(1) This chapter shall be known and may be cited as the “Mississippi Individual On-Site Wastewater Disposal System Law.”

(2) It is the purpose of the Legislature through this chapter to protect human health and the environment while providing for reasonable use of individual on-site wastewater disposal systems. The Legislature finds that continued installation and operation of individual on-site wastewater disposal systems in a faulty or improper manner, in a manner that lacks essential maintenance for the system, or in areas where unsuitable soil and population density adversely affect the efficiency and functioning of these systems, has a detrimental effect on the public health and welfare and the environment through contamination of land, groundwater and surface waters. The Legislature, therefore, expresses a general preference for the installation and operation of centralized wastewater treatment systems in Mississippi, where feasible. The Legislature recognizes, however, that individual on-site wastewater treatment and disposal systems help meet the needs of the state’s citizens, especially in rural locations, and can be rendered ecologically safe and protective of the public health if the systems are designed, installed, constructed, maintained and operated properly. It is the intent of the Legislature to allow the continued installation, use and maintenance of individual on-site wastewater disposal systems in a manner that will not jeopardize public health and welfare or the environment.
