Doha: The Public Works Authority 'Ashghal' announced the completion of main works for the Design and Build Project for the TSE Seasonal Storage Lagoons - Phase 1.
According to Qatar News Agency, the project is part of Ashghal's efforts to promote environmental sustainability and optimize the use of treated water and renewable water resources, aligning with Qatar National Vision 2030. The project engineer from the Drainage Networks Projects Department at Ashghal, Eng. Waled Al Ghoul, stated that the first phase included constructing five reservoirs (lagoons) with a total storage capacity of 22.5 million cubic meters, alongside an evaporation pond with a capacity of 8.7 million cubic meters. These reservoirs will receive treated water from the Doha South Sewage Treatment Plant via the rising main (D-Line).
Eng. Waled Al Ghoul explained that the project aims to balance the usage of treated water quantities produced throughout the year. Surplus water is stored during the winter for reuse during the summer months when demand for treated water increases for irrigation, ornamental plants in public parks and roads, and for supplying fodder farms. The treated water can also be utilized in cooling systems and dust control at work sites.
Eng. Waled highlighted Ashghal's commitment to implementing construction practices that enhance environmental sustainability within the project. Over 8 million cubic meters of recycled excavation materials were reused to construct the storage lagoons, reducing resource waste. The project also contributes to providing an attractive environment for migratory birds such as pink flamingos and plovers.
The project included constructing a 6 km access road and a 25 km-long internal road network. A total of 8 km of water pipelines were laid, incorporating the necessary hydraulic components for supplying the reservoirs and transporting water between them. Additionally, 8 buildings were constructed for operation and maintenance, along with electrical substations and other facilities.
It is notable that Ashghal achieved 10 million man-hours without a lost-time injury (LTI) during the first phase of the project, which included deep excavation works at depths of up to 10 meters below the ground, reflecting the authority's commitment to applying the highest standards of occupational safety and health throughout all stages of implementation.
