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 Ferroscope Pipe Bracelet Probe.

Ferroscope Pipe Inspection Technology

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.


• Scan at up to 12 feet/minute
• Horizontal and vertical pipes.
• Insulated plant piping
• Bare pipe in excavations
• 10” wide scans cover the whole pipe in a few quadrant scans

Pipe Bracelet Pipe Inspections

The PICA Pipe Bracelet Probe (BP) technology quickly and easily adapts to any size of ductile-iron, cast-iron or steel pipe, (starting at 6” diameter). The BP contains 16 high resolution sensors that cover a 10” wide scan path along the outside of the pipe.

The BP uses a low frequency EM (electro-magnetic) field that penetrates through the pipe wall. Variations in the thickness of the pipe result in changes to the field which is detected by the sensors .

These field variations are measured by a Ferroscope Instrument and are recorded and displayed by a lap top computer. The data is displayed immediately and available for instant analysis.

Rapid Results in Near Real-Time

Scanning up to 12FT/minute, we are able to take screen snap-shots which can be saved of the 3D color-maps, strip charts and voltage planes which are used to display and size the degree of pipe damage. Trends in wall thickness reductions can be easily seen and understood. Individual pits, graphitization and erosion are all immediately visible.

RECON+ Pre-Screening Inspection Tool Can Also Help Us Pinpoint Leaks in Your System

  • Hydrophone (leak detection)
  • Pressure
  • Magnetometer
  • XYZ (accelerometer and IMU)
  • Temperature

The hydrophone identifies and quantifies a leak’s signature (amplitude and frequency) and localizes it by combining all sensor data.

The pressure log senses changes in ID, debris and other bore restrictions and elevation changes.

The Magnetometer senses the start and end of different pipe types and thickness, magnetic repair clamps on plastic or AC pipe, metallic features such as tees, valves, and elbows. The best data collected with this pipe inspection tool is in 10” and smaller ID. With this in some cases we are also able to detect anomaly and joints.

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.
