Septic Installation in San Patricio County, Texas: What Homeowners Need to Know
You are likely reading this because your home is not on city sewer, your old system is failing, or you are building on land that needs a new septic system. You want the job done right. You want straight answers. You do not want a messy yard, surprise fees, or a system that fails six months later. We hear this every week from families across San Patricio County.
At B5 General Contracting, we design and install septic systems that match the way you live and the soil you live on. We are not here to brag. We are here to help you understand the process so you can make smart decisions, avoid common pitfalls, and feel confident from the first site visit through final inspection.

How a Septic System Works
A standard septic system has four main parts.
The pipe that carries wastewater from your house.
The tank that holds and separates solids and liquids.
The treatment area where liquids are filtered by soil or by an aerobic unit.
The final dispersal area that returns treated water to the ground.
Inside the tank, heavy solids sink and form sludge. Lighter materials float and form scum. Liquid in the middle flows out to the drain field or into a treatment unit. Good design and regular pumping protect the system and your yard. When the design is wrong or the tank is not maintained, you get odors, backups, and soggy patches. That is what we want to avoid.
Septic vs. Sewer in San Patricio County: Which Makes Sense for Your Property?
If your property sits along a city line with available sewer service, a tap may be an option. For many homes in San Patricio County, sewer is not nearby or the hook-up cost is high. A well designed septic system becomes the practical choice. It gives you independence and can last decades with basic care. For new builds and rural homes, septic is often the most cost effective path from day one.
Local Permits and Rules for Septic Installation in San Patricio County, TX
In Texas, onsite wastewater systems are regulated. That means your system must meet local and state standards. A licensed site evaluator or engineer studies your soil and layout. Your installer follows the approved plan. Inspections confirm the system is built to code before you cover the ground. This is a good thing. It protects your home value and the local groundwater.
We help you through permits, plan review, and inspection steps, and we speak the same language as the county office. You do not have to juggle forms or guess what comes next. We keep a clear checklist and timeline so you know where you are in the process.
Soil Tests and Site Evaluations: Why South Texas Conditions Matter
Soil in our coastal region can change a lot within a few hundred feet. Some lots have sandy loam that drains well. Others have heavy clay that holds water after a storm. A site evaluation tells us how fast water moves through your soil, how high the seasonal water table sits, and where we can safely place the system.
This test guides everything. It affects the type of system you need, the size of the drain field, the depth of trenches, and the cost. Skipping this step or cutting corners is the fastest way to a failed system. We do not install blind. We test, measure, and design for your soil.
Choosing Your System Type: Conventional vs. Aerobic
Most homes in our area use one of two systems.
Conventional systems use a tank and a soil based drain field. They work best in soils that drain at a moderate rate. They have few moving parts and simple maintenance.
Aerobic treatment units add air to help bacteria break down wastewater. The treated water is often dispersed by spray or drip. Aerobic systems fit sites with slower soils, higher water tables, or small lots. They need electrical power and routine service.
We recommend the type based on your soil test, your lot size, set-back rules, and your budget. There is no one-size system. The best system is the one that fits your land.
Concrete, Plastic, or Fiberglass Tanks: Pros, Cons, and Lifespan in Coastal Texas
Concrete tanks are durable and resist buoyancy in high water table areas. They are heavy and stable. They can crack if installed poorly, but a solid install lasts a long time.
Plastic tanks are light and resist corrosion. They install faster but need proper anchoring in areas with shallow groundwater or flood risk.
Fiberglass tanks are strong and do not rust. They also need correct bedding and anchoring to prevent shifting.
We choose the tank material based on soil, access, and water table conditions. Long life has more to do with correct install, good bedding, and proper backfill than with the material alone.
Septic System Sizing and Design: Bedrooms, Daily Flow, and Setbacks
System size depends on the number of bedrooms and expected daily water use. Bigger households need larger tanks and more drain field area. Setbacks also matter. Your system must be a safe distance from wells, property lines, buildings, and water bodies. Good design balances all of this. We map the lot, mark the setbacks, and route lines to avoid trees, roots, and future building plans. If you want to add a shop or pool one day, tell us now. We can protect that space.
Septic Installation Cost in San Patricio County: What Drives the Price
Several factors set the price.
System type and size.
Soil conditions and water table.
Distance from the house to the system.
Access for equipment.
Electrical work for aerobic units.
Pumps or alarms if required.
Permit and inspection fees.
We provide itemized bids so you can see where the money goes. We also explain options that can lower costs without lowering quality, like routing changes or tank material choices that still meet code and performance goals.
Timeline: From Quote to Final Inspection
Most projects follow a simple path.

