The project is located in Sakaka Governorate, Al-Jouf Region, and aims to develop and strengthen the wastewater infrastructure in accordance with approved plans and specifications. The scope of the project includes the construction of main and secondary sewer lines, a pumping station, and a discharge line, along with earthworks and surface restoration. The project involves the installation of HDPE pipelines with diameters ranging from 200 to 630 mm, totaling approximately 207,109 meters, and concrete pipelines lined with polyethylene with diameters from 700 to 1,400 mm, totaling around 17,044 meters, in addition to thrust boring works for pipes ranging from 200 to 1,400 mm with a total length of approximately 900 meters. The project also includes a 90 mm HDPE discharge line of approximately 100 meters, the construction of 2,558 circular concrete manholes with depths varying from less than 2 meters to more than 10 meters, and the supply and installation of 720 PVC-U clean-outs at the beginning of the lines. Furthermore, the project covers the connection of new networks to existing systems, relocation and transfer of existing service lines, installation of chambers, valves, and fittings, as well as the construction of a fully integrated pumping station including all civil, mechanical, electrical, and architectural works in accordance with the contract documents.
