News TUNISIA: Reusing wastewater to irrigate green spaces

Wastewater from the Tunisian capital will soon be reused. It is the meaning of the agreement that was recently signed between Tunisia’s National Sanitation Office (ONAS) and the Tunis Bay Project Company, the company created for the implementation of a major real estate project in Tunis. The project involves the construction of a new city to be called Tunis Bay.

The new city will be established on an area of 523 hectares, 35 minutes from the centre of the Tunisian capital. Tunis Bay will be dotted with green spaces and will have a golf course, residential and commercial units, a business centre, a private hospital, a university and a technology centre. The agreement signed between Tunis Bay Project Company and ONAS provides for the use of treated wastewater for watering the green spaces and the golf course of Tunis Bay, which will have 18 holes.

The wastewater treated for reuse by the city of Tunis Bay will come from wastewater treatment plants in the northern area of Greater Tunis. Among these facilities, the Charguia wastewater treatment plant will have a capacity of 60,000 m³ of water per day. The Tunisian government is also planning to rehabilitate the pumping station for the return sludge from the Charguia wastewater treatment plant.

Tunis Bay Project Company and ONAS have not provided further details on their partnership, particularly concerning the improvement or not of the level of water treatment which will thus be used to water the green spaces of Tunis Bay. However, Tunis Bay plans to withdraw 4,000 cubic metres of wastewater per day for the maintenance of its green spaces.
