About Grace Septic

How it works

What’s under your yard.

Most septic trouble starts in one of three places. Knowing which is half the fix.

Cross-section of a septic system in East Tennessee ground: the house line with a clean-out, a two-compartment septic tank with riser lids and baffles, and drain-field trenches in clay above cracked limestone. clean-out septic tank drain field topsoil red clay limestone
  1. 1

    The line & clean-out

    Everything leaves the house through one pipe. The clean-out is where we snake it when it clogs.

  2. 2

    The tank

    Solids sink as sludge, grease floats as scum, and the clearer water moves on. Pumping removes what bacteria can’t break down.

  3. 3

    The drain field

    Perforated pipe in gravel lets the water soak into the soil, which does the final cleaning, here often thin clay over limestone.

A pump-out, step by step

What happens when we come out.

No mystery and no hassle. If you know roughly where the lids are, tell us when you call.

(423) 923-7126
  1. 1

    Call

    Tell us the town, the problem and anything you know about where the tank and lids are.

  2. 2

    Find the lids

    We locate and uncover the tank lids. Risers make the next visit quicker.

  3. 3

    Pump it out

    Sludge and scum come out of every compartment into the truck.

  4. 4

    Look while it’s open

    We check the water level, the inlet and outlet and the tank’s condition.

  5. 5

    Close it up

    Lids go back on secure, and we tell you what we saw and when to pump again.

When to call

Six signs your septic system wants attention.

  • Slow drains everywhere

    When every sink, tub and toilet slows at once, the problem is usually past the house: the line, the tank or the field.

  • Gurgling pipes

    Air bubbling back through a drain after you flush often means the line or tank is getting full.

  • Sewage odor outside

    A septic smell over the tank or the field, especially after rain, is worth a call.

  • Wet, green stripes

    Soggy ground or grass that stays greener over the drain field can mean the field is overloaded.

  • Backup in the lowest drain

    A basement shower or floor drain is usually first. Stop using water and call.

  • Years since the last pump-out

    If you can’t remember when the tank was last pumped, it’s probably due.

Never enter a septic tank or lean into an open one. Septic gases and low oxygen can kill in minutes, rescuers included. Keep lids secure and children and pets away. Sewage in the house? Stop using water, keep everyone out of the area, and call.

Local knowledge

Ridge, valley and lake: the ground decides a lot.

The Holston valley is Valley and Ridge country. Long ridges of shale and sandstone run southwest to northeast, with limestone valleys between them, and Cherokee Lake now fills the river’s old bottomland. Soil can be deep red clay in one field and a few inches over rock in the next.

That matters for a drain field, which needs enough soil to clean the water before it reaches the cracked limestone below. It also matters for permits: Hawkins County goes to one TDEC office, Hamblen and Grainger to another.

Straight answers

Septic questions, answered.

How often should a septic tank be pumped in East Tennessee?

Most household septic tanks need pumping every three to five years. A smaller tank, a bigger household, a garbage disposal or a lot of laundry pushes that toward the short end.

What are the signs a septic system is failing?

Slow drains all over the house, gurgling pipes, sewage smell outside, wet or extra-green ground over the drain field, and sewage backing up into the lowest drain.

Who permits septic systems in Hawkins, Hamblen and Grainger counties?

The Tennessee Department of Environment and Conservation (TDEC), Division of Water Resources. Hawkins County is handled by TDEC’s Johnson City field office; Hamblen and Grainger counties by the Knoxville field office.

Why is septic harder in the Holston valley than in some places?

Because the ground here is the Valley and Ridge: long parallel ridges and valleys of folded limestone, dolomite and shale. Soils are often shallow over rock, rocky or cherty, or tight red clay, and the limestone underneath is full of cracks, sinkholes and springs.

How often does a restaurant grease trap need pumping?

It depends on the size of the trap and how much grease the kitchen produces. A common rule is to pump it before the grease and solids fill a quarter of its depth; for many busy kitchens that means every one to three months.
