How Does a Mound Septic System Work?

A traditional septic system uses a drain or leach field that filters the effluent that comes from the septic tank before it enters the ground water. However, not all areas can facilitate a drain field, either due to the type of soil or environmental concerns. An alternative to a drain field is a mound system, a filtering element that is created above ground. If you are considering adding a septic system or need to replace a drain field, here is what you need to know about mound septic systems.

Mound System Basics

Mound septic systems work similar to a traditional system but are a bit more complicated. As wastewater or effluent exits the tank, it is sent to a dosing chamber instead of a gravity distribution box. The dosing or pumping chamber regulates how much effluent is allowed to the enter the mound filter to ensure it is not overloaded. The mound is built with a network of pipes that transport wastewater from the dosing chamber. Wastewater filters down through the mound sand, removing contaminants before it reaches the ground surface underneath.

Mound systems offer a way to install a septic system in almost any area, even when a leach or drain field is not possible. They are more expensive to install, but if maintained correctly, they can last for decades. Although they do require a large mound to be in your yard, it can and should be planted with grass or small plants.

If you need to use a mound septic system, it is vital to stay on top of maintenance and use preventive septic care habits. Routine inspections and pumping the tank can help prevent issues that can damage your mound system and protect your investment.
