Replacing a Failed Septic System
There is a step almost everyone skips, and skipping it can cost up to $30,000: the system has to be declared failing by the county, and that declaration is what opens the funding door.
Process and programme conditions verified August 10, 2026.
A failing septic system does not feel like a paperwork situation. It feels like an emergency — a wet patch that will not dry, a smell, a backed-up fixture — and the instinct is to get somebody out to fix it today.
That instinct is what costs people the money. The Arkansas Septic Tank Remediation Programme requires the system to have been declared failing by an Arkansas Department of Health Environmental Health Specialist as a condition of eligibility. A homeowner who replaces the system first and goes looking for help afterwards may find the qualifying condition can no longer be established — because the failed system no longer exists to be inspected.
The declaration is free, it comes from the county, and it takes a phone call. Making that call before the excavator arrives is the highest-value ten minutes in this entire process.
The order that protects the options
1. Call the county health unit first
Ask for the Onsite Environmental Specialist in the county where the property sits. That is the Department of Health's own standing instruction, and it is the right first call whether or not funding is ever pursued. County contacts for every town in this area are listed on the permit process page.
Two things come out of that call: the possibility of a formal inspection and declaration, and access to the county's list of licensed local individuals who do soil tests and design systems.
2. Retrieve the original permit while you are at it
Ask the same office for the existing septic permit for the property. It helps to know the year the home was built, the subdivision name and the lot number before calling.
The original permit is genuinely useful rather than merely tidy. It indicates what was installed, roughly where, and how it was sized — which tells a Designated Representative whether the system was undersized from the start, whether it has simply reached the end of its life, or whether something changed above ground. A house that gained two bedrooms since the tank went in is a different problem from a field that has silted up.
3. Then the soil evaluation, then the design
Even on a replacement, the soil evaluation comes before the design. The ground may not be what it was assumed to be when the original system went in, standards have changed over the decades, and the reason the old system failed is itself a piece of evidence. What the evaluation involves is covered separately.
Why the declaration is worth the delay
The state remediation programme, funded through the Clean Water State Revolving Fund, provides up to $30,000 per project as a combination of grant money that is not repaid and a zero-interest loan, covering both design and installation by licensed professionals.
It carries two conditions, and the failing declaration is one of them. The other is that the property sits inside a covered watershed — and the covered watersheds lie west and north of this area, so for most addresses here the state programme will not be the route. Which programmes exist, who administers them, and how to check an address is set out in full separately, including the federal routes that are not watershed-limited.
That is precisely why the declaration matters even when the odds look poor. It is free, it takes one call, watershed boundaries follow drainage rather than county lines, and the value of being wrong about it is up to $30,000. Get the declaration; then find out whether it can be used.
The reimbursement shape, and what it means for timing
Where the state programme does apply, it works by reimbursement — the homeowner pays, the work passes county inspection, invoices and the completed permit go to the administrator, and money flows back afterwards. Anyone weighing an emergency repair against a funded replacement should know the funding arrives at the end.
Repair, or replace?
This is a design judgement made by the Designated Representative after looking at the ground, not a preference to be selected in advance. Two things follow from it that are worth knowing.
The permit fee differs. A repair, alteration or extension carries a $30 permit fee. A new installation is priced by structure size, from $30 up to $150 above 4,000 square feet. That difference is small in the context of the job — the money is in the system, not the permit — but it signals which category the work falls into.
The reserve area may be where the new field goes. Arkansas requires every lot to have both a primary and a secondary absorption area sized on natural soil data, and this is one of the situations that requirement exists for. Whether the original location can be reused depends on why it failed; a field that silted up may be rebuildable, whereas one that failed because the soil was never suitable will not be.
On an older property this is also where an unpleasant discovery sometimes surfaces: the reserve area was built over years ago, by a shop, a drive or an extension put up without anyone knowing the ground was spoken for. That does not stop a replacement, but it narrows the options and it changes the number.
Signs worth a call rather than a wait
- Ground over the drainfield that stays soft or green when the rest of the yard is dry.
- Slow fixtures throughout the house rather than in one place.
- Odour outdoors near the tank or field, particularly after rain.
- Surfacing effluent anywhere on the ground.
Surfacing effluent is the one that should not wait. It is the condition the rules exist to prevent, and it is also the clearest evidence for an inspection.
Common questions
An Arkansas Department of Health Environmental Health Specialist, working out of the county health unit. A contractor's opinion that a system has failed is not the same thing, and for assistance-programme purposes only the Specialist's declaration counts.
Because the state remediation programme requires the system to have been declared failing by an Environmental Health Specialist as a condition of eligibility. A homeowner who has the work done first and looks for funding afterwards may find the qualifying condition can no longer be established, since the failed system no longer exists to be inspected.
Call the health unit in the county where the property is located and ask for the Onsite Environmental Specialist. It helps to know the year the home was built, the subdivision name and the lot number. The original permit indicates what was installed, where, and how it was sized.
The fee is. A repair, alteration or extension carries a $30 permit fee, whereas a new installation is priced by structure size from $30 up to $150 above 4,000 square feet. Whether a given job is a repair or a replacement is a design judgement made by the Designated Representative, not a billing preference.
Sometimes, and sometimes the reserve area is used instead. This is one of the practical reasons Arkansas requires every lot to have a secondary absorption area held in reserve. Whether the original location can be reused depends on why it failed and on what the soil evaluation finds, which is why the evaluation comes before the design.
