According to Minnesota Pollution Control Agency rules, septic tanks need to be pumped at least once every three years to remove excess accumulation of sludge, grease and scum.
You may receive a reminder postcard from Dakota County. Septic pumpers are required to submit monthly pump logs to Dakota County, and records are updated accordingly. If you received a reminder postcard and you have recently had your tank pumped, or if any information on the postcard (name, address, etc.) needs to be updated, please contact the Environmental Resources Department by phone at 952-891-7000 or email firstname.lastname@example.org.
Septic smart tips: Extend your system's life span
These tips will help keep your septic system working longer:
Use water-efficient appliances.
Spread out water use.
Avoid garbage disposal use; composting
is a better option.
Avoid flushing wipes or feminine hygiene products.
Install a lint filter for the washing machine.
Minimize use of harsh cleaners, bleach, detergents, disinfectants and soaps.
Do not dispose of medications, paints or chemicals through your septic system.
Avoid septic tank additives — only pumping removes sludge and scum.
