Operation and Maintenance of BWRO in Um Aljerem City – NWC

Project Overview

This critical municipal utility project involves the comprehensive Operation and Maintenance (O&M) of the primary Reverse Osmosis (RO) Water Treatment Plant serving Um Aljerem City. Executed on behalf of the National Water Company (NWC), the project is dedicated to ensuring a continuous, reliable, and safe supply of potable water to the city’s residents. By efficiently managing the extraction and high-level purification of local groundwater or brackish sources, the initiative plays a pivotal role in sustaining public health, supporting urban development, and reinforcing regional water security.

Scope of Work

  • Continuous Plant Operations: 24/7 management of the complete water purification cycle, including raw water extraction, pre-treatment filtration, high-pressure RO separation, and final post-treatment (remineralization and disinfection).

  • Preventive & Corrective Maintenance: Executing systematic maintenance schedules for all electromechanical assets, such as high-pressure feed pumps, booster pumps, chemical dosing skids, and electrical control panels, to eliminate unplanned downtime.

  • Membrane Management & Optimization: Conducting routine chemical Clean-In-Place (CIP) protocols, monitoring Trans-Membrane Pressure (TMP), and optimizing recovery rates to maximize the operational lifespan and efficiency of the RO membranes.

  • Water Quality Assurance: Performing rigorous daily laboratory testing and continuous inline sensor monitoring (for pH, conductivity, and chlorine levels) to ensure the product water strictly adheres to NWC’s stringent drinking water quality standards.

  • HSE & Reject Management: Enforcing strict Health, Safety, and Environment (HSE) protocols for chemical handling and ensuring the safe, environmentally compliant disposal or management of the highly saline reject water (brine).

Technological Impact

By utilizing advanced Reverse Osmosis (RO) technology, the Um Aljerem plant is capable of treating highly brackish groundwater, transforming it into exceptionally pure potable water that meets world-class health standards. The integration of a centralized SCADA (Supervisory Control and Data Acquisition) system allows operators to remotely monitor hydraulic pressures, flow rates, and water quality parameters in real-time. This high level of automation not only reduces the margin for human error but also optimizes the energy consumption of the high-pressure pumps, ensuring the plant operates with a highly efficient energy-to-water production ratio.
