5 / Parson Environmental Products high-density polyethylene manhole inserts
High-density polyethylene manhole inserts from Parson Environmental Products can help eliminate surface water inflow along with unwanted hydrogen sulfide odors and are easy to use and maintain. They include a vented PVC canister that stores 20 pounds of either activated or catalytic carbon. The result is a product that traps and stores all of the unpleasant hydrogen sulfide and methyl mercaptan odor molecules before they are released into the atmosphere. The only item that needs to be replaced periodically is the 20 pounds of carbon since it serves as the absorbent media that traps the odor molecules. One person can easily accomplish this. 800-356-9023;

Manhole Cameras

The SPiDER scanner from CUES can calculate its position in the manhole shaft by using its sensor data to measure its incremental motion instead of the payout cable. It weighs less than 30 pounds and can be hand-carried to easements or other previously difficult-to-access sites. This wireless portability is possible because the processing computer and battery supply are built into the scanner. It collects millions of 3D measurements during each manhole inspection, so the manhole can be measured to better than 5 mm accuracy. The point cloud can be used to evaluate the structural changes in a manhole before and after rehab. It also provides live-video stream and recorded MPG video, making it an ideal wireless tool for inflow and infiltration studies. 800-327-7791;

7 / Envirosight CleverScan
The CleverScan manhole scanner from Envirosight performs a comprehensive, fully automated assessment of manhole condition in two to three minutes. It captures visual and dimensional data, and it presents the user with a flat scan with detailed image data covering every inch of the manhole wall; a dense point cloud for 3D visualization of the manhole structure and easy CAD integration; and a virtual view inside the manhole, where an operator can pan, tilt and zoom to areas of interest. It sits over an open manhole. With the press of a button, the system’s probe descends into the manhole, capturing image data using five HD cameras and building a dimensional profile using an array of four lasers. An onboard rangefinder controls descent and determines when the scan is complete. Scan data is immediately transferred to a laptop running specialized software, where it can be viewed, annotated and shared. 866-936-8476;

8 / RapidView IBAK North America PANORAMO SI
The PANORAMO SI manhole inspection system from RapidView IBAK North America offers 100% coverage, inspection speeds of up to 14 inches per second, geometric measurements from any point inside the manhole, laser depth measurement, 225 feet of cable, and can be operated in manholes 10-inch-diameter and up. The software allows the user to view the manhole from any angle and at any position, creating a virtual-reality-style view of the manhole. This file can be viewed from any computer, anytime. The system also automatically generates a 3D model of the inside of the manhole that can be rotated, viewed, measured or output to a CAD file for further analysis. The system can be an addition to a PANORAMO mainline inspection system or is available in a stand-alone version. It allows a crew to inspect more than 50 manholes per workday. 800-656-4225;

Manhole Liners
