CTI Engineering Co., Ltd. announced on the 4th that it has developed a technology to detect various abnormalities in sewer pipes at an early stage. Investigate the water level and microorganisms in the sewer pipe to detect abnormalities such as flooding and corrosion of the sewer pipe. Abnormalities can be detected earlier than the conventional technology, and merits such as improvement of maintenance efficiency and cost reduction can be expected.
Abnormality is detected by real-time monitoring of water level and microbial survey. Water level monitoring can be performed simply by installing a transmission antenna without replacing the manhole lid. Observe the water level in the sewer pipe and check and share the water level status in real time. Abnormalities related to water level rise in sewer pipes such as unknown water and flooding can be detected at an early stage.
In the microbial survey, corrosion factors and locations are detected at an early stage by collecting and analyzing sewage. Using a next-generation sequencer (NGS) that reads DNA sequences, it has become possible to analyze a wide variety of bacterial levels. By identifying the causative bacteria that promote corrosion and performing quantitative analysis by location, areas that are prone to corrosion are detected.
According to CTI Engineering Co., Ltd., by applying the developed technology to a comprehensive private consignment project for sewerage pipeline facilities, more effective maintenance will be possible. It can also be used by local governments and private sewerage maintenance companies.
Important issues in the sewerage field include disseminating information on the danger of flood damage and efficient measures against aging facilities. However, early detection of flooded areas, factor investigation, and identification of facilities with a high risk of aging required labor and high consignment costs for staff.
