The main benefit of using a septic tank instead of a sewer is that it requires less maintenance. Septic systems require regular pumping and cleaning, but they are generally easier to maintain than sewer systems. Additionally, septic tanks can be designed for different types of waste, including greywater and food scraps, whereas sewers must be designed specifically for wastewater.
