Holding tanks need to be pumped depending on the water usage of a given residence and the size of the tank. Most are equipped with alarms indicating when the holding tank is full. Failure to pump a holding tank will lead to waste water backing up into the house or surfacing on the ground. Many holding tanks need to be pumped every 6-8 weeks, but seasonal residences may only need to be pumped once or twice a year.
Septic tanks will need to be pumped depending on the size of the tank and the number of occupants. For many, this will mean pumping a septic tank once every 2-4 years. If you have more than four people in your home or if you use a garbage disposal frequently, your tank should be pumped every year to 2 years. Minnesota Code 7080.2450 requires all septic tank owners to have a professional assess their system no less than every three years.
If your holding tank or septic system is experiencing infiltration or if you have more than six people living in your home, you may need to pump your tank more frequently. Minnesota code also requires a tank to be pumped if the solids content is more than 1/3 of the total tank volume.
Most newer systems are equipped the 24” manhole covers. It is important to pump the tank through this opening so the pumper can properly remove all of the solids and inspect the condition of the tank and baffles. Pumping through the maintenance hole opening of at least 20 inches in diameter is also a Minnesota code requirement (MN code 7080.1970).
