Dale Monson
2730 Silverview Drive
Orono, Hennepin County
To whom it may concern,
I was contacted by Dale Monson to design new septic tanks for 2730 Silverview Drive.
The existing tanks leak below their design operating level and need to be abandoned and
replaced. They need to be replaced with a minimum of a 2250 -gallon combination septic tank or its
equivalent. The existing lift station needs to be replaced with a minimum of 1000 -gallon tank. The
existing system is designed for a three-bedroom house.
The TBM is the top of the basement door threshold. Elv-100.0 The elevation of the grade for the
proposed new tank is at 100.1 The top of the existing first tank is at Elv-98.4. The elevation of the grade
for the proposed new lift station is at Elv. -100.9 The top of the existing lift station is at Elv-97.6. All
tanks need to be insulated if there is less than two feet of cover over the top of the tanks.
The existing mound system meets the 2.0 -foot separation to the periodically saturated soils.
If the tanks are replaced the septic system will be compliant.
See drawing for the location of the new septic tank
If you have any questions please call.
Sincerely,
Joseph J. Olson
