Septic service in Ooltewah, Harrison and Apison

These are unincorporated parts of eastern Hamilton County. Sewer here is WWTA's, it reaches some streets and not others, and septic permits come from the County.

How this works: Chattanooga Septic Quotes is a free referral service, not a septic company. We pass your request to independent local septic pros, who may pay us for the referral. They quote, schedule and do the work; check their insurance before you hire. More about us.

Sewer is street by street

WWTA serves the unincorporated county and treats Ooltewah as its own sewer service area. Its pump stations include Harrison Bay and Harrison Ooltewah, and it lists Apison and Ooltewah among current project areas. Whether your street has a line is a question for WWTA (423-209-7842).

If sewer reaches you

WWTA says state law (TCA 7-35-201) lets it require a home to pay sewer charges, stop using its septic system and connect when sewer is available. If you are buying a home here, ask whether a sewer line already runs past it.

New homes and additions on septic

A new septic system needs a $440 Hamilton County permit, and a lot review for a plat is $150 per lot plus $5. For an addition on an existing system, the County requires it to sit at least 5 feet from the tank and 10 feet from field lines. In-ground pools, or cuts deeper than a foot, need 25 feet from the field lines.

What a new system costs

Angi's 2026 national figures: most new systems run $3,590 to $12,463, conventional systems $3,000 to $8,000, and aerobic units $10,000 to $20,000, plus $700 to $2,000 for a perc test.
