Can I install a septic system myself?

Most areas require licensed designers or installers and inspections. Check with the Twin Falls 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.

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 Hansen. That company designs, installs and prices the system.

New Septic Systems for Hansen Properties

Replacing a failed system or installing one for a new build in Hansen 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 steps of a new septic installation

Expect five stages: site and soil evaluation, system design, permit approval, construction, and inspection before the trenches are covered. Weather and permit review times affect the schedule more than the digging itself, which often takes only a few days once everything is approved.

Conventional and alternative systems

A conventional system is the simplest and usually the least expensive to maintain. Alternative systems add pumps, controls or treatment steps so they can work in difficult soil. Around Hansen, the soil on your specific lot is what decides which category you fall into.

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.

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.

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 for a septic installer

Ask who will do the soil test and design, whether they pull the permit, and which system types they recommend for your lot and why. Ask how long the project will take, what warranty they give, and whether the quote includes restoring the yard. Ask for references from recent jobs near Hansen.

How long a new system takes near Hansen

Soil testing, design and permit review usually take longer than construction. In Twin Falls 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.

Questions that prevent problems later

Before work begins in Hansen, ask where the tank and field will sit relative to your well, your neighbors and any planned projects. Ask how deep the components will be, how the yard will be restored and what records you will receive when the job is done. Clear answers now save digging up the yard later to find out.

Planning a new system near Hansen

A new septic system near Hansen starts with a site visit and a soil evaluation. Those results decide the system type, the tank size and where the drain field can go. Twin Falls County reviews the design before work begins and inspects it before it is covered. Planning early keeps the project from holding up a closing or a build.

What Hansen's soil means for a new system

The USDA soil survey rates most mapped soils near Hansen 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. Hansen gets about 15 inches of precipitation a year, so water table limits are less common, though your soil test still decides the design. 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 Hansen that affect septic installation

Among the mapped soils within about two miles of central Hansen, the USDA soil survey rates 69% as very limited for septic absorption fields, 31% 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.

Hansen averages about 15 inches of precipitation a year, and December is usually the wettest month. Average temperatures stay below freezing for about 3 months a year, with January averaging 28°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.

What the soil around Hansen means for septic installation

By drainage class, the USDA soil survey maps the land around Hansen as 100% well drained. Most of the soil here drains reasonably well, so a conventional trench field is often possible where the lot allows, but the soil test still decides.
