How often should I pump a septic tank, and how much will it
cost?   Under normal conditions, you would pump a septic system
every 1-3 years... 1-2 people in the house=every 3 years 3-5
people in the house=every 2 years 6+ people=every year  It will
usually cost from $75 to $200 for to pump a septic tank (however
in some parts of the northwest it can run up to $300+). Now lets
say it costs you $150 and you are having it done every 3 years,
that is $50 per year of sewage treatment. If you are having it
every 2 years it is $75. On the other hand you would pay the
city $300 to $800+ for that same year of treatment. Thinking
about it like that, pumping the tank is pretty cheap.  A good
