ALRAKA Compound, Dammam Governorate, Saudi Arabia MBBR STP 6000m3/day

Project Overview

This project encompasses the comprehensive civil and electromechanical execution required to install and commission a state-of-the-art 6000m3/day Moving Bed Biofilm Reactor (MBBR) Sewage Treatment Plant (STP) at the ALRAKA Compound in Dammam. Spearheaded by the Saudi Public Pension Agency in collaboration with Veolia, the initiative aims to upgrade the compound's wastewater management infrastructure to ensure high-efficiency, sustainable, and environmentally compliant water treatment.

Scope of Work

The project requires seamless coordination between structural, electrical, and mechanical disciplines to successfully integrate the packaged MBBR units into the compound's existing infrastructure.

Civil Works

Site Preparation & Earthworks: Excavation, grading, and backfilling for the plant foundation and underground utilities.
Structural Foundations: Casting reinforced concrete foundations, slabs, and equipment pads tailored to the weight and vibration specifications of the packaged MBBR units.
Containment & Access: Construction of retaining walls, access roads, walkways, and protective enclosures to ensure secure and safe operation by facility management.

Electromechanical (MEP) Works

Packaged Plant Installation: Hoisting, positioning, and secure mechanical anchoring of the modular MBBR biological treatment tanks and associated filtration units.
Piping & Hydraulics: Fabrication and installation of all interconnecting piping (inlet, effluent, sludge removal, and aeration networks), including valves, fittings, and flow meters.
Electrical Infrastructure: Installation of Main Distribution Boards (MDBs), Motor Control Centers (MCCs), and comprehensive power cabling to drive pumps, blowers, and mixers.
Instrumentation & Control: Integration of sensors (pH, dissolved oxygen, level transmitters) and PLC/SCADA systems to enable automated monitoring and optimal biological treatment cycles.
Testing & Commissioning: Rigorous hydro-testing, loop checking, and functional testing to validate system performance before final handover to Veolia’s operational team.

Technological Impact

By utilizing MBBR technology, the ALRAKA Compound benefits from a highly compact, robust, and scalable wastewater solution. The system utilizes specially designed polyethylene biofilm carriers to maximize the surface area for biological growth, allowing the plant to handle fluctuating domestic waste loads efficiently. The resulting high-quality effluent meets stringent local environmental regulations, enabling safe discharge or potential reuse for landscaping irrigation within the compound.
