Expert Mound Septic System Installation in Northern Virginia and the Shenandoah Valley
Choose Excellence: With Our Mound Septic System Installation!
Mound septic systems are an advanced, alternative solution for properties where a conventional septic system isn’t feasible. If your Northern Virginia property has a high water table, shallow bedrock, or impermeable soil, a mound system can be the ideal way to achieve effective wastewater treatment and disposal.
What is a Mound Septic System?
A mound system is an engineered drain field that’s constructed above the natural ground level. It’s a highly effective solution designed to overcome challenging site conditions. Instead of relying on the natural soil for purification, a carefully constructed mound of sand and gravel provides the necessary filtration before the treated water reaches the surrounding earth.
How a Mound System Works
The process begins as wastewater flows from your home into the septic tank. From there, the clarified effluent moves into a pump chamber. When a specific volume is reached, a pump is activated, sending the effluent to the top of the mound through a network of perforated pipes.
The wastewater is then evenly distributed across a layer of sand, where it trickles down through the mound’s various layers. The sand provides a highly effective medium for purification, treating the wastewater as it moves through the system. By the time the effluent reaches the natural soil below, it is clean and safe for absorption.

When a Mound System Is the Right Solution
You might need a mound system if your property’s soil conditions are unsuitable for a traditional drain field. This typically includes:
- High Groundwater: Properties with a high water table may not have enough space between the soil surface and the water level for proper wastewater treatment.
- Shallow Bedrock: If solid rock is close to the surface, it can prevent the proper absorption of wastewater.
- Slow-Draining Soils: Extremely dense soils like clay can prevent wastewater from percolating, causing it to back up.
Mound systems are a reliable and effective way to overcome these challenges, protecting both your property and the surrounding environment.
