sewer inspection
Corrosion Sewer Inspection
Responder’s array of sensors can be used to determine what locations within a pipe are suffering from corrosion and how much corrosion there is. Below the flow-line, sonar sewer profiles the pipe shape for comparison with as-built drawings. Above the flow-line the laser scanner does the same, while the gas sensor logs H2S levels.
Cleaning pre-bid sediment and FOG (fats, oils, and greases) inspection
Responder provides accurate pipe sediment volume and sediment location within the submerged portions of a pipe using its unique trenchless technology. The on board Turret Scan allows for debris modeling below the flow and is a cost effective way to eliminate by-passing and dewatering to inspect submerged sections of the pipe. This information can be used to prioritize areas for sewer cleaning and to determine the extent of sewer cleaning operations required.
Post Sewer Cleaning Scope Verification
Without a baseline, it is difficult to truly judge the effectiveness of a sewer cleaning deployment. The on board Turret Scan allows for debris modeling below the flow and is a cost effective way to eliminate by-passing and dewatering to inspect submerged sections of the pipe. Following a cleaning, Responder can reinspect the pipe and determine how much sediment was displaced.
Emergency Response - Blockage Modeling
In an emergency response, Responder can be deployed to identify, locate, and sometimes dislodge a pipe blockage. Because this can be done in a submerged or partially submerged environment, it is not necessary to bypass pipe for an emergency sewer inspection.
PACP/WRC Defect Identification
Information from Responder’s many sensors can be used to accompany a PTZ camera for PACP/WRC reporting. The sensors are capable of identifying defects that often times are not visible to a camera operator. All defects identified can be classified in a format so as to meet PACP or WRC reporting standards.
Pipe meander and incline
Responder’s positioning sensors and payout information allow the robot’s position during the sewer inspection to be known at all times with a high degree of accuracy. This information can be used to locate connecting pipes or lost access points, as well as to create a meander and incline report.
Flow Characteristics between manholes
With an on board flow sensor, the Responder is able to determine flow characteristics throughout its deployment during the sewer inspection, rather than only at manholes. This information can be used to determine flow velocity and volume in any area as well as possible infiltration or exfiltration.
Baseline Assessment
Any Responder deployment can be used as a baseline for comparison with later deployments. The baseline sewer inspection information is significant in that it allows analysis and visualization of changes within a pipe over time. It also provides three dimensional data for sewer asset management and inventory purposes.
Time Based Analysis
With a baseline or multiple baseline sewer assessment, time based analysis can be conducted. Changes within a pipe can be visualized and quantified relative to the previous analyses. The rate of change can be determined, in determining things such as how fast a pipe is deteriorating or sediment is building up, and in what areas, in order to identify possible failure points and aid in effective allocation of resources.
