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.

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.

Who approves septic installations in St. Paul?

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

Septic System Installation in St. Paul, MN

Whether you are building a new home in St. Paul or replacing a system that has reached the end of its life, septic installation is a project that starts with the soil. The right system depends on your lot, your soil and the size of your household.

Request a call and a local septic company that installs systems in St. Paul and West St. Paul, Falcon Heights, Mendota Heights will explain the process from site evaluation to final inspection.

The installation process step by step

It starts with testing the soil to see how well it absorbs water. A designer or engineer then sizes the tank and dispersal area for the number of bedrooms. After the permit is approved, the crew excavates, sets the tank, installs the pipes and field, and schedules an inspection before backfilling.

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 St. Paul, the soil on your specific lot is what decides which category you fall into.

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.

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.

Before you sign

Make sure the contract lists the system type, the scope of work, permit responsibilities, the timeline, cleanup and warranty. Ask how weather or unexpected site conditions will be handled.

How long a new system takes near St. Paul

Soil testing, design and permit review usually take longer than construction. In Ramsey 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 St. Paul, 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 St. Paul

A new septic system near St. Paul 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. Ramsey 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 St. Paul's soil means for a new system

The USDA soil survey rates most mapped soils near St. Paul 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. St. Paul averages about 33 inches of precipitation a year, which your designer will factor into where the system goes. About 4 months below freezing mean pipes and components must sit deep enough or be insulated, and installation is usually easiest outside winter.

Local conditions in St. Paul that affect septic installation

Among the mapped soils within about two miles of central St. Paul, the USDA soil survey rates 100% as very limited for septic absorption fields, 0% 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.

St. Paul averages about 33 inches of precipitation a year, and June is usually the wettest month. Average temperatures stay below freezing for about 4 months a year, with January averaging 13°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
