4. c) Letter -Pump Tank Access - raising and resealing
August 28th, 2020
Residents of the Bliss and Anderson Erickson Sewer systems,
Your septic system is a part of the Big Marine Sewer System which the City owns and
maintains. The system has infiltration and inflow (I&I) issues which is caused by water
running into the system through natural means such as rain and snow melt in the spring.
The I&I issues cause the system to run more often, use more electrical power, and reduce
capacity of the system. You, as the users, pay the fees to cover the extra costs. The City is
working toward minimizing the I&I issues of the system. Much of the infiltration is due
to old seals and access lids on pump tanks. It has been determined that raising your pump
tank access lid would benefit in relieving the system of some of the I&I issues.
City staff will remove the existing access lid and replace it with a steel casting and lid.
There will be a new seal applied as the casting is set on the old rings. The difference in
height change will be 4-6” from the current height of the access lid. City staff will add
soil, taper the soil away from the new access casting, rake, and seed the damaged area. It
is anticipated that no machinery will need to be driven onto properties. Work is planned
to begin the third week in September. Public works staff will notify you the week we will
be working in your area. No action is required from you.
Please contact me at (651) 433-5223 or a.hawkinson@ci.scandia.mn.us if you have any
questions.
