Alternative Treatment Systems
Residential onsite wastewater treatment technology is advancing beyond conventional treatment. The Onsite program provides a framework for using advanced onsite wastewater treatment systems, so health departments can properly approve the use of these new types of technologies in certain applications. Information about the environmental benefits of Alternative Technology is contained in each guidance document. Since advanced wastewater treatment and disposal options are highly case-specific, the department encourages people to speak with technology vendors and manufactures and their local, authorized representatives directly.
Below are guidance documents and specifications, which regulate alternative technology. Please note that the guidance documents are split into three categories aerobic treatment, peat biofilter treatment and drip dispersal.
