New Septic System Installation in Hernando County
Building on a lot with no sewer hookup? A new septic system starts long before the digging — with soil testing, system design, and a Health Department permit. We connect you with a licensed local company that handles the whole sequence.
Reminder: we're a referral service — we match you with the licensed company; they design, permit, and install the system.
The Sequence
From raw lot to working system
Soil & site evaluation
The company tests your lot's soil and seasonal high water table. These results decide what kind of system your lot can support.
Design & OSTDS permit
The system is designed to Florida code for your home's size, and the permit application goes to the Florida Department of Health in Hernando County.
Installation
Tank set, drain field built, lines connected — by the licensed company, to the approved plan.
Inspection & sign-off
The installation is inspected before it's covered and approved, giving you a documented, permitted system from day one.
Why Lots Differ
How much does a new septic system cost in Hernando County? [2026]
Home size & system size
Florida code ties tank and drain field size to the home. A bigger home means a bigger permitted system.
Soil & water table
Hernando County's sandy inland soils drain differently than low coastal lots near Hernando Beach. High water tables can require raised or mound designs — a major quote factor.
Site preparation
Clearing, fill, and grading needs on a raw lot all factor into the installation figure.
Permits & inspections
OSTDS permitting and required Health Department inspections are a standard part of every legitimate new install.
New Installation FAQ
New septic system questions, answered in plain English
What's the first step for a new septic system?
A soil and site evaluation. The licensed company tests the soil and checks the water table on your lot, because those results determine the system design. The OSTDS permit application to the Florida Department of Health in Hernando County is built on that evaluation.
What does a new septic system installation cost?
It depends on your lot and home: required system size, soil conditions, the seasonal high water table, whether the site needs fill or a mound design, permit requirements, and access. A licensed company evaluates the lot first, then quotes the actual job.
How long does a new system last?
A properly installed, maintained system typically lasts about 25 to 30 years. Regular pumping on the schedule your installer recommends is the biggest factor in reaching that lifespan.
Can any lot get a septic system?
Most can, but not all — and some need engineered designs because of soil or water-table conditions. The site evaluation and OSTDS permit review exist to determine that before anyone digs.
Who pulls the permit?
The licensed septic company you hire files the OSTDS permit with the Florida Department of Health in Hernando County and coordinates inspections. Septic installation is licensed work in Florida — not a DIY or handyman job.
