Industrial Water Testing
Test process water, boiler feed water, cooling tower water and industrial effluent for selected physical, chemical and microbiological parameters. Assess results against the requirements relevant to your application and discharge conditions.
What is industrial water testing?
Industrial water testing checks process, boiler feed, cooling tower and effluent water for microbial load, heavy metals, salinity, COD/BOD and core physical-chemical parameters. Every industry that draws process water or discharges effluent has to answer to CPCB, SPCB and pollution control board requirements, and untested water rarely fails quietly. High salinity scales boilers, uncontrolled COD/BOD in effluent draws regulatory notices, and microbial contamination in cooling towers shortens equipment life long before it shows up on a bill.
Equinox Labs tests process, boiler feed, cooling tower and effluent water at NABL-accredited (ISO/IEC 17025) laboratories, trusted by 95,000+ clients across industries. If your site also needs drinking, construction or borewell water tested, see our full water testing services.
What does contaminated industrial water actually cost you?
Four consequences that hit the plant floor before they hit a compliance report.
- Equipment damage. Unbalanced water scales and corrodes boilers, cooling towers and process machinery.
- Regulatory notices. Uncontrolled COD/BOD in effluent is one of the most common triggers for a pollution board notice.
- Product inconsistency. Process water contamination shows up as batch-to-batch variation in manufactured output.
- Treatment & Maintenance cost. Microbial contamination and biofilm in cooling towers reduce operational lifespan well before a bill reflects it.
What does industrial water testing cover across the plant?
From intake to discharge, one accredited partner for every stream.
Process & Boiler Feed Water
Hardness, salinity and mineral checks to prevent scaling and corrosion in equipment.
Cooling Tower Water
Microbial and salinity monitoring to control biofilm growth and equipment scaling.
Effluent & Discharge Water
COD and BOD analysis to confirm treated water meets CPCB/SPCB discharge limits.
Heavy Metal & Chemical Screening
Lead, cadmium, mercury and chromium testing for process and discharge streams.
STP/ETP Feed & Output Testing
Verifies treated water from your STP or ETP system is performing as designed.
Compliance Reporting
Structured reports formatted for CPCB and SPCB inspection or licence renewal.
What parameters cover plant intake to discharge?
Selected physical, chemical, organic-load and microbiological parameters for relevant industrial water and wastewater samples.
Physical & Chemical
Organic Load
Heavy Metals & Microbial

Industrial Water Testing FAQs
Industrial water testing evaluates water used in industrial processes, boilers and cooling towers, as well as wastewater from industrial operations. Depending on the application, testing may include physical, chemical and microbiological parameters such as pH, TDS, hardness, selected metals, COD and BOD.
Testing frequency depends on the water source, industrial application, treatment process, risk assessment and applicable regulatory requirements. Some facilities may require frequent monitoring, while others may follow periodic schedules. Confirm the appropriate frequency for your site rather than assuming that quarterly or biannual testing applies to every situation.
Applicable requirements depend on the water's intended use, industry, location and whether the sample is process water or wastewater being discharged. CPCB, SPCB and other relevant requirements may apply to specific discharge situations. Confirm the applicable limits and testing parameters for your facility.
Chemical oxygen demand (COD) measures the oxygen equivalent required to chemically oxidise substances in a water sample under the specified test conditions. Biochemical oxygen demand (BOD) measures the oxygen consumed by microorganisms while breaking down biodegradable material under specified conditions. Both parameters can help assess wastewater quality, but their interpretation depends on the sample and applicable requirements.
Industrial water testing may be relevant to food and beverage manufacturing, pharmaceuticals, textiles, paper and pulp, chemical processing, hospitality, healthcare and facilities operating shared industrial water or wastewater systems. The appropriate testing panel depends on the water application and the site's requirements.
Unsuitable water chemistry can contribute to scaling, corrosion and other operational problems in boilers, cooling towers and process equipment. Testing selected parameters can help businesses monitor water quality and investigate issues before deciding on corrective action.
Testing may be available for samples collected at relevant stages of an STP or ETP system, subject to the laboratory's scope. Confirm whether you need inlet, treated outlet or other process-stage testing, along with the applicable parameters and discharge requirements.
Reports are typically delivered within 3–5 working days. Actual reporting time depends on the parameters selected, number of samples or streams, sample requirements and laboratory workload. Confirm the expected timeline when enquiring.
The cost depends on the water type, number of parameters, selected testing panel, sample count and collection requirements. Contact our team for a quotation based on your facility's testing needs.
