Can I install a septic system myself?

Most areas require licensed designers or installers and inspections. Check with the Mower County health department before planning any work yourself.

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.

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?

No. SepticTank.com connects you with an independent local septic company that serves Austin. That company designs, installs and prices the system.

New Septic Systems for Austin Properties

A new septic system is a long-term investment. Getting it right means a proper site evaluation, a design that fits your property and a permit approved before any digging starts.

Septic companies that work across Mower County can guide you through each step and handle much of the paperwork.

How septic installation works

Most projects follow the same steps. First comes a site evaluation and soil test, then a system design sized for the home and a permit application. After that the tank and drain field are installed, followed by a final inspection before the system is covered. Your installer coordinates much of this, but timelines depend on local review and weather.

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.

What the permit process involves

Most permit processes include a site and soil evaluation, a system design, plan approval and final inspection. Fees and timelines vary. Starting the process early, especially for new construction, keeps the project on schedule.

Understanding installation quotes

A complete quote should cover design, permits, excavation, the tank, the dispersal system, inspections and site restoration. Ask what is excluded, such as tree removal, electrical work for pumps or driveway repair. Compare quotes for the same system type.

Caring for a new septic system

Keep a copy of the design and as-built drawing, schedule your first pumping as recommended, and keep vehicles and structures off the tank and field. Plant only grass over the dispersal area and direct roof and yard runoff away from it. Systems with pumps or treatment units need regular service to stay under warranty.

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.

Getting ready for installation day

Clear access for equipment, mark wells, underground utilities and sprinkler lines, and plan where soil and materials will be staged. Your Austin installer will call in utility locates before digging. Expect some disturbance to the yard, which is regraded and seeded or restored as part of the job.

Common installation mistakes

The costliest mistakes are skipping the soil test, undersizing the system to save money, and building the field where water collects or where you later want a driveway or garage. Hiring an installer who does not handle permits can also delay the job or force rework after a failed inspection.

Replacing an old system in Austin

When a system near Austin 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. Mower County usually requires a permit and a final inspection. Ask for the as-built drawing once the work is done.

What Austin's soil means for a new system

The USDA soil survey rates most mapped soils near Austin 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. Austin averages about 35 inches of precipitation a year, which your designer will factor into where the system goes. About 3 months below freezing mean pipes and components must sit deep enough or be insulated, and installation is usually easiest outside winter.

Local conditions in Austin that affect septic installation

Among the mapped soils within about two miles of central Austin, the USDA soil survey rates 96% as very limited for septic absorption fields, 4% 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.

Austin averages about 35 inches of precipitation a year, and June is usually the wettest month. Average temperatures stay below freezing for about 3 months a year, with January averaging 16°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
