The A’Seeb wastewater project is Muscat’s first wastewater management system. Covering 189 mi2 (490 km2) of established urban environment, the system was designed for more than municipal sanitation—it also supplements the region’s water resources by treating 100% of wastewater to the high-quality level required for beneficial reuse and distributes the recycled water.
Parsons was the engineering consultant responsible for front-end engineering design, project management, and construction supervision of six separate construction contracts. The wastewater management system includes numerous features:
Design measures for the project included flood protection for the riverine-like geography with wadis (dry rivers that flood during rain), a vacuum system for areas with a high water table, and enclosure of the Seeb wastewater treatment plant plus odor control solutions to meet the requirement of no odor at the facility’s boundary.
Our project management approach delivered uniform quality assurance and quality control among the six contractors executing the project. We helped the local and international contractors upgrade and implement quality plans and conducted audits to ensure full implementation of the quality systems throughout the project.
