This project aims to enhance and expand wastewater services in Al-Muzahimiyah Governorate in line with urban and population growth, contributing to improved service quality for beneficiaries and supporting the objectives of Saudi Arabia’s Vision 2030. The scope includes the implementation of a comprehensive sewerage network comprising main and secondary lines constructed from high-density corrugated HDPE pipes with diameters ranging from 200 mm to 1200 mm, along with concrete manholes and PVC-U cleanouts at the beginning of the sewer pipes to ensure optimal network performance. The project also involves the construction of a wastewater pumping station to support the network and improve flow efficiency. Overall, the project will significantly enhance the performance of the sewerage system, elevate service standards, and promote sustainable urban development in Al-Muzahimiyah Governorate.
