One of the primary water transmission pipelines for a
large Metro Atlanta water system failed catastrophically
after more than twenty years in service. The failure was
discovered when surface water was seen in the center
lanes of Interstate 85, a primary traffic corridor
outside of metro Atlanta. MME assembled a
multidisciplinary team to evaluate the water leak and
investigate the situation. MME’s ground penetrating
RADAR team successfully identify the water leak and its
path from the pipeline to the surface.

MME’s remote CCTV
inspection team identified the exact location of the
internal pipeline rupture. After initial inspection, a
team of metallurgical, civil, structural and welding
engineers performed a comprehensive failure analysis,
including the design of a long-term, trenchless repair.
MME identified poor quality control practices during
initial construction as the primary cause of failure,
specifically with respect to welding and backfill. MME
managed the reconstruction project, including
non-destructive inspection of the repair welds, and
successfully re-established water transmission without
disruption of service to the system as a whole. |
