Document Description
A pollution study completed in October 1999 determined that surface and shallow groundwater in Orick, an unincorporated area of Humboldt County, is being polluted by an indeterminate number of existing, privately owned on-site wastewater systems. These systems are comprised of a variety of septic tanks, leachfields, and leach pits. The study found pollution to be widespread, not confined to any specific area, and attributable to many sources. The study further concluded that the existing on site wastewater systems potentially pose a public health hazard and may impair future development within the area. The general design strategy is to collect wastewater effluent from the community's individual on-site septic tanks (primary treatment) using Septic Tank Effluent Pump (STEP) systems. The collected effluent will be pumped to a recirculating gravel filter (secondary treatment), and be discharged to a subsurface disposal field. OCSD anticipates that most of the existing septic tanks and all of the leach pits will need to be retrofitted or replaced to be compatible with a STEP system. To minimize groundwater mounding, the disposal system will be located in areas with appropriate soil and groundwater characteristics with a site-specific (engineered) application rate. Storm water will likely be graded away from the gravel filters and leachfields in order to reduce infiltration to groundwater.
