Septic Tank Installation & Replacement in West Palm Beach, FL
New construction or an aging tank that's due for replacement, done to code. We connect you with a licensed local pro who handles the whole process.
What Septic Tank Installation Actually Involves
A new septic system starts with a site evaluation, not a tank order. Soil type, water table depth, and household size all determine what size and type of system a property actually needs.
Real tank brands and materials matter here. Manufacturers like Infiltrator and Xerxes produce the tanks referenced in Florida DEP approval documentation, and the material and construction standards a tank has to meet are set by state code.
Every new system requires a county permit before installation, and a final inspection before it's approved for use.
Florida law requires septic installation to be performed by a DEP-registered or Master septic contractor. This isn't a homeowner DIY project under state code.
When a New Tank Makes Sense
A tank that's failing structurally, cracked walls, a collapsing lid, or persistent leaks, generally can't be repaired back to a reliable state.
How Septic Tank Installation Works
Site Evaluation
Soil type, water table depth, and lot size all factor into the right system size and design.
System Design and Permitting
The design gets submitted for the required county permit before any digging starts.
Installation
The tank and drain field get installed to code, sized correctly for the property.
Final Inspection
The completed system gets inspected and signed off before it's put into use.
Why Installation Design Matters Here
Palm Beach County's high water table means the site evaluation step carries more weight here than in areas with more stable, absorbent soil. A system sized for average conditions elsewhere can fail early if it isn't designed for local conditions specifically.
This area sits within the Lake Worth Lagoon watershed, home to roughly 22,000 documented septic systems and the subject of an active county water-quality effort backed by more than $100 million in bond funding aimed at reducing nutrient loading into the lagoon. New or replacement systems in this watershed may be required to install an ENR-OSTDS, an enhanced nutrient-reducing system, rather than a conventional tank, specifically because of this nutrient-impaired designation. A site evaluation determines whether your property falls under this requirement.
What Septic Tank Installation Typically Costs
A conventional gravity system typically runs $5,000 to $9,000. If your site evaluation calls for an ATU, costs run higher, generally $15,000 to $35,000 or more, and an ENR-OSTDS requirement, relevant to properties in the Lake Worth Lagoon watershed, adds roughly $8,000 to $20,000 on top of a base install. Sites that need a mound system due to a high water table run higher still, see our Drain Field Replacement / Mound Systems page for that pricing.
Beyond the tank itself, expect $500 to $2,000 for the required perc test and site evaluation, and $250 to $1,000 for the county permit.
One ongoing cost worth planning for upfront: an ENR system requires an annual maintenance contract running $800 to $1,500 a year, compared to $300 to $500 a year for a conventional system.
These are typical ranges, not a quote. Your actual cost depends on system type, site conditions, and whether nutrient-reduction requirements apply to your property.
Example Job — New Construction, West Palm Beach
Enhanced nutrient-reducing system installed and permitted for a new home within the watershed boundary
The Problem
A homeowner building a new house within the Lake Worth Lagoon watershed, not connected to city sewer, needed a septic system designed and permitted before construction could move forward.
The Diagnosis
A site evaluation confirmed the property fell within the nutrient-impaired watershed's designated boundary, meaning an ENR-OSTDS was required rather than a conventional system, on top of the area's typical high water table and sandy soil conditions.
The Fix
The connected contractor designed an ENR-OSTDS sized for the home's bedroom count, submitted the design for county permitting, and installed the system to the approved plan. A final inspection signed off before the county issued a certificate of occupancy.
Recurrence Prevention
The homeowner was set up with the required annual ENR maintenance contract from day one, since it's not optional under the watershed's nutrient-reduction requirements.
| Item | Cost |
|---|---|
| Site evaluation / perc test | $500–$2,000 |
| County permit | $250–$1,000 |
| ENR-OSTDS installation | $13,000–$29,000 |
| Total | $13,750–$32,000 |
Costs vary by system type, site conditions, and local permitting fees — this reflects a typical new-construction ENR-OSTDS required by the Lake Worth Lagoon watershed designation and is not a quote. A free estimate from your connected professional will confirm exact pricing for your property.
