hy do some septic systems have mounds?
Many people wonder why they need a mound when they get a septic system installed, repaired or replaced. In order to understand this, you must first understand how the groundwater works here in Florida and how a septic system works with the soil and the ground water.
Here in Florida, we have water flowing through the s
oil beneath our feet. The location of this water is called the water table, and it changes elevation throughout the year. The water table’s location can vary from many feet underground to, in many cases, just below ground level. The level depends on a few different factors, including the season, the soil and the geographical location.
Not all soil is the same, some are more permeable, meaning it allows water to flow through it quickly, while other types of soil require more time for the water to flow through it.
Your septic system is designed to partially treat the wastewater coming from your home. The soil below your septic system further treats the wastewater, to the point of it becoming a part of the ground water. To be effective this process requires time and soil.
If the water table is too close to the surface the ground must be built up to increase the space between where the wastewater enters the soil and where it rejoins the ground water, giving it more time and soil to filter through. Therefore, the mounded systems are created.
