Before you get quotes
This is county-permitted work, almost always.
A licensed contractor normally files for you, but the county — not the contractor — decides what your lot can support. Budget the permit step into your timeline, not just the install.
As of 2026-09, a complete septic tank and drain-field replacement in California typically costs $6,000–$10,000, with system type — conventional, mound, aerobic, and similar — the biggest driver within that range.

Septic installation cost by system type
Nationally sourced (Angi) figures by system type, alongside the California-specific working range this site quotes for a complete Visalia-area job. Which type your property qualifies for is determined by soil and site conditions, not preference — see the permit process below.
| System type | Typical cost | Notes |
|---|---|---|
| Anaerobic (conventional gravity) | $3,000–$8,000 | The standard system on suitable soil — usually the lowest-cost option |
| Chamber | $5,000–$12,000 | A common alternative to gravel-and-pipe drain fields |
| Sand filter | $7,000–$18,000 | Used where soil alone can’t adequately treat effluent |
| Aerobic treatment unit | $10,000–$20,000 | Adds mechanical aeration; higher cost, smaller footprint |
| Mound system | $10,000–$20,000 | Used on shallow soil, high groundwater, or bedrock-limited lots |
| Complete tank + drain field (California working range) | $6,000–$10,000 | California The working range this site quotes for a full Visalia-area tank-and-drain-field replacement — closer to real California labor and permit costs than the national figure. |
National overall average: $3,593–$12,463 (Angi, national — average $8,017 (read Aug 2026)). Full sourcing, tank-material breakdown, and permit/excavation line items: our septic cost guide.
The county permit process
- 1
A licensed contractor assesses the site
Soil type, lot size, groundwater depth, and setback distances from wells, property lines, and structures all affect what kind of system a property can support.
- 2
A percolation test confirms the soil can absorb effluent
This test, run by or coordinated with the contractor, measures how quickly water drains through the soil at the proposed drain-field site — it drives the system design, not just a formality.
- 3
The design goes to Tulare County RMA / Environmental Health for review
Most septic construction and repair work in Tulare County needs a permit through the Resource Management Agency / Environmental Health Division, (559) 624-7400. Hanford-area properties fall under Kings County instead.
- 4
The county issues the permit (or asks for design changes first)
Timelines and fees for this step are not published by the county in a way we can confirm from here — call the number above for a job-specific answer rather than assuming a figure from another county or state.
- 5
The licensed contractor installs the system
Once permitted, the CSLB C-42 contractor does the excavation, tank placement, and drain-field construction according to the approved design.
- 6
A final county inspection signs off before backfill is complete
The county typically inspects before the system is fully covered, to confirm it was built to the approved design.
Most septic construction and repair work in Tulare County requires a county permit through the Tulare County Resource Management Agency / Environmental Health Division, (559) 624-7400. Hanford-area properties fall under Kings County instead.
What drives the cost besides system type
- Tank material — concrete ($2,500–$5,000), fiberglass ($1,500–$2,000), or plastic ($1,000–$2,000), plus $1,000–$5,000 labor, per California-specific figures.
- Excavation — $1,500–$6,300 nationally, driven by soil type, access, and how much material has to move.
- Percolation testing — $700–$2,000, consistent across two independent national sources.
- Land survey — $330–$900, sometimes required to confirm setbacks and lot boundaries.
- Permits — national sources disagree meaningfully ($450–$2,300 vs. $250–$650); Two national sources disagree meaningfully on permit cost — shown as a range of ranges rather than averaged away. Tulare County’s own fee schedule is not published (VIS-003); call (559) 624-7400 for the actual local figure.
- Drain field installation — $5,000–$12,000, on top of the tank itself.
- System upgrades — basic enhancements over a standard system run $3,000–$5,000; advanced technology systems (aerobic, mound) commonly exceed $10,000.
California's $1,000 statewide minor-work exemption (AB 2622) essentially never applies to real septic installation or replacement — the exemption requires no permit be needed and the job value to stay at or under that figure, and septic installation routinely fails both conditions. Don't expect it to reduce what licensing applies to your job.
New construction vs. replacing a failed system
A new-construction install on a rural parcel and a replacement for a failed existing system go through the same county permit process, but they start from different points. New construction usually has a clean slate to design around, while a replacement has to work around the home's existing footprint, driveway, and any other underground utilities already in place — which can affect where a compliant drain field will actually fit. If your existing system has failed rather than simply aged out, get a clear answer from your contractor on whether repair is still realistic before committing to a full replacement — see our septic repair & emergency backup guide for the general repair-vs-replace pattern.
FAQ
Installation & replacement questions Visalia homeowners ask
How much does a new septic system cost near Visalia, CA?
A complete tank-and-drain-field replacement in California typically runs $6,000–$10,000, closer to real local labor and permit costs than the wider national range of $3,593–$12,463. The system type your lot can support — conventional, mound, aerobic, and so on — is the biggest driver of where in that range a specific job lands.
Do I need a permit to install or replace a septic system in Tulare County?
Yes — most septic construction and repair work in Tulare County requires a permit through the Resource Management Agency / Environmental Health Division, (559) 624-7400. Hanford-area properties fall under Kings County instead. We don't publish a specific fee or timeline because the county hasn't published one we could confirm — call for a job-specific answer.
Who is licensed to install or replace a septic system in California?
A CSLB C-42 Sanitation System Contractor. Verify anyone doing this work at cslb.ca.gov before signing a contract — this is different from septic pumping, which is a separate, county-registered trade rather than a CSLB classification.
What determines which type of septic system a property can have?
Soil type and percolation rate, lot size, groundwater depth, and setback distances from wells, structures, and property lines. A percolation test run as part of the permit process is what actually determines which system types your specific lot qualifies for — not preference or budget alone.
Does the $1,000 minor-work exemption apply to septic installation?
No, in practice. California's statewide minor-work exemption (AB 2622, effective January 1, 2025) only applies when the job value is $1,000 or less, no permit is required, and the person doing the work employs no one else. Septic installation and replacement routinely requires a county permit and costs well above that threshold, so this exemption essentially never applies to real septic system work.
How long does septic system installation take?
The permit and design phase — site assessment, percolation testing, county review — often takes longer than the physical installation itself, and neither timeline is something we publish a specific figure for without a confirmed source. Ask your contractor and the county for a schedule specific to your job and current permit review volume.
