Home/Services/Septic Tank Installation & Replacement
Septic Tank Installation & Replacement in Bonita Springs, FL
We provide septic tank installation and replacement to Bonita Springs, FL. We plan the tank and drain field around the home, soil and groundwater conditions.
Check BSU sewer availability, the floor plan, seasonal groundwater and the permit pathway first. Tank material, treatment type and drain field design are separate decisions. Site-specific approvals determine what can be installed.
The customer requested a new septic tank because the previous one was beyond its expected service life. A new 1,000-gallon concrete septic tank was installed in its place.
Cracks found during the customer’s septic inspection showed why the old tank could no longer remain in service.
We completed the excavation and site work, removed and disposed of the old tank, and installed the same type of tank: a 1,000-gallon concrete replacement.

Confirm Size, Scope & Access
Confirm the installed capacity or approved design, property records, access points and site conditions before agreeing the scope and price.
Check Sewer Before Selecting a System
Ask Bonita Springs Utilities whether sewer is available or planned for your address. Sun Village and Lakes of Sans Souci have conversion projects. Do not assume a new tank is the right investment just because a nearby house uses septic.
Confirm Size and Approved Use
Use the floor plan, bedroom count, building area and existing approval. A roughly 1,660-square-foot, three-bedroom example falls in a 300-gallon/day Florida category with 900 gallons of minimum effective storage, before any additional design requirements.
Evaluate Groundwater and Space
Seasonal groundwater, usable soil, drainage, setbacks and the disposal footprint guide the design. An old field location is not automatic approval for replacement. A larger tank cannot correct inadequate field area.
Agree the Complete Scope
Identify retained components, excavation, old-tank abandonment, treatment equipment, field work, inspections and restoration. DOH-Lee septic approval and any City permits are separate steps. Construction starts after the required approvals.
A roughly 1,660-square-foot, three-bedroom home is a useful planning example. It is close to the September 2026 Lee County listing median, not a measured average for Bonita Springs septic homes.
Concrete
Rigid and heavy. Plan lifting access and inspect lids, seams and walls. An empty concrete tank can still be affected by high groundwater.
Fiberglass
Lightweight composite. Check shell condition and fittings; follow the approved model’s support, bedding and anchoring instructions.
Polyethylene
Molded plastic. Correct backfill, burial depth and groundwater provisions help prevent deformation or movement.
Condition, installation and maintenance determine service life. Tank shells, drain fields, pumps and controls age differently.
Tank shells, drain fields, pumps and controls can have different service lives. Material alone does not set a replacement date; condition, installation, groundwater and maintenance matter.

Florida uses the bedroom or building-area calculation that produces the higher flow. Storage gallons are not treatment gallons per day. Check the installed tank label, permit and current floor plan; a larger tank alone cannot fix an undersized field.
Conventional, raised-field, aerobic and performance-based approaches solve different constraints. Check nitrogen-reduction requirements for the parcel and permit scope. There is no single system type that fits every Bonita Springs property.
Choose the Tank Material
Concrete, fiberglass and polyethylene are shell materials, not treatment types. Check the approved model, lifting access, groundwater provisions and manufacturer installation requirements.
Septic Tank Installation & Replacement FAQs
Practical answers for Bonita Springs homes and businesses.
Can I put in a basic conventional system?
Possibly, if the parcel and approved design qualify. Check sewer availability, seasonal groundwater and any nitrogen-reduction requirement with DOH-Lee. An aerobic or performance-based approach may be needed for the actual conditions.
Is an aerobic system a tank material?
No. Aerobic describes a treatment process. Concrete, fiberglass and polyethylene describe materials.
How does replacement differ from new installation?
Replacement includes evaluating the existing system and planning which old components will be removed or retained. A new installation starts with the proposed building and site. Both need an approved design suited to the property.
