Septic systems in rural Newberry County
Outside the City of Newberry and the town sewer systems, many homes treat their own wastewater with a septic tank and drainfield. Most septic trouble comes from skipped pumping and what goes down the drains.
Last reviewed October 30, 2026 against the sources listed below. General information, not insurance or legal advice.
Inspect and pump on schedule
The EPA says the average household septic system should be inspected at least every three years by a septic service professional, and household tanks are typically pumped every three to five years. Systems with pumps, float switches or other mechanical parts should be inspected more often, generally once a year. How often depends on household size, how much water you use, the solids that go in, and the tank size.
Keep the pumping receipts and a sketch of where the tank lid and drainfield are. You will need them when you sell, and the next pumper will thank you.
Signs of trouble
- Slow drains throughout the house, or gurgling.
- Sewage odor in the yard.
- Wet, spongy or unusually green grass over the drainfield, especially in dry weather.
- Sewage backing up into the lowest drain.
Think at the sink
The EPA's advice for septic owners: avoid chemical drain openers, never pour grease or cooking oil down the drain, keep paints and solvents out, and limit or stop using a garbage disposal, which adds solids that mean more frequent pumping. Only toilet paper should be flushed.
Protect the drainfield
- Do not drive or park on it.
- Plant trees well away from it; roots clog the lines.
- Point roof gutters and sump discharges away from it.
- Spread out laundry over the week rather than doing it all at once.
Permits for repairs and new systems
In South Carolina, septic systems are permitted by the SC Department of Environmental Services. A new system or a major repair needs a permit, and DES requires a final inspection, scheduled by a licensed installer, before the system is covered. Pumping and routine service do not need a permit.
Wells and septic together
Many rural homes have both. A failing septic system can contaminate a nearby well, so test the well if the septic has backed up or the water changes. DES offers well water testing. Well pump problems.
Frequently asked questions
How often should a septic tank be pumped?
The EPA says household septic tanks are typically pumped every three to five years and should be inspected at least every three years.
Can I use a garbage disposal with a septic system?
The EPA recommends limiting or eliminating it. Food waste adds solids, so the tank needs pumping more often.
