Confirm Why the Field Failed
Review solids carryover, uneven flow, compaction, excessive water use and seasonal saturation. Rebuilding without addressing the cause can repeat the problem. Inspect the tank outlet and dosing arrangement along with the receiving soil.
Check Sewer and Available Land
Before committing to a new field, ask whether the property must connect to available sewer. Identify suitable field area without occupying required setbacks or unobstructed space. Pools, paving, sheds and neighboring wells can restrict the layout.
Elevation Matters as Much as Area
The site evaluation establishes soil and seasonal high groundwater conditions. Some sites need an elevated or filled field, dosing or another approved design. A sandy-looking yard and a large tank do not prove a conventional field will meet the requirements.
Submit and Build the Approved Scope
DOH-Orange reviews the repair or replacement application. Provide the existing record, failure information, site evaluation and proposed layout. Coordinate any separate city or county work, arrange required inspections and retain final system documents.
Keep the New Field Working
Fix running toilets, spread laundry loads out and keep roof runoff away from the disposal area. Protect it from traffic, paving and deep-rooted landscaping. Maintain the tank and filter so solids do not clog the replacement field.
