How Do Septic Tank Systems Work?


A large concrete or steel septic tank can hold up to 1,000 gallons of water. Wastewater comes down into the tank on one side from your New Hampshire home’s sewage pipes and leaves the tank on the other side. Gases go up through a vent pipe through the roof of the house. Wastewater flows out of the septic tank and into a drain field made of perforated pipes, deeply buried and covered in gravel-filled trenches.

The drain field tends to be about 6 feet deep and 2 feet wide. Ultimately, the size of the drain field depends on how well the soil absorbs water, with slow-absorbing soil requiring a larger drain field. About 3 feet of gravel covers the drain pipes, with dirt filling the remainder.

Installing a septic tank system is best left to a licensed advanced wastewater treatment system installer, who can anticipate what size drain field your New Hampshire system will need. Whether you’re working on a new build or a remodel, make sure your septic expert and installer openly communicates with your contractor or builder.
