Signs of drainfield failure
- Standing water or spongy ground over the field
- Sewage odor outside
- Bright green stripes of grass
- Backups shortly after a pump-out
- Slow drains throughout the house
Repair, rejuvenate or replace
Some fields recover after pumping, fixing a broken baffle, or jetting the lines. A failed field is replaced, sometimes as a mounded or engineered system where the water table is high, which is common near the coast in Hernando Beach and Hudson.
Springs-area rules
A drainfield replacement is a permitted modification. Inside the Weeki Wachee springs Priority Focus Area, the county may require a nitrogen-reducing (ENR) system, unless central sewer will be available soon. The septic company can check your parcel on the state map before you get a quote. More on ENR systems.

Frequently asked questions
Can I drive or build over my drainfield?
No. Vehicles, sheds, pools and patios compact the soil and crush lines. Keep the drainfield clear and lightly landscaped.
How long does a drainfield last?
It varies with soil, water table, household size and maintenance. Regular pumping is the biggest factor you control.
