This article has been given a rating which conflicts with the project-independent quality rating in the banner shell. Please resolve this conflict if possible.
Information about the following topics could be added to further improve the article:
The functioning of user associations in rural areas
Water quality, especially concerning the extent to which slightly brackish groundwater is used for drinking water supply in some regions of the South
The incidence and impact of drought and floods, as well as measures to mitigate their impact
Water use:This section is about overall water use, not drinking water use. Overall water use should rather be dealt in a new article on water resources management in Tunisia.
The functioning of wastewater treatment plants, in particular concerning the compliance with discharge standards and the disposal of sludge
The history section is brief and focused on the development of infrastructure. A history of policies, institutions and laws is still missing.
An updated water tariff (the one shown is from 2001)
Sanitation tariffs charged by ONAS
Water tariffs in rural areas outside the service area of SONEDE
Actual investment figures, as opposed to planned investments listed in the 5-Year-Plans
Desalination projects, both for seawater and brackish water
Average monthly water and sanitation bills, both in absolute terms and as a share of household expenditures, to measure affordability of tariffs
Information on bilateral external cooperation, in particular by France and Germany.

Add more primary sources. Currently, some basic information is quoted from secondary or tertiary sources that almost certainly have taken this information from other sources, with or without referencing it.--Mschiffler (talk) 21:54, 21 March 2010 (UTC)[reply]
