Water
Consumption, Tariffs and Regulation aims to provide a statistical overview
of water abstraction, consumption, tariffs and data on sewage and wastewater
treatment at an international level. It is mainly based on the statistical
information provided by the IWA Specialist Group on Statistics and Economics.


The
book is structured in three main parts. Part I presents tables and figures
relative to water consumption and sanitation status and focuses on water
abstraction, water delivered, water consumption and the evolution of sewer
connection and wastewater treatment.


Part
II focuses on the analysis of water tariffs by investigating the structure of
water tariffs by analysing the importance of the variable and fixed charge. It
presents drinking water tariffs and illustrates the relationship between tariffs
and GDP and also the size of the cities. Finally, charges in wastewater are
dealt with country by country.


Part
III analyses the main aspects relative to water regulation and describes the
importance of private operators in the management of the water cycle.
Information relative to the principles used to fix drinking water prices is
presented with an assessment of access to public water services.
