Hannibal Board of Public Works says they will start flushing their water distribution system starting Tuesday as part of their regular maintenance program.
The project is expected to take about 30 days. The system flush will be performed in conjunction with a temporary use of free chlorine and fire hydrant testing. The system flush is intended to remove sediment from the pipes and distribute free chlorine throughout the entire water piping system. These items are standard practice. During this time period, ammonia will not be utilized as part of the drinking water disinfection process. Instead only free chlorine will be used.
Fire hydrant testing will be completed in conjunction with the system flush to obtain operational information for each fire hydrant.
