FAQ

What work fits NAICS 562991?
  • Scheduled septic tank pumping and desludging using vacuum trucks with transport of septage and delivery receipts to permitted disposal points.
  • Routine on-site inspection and effluent filter cleaning with documented tank-level measurements, photographic condition reports, and maintenance records.
  • Emergency response to septic backups with vacuum extraction, temporary bypass pumping, and containment pending repair by licensed installers.
  • Periodic maintenance contracts that include dosing chamber checks, odor control treatments, service-interval recordkeeping, and disposition documentation for removed wastes.
When is NAICS 562991 a weak fit?

  • Wastewater treatment plant operations and sludge processing - covers municipal treatment and biosolids management beyond on-site septic tank service.
  • Hazardous waste remediation or regulated hazardous-material disposal - requires specialized hazardous handling protocols and manifests beyond domestic septic septage service.
What solicitation language points to NAICS 562991?
  • Contract line items specify vacuum truck capability, service frequency, and requirement for manifests and disposal facility receipts upon delivery of septage.
  • Performance requirements call for confined-space entry training, respirator fit certification, and documented procedures for pumping, dewatering, and spill containment.
