- Pump up to 1000 gallons (additional fee per 100 gallons) Upon arrival I spoke with the homeowner and they showed me the general location of the septic tank and their pump station. After digging up the septic tank I gave the homeowner’s multiple upfront options on getting it pumped. The homeowner’s decided on option 4 and I began pumping the tank until it was clean and clear. Upon completion I cleaned up all tools and materials.
