General Info
Map

The Wekiwa PFA Septic Upgrade Incentive Program (Wekiwa PFA SUIP) provides qualifying homeowners in the Wekiwa Priority Focus Area (PFA) up to $10,000 toward upgrading a conventional septic system to an enhanced nitrogen-reducing septic system.

Homeowners may receive the reimbursement directly or have a qualified septic installer or licensed plumber apply on their behalf.

Use the lookup tool at the top of the page to find out if a property is eligible for the program. If it is eligible, please fill out the interest form selecting Wekiwa PFA SUIP to begin the application process.

What is the Wekiwa PFA Septic Upgrade Incentive Program?

In 2016, the Florida Legislature passed the Florida Springs and Aquifer Protection Act to help protect Florida’s springs. Orange County received a grant from the Florida Department of Environmental Protection (FDEP) to improve the water quality of Wekiwa and Rock Springs, which are designated as "Outstanding Florida Springs" and federally designated as a Wild and Scenic River.

Excess levels of nitrogen, particularly nitrate from septic tanks, have been found to have a negative impact on these springs. Orange County developed the Septic Upgrade Incentive Program (SUIP) to encourage homeowners to upgrade existing conventional septic systems to enhanced systems that reduce nitrogen by at least 65%.

The Wekiwa PFA SUIP provides payments of up to $10,000 to eligible homeowners. Payments may be made to the homeowner or directly to a qualified installer.

Can anyone in Orange County apply for this grant?

No, potential applicants must meet the following eligibility requirements:

  • Your home must be located in both the Wekiwa and Rock Springs Priority Focus Area (PFA) and unincorporated Orange County.
    SUIP EXPANDED TO ALL UNINCORPORATED ORANGE COUNTY RESIDENTS As of October 2026, all unincorporated Orange County residents who meet program requirements, regardless of their wastewater service provider, are eligible to apply. Previously, this program was only available to Orange County wastewater customers.
  • Your home must be in an area where there are no plans to install sewer lines. If your home is not in the Orange County Utilities Wastewater Service Area, ask your provider to confirm in writing that there are no plans for sewer service. Submit that documentation with your application.
  • Use the SUIP Lookup Tool to check if you are eligible for the grant.
  • Only residential homeowners are eligible for the program.
  • If you'd like to be pre-screened for the program and receive additional information, enter your address and contact information into the Septic Upgrade Incentive Program Interest Form.
My conventional septic system is in good working order; do I still need to change my system?

No. You do not need to replace a working conventional septic system unless a repair or modification requires an upgrade. Upgrades to existing conventional septic systems on lots one acre or less will be required to obtain a repair or modification septic permit. Beginning March 1, 2025, FDEP and Florida Department of Health (FLDOH) will require that the system be upgraded from a conventional system to an enhanced system that reduces nitrogen by at least 65%.

Can I apply for the grant if I am replacing my septic with a similar system?

No, you must replace a conventional system with an enhanced system that reduces nitrogen by at least 65%. It must be installed by a licensed and qualified installer.

Will the grant cover the entire cost of a new septic system?

Not necessarily. The grant helps cover the difference in cost between conventional and enhanced nitrogen-reducing systems. In most cases, it will not cover the entire cost. You are responsible for any remaining costs and should discuss the total price with your installer.

If I recently replaced my septic system, can I apply for a grant?

You may qualify if the system was installed on or after November 1, 2020, and you meet all other program requirements. The replacement must be an eligible enhanced system that reduces nitrogen by at least 65%, and proper documentation must be submitted.

BMAP SUIP Information

General Info
Map

The BMAP SUIP provides financial assistance to eligible homeowners in Basin Management Action Plan (BMAP), Alternative Restoration Plan (ARP), and Pollution Reduction Plan (PRP) areas. Funding helps homeowners upgrade their conventional septic tank to an enhanced nitrogen-reducing septic system.

Funds are limited and available on a first-come first served basis. Homeowners may apply to receive the reimbursement, or have a qualified installer apply on the homeowner’s behalf and receive the reimbursement directly from the County.

Use the lookup tool to find out if a property is eligible for the program. If it is eligible, please fill out the interest form selecting BMAP SUIP to begin the application process.

What is the BMAP Septic Upgrade Incentive Program?

The goal of the program is to improve the health of water bodies in Orange County that are not meeting water quality standards set by the Florida Department of Environmental Protection (FDEP). A major source of water pollution in Florida is nitrogen-rich wastewater from conventional septic tanks. Wastewater can travel to nearby bodies of water and fuel algal blooms.

