, Description:BACKGROUND
[0001] Embodiments of a present disclosure relates to a monitoring system of underground structures and more particularly to a system and a method for monitoring and analysis of a sewerage.
[0002] Municipalities have a sanitary sewer system to collect and transport waste matter or sewage from one or more drains, disposals and other sources within a community to a sewage treatment plant. Ideally, the waste matter or the sewage is transported through the sanitary sewer system without any spillage or leakage. An access to the sewer system from ground’s surface is provided through a manhole, which further extends down to sewer pipes. The manhole is essential for an ongoing inspection, maintenance, and renovation of the sewer system. The manhole is protected by a manhole cover to prevent an accidental or an unauthorised access to the manhole. The inspection of the manhole is required for obtaining valuable information about damage or repair of the sewer system for maintenance. Various systems are available which are used for monitoring condition of the sewerage through the manhole in order to have the sanitary sewer system in the community.
[0003] Conventionally, the system for monitoring the sewerage includes locating the manhole by using a global positioning system (GPS) and detecting condition of the sewerage such as shape and size of the manhole, damage within or outside the manhole, or condition of lateral pipe connections within the manhole. However, the system is incapable of predicting a real-time status of the sewerage by identifying one or more materials and quantity of the one or more materials present within the sewerage. Also, such system is inefficient in detecting any tampering of the manhole cover by an access of the user. Moreover, such system requires manual intervention for one or more maintenance services of the sewerage.
[0004] Hence, there is a need for an improved system and a method for monitoring and analysis of the sewerage to address the aforementioned issues.
