Taking care of a septic system in Knoxville
A septic system works quietly until something goes wrong, so a little routine care goes a long way. Pump the tank every few years, keep a record of each visit, and spread out heavy water use like laundry. Keep grease, wipes and harsh chemicals out of the drains. Outside, keep vehicles and new structures off the tank and drain field, and point gutters and sump pumps away from the field.
After heavy rain, check your Knoxville system
Wet seasons put extra pressure on septic systems around Knoxville. If drains run slower after a storm or the ground over the field turns soft, the soil may be saturated. Limit water use for a day and watch whether it recovers. Trouble that persists after the ground dries out needs an inspection.
Picking a septic company that knows Knoxville
Septic work around Knoxville depends on local soil, county rules and the system types common in the area. Ask how often the company works in Knox County and whether they handle your type of system. A good company explains what it found, what it recommends and why, before any work begins.
New construction and septic in Knoxville
Building on a lot without sewer near Knoxville starts with a soil evaluation and a permit from Knox County. The soil test decides what kind of system the lot can support and how large the drain field must be. Some lots need a mound or another engineered system. Get this done before finalizing house plans.
