The wastewater- and sewage distribution network is a critical aspect for maintaining a socialandenvironmental well-being. However, in the latest time, many failures (such as leakages) haveoccurred due to poor conditions in the wastewater-infrastructure, causing several consequencessuch as damage to the environment or pose health hazards to the public. This study is dividedinto three parts. Part one compares five different sewage inspection technologies: Closed-CircuitTelevision (CCTV), Zoom Cameras, Digital Scanning, SONAR and Electro Scanning with thepurpose of identifying a new system that Stockholm Vatten & Avfall (SVOA) should considerimplementing. Part two goes through the inspection procedure that SVOA applies, andrecommendations are concluded as to how the process can be optimized. Part three coversessential aspects that should be taken into account before investing in a new technology. Theresearch methodology involves collecting data from literature, internal reports from SVOA, andconducting interviews with supervisors and field workers. The main finding is that SVOA shouldcontinue with the current approach that the utility is using because the current data found in thecurrent literature is too insufficient and not too strong which makes it not convincing to investinto a new technology. On the other hand, the collected data about the technologies can beconsidered whenever the approach is moving towards a proactive approach.
