About this service
When planning for a new septic install, costs fluctuate based on the materials used for the tank and the complexity of the leach field layout. Sloped terrain or rocky ground requires more labor and specialized equipment, which impacts the final bill. While smaller systems are more affordable, larger capacity tanks are higher.
Summer is a peak time for household water usage, especially with guests visiting. Extra laundry, frequent showers, and outdoor water use can stress an older system. If you have a busy house this season, keeping an eye on your drain speeds helps ensure everything keeps flowing smoothly throughout the warm months.

How does a septic tank actually work?
A septic tank is an underground wastewater treatment structure. It uses a combination of natural processes to treat sewage from your home. Solid waste settles to the bottom as sludge, and lighter materials like grease float to the top as scum. Bacteria in the tank break down some of the organic matter. The partially treated liquid then flows to a drain field for further purification by the soil.
