Liquid Waste Program Environmental Health is responsible for protecting public health and the environment from the potential adverse health and environmental impacts associated with on-site individual sewage disposal systems. This responsibility is carried out through the review of septic system design proposals, review of septic system design criteria, and inspection of new septic system construction and repair of existing systems to determine conformance with applicable codes.
Environmental Health also manages the proper disposal of liquid waste collected from licensed septage haulers through a permit issuance and inspection process.

An on-site individual sewage disposal system, also referred to as a septic system, is used for the disposal of wastewater from structures that do not have access to a public wastewater treatment facility. Wastewater from a septic system may contain many types of contaminants such as nitrates, harmful bacteria, chemicals, and viruses. If a septic system is designed incorrectly or is not constructed in conformance with applicable codes and construction practices, contaminants may enter the groundwater supply or may result in the ponding of sewage above ground causing direct exposure to people and animals.
