New Septic Systems for Lewisville Properties
Replacing a failed system or installing one for a new build in Lewisville 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.
From soil test to finished system
A septic installation starts with a soil and site evaluation, which decides what kind of system the lot can support. A designer then sizes the system for the number of bedrooms, the plan goes to the Forsyth County health department for a permit, and the installer digs, sets the tank and builds the drain field before a final inspection.
Types of septic systems
Conventional systems use a tank and a gravity drain field and suit lots with good soil. Where soil is poor, shallow or wet, options include pressure distribution, mound systems, chamber systems, sand filters and aerobic treatment units. Your soil test and local rules decide which types are allowed on your lot.
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.
Why installation prices vary
Soil and site conditions drive most of the difference. A flat lot with deep, well-drained soil is simpler than a sloped lot with clay or high groundwater. Access for equipment and the distance from the house also matter.
Getting the most from your new system
Good habits protect your investment: spread out laundry, fix leaks promptly, avoid flushing wipes and grease, and pump on schedule. If your system has an alarm, learn what it means and who to call.
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 Lewisville
Soil testing, design and permit review usually take longer than construction. In Forsyth County, 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 Lewisville 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 Lewisville installer to walk you through the site plan and explain why each part sits where it does.
Before the digging starts in Lewisville
Installing a septic system in Lewisville touches the whole yard, so plan access for the excavator and the tank delivery. Mark wells, water lines and property corners first. Ask the installer how they will restore the lawn afterward. A clear plan now avoids moving a driveway, a shed or a fence later.
What Lewisville's soil means for a new system
The USDA soil survey rates most mapped soils near Lewisville 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 47 inches of precipitation a year, designers here account for high water tables and runoff when sizing and placing a system.
Local conditions in Lewisville that affect septic installation
Among the mapped soils within about two miles of central Lewisville, the USDA soil survey rates 70% as very limited for septic absorption fields, 30% as somewhat limited and 0% as not limited. The most common drainage class is well drained. Soils like these often call for careful system design, such as a larger drain field, a mound or another engineered system, and a site evaluation before any new installation or replacement.
Lewisville averages about 47 inches of precipitation a year, and July is usually the wettest month. January is the coldest month at about 37°F on average, so freezing is rarely the main concern here. Heavy rain and saturated ground are the bigger factors for drain fields.

- Do I need a soil test for a new septic system?
- Yes, in nearly all cases. The soil evaluation decides what type of system and how large a field your lot can support.
- Is SepticTank.com the installer?
