| All tanks used in North Carolina (septic, pump and grease) must be approved by the On-Site Water Protection Section prior to being installed for use as an on-site system. The section's engineers review the tank plans. Approved tanks are identified with an
septic tank with baffle or pump tank identification number. The STB or PT ID number includes the tank manufacturer name or abbreviation, the STB or PT number assigned by the state and the tank volume. Contact the health department in your county for assistance with issues relating to tanks. |
