Department Overview

Meet our Sewer Crew

The first sewers in Hannibal were constructed around the turn of the century and consisted of combined systems carrying both storm and sanitary waste. In 1968, a sewer bond was passed by the voters of Hannibal to separate the storm and sanitary waste by adding several thousand feet of new sewer lines and constructing lift stations to carry sewage to the Wastewater Treatment Plant. Presently, the Board of Public Works maintains approximately 140 miles of sewer mains.

Throughout the year, the sewer crew is busy maintaining and repairing city sewer lines.  This involves:

  • Manhole inspections
  • Manhole raising
  • Cleaning of sewer mains
  • Repairing broken pipes
  • Televising of sewer mains
  • Smoke Testing

Weather permitting, the crew is responsible for these tasks year-round.  However, during seasons of high rain, the crew is careful to inspect areas where water, other than wastewater, enters the sewer system.  This type of water, called Infiltration/Inflow (I/I), can reduce the capacity and capability of sewer systems and treatment facilities to transport and treat wastewater.
