Flow Monitors
In February of 2001 the System Wide Modeling Project began collecting data from 145 flow monitors throughout the Mill Creek Watershed.
These meters are recording depth and velocity of sewage flow
in pipes ranging in size from 10" to 20'. The data will provide input
to the Model to calibrate system response to various storm events. After
extensive inspection and evaluation, the best possible sites were selected
for these installations. Flow conditions and the physical configurations
of the manholes were taken into consideration during the selection process.
Many factors affect a meter's performance. Meter data is continually
analyzed through scatter graphs and hydrographs to detect and remedy
any problems that may arise during the monitoring period.
These meters will be collecting data through June of 2001.
This time frame was selected to capture a wide range of storms that affect
MSD's sewer systems. In June of 2001 all but 60 flow monitors were removed
for use in the Little Miami and Great Miami watersheds in February 2002.
The 60 "permanent" monitors will continue to collect data in the Mill
Creek Watershed to update the Model indefinitely.
MSD currently maintains 148 flow monitor sites in support of the System Wide Model.
