Eau et assainissement (Anglais)

Almost fifty percent of the developing world’s population - 2.5 billion people – lack improved sanitation facilities, and almost 1 billion people still use unsafe drinking water sources, and even those with access often receive unsafe and inadequate service. Sustainable Development Goal 6 on Clean Water and Sanitation, by 2030, sets tough targets:

  • 6.1 achieve universal and equitable access to safe and affordable drinking water for all
  • 6.2 achieve access to adequate and equitable sanitation and hygiene for all
  • 6.4 substantially increase water-use efficiency across all sectors.

Water is also crucial to food security and irrigation, and is affected by climate change. In an infrastructure-intensive sector, improving access and service quality to meet the SDGs cannot be done without massive investment. Around the developing world, the water sector is chronically under-funded and inefficient. In this context, Public-private partnerships (PPPs) can be a mechanism (among others) to help governments fund much needed investment and bring technology and efficiency that can improve the performance and financial sustainability of the water sector.

Governments are using in the water and sanitation sector increasingly to finance and operate bulks water supply and wastewater treatment. Governments turn to PPPs to introduce new technology and innovation where traditional sources are being scarce, such as in desalination and water reuse. Utilities are drawing on specific expertise, such as non revenue water reduction and pressure management, to bring efficiencies and service improvements. Private investors and providers are increasingly local and regional, increasing competition and bringing down prices.

A key challenge in sustainability of the sector is customer tariffs. Water utilities have difficulty investing in infrastructure and maintaining it when they cannot rely on revenue streams that cover the costs of operation and investment. Whilst subsidies and grants from government continue to play an important role in financing water and wastewater infrastructure, a stable revenue stream is more dependable and allows utilities to carry out business and asset planning.
