People living in Nouakchott drink now from Aftout Es Sahili:

The authority has just succeeded an outstanding operation which aims at providing Nouakchott inhabitants with drinkable water from Aftout Es Sahili instead of Idini. In fact, for the last decade Nouakchott was in shortage of clean water and a real solution was needed. The current project is expected to solve the lack of clean water in the capital for the next century. Moreover it will help people avoid water borne diseases and its disastrous impact on children life.
Without overstating I can say that the current water is better than the previous one and the reason is that I never heard anyone until today (more than three weeks after its release in the taps) complaining genuinely about its quality.
