Jordan faces many challenges related to its water resources due to its climate, population growth, and limited renewable supplies. Groundwater is overexploited in many basins, with abstraction exceeding safe yields. Actions taken to address illegal wells have included confiscating drilling equipment and strengthening penalties. The SWIM-Sustain Water MED project aims to demonstrate sustainable wastewater management and reuse technologies through pilot projects in four countries to assess impacts and inform policies. The Jordan pilot establishes a decentralized wastewater treatment unit at a building to reuse water.
