What Does Televise Mean?
The term “televise” in the context of sewer maintenance refers to the process of using a closed-circuit television (CCTV) system to visually inspect the interior of sewer pipes. This method allows inspectors to identify potential problems and assess the overall condition of the sewer system without the need for extensive excavation. Closed circuit television video sewer inspection is a proactive approach to preventative maintenance that minimizes disruption of sewer service.
Preventative maintenance consists of two primary components: cleaning sewers and televising (video inspecting) them. This two-pronged approach helps identify damaged pipes that require repair or replacement.
Specialized equipment is used to inspect and clean the sewer system. This typically includes a remote-controlled unit with a mounted camera. Various types of cameras are employed, including mainline cameras with pan and tilt capabilities and advanced Panoramo 360 mainline cameras with Structure Inspection (SI) Scan functionality.
Traditional pan and tilt cameras provide a limited view of the sewer, capturing only what the camera is directly pointed at. However, the operator can manually adjust the camera’s direction to broaden the inspection. More advanced systems, like the Panoramo 360, capture a complete 360-degree view of the sewer, providing a comprehensive visual record of its condition. The SI Camera records the conditions of access points like manholes.
A strategic approach to sewer televising ensures regular inspection and maintenance. A common practice is to televise a certain percentage of the total sewer pipes each year, ensuring that every sewer main is inspected within a specific timeframe, often every ten years.
In addition to routine inspections, sewer televising is also conducted based on specific needs. These may include special requests triggered by cleaning crews identifying potential issues, inspections following water main breaks to assess potential damage to nearby sewer structures, and inspections before and after construction projects to verify the condition and proper installation of pipes and manholes. Occasionally, sewer televising services are contracted out to other city agencies or utility districts.
Televising sewers allows inspectors to identify a variety of issues, ranging from broken or cracked pipes to root obstructions. This information is crucial for prioritizing repairs and ensuring the long-term health of the sewer system.
While municipalities are responsible for maintaining the main sewer lines, property owners are typically responsible for the lateral lines connecting their properties to the main sewer. Homeowners concerned about the condition of their lateral lines can hire private sewer lateral cleaning services that offer televising capabilities.
Ultimately, understanding what “televise” means in the context of sewer maintenance highlights the importance of this technology in ensuring the efficient and reliable functioning of essential infrastructure.
