Common symptoms indicating replacement may be necessary include:
- Persistent backups despite pumping and repairs
- Drainfield permanently saturated due to rising water table
- System age over 20 years with multiple component failures
- Soil failure preventing proper percolation
- Repeated drainfield failures in the same location
- System no longer meets current Miami-Dade County standards

If your system shows these symptoms, replacement with a modern, compliant system may be necessary. However, if targeted repairs can restore function, see our septic system repair service in Kendall for information about repair options.
What is different about drainfield replacement in Kendall
A tank and drainfield replacement in Kendall is a new system under Ordinance 22-83: DERM approval, an engineered design, an advanced treatment unit and a drain field bottom at least 36 inches above the wet-season high water table. With about 64% of unincorporated residential septic parcels within 42 inches of peak groundwater in the County's 2018 study, many Kendall replacements need a raised field.
Kendall's lakes and canals matter for layout, because the system must stay at least 100 feet from any surface water body. On lake-front lots that can push the field toward the street side of the house.
Kendall is unincorporated, so check sewer on the County's iWASD Connect map first; where a line abuts the lot, the County does not allow the replacement.

Frequently Asked Questions
How much does septic tank and drainfield replacement cost in Kendall?
Replacement costs vary significantly based on system type, size, and site conditions. Advanced treatment systems required by Miami-Dade County regulations typically cost significantly more than conventional systems. Standard residential replacements typically range from $15,000 to $30,000 or more, depending on system requirements. We provide detailed estimates during your consultation.
How long does the replacement process take in Kendall?
Total timeline from initial assessment to completed installation typically ranges from 4-8 weeks. This includes permitting (several weeks for DERM approval), installation (1-3 weeks), and post-installation inspection. Complex projects or permit delays can extend this timeframe.
What type of system will I need for replacement in Kendall?
Miami-Dade County prohibits Type 1 conventional systems for replacements. You will need a Type 2 (secondary treatment), Type 3 (advanced secondary treatment), or Type 4 (Florida Keys Nutrient Reduction) system depending on your property type, wastewater volume, and proximity to surface water bodies.
Do I need permits for replacement in Kendall?
Yes, prior written approval from the DERM Director is mandatory before any replacement system installation. The permitting process requires soil evaluation, site plan, system design, and post-installation inspection. We handle all necessary permits and coordinate with DERM.
What is the 50% reserve drainfield area requirement?
Miami-Dade County requires a reserve drainfield area equal to half the size of the initial drainfield. This reserve area is set aside for future system expansion or replacement, ensuring adequate space for system maintenance and upgrades.
Can I finance my replacement system in Kendall?
Financing options vary, and we can discuss payment plans during your consultation. Some homeowners may qualify for assistance programs through Miami-Dade County or state programs. Contact DERM directly for information about available grants, loans, or assistance programs.
Kendall questions
Does a lake-front Kendall home have trouble placing a drain field?
It can. The system and its reserved area must be at least 100 feet from the lake or canal, which on many lots leaves only the front yard.
Can a Kendall replacement stay where the old drain field was?
Sometimes, if the spot still meets the 100-foot setback from lakes and canals and the 36-inch separation from the wet-season water table. Older Kendall fields were built to a 12-inch separation, so the new one often sits higher.
