Water distribution
|
The quantity of distributed water in 2007 amounts to 417 million cubic meter. The storage capacity is around 1.000.000 m3. The distribution network is 35.000 km long. The quantity of water that has been billed amounts to 345 million m3. |

 Water conservation
The water conservation strategy that SONEDE is implementing is based on a set of measures related to technical, organisational and financial aspects.
The technical aspect is very important in this strategy. The actions which are carried out in this framework basically deal with the control of network technical management, the detection and repairing of pipe leaks and the generalisation of the use of corrosion-resistant equipment.
At the organisational level, regional structures have been set up to ensure the follow up of actions. Night and day duty teams are mobilised to intervene to repair ruptures and leaks of pipes.
The financial aspect is concretised by controlling drinking water demand through an adequate tariff system.
Consciousness raising campaigns for water conservation are carried out through mass-media an direct contact.
Training courses are periodically organised for the personnel in charge of water equipment maintenance.
Drinking Water Supply
99,1 % of the Tunisian urban population are connected to the drinking water network in 2007. In rural areas, 46,7 % of the population are supplied from the network of SONEDE and 45,4 % from the network of the General Direction for Rural Engineering which corresponds to a global rate of 92,1 % against 31 % in 1987. This progress is the result of the impulse of the President of The Republic Zine El Abidine Ben Ali to the rural water sector through national and regional development programmes including the Presidential Programmes and those of the National Solidarity Fund (FNS 26-26).
Network efficiency
In 2007, the adduction network efficiency is 92,2 % and the distribution network one is 83,4 %, which corresponds to a global efficiency reaching 77,3 % against respective rates of 93,3 % and 78,4 % in 1994.
Water conservation, which constitute one of the axes of the national strategy for water resource mobilisation for the decade 1990-2000, has considerably contributed to improving network efficiency.
Water quality
The distributed water undergoes a double bacteriological control by the relevant services of SONEDE and the Public Health Ministry. The results of tests are in accordance with the recommendations of the World Health Organisation (WHO).
The quality of the water distributed in the South - East of Tunisia has been improved thanks to the achievement of the brackish wate desalination plants of Gabes, Zarzis and Djerba, ordered by his Excellency the President who has constantly shown interest in the living conditions of citizens and was always keen to ensure a good quality drinking water.
The central laboratory of tests is accredited ISO 17025. |
