About Pipeline Services

Coblaco expanded its capabilities in the water treatment and water transmission industry upon acquiring American Pipeline Services (APS) in 2006. APS was recognized as an industry leader in pipeline repair and maintenance for decades leading up to the acquisition 15 years ago.

Coblaco has since refined operations and provided specialized solutions for hundreds of challenges in complex corrosive conditions and working environments.  Our extensive experience and expertise make us the ‘go-to solution’ for corrosion protection in water transmission pipelines, vaults, lift stations, balancing reservoirs and plant piping, and dam outlets and raceways.

Specialized services include:

  • Cement Mortar Lining (CML) joint repair & grouting

  • Interior/Exterior Pipeline lining & coating

  • certified lead & heavy metal abatement

  • Cathodic joint bonding

  • Confined Space - training & extraction

Texoma 72” Pipeline Improvement

The Texoma 72” Pipeline Improvement project was something new for American Pipeline Services. To retrofit this concrete-mortar lined pipe with cathodic protection, the steel needed to be exposed at each joint so that copper wires could be welded from one pipe to the next.  An absolute minimum of 900 joints needed to be fully completed in two weeks.

The East Cherry Creek Valley Sanitation District contracted Coblaco Services to recoat the interior and exterior of an aerial run of 30-inch sewer pipe. There were many variables with the project including: 

  • small diameter of the pipe

  • a flowing creek beneath the pipe 

  • thickness of the existing coating

  • the need to maintain sewer service for over 50,000 residents in this area via pipe bypass

Timing to complete this project was critical, due to the expense of the bypass.  Coblaco’s crews had to work long days and through the weekend in the punishing June sun so that the sewer pipe could be returned to service as soon as possible. A specified coating scope of work was done by Coblaco’s skilled technicians in spite of the environmental conditions, both internal and external. The quality inspection on this project was a critical path for delivery back to the customer, and was done so with diligence beyond the required scope specification.
