What is different about installation in Doral
New septic systems in Doral are uncommon: most of the city was built after 2000 with public sewer, and Ordinance 22-83 bans a new septic system where a gravity sewer or force main abuts the lot. The 491 septic parcels the County counted in 2020 are mostly older properties and businesses.
Where a new system is allowed, groundwater sets the design. The County's 2018 study found about 92% of Doral's modelled residential septic parcels within 42 inches of peak groundwater, so a new drain field usually has to be raised to sit 36 inches above the wet-season water table.
For a Doral business site, the treatment standard rises with use and flow under the County ordinance, and inside a wellfield protection area such as the Northwest Wellfield a non-residential use on septic needs a DERM permit as well. A sewer connection through the County's commercial corridor work may be the better plan.

What type of system will I need for my property in Doral?
Miami-Dade County prohibits Type 1 conventional systems for new installations. You will need a Type 2, Type 3, or Type 4 system depending on your property type, wastewater volume, and proximity to surface water bodies. Our engineers determine the appropriate system type during site evaluation.
Do I need permits for septic tank installation in Doral?
Yes, prior written approval from the DERM Director is mandatory before any new septic system installation. We handle all necessary permits and coordinate with DERM throughout the process.
Doral questions
Can a Doral warehouse install a new septic system?
Only where sewer is not available. It needs DERM approval and, in a wellfield protection area, a DERM wellfield permit for a non-residential use on septic. Ask about the County's Commercial Corridors sewer program first.
