Wastewater Verification

Wastewater Verification under ISO 46001:2019 – Water Efficiency Management Systems provides independent assurance that your wastewater data, performance indicators, and efficiency claims are accurate, credible, and ready to be trusted.

What We Verify

Our wastewater verification typically covers:

  • Wastewater flow measurements and monitoring systems

  • Data collection methods, records, and calculations

  • Water balance and wastewater mapping

  • Treatment efficiency and reuse practices

  • Compliance with internal objectives, regulatory requirements, and ISO 46001 criteria

  • Claims related to wastewater reduction, reuse, or efficiency improvement

  • Verification is conducted against ISO 46001 requirements and other applicable regulatory or client-defined criteria.

Verification Approach

The verification process includes:

  • 1

    Review of documented information and wastewater management plans

  • 2

    Assessment of monitoring and measuring equipment and data integrity

  • 3

    Water balance and wastewater mapping

  • 4

    Evaluation of operational controls related to wastewater generation and treatment

  • 5

    On-site verification and interviews with responsible personnel

Independent assessment of wastewater performance indicators and reported results, The outcome is a clear, structured verification conclusion supported by objective evidence.

Benefits of Wastewater Verification

  • Increased confidence in wastewater data and performance claims
