How Septic Tank Pumping Works Across Midland County
A conventional septic system starts with a buried tank that takes in everything that leaves the house. Solids sink and form sludge at the bottom, grease and light material float as scum on top, and the middle liquid flows out to the drain field. Bacteria break down some of the waste inside the tank, but they cannot break down everything, so the sludge layer slowly builds up over the years.
Pumping means a crew uses a vacuum truck to remove the sludge and scum. Once the tank is empty, a good crew checks for cracks, damaged baffles and the condition of the outlet, and many also look at the effluent filter if the tank has one. Ask each company whether the inspection is part of the price, because some quotes cover pumping alone and leave the rest for a separate visit.
