Examples of commercial facilities are apartments, subdivisions, mobile home parks, churches, factories, gas stations, groceries, convenience stores, post offices, restaurants, taverns, golf course clubhouses, campgrounds, and veterinary, dental, and medical offices. Staff review and approve plans and specifications for onsite sewage disposal systems serving any type of commercial facility. These include mobile home parks, organizational campgrounds and recreational campgrounds. Additionally, the Division reviews total facility construction for various types of facilities, as mandated by law or regulation. Program staff reviews soil surveys for on-site disposal systems, plans and specifications for water supply and sewage disposal systems to serve all types of public and commercial facilities. The Onsite Sewage Disposal Program promotes use of technologically correct onsite sewage disposal methods for one and two family dwellings beyond the reach of sanitary sewers. More than 800,000 onsite sewage disposal systems are currently used in Indiana Local health departments issue more than 15,000 permits per year for new systems, and about 6,000 permits for repairs. Onsite sewage disposal systems (i.e., septic systems) are those which do not result in an off-lot discharge of treated effluent, typically consisting of a septic tank to settle out and digest sewage solids, followed by a system of perforated piping to distribute the treated wastewater for absorption into the soil.
