Septic tank pumping generally costs about $150-$300, depending on the size of the tank and the distance to the septic pumping truck. Some companies may charge more if they have to travel a long way to your house, or if your tank is particularly large. Septic tanks should be pumped out every 2-3 years, as part of regular preventative maintenance. Pumping out the tank removes all of the solids that have built up in it over time, which helps to keep the septic system running smoothly. If you do not pump out your tank on a regular basis, eventually all that solid waste will start to back up into your house and cause some pretty nasty problems.

Septic tank pumping costs vary depending on the size of the tank, the number of gallons it holds, and the distance to the nearest septic pumping station. Typically, you can expect to pay between $75 and $150 for this service.Some homeowners choose to have their tanks pumped every year, while others wait two or three years. It's important to remember that if you wait too long between pumpings, solid waste will accumulate and clog up the tank, leading to expensive repairs down the road.
