ERWAT Scientific Services operates an ISO/IEC 17025–accredited laboratory, certified by the South African National Accreditation System (SANAS). The laboratory provides reliable, high-quality analytical testing services that support ERWAT’s operational mandate and serve both public and private sector clients.

The laboratory is equipped with modern infrastructure, automated systems, and skilled technical staff. It offers a wide range of routine and specialised testing services across multiple water and wastewater matrices, including potable water, wastewater, sludge, and treated effluent. These services support regulatory compliance, environmental protection, and public health.

Advanced analytical techniques, such as gas chromatography–mass spectrometry (GC-MS) and real-time polymerase chain reaction (PCR), allow the laboratory to go beyond standard testing. This enables the detection of organic pollutants, emerging contaminants, and waterborne pathogens, ensuring accurate and defensible results.

With the capacity to process high sample volumes, ERWAT Scientific Services delivers fast turnaround times without compromising quality. Comprehensive sampling, analysis, and reporting processes ensure results are timely, consistent, and aligned with national standards.

In response to growing challenges such as urbanisation, climate change, and resource constraints, ERWAT uses its scientific expertise to fulfil its core wastewater treatment mandate for the City of Ekurhuleni, while also strengthening innovation, resilience, and sustainability across the water sector.
