We had our septic tank cleaned last Spring (before all the heavy rain thankfully) We had a few quotes ranging from $210 up to $304. We chose the lower priced. They came that day and charged the price that was quoted over the phone. They asked in which direction the septic lines went before proceeding to drive so as not to drive over the septic field with their heavy truck. We timed it right because several of our neighbors had septic problems and flooding last spring but we had no problems.
