Implementation of SEEAW The experience of Tunisia Amman, 10-13 March 2008

1. Implementation of SEEAW The experience of Tunisia Amman, 10-13 March 2008 Joint MEDSTAT II / UN-ESCWA Training course on Water accounts Cécile Roddier-Quefelec

2. TUNISIA : water issue Semi-arid country Low water resources (less than 450 m3/inh/year , expected to be 350 m3/inh/year in 2030) High variability of the water resources in time and space Less than 50 mm in the extreme south More than 1500 mm in the extreme north-west 56% surface water (in the North) 44% ground water (of which 15% are non-renewable water resources) (in the south) High losses during distribution

3. Tunisian situation Water law Different water price (Social to high consumers) Integrated water resource management Development of a national water information system (SINEAU) Good availability of water data Lack of data on Return water Water consumption for irrigation Soil water DBO per activity branch Cost of water per activity branch Expenditures and investment for water distribution and treatment

4. Tunisian situation : development path Water accounts includes in the 2008/2009 National Statistical Plan Training course on SEEAW, Tunis, October 2007 Technical assistance mission, December 2007 National Statistical Office initiated first work in December 07 and started to populate an adapted PSUT Meeting between INS and Water Resources General Directorate: objective to sign a cooperation protocol Need to mobilise numerous actors: INS, DGRE, DGBTH, SONEDE, ONAS, DGGR, DGDA, SECADENORD, ANPE, DGACTA, INAT Propose to create a national committee for water statistics and accounts , to be included in National statistical Committee : presentation of the draft tables, discussions and setting-up work programme and sharing of responsibilities

5. Tunisia : implantation plan First phase Physical Supply and Use Tables Assets and hybrid accounts (monetary part may be difficult, actualisation methods) Second phase develop Emissions accounts Flow of Water (complementary) Quality accounts (degree of salinity) Expenditures accounts may be envisaged as well

6. Physical use table (not complete)

7. Physical supply table (not complete)

8. Example of water circuit (households) Eau de source Eau de pluie Puits (Consommation) Eau potable SONEDE (Consommation) Ménages raccordés SONEDE et ONAS Ménages raccordés SONEDE mais non ONAS (Consommation) Ménages non raccordés SONEDE Ruissellement urbain Assainissement autonome Pas de traitement Pas de traitement eau du sol STEP ONAS aquifère eau du sol Pas de traitement réutilisation oueds ou mer oueds ou mer aquifère

9. Tunisia : conclusion Lot of data available Compilation of data allowed to identify quality problems in the available water statistics (revision of the JQ data) New data collection to be organised by INS at the partners (up-date and clarifications of production methods) Calculation methodology may be a problem Institutional framework for environment statistics and accounts need to be clarified Environment statistics being not legally part of the NSI’s tasks, but no other national institution has received this assignment
