What is an Individual Sewage Disposal System?
An Individual Sewage Disposal System (ISDS) is a privately owned and maintained sewage disposal system. They are commonly referred to as septic systems or onsite wastewater treatment systems. All ISDS have two basic components: a two-compartment septic tank and a disposal field. The septic tank serves to separate and store solid material and the disposal field allows wastewater to percolate into the ground. In Ventura County, there are two general types of ISDS: conventional and alternative. Conventional systems use leach lines, leach beds or seepage pits for the disposal field component. Alternative systems use an above ground mound or below ground gravity sand filter for the disposal field component.
