The answer to 'sewer line vs' is that a sewer line and a septic system are two different ways to handle wastewater from your home. A sewer line connects your home to a municipal sewage system, while a septic system treats and disposes of wastewater on your own property. The main differences are the installation, maintenance, and costs involved with each option.
Sewer lines are typically more expensive to install upfront, as they require connecting to the public sewer system. However, they have lower ongoing maintenance costs since the municipality is responsible for maintaining the main sewer lines. Septic systems have a lower initial installation cost, but require regular maintenance and pumping to keep the system functioning properly.