Site visit, soil test, measurements, and design notes. We confirm the scope and give you a clear estimate.
Week 2
Permitting and plan approval. This can be faster or slower depending on the office workload. We keep you updated.
Week 3
Install. We schedule equipment, order tanks and materials, and begin excavation. A standard install takes one to three days, weather and inspections permitting.

Layout and marking
We mark tank, lines, and setbacks. You see where everything will go.Excavation and bedding
We dig to the correct depth and set a stable base. This is critical. Good bedding protects the tank and lines for years.Tank placement
We set the tank level and verify inlet and outlet height. We check for proper fall from the house.Piping and fittings
We use quality pipe and tight fittings. We install risers to grade so you can access the tank lids for pumping.Drain field or treatment unit
We install trenches, chambers, or drip lines based on the design. For aerobic units, we set the unit, air pump, and spray or drip dispersal.Electrical and alarm
If required, a licensed electrician connects power and alarms. We test the system end to end.Inspection and backfill
We schedule the inspector. After approval, we backfill in layers and grade the surface to shed rainwater away.Owner walk-through
We show you where everything is, how to care for it, and what to watch for after big rains or heavy use.
Inspections, Approvals, and Final Sign-Off in San Patricio County
The inspector checks the tank set, pipe slopes, drain field layout, and the operation of any pumps or aerators. This step protects you. We plan for it, meet the inspector on site, and address any notes right away. After approval, you keep copies of permits and as-built drawings. These help with future maintenance and any home sale.
Your First 30 Days After Install: Do’s, Don’ts, and Care Tips
Do spread out laundry and long showers. Give the system time to settle.
Do keep heavy vehicles off the drain field and tank area.
Do call us if you smell strong odors or see wet spots.
Do keep lids closed and locked.
Do teach the family what not to flush. Paper towels, wipes, and grease cause problems.
Do protect the surface with grass. Roots help hold soil without clogging lines.
Avoid big water dumps like emptying a hot tub into the system. Avoid landscaping with deep roots over the drain field. Avoid building patios, sheds, or driveways over any part of the system.
Maintenance in South Texas: Pumping Schedules, Additives, and Best Practices
Plan to pump the tank on a regular cycle. Most homes do well with pumping every three to five years. Larger families or homes with heavy kitchen use may need more frequent service. Aerobic systems need periodic service checks. We can set a reminder schedule so you do not have to keep this in your head.
You do not need miracle additives. A healthy system has the bacteria it needs. Focus on routine pumping, smart water use, and quick repairs if a part fails. That will give you the longest life for the lowest cost.
Common Septic Problems in San Patricio County and How to Prevent Them
Odors near the tank or yard often point to a vent, lid, or seal issue.
Slow drains can mean a clog between the house and tank or a full tank.
Wet spots over the drain field can signal overloading, broken lines, or poor grading.
Alarm on an aerobic unit means a power, pump, or air issue.
Prevention is simple. Pump on time. Fix leaks in the house. Spread out laundry days. Keep downspouts away from the drain field. Call for service when small issues show up. Small fixes stay small when you act early.
Red Flags When Hiring a Septic Installer (Questions to Ask Before You Sign)
Can you explain the soil test and how it affects my design
What permits are needed and who handles them
What setbacks apply to my lot
What is included in grading and yard restoration
Will I get as-built drawings and maintenance guidance
What is your plan if groundwater appears during excavation
Do you include risers to grade for easy pumping
What does your warranty cover and for how long
Be careful with bids that are vague or far below others without clear reasons. Low price can mean skipped steps, poor materials, or change orders after work begins. You deserve a clear scope, fair price, and a system that will last.
Warranties, Service Plans, and Financing Options for New Septic Systems
Ask about tank, pump, and aerator warranties. Ask what is covered by the installer and what is covered by the manufacturer. We also offer service plans for aerobic systems so you know checks and filter cleanings are handled on schedule. If you need financing, we can point you to local options that many of our customers use. Clear terms help you budget without stress.
Environmental and Floodplain Considerations Near the Coast
In low areas and near waterways, we plan for rain events and high groundwater. That can mean choosing a tank that resists buoyancy, adding anchors, raising components, or selecting drip or timed dosing so the drain field is not overloaded after storms. Good design protects both your home and the local environment. It also reduces risk of damage that can lead to costly repairs.
DIY vs. Hiring a Pro in Texas: Risks, Liability, and Long-Term Costs
You might be handy with tools, but septic work is more than digging a hole and setting a tank. It needs permits, correct elevations, watertight seals, and safe setbacks. A small error can cause sewage backups, penalties, and a full replacement. When you hire a licensed professional, you protect your property value and your health. You also get a system that passes inspection the first time.
