Analyst performing water quality testing in the Envi Tech AL accredited laboratory

Accredited Water & Wastewater Analysis

Water Testing Laboratory for Drinking, Process and Wastewater Compliance

Envi Tech AL operates an ISO/IEC 17025:2017 accredited water testing laboratory serving industries, hospitals, hotels, exporters, housing societies and maritime operators across Pakistan. From a single drinking water sample to a full effluent compliance programme, every analysis is performed under documented laboratory discipline and delivered as a verifiable report your regulator, buyer or auditor can trust.

One laboratory, every water compliance requirement

Water quality decisions carry regulatory, commercial and public-health consequences. Our water testing lab supports the people accountable for those decisions: facility and utility managers proving drinking water safety, compliance officers meeting Sindh EPA and Punjab EPA monitoring conditions, QA teams protecting product quality, exporters answering buyer audits, and building operators safeguarding residents and guests. Whatever the requirement, the deliverable is the same - accurate results, clear reporting and a defensible paper trail.

Drinking water testing to WHO and PEQS requirements

We analyse drinking water, bottled and filtered water, and municipal or borehole supplies against the World Health Organisation guideline values and Pakistan's Environmental Quality Standards for drinking water. Routine physico-chemical analysis covers pH, total dissolved solids, turbidity, hardness, chloride, sulphate, nitrate and fluoride; trace metal analysis by atomic absorption spectrometry covers arsenic, lead, iron, chromium and other health-significant metals; and microbiological examination screens for total coliforms and E. coli - the decisive indicators of faecal contamination. Reports state each result against its applicable limit, so safe is never a matter of interpretation.

Wastewater and effluent testing against SEQS limits

Industrial units discharging to sewer, sea or inland water are bound by the Sindh Environmental Quality Standards and corresponding Punjab requirements. Our laboratory quantifies the full effluent panel - pH, BOD5, COD, total suspended solids, oil and grease, sulphides, phenolic compounds, temperature and the regulated heavy metals including chromium, copper, zinc, lead, cadmium and nickel - and reports compliance status parameter by parameter. For facilities operating effluent treatment plants, we test inlet and outlet streams to demonstrate ETP performance for EMR submissions and buyer audits.

Process, RO and utility water analysis

Production lines, boilers, cooling towers and reverse osmosis plants each impose their own water quality demands. We test process and product water for food, beverage, pharmaceutical and textile manufacturers; monitor boiler feed and cooling water for hardness, conductivity, silica and scaling indices; and assess RO plant performance through feed, permeate and reject analysis - identifying membrane deterioration before it becomes product risk or energy waste.

From sample to verified report

A controlled path from requirement to usable laboratory evidence

Good scoping protects cost, turnaround planning, sample validity and report usefulness.

  1. 01Define the requirement

    Tell us the purpose: EPA submission, buyer audit, internal QA or troubleshooting. We match parameters, methods and report format to it.

  2. 02Sampling

    Our field teams collect samples across Karachi and Lahore using correct containers, preservation and chain-of-custody documentation. For other cities, contact the laboratory before dispatch so sample acceptance and transit conditions can be confirmed.

  3. 03Accredited analysis

    Testing is performed under our ISO/IEC 17025:2017 quality system with documented methods, calibrated instruments and internal quality control.

  4. 04Verifiable reporting

    Results are issued as a formal report stating each result against its applicable limit - and every report can be authenticated through our online report verification portal.

Frequently asked questions

Answers before you request a quotation

How much does water testing cost in Pakistan?

Cost depends on the parameters required: a basic drinking water panel costs considerably less than a full SEQS effluent panel with heavy metals. Send your requirement through the quotation form or WhatsApp and the laboratory will return a precise quotation in PKR.

How long does laboratory water analysis take?

Routine analysis time depends on the parameter list, sample condition and method requirements. Microbiological tests require incubation periods set by the method. If a deadline is critical - a vessel sailing, an audit date, an EPA submission - tell us when you book and the laboratory will plan around it.

Which standards do you test water against?

Drinking water is assessed against WHO guideline values and the Pakistan Environmental Quality Standards; effluent and wastewater against SEQS 2016, NEQS and Punjab requirements as applicable; and process water against your industry or buyer specification. Every report states the limit alongside the result.

I am not in Karachi or Lahore - can you still test my water?

Field sampling teams operate across Karachi and Lahore. For other cities, contact the laboratory before dispatch so the team can guide bottle selection, preservation, labelling and transit conditions before accepting the sample.

How do I know the report is genuine?

Every Envi Tech AL report can be authenticated through the online report verification portal using the report number and date - a safeguard regulators, buyers and auditors increasingly expect.

Need water testing with a deadline attached?

Send the requirement today - parameters, purpose and timeline - and the laboratory team will confirm scope, quotation and sampling schedule.
