Advanced & Alternative Septic Systems in Miami-Dade
Installation, maintenance, and repair of ATU, PBTS, and nitrogen-reducing septic systems — required for many Miami-Dade properties near waterways.
Advanced septic systems — including Aerobic Treatment Units (ATUs) and Performance-Based Treatment Systems (PBTS) — use oxygen injection and additional treatment stages to produce a cleaner effluent than conventional septic tanks. These systems reduce nitrogen, bacteria, and other contaminants before wastewater reaches the drain field, providing a higher level of environmental protection.
In Miami-Dade County, DERM (Department of Environmental Resources Management) requires advanced treatment systems for properties near Biscayne Bay, canals, wellfield protection areas, and other environmentally sensitive zones. Florida law now mandates Enhanced Nutrient-Reducing systems (ENR-OSTDS) in many areas to combat nutrient pollution that harms coastal ecosystems. If you're building new, replacing a failed system, or located in a designated area, you may be required to install an ATU or PBTS.
We install, maintain, and repair all major brands of advanced treatment systems — including Clearstream, Jet, Norweco, Delta Environmental, and Bio-Microbics. Unlike conventional septic tanks, ATU and PBTS systems require ongoing maintenance contracts: typically semi-annual inspections, media replacement, blower and pump service, effluent sampling, and annual operating permit renewals through DERM. We handle all of it — so your system stays compliant and your permit stays current.

Frequently Asked Questions
Common questions about alternative septic systems (atu) in Miami-Dade.
What is the difference between an ATU and a conventional septic system?
A conventional septic system relies on gravity and natural settling to separate solids from liquids. An ATU adds an aeration chamber where a blower injects oxygen, promoting aerobic bacteria that break down waste more thoroughly. The result is cleaner effluent with significantly lower nitrogen and bacteria levels — important for protecting Miami-Dade's groundwater and Biscayne Bay.
Do ATU systems require special maintenance?
Yes. DERM requires ATU and PBTS owners to maintain an active maintenance contract with a licensed provider. Typical maintenance includes semi-annual inspections, blower and pump checks, media and filter replacement, effluent sampling, and annual operating permit renewal. We offer comprehensive maintenance packages that cover everything.
How much does an advanced septic system cost in Miami-Dade?
Advanced systems cost more than conventional septic — typically $8,000–$20,000+ depending on system type, property size, and site conditions. However, they are often required by code in environmentally sensitive areas. We provide detailed estimates and help you understand available financing options before any work begins.
