“…The Sewer Scanner and Evaluation Technology (SSET) developed by TOA Grout, CORE Corp., and the Tokyo Metropolitan Government's Sewer Service (TGS) Company utilizes optical scanner and gyroscope technology, in addition to standard CCTV technology [85,86]. Survey speed for the SSET is reported as 60 m/hour.…”

pipe networks assure the transportation of primary commodities such as water, oil, and natural gas. The quantitative and early detection of defects in pipes is critical in order to avoid severe consequences. As a result of high-profile accidents and economic downturn, research and development in the area of pipeline inspection has focused mainly on gas and oil pipelines. Due to the low cost of water, the development of nondestructive inspection (NDI) and structural health monitoring (SHM) technologies for fresh water mains and sewers has received the least attention. Moreover, the technical challenges associated with the practical deployment of monitoring system demand synergistic interaction across several disciplines, which may limit the transition from laboratory to real structures. This paper presents an overview of the most used NDI/SHM technologies for freshwater pipes and sewers. The challenges that said infrastructures pose with respect to oil and natural gas pipeline networks will be discussed. Finally, the methodologies that can be translated into SHM approaches are highlighted.

“…Direct human inspection, which is possible, at least in principle, for above-ground exposed infrastructure such as tunnels and road surfaces, is simply not possible for sewage pipes because of their relatively small size and buried state. Thus there has long been interest [15] in automated approaches, normally a small remotely-controlled vehicle with a camera. A sewage pipe would normally be classified [16] into anticipated structures,  Undamaged pipe  Pipe joints (connections between pipe segments)  Pipe laterals (connections to other pipes) and some number of unanticipated problem classes:…”

“…Because the most common approach is to have a forward-looking camera looking down the pipe, the CCTV method suffers from drawbacks of geometric distortion, a significant drawback in automated analysis. Sewer scanner and evaluation technology (SSET) [15] [20] is similar to the SSET approach, in that a laser scans the pipe surface circularly, with an offset camera observing the laser spot and allowing the three-dimensional surface geometry of the pipe to be constructed via triangulation. There are a few further strategies, albeit less common, for sewer pipe inspection.…”

This review paper presents the current state of practice of assessing the visual condition of vertical and horizontal civil infrastructure; in particular of reinforced concrete bridges, precast concrete tunnels, underground concrete pipes, and asphalt pavements. Since the rate of creation and deployment of computer vision methods for civil engineering applications has been exponentially increasing, the main part of the paper presents a comprehensive synthesis of the state of the art in computer vision based defect detection and condition assessment related to concrete and asphalt civil infrastructure. Finally, the current achievements and limitations of existing methods as well as open research challenges are outlined to assist both the civil engineering and the computer science research community in setting an agenda for future research. Keywords:Computer Vision, Infrastructure, Condition assessment, Defect detection, Infrastructure monitoring Research Highlights: Visual inspection of civil infrastructure is essential for condition assessment.  We focus on concrete bridges, tunnels, underground pipes, and asphalt pavements.  Accordingly, we review the latest computer vision based defect detection methods.  Using computer vision most relevant types of defects can be automatically detected.  Automatic defect properties retrieval and assessment has not been achieved yet . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 ...

“…Rehabilitation of sewers reduces infiltration of water into the system and thereby relieves sewage treatment plant, increases capacity of the sewer system [2]. Damaged sewer lines, especially the oldest combined sewers typically located in city centre with high historical or strategic meaning, require rehabilitation works.…”

Abstract:The sewerage network in Poland, built in the early 20th century, has been losing its original water-tightness and flow capacity. To bring these characteristics back, rehabilitation works are performed. The initial capacity of sewers can be restored without affecting the urban environment thanks to the trenchless technology. The sewer subjected to rehabilitation receives a new internal leakproof layer capable of preventing groundwater infiltration as well as sewage leaks, which can contaminate the environment. This paper intends to compare the trenchless technology with traditional open cut trench excavation. In the study, two variants of trenchless rehabilitation were considered: one performed with the help of GRP panels and the other using cured-in-place pipe (CIPP) lining. Flow velocities and flow rates in the sewers before and after rehabilitation were compared. Also, selected economic and environmental aspects of sewer rehabilitation methods were examined.
