Wastewater Programs
Types of Programs
The land use program performs periodic inspections and monitoring for:
- Septage and Grease Trap Pumper Permits: California Health and Safety Code and Humboldt County Code require that those who engage in this activity in Humboldt County be registered, permitted and inspected annually by our office.
- Nonstandard Onsite Sewage Disposal System Operating Permits and Inspections: Sewage Disposal systems as defined in Humboldt County Code section 616-2(b) require operating permits and periodic inspection. We track the existence and performance of these systems and report to the Regional Water Control Board.
Wastewater System Maintenance Guidelines

Non-standard Onsite Wastewater Treatment System
A non-standard onsite wastewater treatment system typically uses something in addition to a septic tank to treat effluent and/or uses other than a gravity-flow drainfield. Practice routine maintenance to prolong the life of these systems.
