Septic companies in Louisiana

Louisiana permits septic from the state, at a parish health unit staffed by state sanitarians, under Title 51 of the Sanitary Code. Two things make this state different: the Department of Environmental Quality is a second regulator, because so many Louisiana systems discharge to a ditch and need their own permit, and the state's own pumping interval is longer than the federal advice. This guide covers the three licence types, which one your job needs, both permits, and what the code actually asks of you between visits.

Who Regulates Septic Systems in Louisiana

Sources: Louisiana Department of Health; Louisiana Department of Environmental Quality. Checked 2026-09-18.

Louisiana has parishes rather than counties, and the office you want sits in yours. It is a parish health unit, which is a state facility rather than a parish government one. Two state agencies are involved, and which one you need depends on where your treated water ends up.

Sanitarians located in the health units of each parish inform, advise and operate a permitting system with regard to onsite sewage treatment opens in a new tab, and the Office of Public Health operates parish health units in each of its regions as the hub for that parish's public health needs opens in a new tab. So the building is a state one even though it carries your parish's name.

The rule has a name worth knowing when a contractor cites it. The Louisiana Sanitary Code was codified and re-promulgated as Title 51, Public Health Sanitary Code, effective 20 June 2002 opens in a new tab, and the Onsite Wastewater Program licenses and regulates onsite wastewater treatment system installers, haulers, sub-manufacturers and manufacturers in this state opens in a new tab.

The second agency matters whenever a system discharges rather than soaking away. Anyone proposing to discharge pollutants from a point source to waters of the state must have an effective LPDES permit when the discharge begins opens in a new tab, and the health department tells applicants that state law requires that discharge permit from the Department of Environmental Quality opens in a new tab.

Licenses and What to Check Before You Hire

Sources: Louisiana Department of Health; Louisiana Department of Environmental Quality. Checked 2026-09-18.

Louisiana issues three licences and the one your contractor needs depends on what is going in the ground. Three types of licenses are issued by the Onsite Wastewater Program: Basic, Combination and Maintenance, issued on an annual basis opens in a new tab.

The split is clean and easy to check on the phone. A basic license is required to install a septic-tank system, and a combination license is required to install an aerobic treatment unit opens in a new tab. The Basic licence is required by Title 51, Part 13, Subchapter C, section 737.A for the installation and maintenance of septic tanks opens in a new tab.

The third licence covers servicing rather than installing, which is easy to miss. The Maintenance licence, under section 737.C, is for the maintenance of mechanical treatment plants opens in a new tab and not for installing them. A company holding only that one cannot put your system in.

Behind all three sits a training requirement with a pass mark and an expiry. The Sanitary Code requires a minimum workshop exam score of 70% opens in a new tab, and every five years an installer must retake the training class and pass the exam to avoid an interruption of licensure opens in a new tab.

Pumping brings in the other agency again, with a different instrument. The Department of Environmental Quality requires a Sewage Sludge Hauler Registration for the person responsible for the operations of sewage sludge transport activities opens in a new tab. A registration is not a licence, and DEQ is not the health department, so ask which one the company holds.

On a mechanical system, the brand matters as much as the licence. LDH maintains a list of installers with active endorsements from a system manufacturer, and advises choosing a maintenance provider who has an endorsement for your system opens in a new tab. We hold no Louisiana register of our own, so no listing here carries a verified credential for this parish, and those LDH lists are where a claim gets checked.

Permits, Inspections and Selling a Home

Sources: Louisiana Department of Health. Checked 2026-09-18.

Approval comes before the work, and for a house it is a local counter. The State Sanitary Code requires that prior to the start of constructions, approval by the Louisiana Department of Health be obtained for plans and specifications opens in a new tab, and for smaller projects the plans and specifications must be submitted to the local parish health unit in your area opens in a new tab.

The form has a name, and knowing it saves a conversation. Authorisations are attached to the Application for Permit for Installation of On-Site Wastewater Disposal System opens in a new tab, which is form LHS-47. Effluent reduction systems shall be installed by a licensed installer, and existing field lines cannot be used as the effluent reduction system opens in a new tab.

On a mechanical plant the job closes with a certificate. The installer certifies that the sewage treatment plant was manufactured, outfitted and installed in accordance with the NSF Standard requirements opens in a new tab. Ask for that document, because it is the record that the plant was set up to its own standard.

On selling, we found no state rule requiring a septic inspection when a property changes hands. What the state does prohibit is the discharge of effluent from any plumbing fixture, vault, privy or portable toilet where the code forbids it opens in a new tab, which is the condition a buyer should be checking for. To date, 57 of the 64 parishes in Louisiana have enacted onsite sewage ordinances opens in a new tab, so ask the parish health unit what it requires locally as well.

Keeping a System Working

Sources: Louisiana Department of Health; U.S. Environmental Protection Agency. Checked 2026-09-18.

Louisiana's own interval is longer than the federal one, so use the state figure and treat the federal as the cautious version: septic tanks should be inspected every six years and pumped at least every eight years by a licensed sewage hauler opens in a new tab, against the EPA's inspection at least every three years and pumping typically every three to five opens in a new tab. A mechanical plant is a different commitment: its initial policy contains four inspection and service visits scheduled once every six months over two years opens in a new tab, and homeowners are required to maintain their systems in perpetuity opens in a new tab.

Help Paying for Repairs

Sources: Louisiana Department of Environmental Quality; U.S. Environmental Protection Agency; Louisiana State Licensing Board for Contractors. Checked 2026-09-18.

Louisiana's state fund is not written for households, and its own page says who it expects to hear from. The Clean Water State Revolving Fund provides low interest loans to finance eligible projects and bring them into compliance opens in a new tab, and it invites elected officials, consulting engineers, bond attorneys and other professionals to make contact opens in a new tab.

The money that reaches one house is federal. Grants and low interest loans repair, improve or modernise rural single family homes, with grants for elderly very low income owners opens in a new tab, and grant funds can help a nonprofit create a revolving loan fund for owner occupiers in an eligible rural area opens in a new tab. Individual homeowners are not eligible to receive 319 grant assistance directly opens in a new tab.

One more cost to budget for, because it is a separate trade. Louisiana's contractor board sets a home improvement threshold covering work on a residence or dwelling unit and adjacent structures opens in a new tab, so a larger job can need a contractor licence as well as the onsite wastewater one.

Questions People Ask

Who issues a septic permit in Louisiana?

The state, at your parish health unit. Sanitarians in the health unit of each parish operate the permitting system for onsite sewage, and those units are Office of Public Health facilities rather than parish government offices. The form is the LHS-47.

Which licence does my installer need?

It depends on the system. A basic license is required to install a septic-tank system, and a combination license is required to install an aerobic treatment unit. A maintenance licence covers servicing mechanical plants and does not cover installation.

Do I need a permit from DEQ as well?

If your system discharges, yes. Anyone discharging pollutants from a point source to waters of the state must have an effective LPDES permit when the discharge begins, and the health department tells applicants that state law requires it. That is common in Louisiana because many systems discharge to a ditch.

How often should my tank be pumped?

Louisiana's own code says septic tanks should be inspected every six years and pumped at least every eight, by a licensed sewage hauler. The EPA's more cautious guidance is an inspection every three years and pumping every three to five. A mechanical plant needs servicing far more often than either.

Do I need an inspection to sell my house?

We found no state rule requiring one. But 57 of the 64 parishes have enacted their own onsite sewage ordinances, so if there is a requirement where you live it will be a parish rule. Ask your parish health unit.