Orange County developed the Septic Upgrade Incentive Program (SUIP) to encourage homeowners to upgrade existing conventional septic systems to enhanced systems that reduce nitrogen by at least 65%.

The BMAP SUIP provides financial reimbursements to homeowners. Payments may be made to the homeowner or directly to a qualified installer. This program is funded by the FDEP Water Quality Improvement Grant Program.

Can anyone in Orange County apply for this grant?

No, potential applicants must meet the following eligibility requirements:

  • Your home must be located in unincorporated Orange County in one of the following areas:
    • Basin Management Action Plan (BMAP) area excluding the Wekiwa Spring and Rock Springs Priority Focus Area (PFA)
    • Alternative Restoration Plan (ARP) area
    • Pollution Reduction Plan (PRP) area
  • Your home must be in an area where there are no plans to install sewer lines. If your home is not in the Orange County Utilities Wastewater Service Area, have your provider confirm there are no plans for sewer in writing and provide that documentation with your application.
  • Use the SUIP Lookup Tool to check if you are eligible for the grant.
  • Only residential homeowners are eligible for the program.
  • If you'd like to be pre-screened for the program and receive additional information, enter your address and contact information into the Septic Upgrade Incentive Program Interest Form and select BMAP SUIP.
My conventional septic system is in good working order; do I still need to change my system?

No. The BMAP SUIP is a voluntary program that encourages eligible homeowners to upgrade to enhanced nitrogen-reducing septic systems.

At this time, only property owners with homes in the Wekiwa PFA are required to upgrade broken or defective conventional septic tanks to enhanced nitrogen-reducing systems.

Can I apply for the grant if I am replacing my septic with a similar system?

No, you must replace a conventional system with an enhanced system that reduces nitrogen by at least 65%. It must be installed by a licensed and qualified installer.

Will the grant cover the entire cost of a new septic system?

The goal of the grant is to assist with the difference in cost between conventional and enhanced nitrogen-reducing systems. In most cases, it will not cover the entire cost. You will need to negotiate the cost with your installer.

If I recently replaced my septic system, can I apply for a grant?

If you meet all the eligibility requirements and replaced your conventional system with an enhanced nitrogen-reducing system you may apply. The system must have been installed on or after July 1, 2024, and proper documentation must be submitted.

Preventing Nitrogen Pollution from Septic Tank Systems

While conventional septic systems, also known as Onsite Sewage Treatment and Disposal Systems (OSTDS), are good at removing many pollutants from wastewater, they are not designed to remove nitrogen.

Nitrogen-laden wastewater from conventional septic systems can travel into our local water bodies. As a result, these water bodies may have increased concentrations of nitrogen. Algae blooms fueled by excess nitrogen are unsightly, foul smelling, and may produce toxins that are harmful to pets, wildlife and humans.


Basin Management Action Plans

Orange County is a stakeholder in the following Basin Management Action Plans (BMAPs). Click the links to learn more about how BMAPs provide a plan to improve water quality:

New Requirements

State law changed septic and sewer requirements in some areas of Florida. The rules that apply to your property depend on its location, lot size and whether sewer service is available.

House Bill 1379 was signed into law in 2023 and passed more stringent requirements for septic systems and wastewater treatment within Basin Management Action Plan (BMAP), Pollution Reduction Plan (PRP), and Reasonable Assurance Plan (RAP) areas. New requirements include the following:

  • For new developments within a BMAP, PRP, or RAP area, lots of one acre or less will be required to connect to central sewer, if available, or use an enhanced nitrogen-reducing septic system.
  • For existing systems that are fully functional and have no current permits pending, there is no requirement to upgrade or connect to sewer.
  • Except for rural areas of opportunity, local governments are required to assess the feasibility of providing sanitary sewer for developments of more than 50 lots, on a 10-year planning horizon.

More info can be found on the Florida Department of Environmental Protection’s House Bill 1379 Fact Sheet and Frequently Asked Questions.

ORANGE COUNTY WASTEWATER ORDINANCE UPDATES

The existing Wekiwa and Rock Springs Basin Management Action Plan (Wekiwa BMAP) requires that, within the Priority Focus Area (PFA), lots one acre or less with conventional septic systems connect to sewer or upgrade to enhanced nitrogen-reducing septic systems.

Orange County now requires the following within the Orange County Priority Vulnerability Areas (PVAs) identified in the Groundwater Vulnerability Study:

  • Increased sewer connection requirements
  • New septic systems in these areas on lots one acre or less be enhanced minimum 65% nitrogen reduction systems
  • Any variances for 150’ setback from water bodies require enhanced minimum 65% nitrogen reducing systems
