Renewing Water Supply
in Al-Muhajireen

The Al Muhajireen Water Pipeline project involved the renewal of urban water supply infrastructure through one of Amman's most densely populated residential and commercial neighbourhoods, following the Seil Amman corridor — a historic drainage channel that runs through the heart of the capital. CEC delivered the project for Miyahuna, Amman's water utility, replacing ageing distribution pipework with new mains designed to serve the area reliably for decades to come.

Unlike greenfield pipeline projects in open terrain, the Al Muhajireen works took place within a fully built-up urban environment — narrow streets lined with shops, apartment buildings, and a dense web of existing underground utilities including electricity cables, telecommunications ducts, sewer lines, and gas connections. The project required CEC's teams to plan every excavation with precise utility mapping, work in close coordination with residents and shop owners along the route, and maintain water supply continuity to connected properties throughout construction.

CEC's delivery of the Al Muhajireen Water Pipeline reflects our First Grade Water and Sewerage classification and our experience operating in Amman's complex urban core — a very different operating environment from the open desert and valley terrain of our regional pipeline projects, but one where CEC has built a strong track record of low-disruption urban utility works.

Engineering Challenges of Urban Pipeline Renewal

Renewing a water main through a live, densely built urban neighbourhood presented challenges distinct from greenfield pipeline construction:

• Live urban streets: Construction took place along active residential and commercial streets, requiring phased excavation, temporary reinstatement, and close coordination with the municipality to minimise disruption to daily life along the corridor.
• Buried utility conflicts: The Seil Amman corridor carries a dense network of existing buried services; trial pits and utility surveys were carried out ahead of excavation at every section to identify and avoid conflicts with electricity, telecoms, and sewer infrastructure.
• Traffic management on busy roads: Many sections of the alignment run along roads carrying significant daily traffic; CEC implemented traffic management plans including phased lane closures and signage to maintain safe passage for vehicles and pedestrians throughout the works.
• Minimal-disruption techniques near residences: Where open-cut excavation would have caused excessive disruption to building access or shop frontages, CEC employed trenchless and minimal-excavation methods to install or renew pipe sections beneath sensitive locations.

Scope of Work

CEC's scope on the Al Muhajireen Water Pipeline covered utility surveys and trial pitting along the full alignment; excavation and pipe-laying for new distribution mains, including trenchless techniques at sensitive crossings; connection of service laterals to existing buildings with minimal interruption to individual supplies; reinstatement of road surfaces, pavements, and street furniture to match existing conditions; and pressure testing, flushing, and disinfection of completed sections before handover to Miyahuna for commissioning into the live network.

Quality & Safety in Urban Construction

Working within an occupied urban neighbourhood placed a premium on public safety and communication. CEC maintained clearly signed and barriered work zones at every excavation, coordinated planned supply interruptions with affected residents in advance, and carried out daily site walks to confirm pedestrian routes remained safe and accessible. All pipe materials and jointing methods were tested and certified before backfill, and the completed network was disinfected and tested in line with Miyahuna's commissioning standards prior to being brought into service.
