Alternative septic systems are often installed in "difficult" sites with conventional methods, but if you find water in your backyard from your septic system, you may need to upgrade or switch from a conventional septic system to something better suited to your area. There are many alternative septic systems that can accommodate sewer line plumbing, treat wastewater and dispose of it properly. Alternative septic systems include raised bed and septic mound systems, aerobic systems, disinfection and even waterless systems. The first indicator that you need to switch from a conventional septic system may be that you experience flooding or unusual water gathering in a backyard or field. If you find your conventional septic system is not adequate, it is important to act quickly to avoid being cited or fined for non-compliance.
