Septic Service Across East Texas

East Texas Septic Service helps homeowners, landowners and businesses across eight East Texas counties (Smith, Gregg, Harrison, Rusk, Upshur, Van Zandt, Wood and Cherokee) with septic pumping, repair and installation. Several towns straddle county lines: parts of Longview sit in Harrison County, parts of Kilgore in Rusk County and part of Gladewater in Upshur County, so the county that permits your system can differ from your mailing address. Gilmer is the Upshur County seat, and Henderson is the Rusk County seat. Most homes inside city limits are on municipal sewer, so septic systems are the rule on the edges of town and the rural county roads beyond them. Each town page covers who issues septic (OSSF) permits there, where septic systems are common, and the problems homeowners there most often need help with. By county: Smith runs its OSSF program through a contractor, RTS Environmental LLC, based in Tyler. Gregg permits through the Gregg County Health Department in Longview. Harrison permits through Harrison County Environmental Health in Marshall. Rusk has a designated representative at the courthouse in Henderson. Upshur permits through the Northeast Texas Municipal Water District. Van Zandt permits through the county Fire Marshal’s office in Canton, with no exemption for large tracts. Wood permits through its authorized agent in Quitman. Cherokee permits through its authorized agent in Rusk, except inside Jacksonville, where the city is its own authorized agent.
