Core Services
From raw land due diligence through final permit issuance, we manage every phase of the onsite sewage process so your project stays on schedule.
Comprehensive lot-level and parcel-wide assessments covering soil profiles, percolation rates, water table depth, topography, and setback compliance — everything DEP needs before they ask.
Learn more →Certified soil evaluations including native soil morphology, permeability classification, and high-water table determination — the foundation of every approvable OSTDS design.
Learn more →Full-service permit application management for construction, repair, and operating permits under both DEP (Chapter 62-6 FAC) and county health authority jurisdiction. We know the reviewers — and what it takes to get approved.
Learn more →Large-scale OSTDS planning for residential subdivisions, planned unit developments, and rural communities. We design wastewater strategies for entire lots before a single shovel breaks ground.
Learn more →Pre-purchase and pre-entitlement assessments that tell you whether a parcel can support the density you need. Avoid costly surprises before you close.
Learn more →Direct engagement with DEP and county health authority reviewers on your behalf. Pre-application meetings, variance requests, and appeals — we speak the language of the agencies that approve your projects.

We manage the full OSTDS lifecycle so your team can focus on building. Here’s how a typical project flows through our process.
We review site plans, parcel data, and project goals to define the scope and flag any early regulatory considerations.
Certified soil profile analysis and percolation testing across the parcel. We document everything DEP requires for the evaluation package.
Drainfield layout, system sizing, and technology selection based on soil findings, lot constraints, and project density.
We prepare and submit the complete permitting package and manage all back-and-forth with DEP or county health reviewers through approval.
Final permit in hand. We stay available for field questions, inspection coordination, and any as-built documentation required.
About GMB
GMB Septic Permitting, LLC was founded by a former Director of Environmental Health for Santa Rosa County. That background isn’t just a credential — it means we know exactly how permit reviewers think, what they look for, and where applications stall. We built our practice to eliminate those bottlenecks for our clients.
We specialize in large-scale and complex onsite wastewater projects: multi-lot subdivisions, rural land developments, and parcels where standard solutions don’t apply. Our clients are developers, engineers, and builders who can’t afford delays at the permitting stage — and who need a partner who can navigate the regulatory landscape without hand-holding.
Why GMB
We’ve sat on both sides of the permit desk. That changes everything about how we prepare and manage your projects.
Direct working relationships with DEP and county health reviewers built over two decades in public environmental health service.
We know what reviewers reject and why. Our applications are thorough and organized — reducing back-and-forth and keeping your timeline intact.
From single-lot evaluations to full subdivision wastewater planning across dozens of parcels, we have the field capacity and process to deliver at scale.
No call centers, no junior staff runaround. You work directly with experienced professionals who know your project from day one.
