Waste Water Testing for Pollution Board Compliance
If your unit discharges trade effluent or sewage, your consent order sets limits, and lab reports are how you show you meet them. The testing is done by a laboratory recognised under the Environment (Protection) Act, 1986 and accredited by NABL. We coordinate the sampling, check results against your consent conditions and file the reports with HSPCB or your state board.
What it is
Waste water testing means taking a sample of the effluent or sewage your premises releases and having a laboratory measure what is in it. Typical parameters are pH, suspended solids, BOD, COD and oil and grease. Your process may add others, such as heavy metals.
The duty comes from your consent under Section 25 of the Water (Prevention and Control of Pollution) Act, 1974. That section lets the State Board attach conditions on the nature, composition, temperature, volume and rate of your discharge. The default limits are the general standards in Schedule VI of the Environment (Protection) Rules, 1986, unless your industry has its own notified standard or the board has set a tighter one.
Testing is done by environmental laboratories recognised under Section 12 of the Environment (Protection) Act, 1986. Recognition is granted by the Central Pollution Control Board and requires NABL accreditation to ISO/IEC 17025:2017. We are not a laboratory. We arrange the test with such a lab, track your consent conditions and handle the reporting.
Who it applies to
Units holding a consent to operate
Any factory, workshop or facility whose consent under the Water Act carries effluent or sewage monitoring conditions.
Units with an ETP or STP
If you run an effluent or sewage treatment plant, the treated outlet is tested against your limits.
Green MSMEs on self-declaration in Haryana
For applications from 15 November 2025, HSPCB grants a first consent to operate to green-category MSMEs on self-declaration, with NABL-accredited lab reports to be submitted within 90 days.
Units applying for or renewing consent
A fresh analysis report is normally part of the file for HSPCB consent to establish and operate, whether fresh or a renewal.
Units facing a board notice
Say a Faridabad electroplating unit gets a notice after a board sample fails on oil and grease. It needs an independent test and a record of what it fixed.
Why it matters
It proves you are within limits
Your consent comes with conditions. A dated report from a recognised lab is your evidence that you meet them.
It catches problems early
A rising COD reading is an early warning. In practice, it often means the ETP needs attention, and you would rather find that out before the board inspector does.
It keeps renewals and audits clean
Consent renewals, the annual Environmental Statement, ISO certification audits and buyer audits all ask for test data.
Schedule VI standards at a glance
These are the general standards for discharge of effluents in Schedule VI, Part A of the Environment (Protection) Rules, 1986, for the most commonly tested parameters. Your consent order may set different or additional limits. Where it does, the consent order is what you must meet.
| Parameter | Inland surface water | Public sewers | Land for irrigation |
|---|---|---|---|
| pH | 5.5 to 9.0 | 5.5 to 9.0 | 5.5 to 9.0 |
| Suspended solids (mg/l, max) | 100 | 600 | 200 |
| BOD, 3 days at 27°C (mg/l, max) | 30 | 350 | 100 |
| COD (mg/l, max) | 250 | — | — |
| Oil and grease (mg/l, max) | 10 | 20 | 10 |
| Temperature | Not more than 5°C above the receiving water | — | — |
Here is the catch: many industries, such as dairies, sugar mills, textiles and electroplating, have their own standards in other schedules of the same Rules. A dairy near Palwal sending treated water to a drain may face a different list from a garment unit sending it to a CETP. So we read your consent order first and test against what it says.

How it works
Read your consent conditions
We list every parameter, limit, outlet and testing frequency in your consent order, and note any industry-specific standard that applies.
Book a recognised laboratory
We engage an environmental lab recognised under the Environment (Protection) Act and NABL-accredited for the parameters you need, and fix a sampling date.
Coordinate sampling at your premises
The lab samples the ETP inlet and outlet or the final discharge point. We make sure every outlet in your consent is covered.
Check results against your limits
We compare each value with your limits and flag anything close to the line, so you can act before filing.
File the report with the board
We upload the report on HSPCB’s online consent portal or your state board’s system, and keep a dated record for renewal and the Environmental Statement.
