PIPELINE INSPECTION & ASSESSMENT
CPM has invested in a number of technologies and equipment for the inspection of both water and wastewater pipelines.
Over the past 10 years, CPM has completed pipeline assessment services on over 500 pipelines for clients throughout the United States. CPM staff is capable of self-performing inspection of all sized pipelines for water distribution and wastewater collection. The CPM team has service equipment for confined space entry, work within municipal right-of-way, as well as pipelines within treatment plants, pump stations, and reservoir sites.
For gravity wastewater pipelines, CPM can provide equipment and services with the InfoSense SL-RAT equipment to determine whether blockages are present in 12 inch and smaller gravity sewer pipelines. Our team is capable of completing up to 15,000 feet of SL-RAT inspection in a workday, which provides clients GIS layers with color coded results that ca be added to any ESRI asset management database.
CPM also offers Electroscan for gravity sewer inspections from 2 inch up to 60 inch with objective results for the assessment of non-ferrous pipelines or cured-in-place-pipe (CIPP). CPM can also provide manhole inspection services, as we have staff that are NASSCO PACP and MACP Certified.
CPM has also invested in technologies for the inspection and assessment of sewer forcemains.
The first step in this process that CPM employs is the inspection, maintenance, and assessment of the air release valves on the forcemain that also typically allows for wall thickness testing using the Ferrouscope Pipe Braclet Probe.
The next step would be to use free swimming acoustic equipment inside the pipe to identify the location and size of gas pockets so that the Pipe Bracelet Probe can measure the pipe wall thickness at those locations as well. If additional, and more finite data, information is desired to make a decision on the condition of the forecemain, CPM will utilize the PICA See Snake to obtain pipe wall defection and thickness information on the entire pipeline alignment.
For water distribution and transmission pipelines, CPM has a wide variety of technologies and service offerings.
For smaller diameter pipelines, CPM has three dedicated potable water CCTV robots and cameras that have 1,000 foot of tether on each reel. CPM has been providing potable water CCTV inspection services for over 7 years, and have inspected hundreds of miles of pipe using this equipment.
The Ferrouscope Pipe Bracelet Probe can be used on the exterior of smaller diameter water distribution pipes as well to determine the wall thickness of metallic pipes, such as ductile iron, cast iron, and steel cylinder pipes. CPM has also completed potable water CCTV on larger transmission lines as well, but also has extensive experience and capabilities performing manned visual and sounding inspections on pipes 30 inch and larger. While performing these inspections, CPM will also collect detailed information on the pipeline condition, alignment information, inline valve condition, and defect information.
CPM’s pipeline inspection and assessment approach provides clients, whether it is a municipality, consultant, or contractor, turnkey solutions for collecting and providing the condition assessment data needed for making decisions on the current condition and remaining useful life of water and wastewater pipelines.
CPM has the staff, equipment, and technologies in-house for completing inspections and providing condition assessment data critical in assessing the condition of aging water and wastewater infrastructure.
CPM’s turnkey approach to completing these condition assessment tasks results in an efficient and economical approach to pipeline inspection and condition assessment.
Clients of all sizes have been pleased with the comprehensive approach to pipeline inspection and assessment because of the wide variety of services and technologies that CPM brings to each project. The data collected when CPM performs a condition assessment project is always useful in the clients condition assessment decisions and future actions for those pipelines.
