Waste Water Treatment Plant Expansion Strengthening Jubail’s Urban & Industrial Ecosystem
The expansion of the waste water treatment plant in Jubail marks a major milestone in municipal sanitation under Saudi Arabia’s industrial development vision. Executed for the Power and Water Utility Company for Jubail and Yanbu (MARAFIQ), this project supports growing municipal wastewater loads from Jubail town and its industrial city while meeting stringent Royal Commission Environmental Regulations.
State-of-the-Art Municipal Wastewater Treatment Plant for Saudi Arabia
WABAG, as the General Contractor, delivered a world-class municipal wastewater treatment plant expansion through a comprehensive EPC scope covering design, engineering, and construction. The upgraded facility increases capacity to 120 MLD in Phase 1, with planned scalability up to 200 MLD, ensuring the waste water treatment plant meets future urban and industrial demands.
Waste Water Treatment Plant Delivering High-Quality Treated Effluent for Reuse
The plant employs advanced activated sludge treatment, carbon and nitrogen removal, filtration, and tertiary disinfection. This process ensures that the municipal wastewater treatment plant consistently produces high-quality treated effluent suitable for irrigation and landscaping, contributing to water conservation in one of Saudi Arabia’s most water-stressed regions.
A Future-Ready Sewage Treatment Plant Supporting Saudi Vision 2030
Built with a focus on modernization, sustainability, and operational automation, the upgraded sewage treatment plant integrates sludge treatment, odour management systems, TSE handling, and a SCADA-enabled control network. This enhances reliability and positions the project among leading wastewater treatment companies delivering large-scale, eco-efficient infrastructure.
EPC Expansion Scope for the Jubail Waste Water Treatment Plant
The EPC scope included expanding the plant’s hydraulic and biological capacity, constructing new treatment modules, upgrading sludge handling units, installing odour control systems, and integrating modern automation for streamlined plant performance. This ensures the waste water treatment plant supports both municipal and industrial wastewater flows.
Treatment Process Advancements Ensuring Compliance & Reuse Quality
The plant features an enhanced activated sludge process optimized for carbon and nitrogen removal. Additional systems include tertiary filtration, high-efficiency disinfection, and advanced sludge treatment — all critical for meeting Saudi Arabia’s regulatory requirements for irrigational reuse.
Municipal Wastewater Treatment Plant Designed for Long-Term Sustainability
By integrating low-energy aeration, modern filtration units, and robust SCADA automation, the municipal wastewater treatment plant ensures long-term operational stability. These enhancements reduce power consumption, improve effluent consistency, and support Jubail’s long-term water reuse strategy.
Contribution to Environmental Protection in Saudi Arabia
The waste water treatment plant expansion plays a major role in environmental conservation by producing treated effluent suitable for irrigation, reducing groundwater extraction, and minimizing ecological pressures in the industrial region.
A Benchmark Among Global Wastewater Treatment Companies
This project further reinforces WABAG’s reputation among international wastewater treatment companies. With advanced engineering and reliable execution, WABAG continues delivering world-class municipal wastewater treatment solutions aligned with the Kingdom’s sustainability goals.
