Septic System Installation Cost in 2026: New System & Tank Prices
$3,590–$12,463
Typical national range · reviewed 2026-10
A new septic system costs $3,590 to $12,463 installed, with most homeowners spending around $8,016 (HomeAdvisor, updated Jun 20, 2026), and labor is 50% to 70% of that bill. Mound and aerobic systems run $10,000 to $20,000 in the same data. The spread comes down to the system type your soil allows, the size your home needs, and your county's permit stack, so two homes on the same road can get very different quotes.

$297–$584
Typical national range · reviewed 2026-10
Septic tank pumping costs $432 on average, and most homeowners pay $297 to $584 (Angi, updated Oct 14, 2026, from 6,850 projects) — that's the price to pump out, empty, or "drain" a tank, which are all the same job. Angi lists a 1,000-gallon tank at $325–$700. A routine cleaning is usually billed as the same pump-out; a deep cleaning of a neglected tank costs more. Tank size, lid access, and how overdue you are set where your price lands within that band.

$3,000–$20,000
Typical national range · reviewed 2026-10
A mound system is a drainfield built above ground in a bed of sand, fed by a pump. A conventional system is a septic tank plus a trench or bed drainfield dug into the native soil, usually fed by gravity. EPA describes mounds as an option for shallow soil, high groundwater or shallow bedrock, which is also the list of reasons a conventional field fails a site evaluation.

$3,000–$9,500
Typical national range · reviewed 2026-10
Replacing a septic tank costs $3,000 to $9,500, according to Angi's septic repair cost guide (updated Sep 15, 2026). The tank is $600 to $4,000 of that. The rest is excavation, setting and reconnecting the tank, and $500 to $1,000 of topsoil, fill, gravel and stone to secure it in the ground. HomeAdvisor (Jun 20, 2026) gives $3,000 to $10,000, and HomeGuide (Dec 22, 2025) puts a tank replacement for a 3- or 4-bedroom home at $3,500 to $8,500.

$200–$900
Typical national range · reviewed 2026-10
A septic inspection costs $200 to $900 for most homeowners, with a national average of $550, according to Angi (updated Oct 7, 2026). The full span runs from $100 for a quick check to $1,300 for a detailed home-sale inspection on a larger system. Your price depends on the type of inspection, the tank's size and depth, and whether the lid has to be dug up, which Angi says adds $50 to $250.

Grease trap cleaning costs $115 to $1,040 per pumping, according to Greasecycle's September 2025 guide to industry pricing in North Carolina. The low end is a 20- to 30-gallon under-sink trap pumped every two to four weeks. The high end is a 5,000-gallon interceptor that hasn't been pumped in years and is out of compliance. Most restaurants fall in between.
