Longview, Gregg County
Septic Service in Longview, TX
Longview sits across two counties, Gregg and Harrison, so which office permits your septic system can depend on which side of the line you're on.
Septic service in a two-county city
Longview is unusual on this list because the city itself straddles a county line. The main part of Longview, including its downtown and county seat functions, is in Gregg County. A smaller annexed section of the city extends into Harrison County. That split matters for septic service, because on-site sewage facility (OSSF) permitting in Texas happens at the county level, and Longview effectively has two.
If sewage is coming up inside the house right now, don’t wait on paperwork questions.
Which county handles your permit
On the Gregg County side, the Gregg County Health Department issues OSSF permits and reviews site evaluations for new systems and replacements. On the Harrison County side, Harrison County Environmental Health handles that role instead, and also maintains a list of approved designers and installers. If you’re not sure which county your address falls in, the company you’re connected with can usually help you confirm it before you start a permit application.
City sewer versus septic around Longview
Inside Longview’s city limits, most residential and commercial properties run on municipal sewer. Septic systems become more common as you move outward, past the city limit line and into unincorporated Gregg or Harrison County land, including areas toward Lake o’ the Pines roughly 25 miles northeast. Older Longview neighborhoods that predate a sewer extension can also still have a legacy septic system even though they’re technically inside city limits, so age of the home matters as much as location.
Typical septic calls around Longview
| Call type | What it usually involves |
|---|---|
| Pumping | Routine tank pumping, plus emergency pumping for a tank showing signs of being full |
| Aerobic maintenance | Alarm checks, spray head clearing, chlorine tablet service |
| Repair | Drain field failure, line breaks, backups into the home |
| Inspection | Real estate sales, refinancing, or a system with an unknown history |
| Installation | New construction or full system replacement, starting with a site evaluation |
Longview’s mix of an established urban core and a wide rural county footprint means both ends of that table stay busy: older in-town systems needing repair, and newer rural or lake-area properties needing installation or aerobic service.
Getting the right help
Because Longview crosses a county line, tell the person you’re connected with exactly where your property sits, including whether you’re inside city limits. That one detail can change which permitting rules and which local office apply to your job, and a company that regularly works in both Gregg and Harrison counties will already know the difference.
Older neighborhoods versus newer additions
Longview’s growth over the decades has happened in waves, and that shows up in its septic systems. Neighborhoods that predate a nearby sewer extension sometimes still run on an old conventional tank even though newer streets around them are fully on city sewer. Those older systems are the ones most likely to need a full inspection before anyone assumes they’re still working correctly, especially if a property has changed hands more than once without anyone tracking service history.
If you’re not sure which county you’re in
It’s a fair question, since Longview’s boundary with Harrison County isn’t something most residents think about day to day. If you’re unsure, look at your property tax statement or ask the company you call to confirm before scheduling a permit-related visit. For a straightforward pumping or repair call, it usually doesn’t change anything about how quickly someone can get to you.

Common questions
Is Longview one county or two?
Longview's main body and county seat functions sit in Gregg County, but the city also extends into a smaller annexed portion of Harrison County. Which county your property sits in can affect which office handles septic permitting.
Who issues septic permits in Longview?
For the Gregg County side, the Gregg County Health Department handles on-site sewage facility (OSSF) permits under state rules (30 TAC Chapter 285). For the Harrison County side, Harrison County Environmental Health handles permits. Confirm with the appropriate county office based on your address.
Does everyone in Longview have city sewer?
Most homes inside Longview's city limits connect to municipal sewer. Properties outside the city limits, including many homes toward Lake o' the Pines and the surrounding county, are more likely to be on a septic system.
How often should a Longview septic tank be pumped?
Pumping frequency depends on tank size and household size, but most conventional tanks need it every few years. If you don't know when yours was last pumped, that's a good reason to schedule a check.
What does a septic company look for on an older Longview property?
On older lots, a septic company typically checks tank condition, drain field performance and whether the system was ever properly permitted, since older rural properties sometimes predate current recordkeeping.
