Septic Tank Installation FAQs
What is septic tank installation?
Septic tank installation is the process of excavating and placing an underground tank and drain field system that collects, treats, and disperses wastewater from your home or building. It’s the primary alternative to connecting to a municipal sewer system.
Do I need a septic system if I'm not connected to city sewer?
Yes. Any home or structure that generates wastewater and isn’t connected to a municipal sewer line is required by law to have an approved septic system. Without one, you’re not only out of compliance — you’re creating a serious health and environmental hazard.
How long does septic tank installation take?
Most residential septic installations take one to three days for the excavation and installation phase, though the full timeline including permitting, inspections, and site restoration can take one to two weeks. We’ll give you a clear schedule during your free estimate.
What permits are required for septic installation in Idaho?
Septic installations in Idaho require permits through your local county health district. Requirements vary by county and soil type, and inspections are required at key stages of the installation. As a licensed Complex Septic Installer, we handle this process on your behalf.
What is a percolation test and do I need one?
A percolation test, or perc test, measures how quickly your soil absorbs water. This determines what type of septic system is appropriate for your property and where the drain field can be located. Most new installations require one before permits can be issued.
How do I know where my septic system should be located?
Placement is determined by a combination of factors including setback requirements from wells, property lines, and structures, as well as soil conditions and the natural slope of your land. A licensed engineer or soil scientist typically designs the system layout based on these factors.
What size septic tank do I need?
Tank size is determined by the number of bedrooms in your home and your estimated daily water usage. In Idaho, most single-family homes require a minimum 1,000 gallon tank, though larger homes or properties with higher usage may need more capacity. Your engineer’s design will specify the correct size.
What is a drain field and why does it matter?
A drain field, also called a leach field, is a network of perforated pipes buried in gravel trenches that disperses treated wastewater into the soil. It’s a critical part of the system — without a properly designed and installed drain field, even a perfect tank installation will fail.
Can you replace an old or failing septic system?
Yes. We handle full system replacements including excavation and removal of the old system, proper abandonment procedures, and installation of a new code-compliant system. If your system is backing up, surfacing, or failing inspections, contact us to evaluate your options.
How deep is a septic tank buried?
Most septic tanks are buried with the top of the tank between 4 inches and 4 feet below the surface, depending on your property’s grade and the system design. Risers are often installed to bring access lids closer to the surface for easier maintenance.
Will installation damage my yard or landscaping?
Some disruption is unavoidable, but we work efficiently and restore the site as thoroughly as possible after installation. We backfill and grade the disturbed area and will walk you through what to expect before we start so there are no surprises.
How do I maintain my septic system after installation?
Regular pumping every three to five years is the most important maintenance step. You should also avoid flushing non-biodegradable items, limit use of harsh chemical cleaners, and keep heavy vehicles and deep-rooted plants away from the drain field area.
What is the difference between a conventional and alternative septic system?
A conventional system uses gravity to move wastewater from the tank to a standard gravel drain field. An alternative system uses pumps, specialized media, or engineered drain fields to treat wastewater in situations where soil conditions or lot size don’t support a conventional design. The right choice depends on your property’s specific conditions.
Can you install a septic system on a small or difficult lot?
Often yes. Alternative and engineered system designs have expanded what’s possible on challenging properties. We’ve worked on a wide range of lot sizes and conditions throughout the Treasure Valley and can help determine what options are available for your specific situation.
What does septic tank installation cost in Boise?
Cost varies based on system type, tank size, drain field design, soil conditions, and site access. A conventional system on a straightforward lot will cost less than an engineered alternative system on a difficult property.
