Georgia's DPH establishes guidelines for septic system design and installation, emphasizing the need for systems that can effectively manage high rainfall and protect the state's numerous water resources. The state's soil composition, ranging from clayey soils in the Piedmont to sandy soils in the Coastal Plain, significantly impacts excavation ease and leach field performance, thereby influencing labor costs and material selection. The humid subtropical climate, characterized by hot summers and considerable rainfall, necessitates robust system designs to prevent failures and ensure long-term functionality, potentially contributing to higher initial installation expenses.
