Septic to Sewer: What Homeowners in North Miami Beach & Miami Gardens Should Know Before Connecting

Mijael • January 20, 2026

For decades, a large share of Miami-Dade homes have treated their wastewater on site, with a septic tank and a drain field in the backyard. That is changing. Miami-Dade County has been encouraging homeowners to move from septic to the public sewer system, and its program for this is called Connect 2 Protect . Many of the homes still on septic sit in established neighborhoods of north Dade, including parts of North Miami Beach, Miami Gardens and North Miami.

If a sewer line has reached your street, or you have received a notice about it, you probably have questions: what exactly needs to happen on your property, who is responsible for each part, what happens to the old tank, and how long it all takes. This guide answers those questions in plain language, based on what we see on real conversion jobs across South Florida.

Key takeaways
  • ✔ Miami-Dade County encourages septic-to-sewer conversions through its Connect 2 Protect program; eligibility and requirements depend on your address.
  • ✔ A conversion has two sides: the public sewer in the street and the private connection from your house to it.
  • ✔ The old septic tank must be properly retired: pumped out and then removed or filled in place according to code.
  • ✔ A camera inspection of your existing drain line before the work starts helps avoid surprises and change orders.

Why Miami-Dade is moving homes off septic

South Florida is a tough place for septic systems. The water table sits close to the surface, the soil is sandy and porous, and the groundwater is closely connected to canals and Biscayne Bay. A septic system needs a layer of dry soil under the drain field to filter wastewater before it reaches groundwater. When that layer is thin, or when heavy rain and high tides push the water table up, the system has less room to do its job.

That is the main reason the county has been working to expand sewer service into neighborhoods that still rely on septic: protecting groundwater and the bay, and giving homeowners a system that is less affected by rising water. For the homeowner, the practical benefits are just as real.

Staying on septic Connected to sewer
Routine maintenance Regular pump-outs and inspections are the homeowner's job. No tank to pump and no drain field to maintain.
Heavy rain and high tides A saturated drain field can slow drains or cause backups. Wastewater leaves the property through the public system.
Yard use No building, parking or heavy equipment over the tank and field. Once the tank is retired, that area of the yard is free again.
Long-term repairs Drain field replacement can be a major expense. The private line still needs care, but there is no field to replace.
Selling the home Buyers may ask for septic inspection and pump-out records. Many buyers prefer homes already connected to sewer.

On the private side, the new line runs from the house to the sewer connection point, laid at the right depth and slope so wastewater flows freely.

Who does what in a septic-to-sewer conversion

Every conversion has a public side and a private side. The exact split depends on the project and the program that applies to your street, so always confirm the details for your specific address with the county and the Miami-Dade Water and Sewer Department (WASD). In general, though, the roles look like this:

🏛️
The county and WASD
Build and own the public sewer in the street, set the connection requirements and confirm whether your property is eligible to connect.
🏠
You, the homeowner
Decide when to connect, choose a licensed contractor for the private-side work and keep the paperwork, permits and final approvals.
🛠️
A licensed contractor
Handles the private side: the final pump-out, retiring the tank, installing the new line to the connection point and restoring the yard.

In some neighborhoods the new sewer is a traditional gravity line. In others, depending on the ground and the design of the project, the connection may involve a pressure system with a small pump on the property. Which one applies to you changes the scope of the private-side work, so it is one of the first things to find out.

How the conversion works, step by step

1
Confirm availability and requirements
Check with the county and WASD whether sewer is available at your address, what program applies and what the current requirements and timelines are. We can help you figure out what to ask.
2
Inspect your existing line
Before anything is dug up, a sewer camera inspection of the drain line under and around the house shows its condition. Old cast iron or clay pipe with cracks or roots is better fixed now, while the yard is already open.
3
Plan the route and pull permits
The new private line has to reach the connection point at the right depth and slope. The work is permitted and inspected, so the plan needs to follow code from the start.
4
Pump out and retire the septic tank
The old tank receives a final pump-out. Then it is either removed or filled in place, as required by code, so it does not become a hazard or a sinkhole later.
5
Install the new connection
The house drain is redirected to the new line, which is laid, connected to the sewer and tested before backfill.
6
Final inspection and restoration
Once the work passes inspection, the trench is backfilled and the yard is restored. Keep every document: permits, inspection approvals and invoices.
Pipe installation at an urban construction site
Public sewer mains are built and owned by the county. The connection from your home to that main is the private side of the job.
📋
Ask before you sign anything
Ask WASD about any connection charges and whether any assistance applies to your address, and ask every contractor exactly what their quote includes: tank pump-out, abandonment method, permits, the line itself, any pump equipment if a pressure system is required, and yard restoration. A clear scope up front is the best protection against surprise costs later.

Common surprises, and how to avoid them

  • The house drain is in worse shape than expected. Many homes in north Dade were built decades ago with cast-iron drains under the slab. Connecting a corroded line to a brand-new sewer does not fix it. A camera inspection tells you before the work starts.
  • Nobody knows exactly where the tank is. Older systems are not always where the original drawings say. Locating the tank and the outlet early saves digging in the wrong place.
  • Landscaping, pavers or a slab are in the way. Plan the route with your yard in mind, and agree in advance on what will be restored and how.
  • The tank is left in the ground the wrong way. A tank that is not properly pumped and filled or removed can collapse years later. Make sure abandonment is part of the permitted work.
  • Waiting for the last minute. When a whole neighborhood connects at once, schedules fill up. Getting information and quotes early gives you more control.

Frequently asked questions

How do I know if sewer is available on my street?

Check with Miami-Dade County and WASD. They can confirm whether there is a public sewer you can connect to, what program applies to your address and what the current requirements are. If you are not sure where to start, call us and we will point you in the right direction.

Can I keep using my septic tank once sewer is available?

Rules and timelines can depend on your situation and the program, so ask the county and WASD what applies to you. Until you connect, keep maintaining the septic system as usual, with regular pump-outs and attention to the drain field.

What happens to the old septic tank?

It is pumped out one last time and then removed or filled in place according to code. Leaving an old tank in the ground without proper abandonment can create a safety hazard and problems when you sell.

Do you handle conversions outside North Miami Beach and Miami Gardens?

Yes. We work throughout Miami-Dade and Broward, including Aventura, Hialeah, Miami Springs, Coral Gables and Miramar. See our sewer and storm drain services for more.

The bottom line

Moving from septic to sewer is one of the biggest plumbing projects a South Florida homeowner will face, but it does not have to be complicated. Confirm your eligibility and requirements with the county and WASD, inspect your existing line before anything is dug, get a written scope that covers the tank, the line, permits and restoration, and keep every document. Do it that way and you finish with a cleaner, more reliable system and one less thing to worry about every rainy season.
