615 Septic Tank Pumping is a septic tank pumping company serving Nashville and Davidson County, Tennessee, and drain field repair is one of the services it provides across the county. Diagnosis and repair of fields that have stopped accepting effluent — and an honest read on whether yours is repairable or heading for replacement.

When people call us about this

These are the situations that bring most drain field repair calls in:

  • Standing water or soft ground over the field
  • Effluent surfacing after rain or heavy household use
  • Grass over the field markedly greener and faster-growing
  • Drains slow again within weeks of a pump-out
  • Odour over the field that does not clear

What is included

Every drain field repair job includes all of the following. Nothing on this list is an upsell presented once we are on site.

  • Diagnosis of whether the fault is the tank, the outlet, the distribution box or the field
  • Tank pumped down to take hydraulic load off the field during assessment
  • Distribution box located, opened and checked for level and blockage
  • Laterals assessed for biomat, root intrusion, crushing and saturation
  • Assessment of whether the failure is loading, mechanical or soil-driven
  • Karst and sinkhole features noted where they threaten the field
  • Reserve area assessed against the parcel, in case replacement becomes necessary
  • Written repair-or-replace recommendation with cost bands for both routes

What it costs, and what moves the price

National rejuvenation and repair figures run $1,000–$5,000; Nashville-area drain field repair is reported from $2,000 to above $10,000, and Tennessee replacement runs $7,000–$15,000+ because Middle Tennessee's slow-draining soils demand larger fields.

The published range for this service is $1,000–$5,000 for rejuvenation and localised repair; $7,000–$15,000+ if the field needs replacing. We give you a band before we come out and a firm number before we do anything that changes it. If you want a figure right now without talking to anyone, the cost estimator takes three questions.

How drain field repair runs, start to finish

  1. 01

    Rule out the cheap causes first

    A failed outlet baffle or a clogged effluent filter produces symptoms that look exactly like a failing field, and costs a fraction to fix. We check those before anyone talks about excavation.

  2. 02

    Take the load off

    The tank is pumped down so the field stops receiving flow, which both relieves the immediate problem and lets us see how the field behaves when it is not being pushed.

  3. 03

    Open the distribution box

    An unlevel or blocked distribution box sends everything to one lateral and drowns it while the rest of the field sits unused. It is common, cheap to correct, and frequently missed.

  4. 04

    Honest repair-or-replace call

    Some fields recover once the cause is removed. Some are finished. You get the assessment with both cost bands, and we will tell you when spending on a repair is throwing money at a field that needs replacing.

Doing it yourself, hiring cheap, and doing it properly

The difference between a cheap pump-out and a proper one is not the truck. It is whether anybody looked inside the tank while it was empty.

  Doing it yourself Cheapest quote Done properly
Solids actually removed Surface liquid only — no way to remove settled sludge Liquid draw-down; tank looks emptied, sludge stays Liquid, scum and sludge pumped, then backflushed
Baffles inspected Not visible without emptying the tank Rarely — the tank is not pumped down far enough to see them Both baffles inspected while the tank is empty, and reported
Effluent filter Usually not known to exist Left alone Removed, rinsed back into the tank, inspected, replaced if split
Interval set by Guesswork or a number off the internet A flat three years for every customer Measured sludge and scum depth against your tank capacity
Disposal of septage No lawful route for a homeowner Varies — ask where it goes Licensed disposal under Tennessee pumping contractor rules
What it costs Nothing up front Slightly less than proper $300–$525 typical
What it risks Solids reach the drain field. Field replacement $7,000–$15,000+ Same failure, delayed. The field pays for the saving The field is what you are protecting

Cost Guide

What does drain field replacement cost in Tennessee?

The five-figure number at the end of every neglected septic system, and what actually drives it.

Decision Guide

Can a failing drain field be repaired instead of replaced?

Sometimes yes, and the difference is thousands of dollars. Here is how the decision is actually made.

Rules & Permits

Why do drain fields in Middle Tennessee have to be bigger?

Karst geology, shallow soil over limestone, and an eighty-year-old county regulation that still shapes your yard.

Rules & Permits

Does a sinkhole near my drain field matter?

Two distinct risks, one of them invisible — and why a field that never looks wet can still be failing.

What To Do Now

There is standing water over my septic tank — is it an emergency?

Urgent, and in Middle Tennessee it is a groundwater question as well as a yard one.

Drain Field Repair — questions people ask

What does drain field repair cost in Middle Tennessee?

Rejuvenation and localised repair typically run $1,000–$5,000, and Nashville-area repair has been reported from $2,000 to above $10,000 depending on severity and access. Full replacement in Tennessee runs $7,000–$15,000 and up. Middle Tennessee fields sit at the larger end of the sizing range because the soils drain slowly, which pushes replacement costs above national averages.

Can a failing drain field be repaired instead of replaced?

Sometimes. If the cause is a fixable upstream fault — a failed baffle sending solids to the field, an unlevel distribution box, a filter nobody cleaned — removing it and resting the field can restore function. If the soil interface is biomat-sealed across the field after years of solids, repair is deferral rather than a fix, and we will say so.

Why do drain fields in Middle Tennessee have to be bigger?

Because the soils here drain slowly. Middle Tennessee is karst country — shallow clay loam over fractured limestone — and slow percolation means a given daily flow needs more absorption area. Local drainfields skew to the large end of the sizing range, which raises the cost of replacing one.

Does a sinkhole near my field matter?

Yes. Fractured limestone lets poorly treated effluent reach groundwater without the filtration a proper soil column provides, and a sinkhole can undermine a field directly. County environmental health offices across Middle Tennessee enforce setbacks from visible solution features for exactly this reason.

How do you price the work, and will the price change once you are here?

You get a range before we come out, based on your tank size and how buried the lids are. Tennessee pumping runs $275–$525 and Davidson County figures span $199–$796, so the honest answer is that access and capacity move it. If we open the tank and find something that changes the job — compacted sludge needing a clean, a corroded baffle, a split effluent filter — we tell you what it costs and let you decide before we do it. We do not do the work and present the bill afterwards.
