Frequently asked questions
Who issues a drain field permit?
Onsite sewage permits are usually issued by the county or state health department rather than the building department, and a soil evaluation is normally required before a permit is issued.
Can a failed drain field be repaired instead of replaced?
Sometimes. Pumping, jetting or fixing a broken distribution box can restore a field that failed from overload rather than age. A field that has lost soil acceptance has to be replaced.
Do I need a permit for drain field replacement in West Palm Beach, FL?
In most jurisdictions this work is permitted and inspected. Requirements are set locally, so confirm the current application and inspection checklist with your building department before work starts.
How long does drain field replacement take?
2-4 days of work, 3-10 weeks including evaluation and permitting. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are design flow, usually set by bedroom count; soil percolation rate and depth to water table; conventional trenches, chambers or an engineered mound system.
