Operation and Maintenance of Sewage Water Treatment Plant and Networks in Afif Governorate

Operation and Maintenance of Sewage Water Treatment Plant and Networks in Afif Governorate

Project Overview

This project entails the comprehensive Operation and Maintenance (O&M) of the main Sewage Treatment Plant (STP) and its extensive underground collection network in the Afif Governorate. Executed on behalf of the National Water Company (NWC), the project ensures the continuous, safe, and efficient processing of municipal wastewater. The initiative is critical to safeguarding public health, preventing groundwater contamination, and maintaining high sanitation standards throughout the governorate.

Scope of Work

  • STP Daily Operations: 24/7 management and monitoring of all wastewater treatment phases, including preliminary screening, biological treatment, clarification, and final disinfection.

  • Network & Lifting Stations Management: Routine inspection, cleaning, and unblocking of the sewage pipeline network and manholes, alongside the operation of lifting and pumping stations to ensure uninterrupted flow and prevent sewage backups.

  • Preventive & Corrective Maintenance: Executing systematic maintenance schedules for all electromechanical assets, including sewage pumps, aerators, mixers, scrapers, and control panels, to maximize equipment lifespan and minimize downtime.

  • Water Quality Control & Sludge Handling: Conducting rigorous daily laboratory analyses to ensure the treated effluent meets strict NWC and environmental guidelines. Managing the safe dewatering, transport, and disposal of biological sludge.

  • Emergency Response: Providing rapid-response teams to address network leaks, pipeline blockages, and electromechanical failures within the plant or across the city's infrastructure.

Technological Impact

By utilizing advanced SCADA systems and remote telemetry, the project team can continuously monitor flow rates and pump statuses across the Afif network in real-time, allowing for rapid detection of blockages or pressure drops. The integration of Geographic Information Systems (GIS) optimizes the mapping and maintenance routing for the underground pipelines. Furthermore, automated dissolved oxygen (DO) controls within the aeration tanks drastically optimize energy consumption, ensuring the plant operates with a highly efficient energy-to-treatment ratio while maintaining superior effluent quality.
