A Guide to Septic System Permits and Regulations
Septic systems are critical for dealing with household waste, especially in homes in areas that aren’t served by municipal sewage systems. Whether you need to install a system on a new construction or replace an aging or faulty system, it’s important to understand the requirements. Use this guide to better understand septic systems and what you need to know about permits and regulations. Understanding Septic Systems A septic system typically includes two main components: the septic tank and field. Waste is deposited in the septic tank first. This works to separate wastewater, called effluent, from solids that sink and floatable matter like oil and grease. The effluent then drains from the tank to the septic field. The bacteria in the septic tank slowly digests the waste that’s left behind, allowing it to eventually drain into the field. The drain field has perforated pipes that are buried between 6 and 18 inches under the soil. The pipes are laid in trenches that are commonly 2 to 3 feet wide and are filled with gravel to help ensure the water can disperse into the soil. While soil septic fields are the most common, there are other options available for the right situations.
