​Individual Sewage Systems: A Sewage System Installer must be certified by the State of West Virginia. Homeowners and Sewage System Installers must obtain permits to install an Individual Sewage System. A septic permit must be obtained before any building permits will be issued.

The cost of a septic system can run anywhere from $5000-$50,000. Many factors will influence how much you will spend on replacement.

Septic tanks shall be rectangular in plan, cross-section and longitudinal view. The length to liquid depth to width ratio should be approximately equal or greater than 2 to 1 to 1 (2:1:1) and less than or equal to 3 to 1 to 1 (3:1:1). In no case shall the liquid depth be less than four feet or greater than eight feet.

Aerobic/Advanced treatment units (ATUs) The ATU is arguably the most commonly implemented advanced septic system and it primarily uses oxygen for the advanced treatment of wastewater. By adding oxygen, ATUs break down the organic matter and thereby reduce the nutrient loading and pathogens.
