How long does septic installation take?

Installation itself often takes a few days to two weeks. Soil testing, design and permit review can add several weeks, so plan ahead.

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.

Who approves septic installations in Cheyenne?

Septic permits are usually handled at the county or state level. Contact the Laramie County health department to confirm the requirements for your property.

New Septic Systems for Cheyenne 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 Laramie County can guide you through each step and handle much of the paperwork.

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.

Septic system types and when they fit

A conventional gravity system works where soil drains well and there is room for a field. Where soil is shallow, wet or slow, designers turn to pressure distribution, mound systems, chamber systems, drip dispersal or aerobic treatment units. The soil test, not preference, usually decides which one a lot needs.

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.

Why installation prices vary

Installation price depends on the system type the soil allows, the size of the house, the distance from the house to the field, how easy the site is to reach with equipment, and design and permit fees. Engineered systems such as mounds and aerobic units cost more to build and maintain.

The first years with a new system

Keep the design drawing and the final inspection report somewhere safe. Pump on the schedule your installer recommends, use water steadily rather than all at once, and keep vehicles and new structures off the tank and field. Let grass establish over the field before heavy use of the yard.

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 the whole project takes

The digging and installation often take days, but the full project in Cheyenne can take several weeks once testing, design and permit review are included. Ask your installer for a realistic timeline for your county and what could change it, such as wet weather or a busy review office.

Questions that prevent problems later

Before work begins in Cheyenne, 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.

New septic systems in Laramie County

New and replacement systems in Laramie County go through the Laramie County health department, which reviews designs and inspects the work. Soil conditions change from one part of the county to another, so a design that suits a lot in Cheyenne may differ from one in nearby communities. A local installer knows those differences.

What Cheyenne's soil means for a new system

Soils around Cheyenne range from good to very limited, so the system type depends on the results of the soil test on your lot. Cheyenne gets about 17 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 Cheyenne that affect septic installation

Among the mapped soils within about two miles of central Cheyenne, the USDA soil survey rates 39% as very limited for septic absorption fields, 51% as somewhat limited and 10% as not limited. The most common drainage class is well drained. Conditions vary from lot to lot here, so a site evaluation is the only way to know how well a particular yard will handle a drain field.

Cheyenne averages about 17 inches of precipitation a year, and May is usually the wettest month. Average temperatures stay below freezing for about 3 months a year, with December averaging 26°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.

What the soil around Cheyenne means for septic installation

By drainage class, the USDA soil survey maps the land around Cheyenne as 85% well drained, 15% poorly 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.
