New Septic Systems for Harahan Properties
Replacing a failed system or installing one for a new build in Harahan involves more than digging a hole for a tank. Soil testing, system design, permits and inspections all shape the final result.
A local installer can tell you which system types are likely to work on your lot and what the process looks like.
The installation process step by step
It starts with testing the soil to see how well it absorbs water. A designer or engineer then sizes the tank and dispersal area for the number of bedrooms. After the permit is approved, the crew excavates, sets the tank, installs the pipes and field, and schedules an inspection before backfilling.
Choosing the right system
The best system is the one your soil and lot can support. Good, deep soil often allows a conventional system. Clay, high groundwater or shallow bedrock may call for a mound, pressure distribution or an aerobic unit. Each has different costs and maintenance needs, so ask your installer to explain them.
Approvals you will need
Plan on a permit for any new or replacement system. Regulators typically want a site evaluation, a design that meets local code and an inspection before the system is covered. Your installer or designer often handles the paperwork, but the permit is tied to your property, so keep copies.
What you are paying for in a new system
A new system quote covers the soil evaluation and design, permits, the tank, pipe and field materials, excavation and backfill, and the final inspection. Ask whether site restoration such as grading and seeding is included, and whether the quote assumes a conventional system or an engineered one.
After installation
Ask your installer for records, maintenance instructions and warranty details. Mark the tank and field location so they are not damaged by future projects. Some systems require a service contract, so confirm what applies to yours.
Questions to ask an installer
Ask who performs the soil evaluation and design, whether they handle permits, what system types they recommend and why, and how long the project will take. Ask about warranty terms and what maintenance the system will need.
How long a new system takes near Harahan
Soil testing, design and permit review usually take longer than construction. In Jefferson Parish, wet seasons and frozen ground can delay soil evaluations, and review times vary through the year. Once the permit is in hand, most installations take a few days to a couple of weeks.
Mistakes to avoid on a Harahan installation
The most expensive mistakes happen before the digging starts. Skipping the soil evaluation, choosing a system on price alone, or placing the drain field where future driveways, pools or additions will go all lead to trouble later. Undersizing the tank for the number of bedrooms is another common one. Ask your Harahan installer to walk you through the site plan and explain why each part sits where it does.
Replacing an old system in Harahan
When a system near Harahan fails, replacement often means a new drain field in a fresh part of the yard. The old tank may be pumped, crushed and filled, or reused if it is sound. Jefferson Parish usually requires a permit and a final inspection. Ask for the as-built drawing once the work is done.
What Harahan's soil means for a new system
The USDA soil survey rates most mapped soils near Harahan as very limited for septic absorption fields. New systems here often need a mound, pressure distribution or another engineered design, which your soil test will confirm. With about 60 inches of precipitation a year, designers here account for high water tables and runoff when sizing and placing a system.

Among the mapped soils within about two miles of central Harahan, the USDA soil survey rates 100% as very limited for septic absorption fields, 0% as somewhat limited and 0% as not limited. The most common drainage class is poorly drained.

Septic Installation questions in Harahan
- How long does septic installation take?
- Installation itself often takes a few days to two weeks. Soil testing, design and permit review can add several weeks, so plan ahead.
- What is a mound system?
- A mound system raises the drain field above the natural soil using sand and fill. It is used where the soil is too shallow, too wet or too slow draining for a conventional field.
- Can a replacement system go in the same place?
- Sometimes. It depends on the condition of the soil in the old field and local rules. Many replacements use a new area of the yard.
- Is SepticTank.com the installer?
- No. SepticTank.com connects you with an independent local septic company that serves Harahan. That company designs, installs and prices the system.
