The technical management of drinking water includes components relating to: (i) securing the water supply using the national water transfer system and the SONEDE regional interconnections networks; (ii) improvement of control systems in supply networks and tanks, and introduction of automatic management systems in extended networks; (iii) generalization of the counting system at the subscriber level; (vi) fight against network losses and leakage with improved materials, rehabilitation of dilapidated networks, pressure regulation in the appropriate areas and implementation of networks audit and leaks campaigns. These actions have had a positive impact on some of the networks technical performances. However, the overall network performance, which reached 81.4% in 2000, its highest index in the history of the national company, has declined since then, reaching 76.2% in 2010 and 70.7% in 2015. It is true that the produced water volumes have doubled over the same period.

About drinking water savings, they have long been perceived only through SONEDE direct actions on its networks or by the impact that its tariff system could have on the customers’ behaviour. Individually, these measures are likely to prove insufficient if we really want to tackle water conservation, which is really at the uses level where a vast pool of water savings still needs to be explored and valued. We can evoke in this way the following actions:(i)Technological innovation in the field of domestic water by imposing efficient standards and guidelines for local manufacturing and imported equipment.
