Discount of 1/2 off is not true. We called and talked to Misty Cox at Middleton Septic. She said the discount that you mentioned is not a true statement. Their price for vault style toilet pumping is $95.00 and they can do several at a time. Septic tanks require a larger truck. Their truck holds 1,500 gallons, and most septic tanks are 1,000 gallons. Therefore, they can only pump one septic tank at a time. Cost for septic tank pumping is $425.00 up to 1,000 gallons. Right now they are completely booked except for emergencies due to the upcoming Eclipse.
