Utility Connection Requirements for Florida Projects

Whether you’re developing a single commercial lot or a large residential community, every project in Florida must connect to essential utilities — water, wastewater, and sometimes reclaimed water.

The process may seem straightforward, but utility design and permitting are among the most detailed aspects of civil engineering. Each jurisdiction has unique requirements, and coordination between agencies is crucial for timely project approval.

Why Utility Coordination Matters

Florida’s water and wastewater systems are managed by a mix of city, county, and regional authorities.
A well-prepared utility design package ensures:

• Proper capacity allocation for domestic and fire demand.

• Compliance with Florida Department of Environmental Protection (FDEP) rules.

• Smooth review by public works or utilities departments.

• Reduced risk of costly redesigns during construction.

Typical Utility Connection Requirements

Utility Type	Requirement	Key Submittal Items
Potable Water	Must connect to public water system where available.	Service line plan, meter sizing, pressure data, and backflow prevention detail.
Sanitary Sewer	Gravity or force main connection to municipal system.	Flow calculations, rim/invert elevations, lift station design if needed.
Fire Service	Dedicated line and backflow preventer per NFPA 24.	Hydrant layout, fire flow test, and coordination with Fire Marshal.
Reclaimed Water (if available)	Used for irrigation to reduce potable water demand.	Meter and line layout, cross-connection control plan.
Private Wells/Septic	Allowed only where public systems are unavailable and permitted by FDEP/DOH.	Separation distances and soil testing documentation.

Steps to Obtain Utility Connection Approval

1. Confirm Utility Provider Jurisdiction

   • Verify whether the site is served by city, county, or private utility authority.

   • Common providers include Miami-Dade Water & Sewer, Broward County Utilities, or private entities like Florida Public Utilities.

2. Submit a Utility Availability Request

   • Obtain a formal letter confirming connection feasibility and available capacity.

3. Prepare Engineering Plans

   • Include utility layout, profiles, hydrant spacing, and pipe slopes.

   • All plans must be digitally signed and sealed by a Florida PE.

4. Perform Fire Flow Test

   • Required before final water system design.

   • Coordinate with the local fire department to verify residual pressure.

5. Submit for Review and Permitting

   • Upload to the jurisdiction’s permitting portal along with fees and submittal forms.

6. Construction & Inspection

   • All installations inspected by the utility authority before activation.

FDEP Permitting Requirements

The Florida Department of Environmental Protection (FDEP) regulates all public water and wastewater systems under Rule 62-555 and 62-600, F.A.C.
Any new or modified system must receive:

• Construction permit (Form 62-555.900(1))

• Clearance to operate (Form 62-555.900(11))

Common Utility Design Issues

• Incorrect separation between water and sewer lines (must be 10 ft horizontally).

• Missing backflow preventer details on water connections.

• Unverified connection elevations causing sewer conflicts.

• Fire flow calculations not matching hydrant spacing plan.

• Using outdated standard details not matching current utility standards.

A pre-submittal meeting with the utility provider can prevent these issues before final design.

Coordination with Local Standards

Every municipality has its own Utility Design Standards Manual — for example:

• Miami-Dade Water and Sewer Department (WASD) Design Standards

• Broward County Water and Wastewater Services

• Palm Beach County Utilities Department

These documents specify pipe materials, pressure ratings, trench sections, and testing procedures.

Conclusion

Utility connections form the backbone of every development project in Florida. Proper coordination between engineers, contractors, and utility providers ensures timely permitting, safe operation, and long-term reliability.

FAQs

• Who provides the utility availability letter?

  The local or regional utility provider for your project’s service area.

• What separation is required between water and sewer lines?

  10 feet horizontal, 18 inches vertical (per FDEP Rule 62-555).

• Is a fire flow test mandatory?

  Yes — for any project with new fire hydrant or service line installation.

• How long does utility review take?

  Typically 30–60 days depending on jurisdiction.
