirement, not a preference, and iron pre-filtration protects the membrane.
TDS and AQI figures for Kolkata are indicative planning ranges compiled from publicly reported CPCB and CGWB-style patterns. They are not live readings and they vary by locality, borewell depth and season. Test your own supply before making a purchase decision — water testing in Kolkata costs ₹300-₹2,500.
Water Testing charges in Kolkata
Indicative market rates, useful for sanity-checking any quote you receive. Providers in the same city routinely differ by 40-60% on identical work, which is the whole reason to collect more than one.
| Test panel | Parameters covered | Indicative cost | Turnaround |
|---|---|---|---|
| On-site basic | TDS, pH, hardness, residual chlorine | ₹300 - ₹800 | Immediate |
| Standard drinking water | Above plus iron, nitrate, fluoride, chloride, sulphate | ₹1,500 - ₹2,500 | 3-5 days |
| Bacteriological | Total coliform, E. coli | ₹800 - ₹1,500 | 3-5 days |
| Heavy metals | Arsenic, lead, mercury, cadmium, chromium | ₹2,500 - ₹4,500 | 5-7 days |
| Full IS 10500 panel | All drinking-water parameters | ₹4,000 - ₹8,000 | 7-10 days |
| Borewell commissioning panel | Full chemistry plus bacteriological | ₹3,000 - ₹5,500 | 5-7 days |

What's included in water testing
This is the scope we ask providers to quote against. Holding every quote to the same list is what makes them comparable — otherwise you are choosing the cheapest number rather than the best value.
- Sample collection at your property, following correct protocol so the result is meaningful.
- On-site measurement of TDS, pH, hardness and residual chlorine, given to you immediately.
- Lab analysis of the parameters in your chosen panel, at an accredited laboratory.
- A written report with each parameter set against the IS 10500 permissible limit.
- A plain-English interpretation — what is within limits, what is not, and what it means.
- A specific purification recommendation based on the results, not on a product catalogue.
Not included
- The purifier or treatment equipment subsequently recommended.
- Repeat sampling where a result is disputed, unless a contamination event is suspected.

- 4Book whoever you wantYou deal with the provider directly and pay them for the work. There is no obligation to accept any quote.
Who genuinely needs a lab test
- Anyone on borewell supply. Groundwater chemistry is local, variable and invisible.
- Anyone on tanker supply, where the source changes and so does the content.
- Households in documented arsenic belts — the Ganga-Brahmaputra plain, covering much of West Bengal, Bihar, Assam and eastern Uttar Pradesh.
- Households in fluoride belts, notably parts of Rajasthan, Gujarat, Telangana and Andhra Pradesh.
- Anyone near industrial clusters, tanneries or intensive agriculture, where heavy metals and nitrate are plausible.
- Anyone about to spend more than ₹15,000 on a purifier. The test is 5-10% of the spend and determines whether the spend is correct.
- Any household where someone has had a waterborne illness.
Tip
How to read your report
Every parameter should be printed against its IS 10500 acceptable limit and permissible limit. Acceptable is the desirable level; permissible is the maximum tolerable in the absence of an alternative source. A result between the two is not a crisis but is worth treating; a result above permissible needs action.
The parameters that most often change a purchase decision are TDS (RO or not), total hardness (softener or not), iron (pre-filtration before the membrane), nitrate and fluoride (RO required, UV useless), arsenic (RO required, and this is a health issue rather than a taste one), and coliform count (UV required).
Be sceptical of any free test offered by someone selling purifiers, particularly the TDS-meter demonstration at your door. The classic version uses an electrolysis device that makes any water turn brown and proves nothing about safety. A real test produces a report on laboratory letterhead with parameters, methods and limits.
What a test typically changes
The two most common outcomes are money saved and risk found. On low-TDS municipal supply, the test frequently shows RO is unnecessary and a UV+UF unit at half the price with no water wastage is the correct fit — a saving on purchase, on running cost and on thousands of litres a year.
On groundwater, the test more often finds something. Hardness high enough to justify a separate softener for the bathroom line, iron high enough to need pre-filtration before the membrane, or occasionally nitrate or fluoride above permissible limits — which changes the purchase from a preference into a requirement.
What "verified" means for providers in Kolkata
It is a specific claim, so here is exactly what it covers. Every provider on this network has:
- Government photo ID and address verified at onboarding
- Business registration or GST number on file where applicable
- References checked from at least three completed jobs
- Agreed to publish itemised pricing before starting work
- Agreed to record input and output TDS on every service slip
- Removed from the network after two unresolved customer complaints
Verification covers identity, registration and references. It is not a guarantee of workmanship on any individual job, and we are not a party to the contract between you and the provider — you engage and pay them directly. If a job goes wrong, tell us: providers are removed from the network after two unresolved complaints.
