A system that is not functioning properly will release nutrient-rich and bacteria-laden wastewater into the ground water and/or surface water. A properly designed, located, constructed, and maintained septic system is imperative to protecting human health and the environment.
Regulation of Septic Systems in Idaho
DEQ has established minimum standards, Individual/Subsurface Sewage Disposal Rules (IDAPA 58.01.03), for the design, construction, siting, and use of individual and subsurface sewage disposal systems. This rule also establishes requirements for obtaining an installation permit and an installer's registration permit.
The Individual/Subsurface Sewage Disposal Rules are administered by Idaho's seven public health districts under a memorandum of understa
