Septic System Information

septiclogoThe Environmental Health section issues permits for private sewage disposal systems and inspects new construction of private sewage septiclogodisposal systems. They also provide consultation for private water supplies. The environmentalists investigate complaints of septic system failures that contribute to land pollution. They also provide information on health hazards such as improper solid and hazardous waste disposal. They work closely with the Indiana Department of Environmental Management and the Indiana State Department of Health.

The Washington County Environmentalists inspect all residential septic system sites in the county prior to construction and after installation. If you are dealing with a commercial site, State approval must be granted before proceeding. You may call the Health Department for more information.

The Indiana State Health Department has provided funding to allow the Local Health Departments to purchase Mosquito Dunks, a larvicidal product. The active ingredient is Bacillus thuringiensis israelensis, a bacterial spore that is safe for animals and fish. It kills mosquitoes by scratching up their stomach and intestinal linings, making them unable to ingest food. Mosquito Dunks are free to the public as long as our supply lasts. Simply call the Health Department at 812-883-5603, Extension 2004, and let us know how large your area of standing water is. A calculation can be made as to how many Dunks you will need.


Ticks are small, insect-like animals that live in woodland or in mixed shrub and grassland environments. They have two body segments and eight legs while insects have three body segments and six legs. The life cycle of ticks involve the following three stages: egg. Larva. Nymph, and adult.

About fifteen different species of ticks occur in Indiana . Only four species are normally encountered by people and their pets. These are the American dog tick, Dermacentor variabilis; the lone star tick, Amblyomma americanum; the blacklegged tick (also known as the deer tick or the Lyme disease tick), Ixodes scapularis, and the brown dog tick, Rhipicephalus sanguineus. In Indiana , ticks are responsible for transmitting several diseases. The three most common are Rocky Mountain spotted fever, Lyme disease, and ehrlichiosis. For more information on ticks, diseases, and prevention, see “Other Links”.
