About This Project

• This project comes after years of conflict and widespread destruction that damaged Darya’s infrastructure, leading to significant population displacement and severe public health deterioration. With displaced families gradually returning, rehabilitating the sewage network has become an urgent necessity to reduce environmental pollution and prevent waterborne disease outbreaks.

• Improve living and environmental conditions for residents
• Build infrastructure resilience and accommodate returnees
• Support sustainable and safe return of displaced families

Scope of Work

• Pipe Replacement and Rehabilitation: Removing damaged pipes and installing new HDPE & PVC pipes
• Network Cleaning and Venting: Cleaning existing lines of sediment and blockages, rehabilitating ventilation points
• Installation and Rehabilitation of Manholes (Rikarat): Constructing new concrete manholes or repairing existing ones
• Construction of New Sewer Gravity Mains and Branch Lines: Executing the installation of a new primary sewage collection line extending 1,500 meters in length with a diameter of 800 mm, where branch lines totaling 600 meters in length with varying diameters of 300 mm and 400 mm shall connect into the primary line, which ultimately discharges to the final outfall point

Expected Impact

• Direct improvement of living conditions for over 100,000 residents in Darya and surrounding areas
