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

  1. Understanding Septic Systems

    The most common way to treat and dispose of wastewater in rural homes is through the use of an onsite disposal system. The majority of onsite disposal systems in the U.S. are septic systems. Learn the basics of a typical septic system.

  2. 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.

  3. Understanding and Maintaining Mound Systems

    A mound system is a type of non-standard wastewater treatment system with an elevated drainfield. Learn more about maintaining your mound system.

  4. Maintaining Your Pressure Distribution System

    Information to help you understand your pressure distribution system, and keep it operating safely at the lowest possible cost.
