Al Samra Wastewater Conveyor Line — Electro-Mechanical Works Constructed by CEC in Zarqa

Al Samra Wastewater
Conveyor Line

A large-diameter wastewater conveyance pipeline feeding the As-Samra Wastewater Treatment Plant — Jordan's largest, serving Greater Amman and Zarqa. CEC delivered the electro-mechanical works: pumping stations, valve chambers, and the conveyance pipeline itself.

Conveying Wastewater
to Jordan's Largest Plant

The Al Samra Wastewater Conveyor Line is a major conveyance pipeline that feeds raw wastewater from Greater Amman and Zarqa into the As-Samra Wastewater Treatment Plant — by far the largest wastewater treatment facility in Jordan and a cornerstone of the country's water reuse strategy, with treated effluent released into the King Talal Reservoir for downstream agricultural irrigation. CEC was engaged by the Water Authority of Jordan, under the Ministry of Water and Irrigation, to deliver the electro-mechanical works package for this conveyance system.

The project routes wastewater flows through an industrial corridor in Zarqa, one of Jordan's most heavily industrialised governorates, where the pipeline alignment runs alongside factories, transport links, and existing utility networks. CEC's scope centred on the electro-mechanical components that keep the system operating reliably around the clock: intermediate pumping stations to lift flows along the alignment, valve chambers for isolation and flow control, and the installation of the conveyance pipe sections themselves with all associated mechanical fittings.

Because the As-Samra plant serves several million residents of Amman and Zarqa, any interruption to the conveyor line has immediate public health and environmental consequences. CEC's delivery — drawing on our First Grade Water and Sewerage classification — was planned and executed to keep the existing network operational throughout construction, with new sections tied in and commissioned under controlled, continuous-flow conditions.

Engineering Challenges of Large-Scale Conveyance

Delivering electro-mechanical works on a live wastewater conveyance system serving a national treatment plant presented several specific challenges:

  • Continuous-flow commissioning: New pipe sections, pumps, and valve chambers had to be tied into the live conveyance system without interrupting the flow of wastewater to the As-Samra plant, requiring carefully sequenced shutdowns and bypass arrangements.
  • Corrosion- and odor-resistant materials: Raw wastewater generates hydrogen sulphide and other corrosive gases; pipework, chamber linings, valves, and pump components were specified in corrosion-resistant materials with odor-control measures at chamber access points.
  • Industrial-corridor routing: The alignment through Zarqa's industrial zones required coordination with multiple landowners and utility operators, careful trenching around buried services, and traffic management on roads carrying heavy industrial vehicle flows.
  • Pumping station reliability: Intermediate pumping stations were equipped with duty/standby pump configurations, electrical control systems, and backup power provisions to ensure continuous operation given the critical nature of the conveyance line.

Scope of Work

CEC's electro-mechanical scope on the Al Samra Wastewater Conveyor Line encompassed installation of large-diameter conveyance pipe sections and fittings; construction and equipping of intermediate pumping stations including pump installation, electrical panels, and control systems; construction of valve chambers for isolation, air release, and flow monitoring; pipework jointing, pressure testing, and disinfection prior to commissioning; and tie-in works connecting new sections to the existing network under live-flow conditions, all coordinated with the Water Authority of Jordan's operations teams.

Quality & Safety on Wastewater Infrastructure

Wastewater conveyance works carry distinct health, safety, and environmental risks — from confined-space entry in chambers to the handling of pressurised pipework carrying raw sewage. CEC implemented a dedicated health and safety regime for this project, including confined-space entry procedures, gas monitoring at chamber locations, and rigorous pressure-testing protocols for all new pipe sections before commissioning. Quality assurance included material certification for corrosion-resistant components and full as-built documentation handed over to the Water Authority of Jordan upon completion.
