How often should a septic tank be pumped?

Most septic tanks should be pumped every three to five years depending on household size and water use.

Pumping removes accumulated sludge and solids that would otherwise reach the drain field, but it does not address soil restrictions in the drain field.

If you use our system, pumping requirements are very limited, as all organic content is efficiently digested. Non-organic contents may require pumping, and then bacterial cultures will need to be re-introduced.
