A septic system is an effective way to treat wastewater and reduce pollution in your local environment. It can also help protect groundwater by treating waste before it enters waterways or oceans. Additionally, a septic tank helps to remove harmful substances from wastewater, making the water safe for use around your home. Lastly, a septic tank can be used as a source of renewable energy since methane gas can be extracted from the tank's contents.
