Network Rehabilitation Program – Mainland 7 (Abu Dhabi)
Project Description
This urban sewer network suffered from high infiltration during seasonal groundwater rise, combined with salinity contamination damaging concrete structures and affecting plant efficiency.
Client: TAQA Water Solutions
Project No.: O-15213
Location: Mohammed Bin Zayed (MBZ) City
Consultant: Dorsch
Challenge:
-
Infiltration mainly through pipeline joints spread over a large residential area
-
Traditional open-cut repairs would require road closure permits, diversions, and cause major disruption to residents
Solution & Result:
Through targeted CCTV inspections and precise gel grouting at leaking joints, all infiltration points were sealed without surface disturbance. Post-rehabilitation monitoring confirmed complete elimination of saline water ingress, restoring network integrity and extending service life.
