Frequently Asked Questions

A septic system is an underground wastewater treatment structure that uses a combination of natural bacterial processes and gravity to treat household wastewater. Waste flows into the septic tank, where solids settle to the bottom (sludge) and oils float to the top (scum). The clarified liquid (effluent) exits into the drainfield, where soil microbes provide final treatment before the water returns to the groundwater cycle.

Most homes in Middle Tennessee need pumping every 2–5 years. The exact interval depends on tank size, household size, water usage, and whether you use a garbage disposal. Large families or homes with small tanks may need service every 1-2 years, while low-occupancy homes can often wait 5 years. Staying on schedule prevents backups and protects your drainfield.

Warning signs include: • Slow drains or gurgling sounds in plumbing • Sewage odors inside or outside your home • Wet, spongy ground or noticeably green grass over the drainfield • Sewage backing up into household drains • Elevated nitrate or bacteria levels in well-water tests Addressing issues early can help to avoid costly repairs.

Best practices include: • Schedule regular inspections and pumping • Use water efficiently (install low-flow fixtures, fix leaks) • Keep non-biodegradable items and grease out of drains • Direct roof and surface water away from the drainfield • Keep vehicles, heavy equipment, and deep-rooted plants off the drainfield These habits reduce system overload and prevent clogs.

Never flush or pour into your drains: • Cooking grease or oil • Non-biodegradable wipes (including items labeled as flushable), paper towels, cotton swabs, feminine products • Harsh chemicals (paint, pesticides, solvents) • Medications • Coffee grounds, cat litter, or large amounts of bleach These items disrupt bacterial balance and can clog the system.

Most modern toilet paper brands break down quickly in water. "Septic-safe" labels are helpful, but using reasonable amounts and avoiding ultra-thick or lotion-infused paper matters more. If in doubt, place a sheet in water - if it disintegrates within a few minutes, it's suitable.

No, at Outright we are focused on septic cleaning, pumping and inspection.

That's a bit of a trick question! Your tank is actually designed to run full with water! The water separates the scum on top and the sludge on the bottom. It is the effluent water in the middle that makes its way to the drainfield. However, if you wait too long to pump your septic tank, the sludge/scum will close the gap and begin to clog the drainfield, causing serious (and sometimes irreparable) damage. Here are some common indicators that the sludge and/or scum in your tank is too full: • Slow-draining sinks or toilets • Gurgling sounds in plumbing lines • Wet spots or lush grass directly over the tank or drainfield • Sewage odors in the yard Contact Outright today and we can assist you in determining if a routine cleaning is needed or you have a more urgent issue.

A full maintenance visit generally covers: • Pump-out and legal disposal of solids • Inspection of visible baffles, inlet/outlet tees, and filter (if present) • Checking visible areas of the tank for cracks or root intrusion • Assessing flow from the drainfield • Written report of observed conditions and amount of waste removed

Yes. More occupants or high-volume water appliances (Jacuzzi tubs, large washing machines) send extra wastewater to the tank, shortening the pump interval to as little as 1-2 years. Water-saving fixtures and spreading out laundry help keep a 2–5-year schedule.

Use biodegradable, phosphate-free cleaners in moderation. Avoid or limit: • Large doses of chlorine bleach • Antibacterial soaps and wipes • Solvents or drain cleaners These chemicals can kill beneficial bacteria and upset tank chemistry.

Regular use of a garbage disposal can increase the amount of solids entering the tank by up to 50%. If you grind food scraps daily, plan on more frequent pumping (every 1–2 years) or compost food waste instead.

Key red flags include standing water or soggy soil, sewage odors, unusually green or lush grass, and toilets backing up soon after pumping.

A slight whiff right after pumping is normal. Ongoing odors means something's leaking, a lid is loose, or the drainfield is saturated. Schedule an inspection promptly to protect your health and the environment.

Flooded or saturated soil slows effluent absorption, which can cause backups inside the home. During and immediately after heavy rains, reduce water usage and monitor for slow drains. If problems persist, have the system pumped and inspected.

Plant only shallow-rooted grass or flowers over the field. Keep trees and shrubs at least 20 feet away, avoid vegetable gardens or raised beds, and never till or add fill soil over the drainfield.

No. Vehicle weight can crack the tank and crush drainfield pipes. Mark the area with landscaping or low fencing to keep cars and heavy equipment away.

A concrete septic tank can last 40 years or more, while a well-cared-for drainfield typically lasts 25–30 years. Neglecting pumping and maintenance can cut those lifespans in half.

Stop using water and call our office immediately. Avoid chemical drain cleaners, which can worsen the blockage. Quick professional intervention can help to limit system damage and health risks.

Yes. Overflowing tanks can release pathogens and excess nutrients into groundwater and nearby streams, threatening wells and ecosystems. Timely maintenance protects public health and property values.
