Dodsal - 3000 CMD Sewage Treatment Plant
The Challenge
A leading hospitality client in Abu Dhabi required a reliable sewage treatment solution to handle large daily volumes of wastewater. The challenge was to design and build a system that could manage 3,000 m³/day (3 MLD) of sewage while ensuring treated effluent consistently meets local environmental and reuse standards. In addition to treatment efficiency, the project demanded a robust piping network, long-term durability, and seamless integration into the client’s operations.

GWT Solution
To meet the client’s requirement of treating 3,000 m³/day of sewage, Gulf Water Treatment designed and delivered a comprehensive system built around reliability, efficiency, and compliance. The solution began with a robust screening and pre-treatment stage, ensuring that solids and debris were effectively removed before entering the main treatment line. This not only prevented clogging but also protected critical downstream equipment, extending the operational life of the entire facility.
The heart of the plant lies in its advanced biological treatment process, engineered to reduce organic load and consistently deliver effluent that meets the region’s strict environmental and reuse standards. By combining proven biological systems with optimized process control, the plant ensures steady performance even under fluctuating loads.
To further polish the treated water, a multimedia filtration system was integrated, providing a final barrier that guarantees high-quality effluent suitable for reuse in landscaping and other non-potable applications. This step added an extra layer of confidence for the client, reinforcing long-term sustainability goals.
Supporting the treatment processes, a five-kilometer piping network made of high-density polyethylene (HDPE) was installed for sewage collection and treated water distribution. HDPE was selected for its strength, durability, and resistance to corrosion, ensuring the infrastructure can withstand the demands of continuous operation in challenging conditions.
Finally, the entire system was equipped with automation and real-time monitoring features. This allows operators to continuously track plant performance, optimize treatment efficiency, and respond quickly to any variations. The combination of advanced process design, durable infrastructure, and intelligent monitoring created a solution that not only addressed the immediate challenge but also positioned the client for long-term operational stability.
