2265 Devin Lane
Orono, Hennepin County
To whom it may concern,
I was contacted by Mark Hanson to check if the existing septic system at the property of
2265 Devin Lane in the City of Orono is an imminent threat to public health. There is no sign of
septic effluent surfacing. Therefore, it is not an imminent threat to public health at this time.
The pump to the existing mound system is unplugged on 3/08/2026. The system is now a
holding tank system. This is a compliant septic system. There is an alarm in the third 1000-
gallon tank that will trigger a warning light and a buzzer in the house when the tank fills up with
approximately 300-gallons. That means you have approximately 700-gallons time for the owner
to call the pumper to come out and empty the tanks.
There is a design to fix the existing septic system. Once it is repaired it will be a
compliant mound septic system.
If you have any questions please call.
Sincerely
Joseph J. Olson
