Water Sector Regulation

When seeking to involve the private-sector in water and sanitation infrastructure projects, a host country's legal framework should be considered.  Regulation of the sector (including regulation of tariffs, performance and standards) is important for all service delivery, whether provided by the private or public sector.  Regulation of tariffs and regulatory risk that this carries are crucial to PPPs in the water sector.


Whilst every regulatory mechanism is unique to the country and framework within which it operates, most models of economic regulation of the water sector fall into one of four major categories.  Click on each of these categories to find a summary of the framework, examples and reference materials:


Sample Water Laws and Regulatory Bodies

See below sample legislation and regulation on water & sanitation where private sector participation is envisaged, together with links to regulatory bodies:




 Laws setting out the basis for delegation of public service functions of water and sewerage services and establishment of CAM Water - Loi No 98-005 du 14 Avril 1998 portant regime de l’Eau (framework)



  • Kenya Water Act 2002 - The Act provides for the decentralisation of powers from the national to the regional and local level; the separation of water resources management from water and sanitation service delivery, as well as the institutional separation of policy, regulatory, asset holding and operational functions. Following the provisions of the Act, the transfer of asset ownership from the Water Ministry and the National Water Corporation to seven regional Water Services Boards (WSBs), and most local governments have handed over their assets to the WSBs. While the WSBs are in charge of asset development and bear overall WSS service responsibility within their areas of jurisdiction, they appoint Water Services Providers (WSPs) to actually provide the service.  In urban areas WSPs are mostly local authority-owned utilities that have been established as commercialised, publicly owned companies.  In rural areas community-managed projects are being transformed into formally recognised WSPs.  The Water Services Regulatory Board has been created to supervize water services provision.
