Our published Greenville County rates as of June 2026 are $450 for a 1,000-gallon tank, $575 for a 1,250-gallon tank, $575 for a 1,500-gallon tank and $850 for a 2,000-gallon tank. EPA puts regular septic maintenance at $250 to $500 every three to five years (as of September 2026). A buried lid or an emergency call can raise the price, so call 864-431-2822 and we'll quote it before a truck rolls.
