People contact the Sewer District with complaints about how deep our manhole is in a certain location but the fact is our manholes are STATIONARY- it is the Road that moves. ALASD works with the Street Department on some of these issues by installing risers if able, but If you notice a deep manhole or have concerns about one please contact your Street Department.
A manhole cover or maintenance hole cover is a removable plate forming the lid over the opening of a manhole, an opening large enough for a person to pass through that is used as an access point for an underground vault or pipe. It is designed to prevent anyone or anything from falling in, and to keep out unauthorized persons and material. (wikipedia)
