Centralized Sewage Treatment Plant BOO — Jazan Economic City
A centralized build-own-operate sewage treatment plant at Jazan Economic City, treating tanker-delivered domestic wastewater from contractor camps — 5,000 m³/day, fully automated with 24/7 monitoring.
A centralized domestic wastewater plant receiving tanker-truck inputs from Aramco contractor camps, treating 5,000 m³/day via an activated-sludge process with full sludge management. Fully automated by PLC with 24/7 online monitoring and remote alarms.
The plant treats 5,000 m³/day using an activated-sludge biological process with full sludge management — screening, equalization, biological reactor, clarifier, chlorination, storage tanks, and sludge drying beds — under complete PLC auto-control with remote alarm management.
A growing economic-city development needed a centralized plant to receive and treat tanker-delivered domestic wastewater from multiple contractor camps, reliably and with minimal on-site staffing.
- Multiple contractor camps, tanker-fed
- Centralized capacity — 5,000 m³/day
- Minimal staffing — high automation
A treatment train sequenced to the contaminants.
Screening and equalization buffer the tanker inflow; an activated-sludge biological reactor with clarifier reduces organics and separates solids; chlorination disinfects; and sludge drying beds dewater biosolids — all under complete PLC auto-control with 24/7 online monitoring and remote alarms.
