Runoff water inflow into the sewer system
On Monday, February 21, 1994, Ken Lindsay called and informed me
that the sewer system in the Westwind area had experienced
extremely high flows over the weekend. Ken and I made a field
inspection the same day. We determined that runoff from the recent
snow melt had drained into the last manhole along CSAH 37 in the
parkside Second Addition project. See the attached map. This
manhole currently does not have its casting and rings in place,
since the watermain and right turn lane must still be installed in
this area. Once the casting and rings have been installed, the
manhole will be at least 1.5 feet higher and will not have any
more inflow problems.
As an interim solution, Ken and I decided to install a sewer ball
in the downstream side of this manhole to plug the sewer and
prevent inflow from entering the sewer system. I will take care of
this by Wednesday, February 23, 1994.
