• Delivered 8 new water meters, installed a Smart Point module, and took curb stop ties.

• Submitted Discharge Monitoring Report (DMR) for the diesel generation plant to the
Minnesota Pollution Control Agency.
• Submitted Tier II Annual Reports to the Department of Homeland Security for the diesel
generation plant and all the water treatment plants.
• In reviewing video taken of well 7 while the pipe, pump, and motor were removed for
maintenance, it was determined that the screen needed to be cleaned due to over 20
years of mineral buildup. The screen cleaning process involves a combination of a
carefully planned chemical treatment and physical removal of mineral deposits. The
cleaning process was completed March 1, and a new video was taken of the well that
shows that the screen looks almost new again. Before and after pictures are attached.
• Work has been completed replacing the programable logic controller (PLC) for well #9.
This will allow our Supervisory Control and Data Acquisition (SCADA) system to
communicate through fiberoptic instead of the current radio system that has had some
reoccurring communication issues at this site.

• The back-up dialer unit that calls out system alarms to staff in case the main SCADA
system dialer program fails to call out has been upgraded. This will help ensure that
system alarms are sent out so that staff are notified of, and are able to react to, any
issues that may be happening in the water system.
• Verizon wireless has completed their most recent equipment upgrade project at
Freeport Water Tower.
• The water operators have spent much of their time performing annual preventive
maintenance on the water treatment plants.
