What is ISO 24526?

ISO 24526 is officially titled:

β€œService activities relating to drinking water supply, wastewater and stormwater systems β€” Guidelines for the management of wastewater utilities and for the assessment of wastewater services”

This standard provides management principles, performance indicators, and evaluation criteria for wastewater utilities, covering all activities related to collection, transport, treatment, and discharge of wastewater. It offers a holistic framework that integrates:

  1. Sustainable Development Goals (SDGs)
  2. Risk management principles
  3. Regulatory compliance
  4. Environmental protection
  5. Service quality and customer satisfaction

It is designed for use by public and private wastewater service providers, including urban utilities, municipal bodies, and industrial wastewater operators.
