Manhole Condition Assessment

Manhole condition assessment

MME field inspection personnel are trained and certified to account for the following:

  1. General features and information such as manhole ID, Location, size and condition of cover, ring, frame, material, and pipe connections
  2. Structural condition of steps, cone, riser, bench, and channel
  3. Hydraulics - inflow indicators, evidence of surcharge, clarity of flow, flow comparisons with adjacent manholes, and depth of flow.

The information obtained from the completed manhole condition assessment forms prepared in the field are reviewed for consistency and any missing or ambiguous information is revisited and updated based on field clarification.
