Septic service in Hixson

Hixson addresses can be inside Chattanooga city limits or in unincorporated Hamilton County. Septic permits come from the County either way; sewer depends on which side of the line you are on.

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.

Who runs the sewer near you?

WWTA runs public sewer in unincorporated Hamilton County but says it is not responsible for sewers inside the City of Chattanooga. So a Hixson address inside the city and one outside it can have different sewer providers, and homes in both areas can be on septic. WWTA (423-209-7842) can tell you whether a sewer line serves an unincorporated address.

Find your existing septic permit

Hamilton County Groundwater Protection keeps septic permits and installation certificates. Owners can request a copy by email (gwp@hamiltontn.gov), and anyone can search the County's online document retrieval by street name. The permit usually shows the tank and field-line layout, which helps a pumper find the tank.

Repairs need a permit

Repairing an existing septic system in Hamilton County needs a $40 repair permit from Groundwater Protection. Adding bedrooms or field lines is a $440 modification permit.

Before you dig

Tennessee 811 requires a locate ticket at least 3 working days before digging, which includes uncovering a tank or trenching a new field line. 811 does not mark private lines.
