  • Can greywater be reused in Tunisia?
  • Some Tunisian Experiences of Greywater Treatment Greywater constitutes a major part of domestic wastewater. If properly valued and treated, these waters can be a resource for a variety of uses. We tried to evidence some examples of Tunisian experiences that opted for greywater treatment and reuse with successful results.
  • What is greywater reusability & recycling?
  • Greywater reuse has been proposed to expand local water supply portfolios while minimizing stress on existing ecosystems and infrastructure. Researchers have developed several technologies for greywater reusability and recycling. There are three primary treatment technologies for greywater treatment: physical, chemical, and biological.
  • Are greywater reuse systems a viable alternative to large-scale water treatment systems?
  • Implementing large-scale water treatment and distribution systems can be expensive. Greywater reuse systems, which can be more straightforward and less costly to set up, offer a more financially feasible option for water recycling and transition to circular economy ( Ghisellini and Ulgiati, 2025 ).
  • Which countries use treated greywater for irrigation?
  • In many regions of the world, particularly where the water sources are unavailable, the economic incentive to reuse is substantial. For example, in countries such as Kuwait, Italy, Spain, Malta, Germany, Jordan, or USA, treated greywater is already used for irrigation .
