Drain Field Replacement Cost Near Nueces County | Septic Guide
1. Why You’re Probably Here: A Drain Field Problem That Won’t Go Away
If you’re reading this, chances are something’s off with your septic system. Maybe your yard has turned into a swamp. Maybe the toilet keeps backing up, or the drains are moving slower than molasses. And you’re wondering—Is it the drain field? Is this going to cost me a fortune?
You’re not alone. Many homeowners in Nueces County and surrounding areas have been in your shoes. It’s confusing, stressful, and frankly, a little overwhelming. You don’t want to make a bad decision, but you also don’t want your backyard to smell like sewage all summer.
At B5 General Contracting LLC, we work with folks just like you—families who rely on their septic system every day and just want things to work. We’re based right here in Alice, Texas, and we serve most of Nueces, Jim Wells, San Patricio, Live Oak, Duval, Kleberg, and Aransas Counties. We’ve seen it all. And this guide? It’s our way of helping you understand what’s really involved in drain field replacement—and how much it actually costs.
2. What Is a Drain Field, and Why Does It Matter So Much?
Let’s keep this simple.
Your septic system has two main parts: the septic tank and the drain field (also called a leach field). The tank holds and separates the waste. The drain field is where that wastewater gets filtered and absorbed into the ground safely.
When the drain field fails, the water has nowhere to go. That’s when the smells, backups, wet spots, and even health risks start showing up. The drain field may not be flashy, but it’s one of the most important parts of your whole system.
3. What Are the Signs Your Drain Field Might Be Failing?
Here’s what we see most often in South Texas:
Standing water in the yard, even when it hasn’t rained
Soggy patches or muddy areas around the septic system
Sewage smells coming from the yard
Slow drains throughout the house
Toilet backups even after pumping the tank
Bright green grass over the drain field (sounds good—but it’s not)
If you’re seeing these, don’t ignore them. A failing drain field doesn’t fix itself, and delaying repairs can lead to bigger problems—fast.
4. How Much Does Drain Field Replacement Cost Near Nueces County?
This is the big question—and the answer depends on several things. But here’s what we typically see:
In South Texas, drain field replacement costs range from $5,000 to $15,000+.
Here’s a breakdown:
These prices include removing the old drain field, trenching, installing the new lines or chambers, backfilling, and inspections.
5. What Can Make the Price Go Up—or Down?
Several things can affect your final price:
Soil Type – Sandy soil is easier to work with than clay or hardpan.
Yard Access – If we can’t get equipment in easily, it’ll take longer (and cost more).
Size of the System – More bathrooms and bedrooms = bigger drain field.
Permit Requirements – Some counties require more testing, plans, or paperwork.
Type of System – Gravity systems are cheaper than pressure or mound systems.
It’s a bit like remodeling a kitchen—no two projects are exactly alike.
6. Is It Better to Repair or Replace the Drain Field?
That depends on how bad the damage is. Here’s how we help our clients think through it:
If your drain field is less than 15 years old and the problem is localized, a repair might work. That could be anywhere from $1,000 to $4,000.
If the system has widespread failure, is over 20 years old, or keeps giving you problems even after pumping the tank, it’s often smarter—and more cost-effective in the long run—to go ahead and replace it.
Sometimes we can do partial replacements, which saves some money while solving the core issue.
7. How to Budget for a Drain Field Project Without Surprises
Nobody likes surprise expenses—especially when they involve sewage.
Here’s how to plan ahead:
Get a clear estimate upfront. Ask for line items so you understand what’s included.
Plan for the “what-ifs”—bad weather, deeper digging, rocky soil. Add 10–15% buffer.
Ask about payment options. Some contractors (like us) offer financing or stage payments.
Set aside funds for permits or inspections—they’re usually a few hundred bucks but can vary by county.
8. How to Choose the Right Drain Field Contractor in South Texas
Not every contractor knows septic systems—and not all of them are licensed to touch them.
Here’s what to look for:
Are they licensed and insured in Texas?
Do they have experience with local soil and regulations?
Can they show you previous projects—or reviews from real people?
Do they walk you through your options instead of pushing one solution?
Do they handle permits, inspections, and cleanup—or just the digging?
We tell our clients this all the time: you’re not just hiring someone to dig trenches. You’re hiring someone to make sure your home’s waste system works right—for years.

10. Frequently Asked Questions About Drain Field Costs in Texas
Q: Is it cheaper to just install a new septic tank?
Nope. If the tank’s fine, replacing it won’t fix a bad drain field. You’d be wasting money.
Q: Will homeowner’s insurance cover this?
Usually not. Septic issues are considered a maintenance item, not a sudden disaster.
Q: Can I put a new drain field in the same spot?
Sometimes, but not always. Texas law often requires it to be relocated if the soil is saturated or compacted.
Q: How long will the new drain field last?
With proper care? Easily 20–30 years. Sometimes longer.
