The Onas pilot privatization programme will delegate wastewater management in several cities in the North African country to improve on efficiency. In the pilot privatization program, Onas will franchise collective sanitation in Greater Tunis and the governorates of Gabès, Médenine, Sfax and Tataouine.

The franchise in Greater Tunis will include a 1,240 km wastewater collection network serving 231,000 public service subscribers. The contract will see the prospective operator resume responsibility for 52 pumping stations and a 40,000 m³ per day wastewater treatment plant.
