To protect the public health from the dangers of improper sewage disposal practices, state regulations have been adopted. The regulations are designed to help insure that when a septic tank system is used, it will be constructed to meet appropriate standards, of sufficient size to handle the anticipated waste load, and that the soil is suitable for absorption of sewage. These regulations require that a permit to construct a septic tank system be obtained from the county health department. A septic tank system may not be covered with earth until an inspection is made and approval is given by the county health department sanitarian.
Remember that a septic tank system cannot be safely installed on all lots or building sites. Some lots or building sites are unsuitable because of the type of soil, terrain (too steep, too low or wet, etc.), size, ground water, rock, or other factors which would interfere with operation of the system.
Although one usually wants to keep all the trees and shrubs possible on his lot, remember that the roots of trees and shrubs growing near the septic tank system may infiltrate the absorption trenches and block the flow of sewage. It is advisable to remove trees and shrubs growing over the trenches or near the septic tank system.
