The German government funded the Madaba management contract, together with the MWI and the WAJ, as part of an effort to enhance the management of wastewater treatment plants. For capital investments, donor funding has proven to be pivotal to attracting private financing. An innovative funding structure that combines private, local and central government, and donor financing was put in place for the As Samra BOT contract, combining 46% of funding from USAID, 45% from the private sector, including a consortium of banks and the project special purpose vehicle, and 8% from the government of Jordan (Degremont, n.d.).
