The cost to pump a septic tank typically ranges from about $250 to $700 on average, but it can vary widely depending on tank size, location, and other factors. Here are key details:

• Average cost nationwide is around $400 to $423 per pumping

• Smaller tanks (around 600 to 750 gallons) can cost as little as $100 to $300 to pump, while larger tanks (1,500 to 2,000 gallons) may cost $450 to $1,100 or more

• Typical cost ranges by tank size:
  • 750 gallons: $175–$550
  • 1,000 gallons: $325–$700
  • 1,250 gallons: $375–$900
  • 1,500 gallons: $450–$1,100
  • 1,750 gallons: $550–$1,250

• Location impacts cost significantly; urban areas and places with difficult tank access or deep burial increase costs. For example, pumping in Portland, OR, can cost $440–$750, while in Minneapolis, MN, it may be $175–$275

• Additional factors affecting cost include tank accessibility, presence of multiple tanks, frequency of pumping, and any extra services like filter cleaning or emergency calls

• Regular pumping every 3 to 5 years is recommended to avoid costly repairs from sludge buildup

In summary, expect to pay roughly $300 to $500 for standard septic tank pumping, with prices varying based on tank size and location. Smaller tanks cost less, larger tanks more, and difficult access or urban settings can increase fees.
