An onsite wastewater treatment system (OWTS), also referred to as a septic system, is used for the disposal of wastewater from structures that do not have access to a public sewer / wastewater treatment utility. The Environmental Health Division (Division) Liquid Waste Program is tasked with protecting public health and the environment from the potential adverse health and environmental impacts associated with OWTS. 

Liquid Waste Program staff review OWTS design proposals and design criteria, and inspect both new OWTS construction and repairs of existing systems to ensure conformance with all applicable codes. There are three basic applications for OWTS in Ventura County: 1) design review/approval for new conventional and alternative systems, 2) construction or repair permits for conventional and alternative systems, and 3) certifications of existing systems.
