Verified from public official sources · July 21, 2026
- Pumping and records
- One month after pumping job under Wilmington regulation (state Form 4 baseline is 14 days).
- Title 5 and inspections
- Inspection report must be submitted within one month after inspection/certification; BOH existing-system inspection fee is $200 and reinspections due to improper installation are $25.
- Hauler permits
- Installer must hold current BOH installer license; hauler permit not separately verified.
- Published fees
- Existing sewage-disposal-system inspection $200; installer reinspection $25.
- Filing workflow
- Submit reports to Wilmington Board of Health.
- Caveat or conflict
- Local one-month deadline conflicts with shorter state Form 4 timing; follow the stricter applicable requirement and confirm with BOH.
