Nearly $360 million of improvements were identified under the programme, including geographic information system and hydraulic system models; assessments, designs and masterplans for water and wastewater systems; and design and tender documents for networks, trunk sewers, and upgrades of the East Jerash and Tafilah wastewater treatment plants.
The project also developed designs and tender documents for two large projects currently under construction: the $25 million West Zarqa force main funded by the German public development financing organisation (KfW) and the $125 million Wadi Arab water supply system-II funded by the European Investment Bank (EIB) and the Agence Française de Développement (AFD). Additionally, construction management services supported $16.5 million worth of improvements, co-funded by USAID, to the Amman water transmission system to distribute water to various demand zones. Work converted parts of the supply system to gravity-fed, removing eight pump stations and generating $1.5 million in annual power savings.
A critical project objective was developing local capacity to perform water management and incorporating local preferences into project designs. CDM Smith led on-the-job training in GIS, modelling, design and masterplanning for local staff—building local engineering expertise to respond to vital future water sector needs. Because of these integrated and diverse project interventions, nearly 2.2 million Jordanians will benefit from upgraded wastewater treatment plants, improvements to water distribution systems and strengthened local capacity through 2035.
