CDM Smith provided construction supervision and contract administration for the C762 D Line TSE Pumping Station and Transmission Main project in Doha, Qatar. The team delivered a large-scale wastewater reuse system, including a high-capacity pumping station and extensive transmission pipeline. Services included review and approval of construction shop drawings, materials/equipment and method statements, site supervision, commercial, QA/QC, and HSE management. Through structured project controls, progress monitoring and coordination across stakeholders, CDM Smith ensured quality delivery, schedule adherence, and compliance with technical and safety standards.
The project includes construction of a major TSE pumping station with a discharge capacity of 120,000 m³/day and total dynamic head of about 15 bars, supporting the conveyance of treated sewage effluent for reuse and irrigation across key fodder farmlands.
Works involved approximately 65 km of DN1200 transmission main, connecting the Doha South Sewage Treatment Works to Al Ghadeer & Hassad Farms and onward to a seasonal storage lagoon, forming a critical component of the water reuse network.

The project required microtunneling of approximately 4 km at major crossings and intersections, enabling safe and efficient installation of pipelines within constrained urban and utility corridors.
Scope included installation of switchgear, transformers, HVAC, surge protection vessels, firefighting systems, SCADA and low-current systems, ensuring full operational capability of the pumping station and supporting infrastructure.
The C762 D Line TSE Pumping Station and Transmission Main project is a key infrastructure development in Doha enabling sustainable water reuse for irrigation systems and sand washing supply. Commissioned by the Public Works Authority (Ashghal), the project includes construction of a high-capacity pumping station with a discharge capacity of 120,000 m³/day at 15 bars head and approximately 65 km of 1200 mm diameter transmission pipelines extending from the Doha South Sewage Treatment Works to Al Ghadeer & Hassad Farm, sand washing plants and a seasonal storage lagoon. The work also involved microtunneling at critical crossings and installation of mechanical, electrical, and utility systems to support operations. CDM Smith provided construction supervision, contract administration and project controls, overseeing site activities, reviewing materials and method statements, and ensuring compliance with quality, health, safety and environmental standards. Through effective coordination and performance monitoring, CDM Smith supported the successful delivery of a complex system that enhances water reuse and long-term infrastructure resilience in Qatar.
