The WASH Performance Index Report

  • The Water, Sanitation, and Hygiene (WASH) Performance Index is a comparison of country performance in realizing universal WASH. The WASH Performance Index assesses performance in the following components: water access, water equity, sanitation access, and sanitation equity.
  • The top five performing countries in the 2015 WASH Performance Index rankings are El Salvador, Niger, Egypt, Maldives, and Pakistan. The bottom five performers are the Dominican Republic, Gambia, Ghana, Samoa, and Timor-Leste.
  • Progress toward equity in sanitation is significantly associated with governance indicators including control of corruption, government effectiveness, regulatory quality, and rule of law. These results suggest the enabling environment for WASH contributes to progress in sanitation equity.
  • Water access performance among countries in Sub-Saharan Africa varies widely, despite their having the lowest water coverage in the world.
  • Among the world’s most populated countries, Pakistan, China, and Nigeria were top performers (ranked 5, 11, and 18 respectively). Russia, the Philippines and India were bottom performers (ranked 72, 83, and 92 respectively).
  • Despite the assumption that countries with higher GDP will perform better in improving access to water and sanitation, GDP was not significantly correlated with performance.
  • Among most top performing countries, neither water nor sanitation dominated the overall Index value, suggesting improvements in water or sanitation do not come at the expense of the other.

Thank you Antoine for this. Very interesting. The WASH PI is one of our indicators for nutrition in our Budget Support. Interesting to note a slow done in performance in Rwanda.

Do we know if the information used is all validated at country level?

Following up on the suggestion by Arnaud I recommend that we discuss, in those countries with an active water sector coordination forum / platform, the findings of the WASH Performance Index Report, and report to this group how accurate the WASH PI has been for each specific country. In addition please can you discuss in your country also how the WASH Performance Index can have implications for policy, decision-making, advocacy, accountability, human rights, and WASH investment targeting?

Dear Sjaak,

Good idea to have a discussion on the use of the index. On our side, it will not be fully in use before 2018! But we expect that the index will help in having a better appreciation of progresses made and equity in the sector. The first results also already have shown huge urban-rural divide, for instance on the hygiene side: form 0.32 to 0.66. Useful to better target policy dialogue and investments.
