In general when is the best time to have my tank pumped or serviced?

Oconto County's intention is to have all maintenance notices sent between late spring through early fall. Holding off on pumping until late fall increases the possibility of freezing your septic system if the tank is required to be pumped. See question regarding when tanks need to be pumped and the required servicing. All septic tanks need warmth to maintain a temperature above freezing through the winter months. Last winter's weather was conducive to freeze-ups since there was no snow cover for insulation during the cold temperatures. In order to avoid freeze-ups it is best to perform the maintenance in the summer months. If the tanks cannot be pumped until late fall or later provide additional insulation over the tank(s).
