Water Quality Assessment Report - ZAI: Task 3 – Zai Water Treatment Plant Project

for the United States Agency for International Development. The report assesses the raw and treated water quality of the Zai Water Treatment Plant, which serves the Wadi Arab Water System II in Jordan. The report begins with an introduction to the project, which includes a summary of the USAID Jordan Water Infrastructure program and the scope of work for Task 3, the expansion of the Zai Water Treatment Plant. The report also acknowledges the contributions of various stakeholders, including the Ministry of Water and Irrigation and the Water Authority of Jordan. The report is organized into four sections. Section 2 provides an overview of Jordanian water quality standards, including physical, biological, and chemical characteristics of drinking water. The report outlines the standards for turbidity, total organic carbon, coliforms, and other parameters. Section 3 assesses the raw water quality of the KAC source water to the Zai Water Treatment Plant. The report presents data on turbidity, total organic carbon, coliforms, and other parameters, and compares the results to historical data. The report also discusses the impact of extreme water quality events on the raw water quality. Section 4 assesses the treated water quality of the Zai Water Treatment Plant. The report presents data on turbidity, total organic carbon, chlorine, chlorite, and other parameters, and compares the results to historical data. The report also discusses the performance of the water treatment plant and the effectiveness of various treatment processes. The report includes several figures and tables that illustrate the raw and treated water quality data. The figures show the turbidity and total organic carbon levels in the raw and treated water, while the tables present the data in a more detailed format. The report concludes that the Zai Water Treatment Plant is generally meeting the Jordanian water quality standards, but there are some areas for improvement. The report recommends further monitoring and evaluation of the raw and treated water quality to ensure that the plant is operating within the required standards. The report also includes an appendix that provides additional information on the Wadi Arab Water System II and the Zai Water Treatment Plant. The appendix includes a water quality assessment memorandum from 2014 that provides background information on the plant's operations and water quality. Overall, the report provides a comprehensive assessment of the raw and treated water quality of the Zai Water Treatment Plant and identifies areas for improvement. The report is a valuable resource for stakeholders involved in the management and operation of the plant, and for policymakers and regulators who are responsible for ensuring that the plant meets the required water quality standards.
