The project is an integral part of an overall wastewater reuse system, which envisages enhancing the quality of wastewater to enable its use for agricultural irrigation in three Wastewater Treatment Plants (WWTP), in the Northern Governorate of Jordan.
The project aims to  increase the proportion of treated wastewater and consequently promote food security and sustainable agriculture
The overall development objective is to contribute to the Jordanian efforts in achieving climate change mitigation and resilience, while ensuring efficient and sustainable water resource management through:

  • Ensuring that the operation and maintenance of the 3 WWTPs is done in a cost-efficient and sustainable manner.
  • Targeted capacity building for Yarmouk Water Company (YWC) staff in sanitation related activities as well as improving the institutional capacity on climate change mitigation and adaptation in order to guarantee that the Jordanian Effluent Standards are achieved and the defined Key Performance Indicators (KPIs) are fulfilled.
