Septic Tank Pumping in Johnston County, NC

Routine pumping removes the sludge and scum layers that build up in your tank. If solids get too deep, they can flow out into the drain field and clog it, which is the most expensive part of a septic system to repair.

How often should a septic tank be pumped?

The U.S. EPA's general guidance is that most household tanks should be inspected about every 3 years and pumped about every 3 to 5 years. The right interval for your home depends on tank size, how many people live there, water use, and whether you use a garbage disposal.

Signs your tank may need pumping

• Slow drains or gurgling plumbing
• Sewage odors near the tank or drain field
• Unusually green, soggy grass over the drain field
• Water or sewage backing up into the lowest drains

What to know before the truck arrives

• Know where your tank lid is. Your system's permit or as-built drawing on file with Johnston County Environmental Health may show its location.
• Tanks should be pumped through the lid or riser, not through the inspection port.
• Ask the contractor to note the condition of the baffles and the effluent filter, if you have one.
