  • A brief description of the components of the service relating to the users;
  • Core objectives for the service, with respect to users’ needs and expectations;
  • Guidelines for satisfying users’ needs and expectations;
  • Assessment criteria for service to users in accordance with the provided guidelines;

Access to water is a basic human right. So says the United Nations whose ambitious Millennium Development Goals aim to improve access to drinking water and wastewater services throughout the world by 2015. Supporting this endeavour, ISO has developed a series of standards on drinking water and wastewater services that provide a common methodology for assessing the services provided by water utilities of all types and sizes worldwide.

Developed by ISO technical committee ISO/TC 224 for quality water supply and wastewater services, ISO 24510 and its sister standards ISO 24511 and ISO 24512 are intended promote dialogue and continued improvement within the water service itself and among all its stakeholders - the owners, the regulators and the users.
