The International Standards Organization (ISO) has just published three standards providing guidelines for service activities relating to drinking water supply systems and wastewater sewerage systems. These international standards are designed to help water authorities and their operators to achieve a level of quality that best meets the expectations of users and the principles of sustainable development.
ISO 24510, Activities relating to drinking water and wastewater services – Guidelines for the assessment and for the improvement of the service to users
ISO 24511, Activities relating to drinking water and wastewater services – Guidelines for the management of wastewater utilities and for the assessment of wastewater services
ISO 24512, Activities relating to drinking water and wastewater services – Guidelines for the management of drinking water utilities and for the assessment of drinking water services
The standards, which aim to provide relevant stakeholders with guidelines for assessing and improving services to users, and with guidance for managing water utilities, will have now to be adapted to national or regional contexts. A strong orientation towards developing countries was taken by the ISO with the creation of an ad hoc group, lead by Morocco, order to support developing countries in the application of the standards and a first trial of the standards has been launched in some African countries.
