AquaRating focuses the challenges water and sanitation services providers face in a comprehensive way, evaluating their performance through indicators and management practices, establishing an international standard, and relying on information verified by independent auditors accredited by the AquaRating Entity. The basic goal of the rating system is evaluating the water and sanitation services in an integrated way through 112 assessment elements organized in 8 areas, providing a rating in each one of them – as a result of rating each and every single of their compounding elements – to get aggregated in a unique mark (from 0 to 100, and called AquaRating) for the utility. This way, AquaRating avoids the simplistic message of the single rating, allowing at the same time having a quick view of the utility areas with improvement potential.

The International Water Association (IWA) is a global reference point for water professionals, spanning the continuum between research and practice, and covering all facets of the water cycle. Through its network of members and experts in research, practice, regulation, industry, consulting and manufacturing, the IWA is in a better position than any other organization to help water professionals create innovative, pragmatic and sustainable solutions to challenging global needs.

The strength of the IWA lies in the professional and geographic diversity of its membership — a global mosaic of national, corporate and individual member communities. Its members are leaders in their field and represent:

  • Researchers - where solutions begin;
  • Utilities - managing water services worldwide;
  • Consultants - connecting problem owners with solution providers;
  • Industry - creating sustainable water solutions;
  • Regulators - safeguarding public health; and
  • Equipment manufacturers - translating ideas into products.

The IWA network is structured to promote multi-level collaboration among its diverse membership groups, and to share the benefit of knowledge on water science and management worldwide. The Association helps make the right connections at the right time, thereby sharing cutting-edge research and practice that allows the water sector shape its future.

The Inter-American Development Bank (IDB) and the International Water Association (IWA) have developed a rating system that assesses the performance of water and sanitation service providers. As part of a comprehensive rating of the provider, the system also offers detailed assessments of its various rating areas such as access to services, quality of services, operational efficiency, planning & investment efficiency, management efficiency, financial sustainability, environmental sustainability, and corporate governance. In addition, AquaRating provides an assessment of the reliability of the information provided, as well as recommendations to improve management practices.

The expected benefits of AquaRating are:

  • Service providers
    • Receive a comprehensive performance rating from a third party which will contribute to the overall reputation of the provider, increase its accountability, open access to new markets and finance, and attract new qualified staff.
    • Identify areas of improvement and receive recommendations.
    • Access a knowledge and assessment community that fosters continuous learning.
  • Governments, regulators and development agencies
    • AquaRating can be used to stimulate providers to maintain or improve their performance.
    • AquaRating can help target technical assistance, incentives and finance according to providers’ performance.
  • Consumers
    • The use and implementation of AquaRating recommendations will lead to better services in terms of quality, efficiency, sustainability and transparency.
