What An Adequate Manhole Inspection Requires

Manholes, also known as catch basins, are an integral part of any modern drainage system. They provide access to the underground pipes for maintenance and repair, and act as a control point for the flow of stormwater. 

Without proper inspection and maintenance, manholes can pose a serious risk to both public safety and the environment. Check online resources to get more information about Manhole inspection camera.

While the frequency of manhole inspections will vary depending on the location and condition of the manhole, it is generally recommended that they be inspected at least once a year. More frequent inspections may be necessary if there is evidence of deterioration or if there have been recent changes to the surrounding area (e.g., construction activity).

Here are some key elements:

1. A visual inspection of the manhole covers and frames to check for signs of damage or deterioration.

2. An assessment of the surrounding area, including any potential sources of infiltration (e.g., cracks in the pavement or leaks in nearby pipes).

3. An evaluation of the condition of the manhole itself, including any structural damage or corrosion.

4. A determination of the level of water in the manhole. This may require lowering a camera into the manhole to take pictures.

5. Water quality testing.

6. Detection of any potential hazardous conditions, including chemical spills, methane gas leakages or other toxic emissions that may be present in the manholes (if such a situation is suspected).
