Septic design and permits in Pinecrest: the short answer

Designing a septic system in Pinecrest starts with two questions: is public sewer available at the lot, and how close does groundwater come to the surface in the wet season? The answers decide whether you can use septic at all and how high the drain field has to sit to meet Miami-Dade's 36-inch separation rule.

Groundwater is the main design constraint here. In the County's 2018 study, 18% of Pinecrest's residential septic parcels already reached peak groundwater within 42 inches of the surface, and the County projected 35% by 2030. A design that would have been a simple trench system in 1970 is now often a raised or mound drain field with an advanced treatment unit.

Permits come from two offices. The Florida Department of Health in Miami-Dade issues the construction permit after a site evaluation, and DERM approves new and whole replacement systems under Ordinance 22-83, with plans signed and sealed by a Florida professional engineer. We prepare one package that answers both.

What the numbers say about Pinecrest

  • In the County's 2018 groundwater study, 926 of Pinecrest's 5,088 modelled residential septic parcels (18%) already reached peak groundwater within 42 inches of the surface; the projection for 2030 was 1,797. (Miami-Dade, 2018)
  • The 2018 study also counted 44 non-residential septic parcels in Pinecrest, 9 of them at the 42-inch groundwater threshold. (Miami-Dade, 2018)
  • The County asks residents of municipalities such as Pinecrest to check sewer status with their local water and sewer department. (Miami-Dade WASD)

Septic design and permits in Pinecrest: questions

Who approves a septic design in Pinecrest?

Two agencies: the Florida Department of Health in Miami-Dade issues the construction permit, and Miami-Dade DERM must approve any new or whole replacement system under Ordinance 22-83. The village does not issue the septic permit itself.

Why does the wet-season water table matter so much for a Pinecrest design?

Because the drain field bottom must sit at least 36 inches above it under County rules. On lots where groundwater rises close to the surface each summer, that pushes the field up, which drives the cost and the layout.