Timelines
Test as often as your consent says
Your consent order sets the frequency. Some units test monthly, others quarterly or half-yearly.
Allow for lab turnaround
BOD alone needs three days of incubation at 27°C, so the report never comes back the same day. We plan sampling around your filing dates.
Green MSMEs in Haryana
NABL-accredited lab reports within 90 days of a self-declaration consent, for applications from 15 November 2025.
File Form V by 30 September
Form V for the financial year ending 31 March is due to the State Board by 30 September.
What happens if the results fail
Board directions and closure
Under Section 33A of the Water Act, the board can direct closure of a unit or stop its electricity and water supply.
Penalties under the EP Act
Section 15 of the Environment (Protection) Act, 1986 now provides a penalty of ₹10,000 to ₹15 lakh, with up to ₹10,000 a day for a continuing breach.
Board sampling under Section 21
A board officer can sample your effluent under Section 21 of the Water Act. The sample is split into two sealed parts, and you can ask for the second part to be tested elsewhere.
Frequently asked questions
Can Taxhint test my waste water?
No, we do not run a laboratory. Testing is done by environmental laboratories recognised under Section 12 of the Environment (Protection) Act, 1986, which must hold NABL accreditation to ISO/IEC 17025:2017. Our role is to read your consent order, engage a suitable lab, coordinate sampling at your site, check the results against your limits and file the reports with your State Board.
Which limits does my effluent have to meet?
You must meet the limits in your consent order. Where the order does not set its own, the general standards in Schedule VI of the Environment (Protection) Rules, 1986 apply. For discharge to inland surface water these include BOD of 30 mg/l, COD of 250 mg/l, suspended solids of 100 mg/l and pH between 5.5 and 9.0. Some industries have their own notified standards, and we check those first.
How often do I need to test?
As often as your consent order says. There is no single national frequency for every unit, so the conditions page of your consent to operate is the rule that binds you. Some orders ask for monthly analysis, others for quarterly or half-yearly reports. We build a testing calendar from it.
Does the lab have to be NABL-accredited?
For reports filed with the board, yes in practice. CPCB grants recognition under the Environment (Protection) Act only to labs holding NABL accreditation to ISO/IEC 17025:2017. HSPCB’s self-declaration route for green MSMEs, for applications from 15 November 2025, also asks for NABL-accredited lab reports within 90 days. We only work with labs that meet both tests for your parameters.
What is the difference between public sewer and inland surface water limits?
Discharge into a public sewer or a common effluent treatment plant has looser limits because it is treated again downstream. Under Schedule VI, BOD for public sewers is 350 mg/l, against 30 mg/l for inland surface water. Suspended solids are 600 mg/l against 100 mg/l. Your consent order states which category your outlet falls in, and we test against that.
What if the board takes its own sample and it fails?
Ask for the second sealed part to be tested independently. Under Section 21 of the Water Act, a board sample is divided into two parts, sealed and signed by the officer and the occupier, and the occupier can have the second part sent to another laboratory. We help you get that test done quickly and prepare a reply with your corrective steps.
Do I need waste water testing for consent renewal?
Yes. Renewal and fresh consent files include a recent analysis of your effluent or treated sewage. Under the HSPCB order for applications from 15 November 2025, units are asked to apply for consent to operate 90 days before their consent to establish expires. We arrange a test early enough that the report is ready when the file goes in.
Where does the test data go after filing?
It goes into your Environmental Statement as well as your board record. Rule 14 of the Environment (Protection) Rules, 1986 requires units holding consent under the Water or Air Act to file Form V by 30 September for the year ending 31 March. Keeping the year’s lab reports in one place makes that filing straightforward.
What does the testing cost?
The laboratory charges its own fee for sampling and analysis, which depends on the number of parameters and outlets. There is no separate government fee just for testing. Our coordination and filing fee is quoted before you commit. Share your consent order and we will give you an exact figure for the whole cycle.
What it costs
Our fee plus the government fee that applies to your case, quoted before you commit. Tell us the situation and we will price it exactly.
There is no government fee for the test itself. The laboratory bills sampling and analysis separately. HSPCB consent fees apply only when you apply for or renew consent.
