Saudi Arabia launched a large-scale sewage treatment plant construction project with a total investment of 90 million Saudi riyals (about 24 million US dollars) on August 11. The project is located in Saudi Arabia, covering an area of about 170,000 square meters, and will be built into a modern environmental protection facility integrating sewage treatment, reclaimed water reuse, sludge treatment and other functions, and is expected to significantly improve the level of local water resource recycling after completion.

As an important part of Saudi Arabia's Vision 2030 water sustainability strategy, the project adopts international advanced wastewater treatment technology and strictly complies with the requirements of the Saudi National Water and Agricultural Resources Authority (NWRA) and the Pollution Control Regulation (PPCA). The project pays special attention to environmental compliance design, including the adoption of high-standard anti-seepage engineering and the construction of comprehensive sludge treatment facilities to ensure that the effluent quality meets strict local discharge standards.

The project cost consulting work makes full use of BIM technology to accurately measure the special structure of the sewage treatment plant. Focus on core treatment facilities such as biochemical reaction tanks and sedimentation tanks, as well as underground pipe network systems up to several kilometers to carry out refined engineering quantity accounting. At the same time, combined with Saudi Arabia's local architectural style and environmental protection requirements, detailed planning is carried out for the decoration and decoration projects of supporting buildings such as management rooms and equipment control centers.

It is worth noting that the project was designed and constructed with the special climatic conditions of Saudi Arabia fully taken into account. In view of the local environmental characteristics such as high temperature and strong wind and sand, key parameters such as concrete impermeability level and pipeline anti-corrosion layer thickness are specially strengthened in the calculation of engineering quantities to ensure the long-term stable operation of the facility.

After the completion of the project, it will not only effectively alleviate the local water shortage, but also create a large number of jobs and drive the development of Saudi Arabia's local environmental protection industry. The project pays special attention to localized procurement, giving priority to the selection of local environmental protection equipment and building materials in Saudi Arabia to promote the improvement of the environmental protection industry chain.

Industry experts said that the project is an important achievement of cooperation between China and Saudi Arabia in the field of environmental protection, which not only draws on China's rich experience in the construction of sewage treatment plants, but also fully combines the actual needs of Saudi Arabia, providing a successful example for green infrastructure construction cooperation under the framework of the "Belt and Road". The advanced technology such as the prefabricated sewage treatment tank adopted in the project is expected to reduce the project cost by 15%-20% and improve the construction efficiency, showing the broad prospects of China-Saudi environmental protection technology cooperation.(This article is from the official website of Jiandao www.seetao.com it must not be reprinted without permission, otherwise it will be investigated, please indicate the reprint of Jiandao.com + original link) See the Middle East column editor/Gao Xue
