Diagnostic and Rehabilitation Feasibility Study of AlThawra Drinking Water System

The Al Thawa Drinking Water System can supply drinking water to approximately 900,000 beneficiaries at its total operational capacity, 80% of the Daraa Governorate population of 1.2 million people. Only 330,000 beneficiaries were receiving water from Al Thawa DWS, primarily due to damage caused to many of the infrastructure components during the crisis in Syria. As a mitigation measure, and in areas where no or little water was received from the Al Thawra DWS, beneficiaries were getting water from boreholes or relying on water supplies from water delivery trucks. This project, therefore, produced a feasibility and rehabilitation study of Al Thawra DWS to inform the reconstruction process.

The objective was to inform the reconstruction process and capacities of Al Thawra Water Supply System while producing a feasibility and rehabilitation study.

• Undertaking a comprehensive rehabilitation study of the Al Thawra Drinking Water System:

– The Al Thawra Drinking Water System is one of the most significant and critical water supply projects in Syria’s Daraa Governorate, and it is divided into six supply areas (0-5).
– Total length of distribution mains: ca. 222 Km (DN 100-700 mm)
– Pumping stations, including booster stations, total number: 53 stations
– Ground storage tanks: 8 tanks with an average volume of 3,250 m3
– Transformer and generator stations powering the system: a total of 12 transformer stations (average 800 KVA/ max. 2000 KVA) and 11 generator stations (average 890 KVA/ max. 2000 KVA)
– Water delivery under optimal operational conditions: up to 12,581 m³/h of drinking water

• Undertaking a diagnostic of the current functioning of the system components;
• Setting priorities related to repair, replacement or potential upgrading that may be required, including a detailed design for each rehabilitation project, including calculations, drawings and specifications, and a detailed bill of quantities for each rehabilitation project;
• Identify and prioritise multi-year plan interventions for implementation based on risk approach;
• Submitting a report related to capacity building and support to operations, including analysis and critical review of O&M processes.
