Pipeline Condition Assessment by Digital CCTV and Video Inspection

Depending on the client's specifications and project requirements, DownStream Services, Inc. has the capability and technology to adapt to both internal and external factors which may influence an assessment. The physical characteristics of a pipe, as well as the project's environment and community impact, dictate the type and configuration of the camera. With a range of inspection equipment, DownStream Services, Inc. has the resources and qualifications to accurately inspect and assess sewer and stormwater collections systems.

CCTV Inspection for Sewer & Pipe Rehabilitation Capturing Real-Time Client Review Video:

DownStream Services, Inc.'s inspection systems are capable of articulating in adverse pipe conditions ranging from 3- to 200-inches in diameter. DownStream Services, Inc.'s standard method of inspection utilizes the Omni Eye Zoom Camera, manufactured by RS Technical Services. Designed to be mounted on a variety of transporters, the Omni camera conducts "circumference" observations of a pipe's interior up to 2,000-linear feet in a single run. For special applications and lateral inspections, DownStream Services, Inc. utilizes technology developed by ARIES Industries. With the ability to inspect 6-inch or greater, the ARIES lateral launcher and the RT-2000 crawler are vital to locating and identifying illicit connections, defects obstructing flow, and/or sources of Inflow & Infiltration.

DownStream Services, Inc.'s certified technicians remotely operate the CCTV cameras in specially designed, climate controlled studios located within each CCTV truck. Utilizing WinCan America's software as its operating platform, DownStream Services, Inc. has the technology to capture real-time audio documentation, digital imagery and video for the clients' immediate review. This service has proven to be crucial in pipe rehabilitation and emergency repair services.

Typically used in 6-inch or less pipeline inspections, including cleanouts and laterals, DownStream Services, Inc. also employs the VeriSight™ push camera systems from Envirosight LLC. With the ability to quickly capture detailed color inspection footage, this intuitive system allows field crews to survey and document up to 200-feet efficiently and safely without conducting Confined Space Entries.

Long-Range Sewer & Pipeline Inspection System Using Digital Sonar Profiling with CCTV:

Incorporating new technologies to meet the changing demands of the industry, DownStream Services, Inc. has teamed with Inuktun Services, Ltd. to provide a comprehensive program for long range inspections. DownStream Services, Inc. has incorporated "state-of-the-art" CCTV, Sonar, Laser, and H2S technologies in its pipeline inspection services with the added capability of inspecting over 6,000-linear feet in a single run.

Using digital multi-frequency Sonar profiling, DownStream Services, Inc. can provide critical information on charged pipelines and appurtenances. This tested technology generates a cross sectional scan of a pipe's interior, capturing the total volume of sediment and debris in varying flow conditions. Especially important in large diameter pipelines, Sonar profiling can identify structural inconsistencies and existing volume capacities. Atmospheric testing of O2, LEL's, H2S, and CO levels can also be accomplished and documented during a Sonar inspection. Operating independently or in conjunction with CCTV, Sonar profiling has adding another dimension to condition assessment.

Prior to merging the raw data into a final Deliverable, DownStream Services, Inc.'s has developed QA/QC procedures to ensure the consistency and quality of the video, audio, and overlays for each inspection. CCTV and Sonar Deliverables are a compilation of organized data provided in a traditional hard copy format or electronically on a USB hard drive. DownStream Services, Inc.'s Systems Management department is able to collect, analyze, and share "turnkey" PACP and MACP certified reports, supported by Flexidata™ and WinCan America's survey software. DownStream Services, Inc. will prioritize the assessment and recommended action based on industry standards for rehabilitation.

Manhole Inspections - Digital Video Documentation of Physical Integrity & Sewer Condition:

A typical Manhole inspection is a "non-entry" operation. DownStream Services, Inc. incorporates the Envirosight's QUICKVIEW® patented technology to perform the assessment. Prior to opening a Manhole cover, atmospheric conditions are checked and documented using a portable gas meter. Once the atmosphere is proven safe, the extendable camera is inserted into the Manhole documenting the physical appearance of the chimney or riser. With every inspection, DownStream Services, Inc. will measure and verify the Manhole rim to invert distance against provided documentation. Based on NASSCO's MACP standards, DownStream Services, Inc.'s technicians will note the presence of corrosion, root intrusions, debris and other structural defects. Scrape tests can also be performed to determine the Manhole's structural integrity.

The final full color report incorporates the condition of the cover, grade ring or frame, the cone, barrel, rungs, bench, and channel. Observations and comments are noted and accompanied with captured digital photographs and video. As part of the assessment, DownStream Services, Inc. can also recommend repairs associated with found observations.
