The mound or raised drain field
filters and treats wastewater using layers of gravel, sand, and soil to remove
impurities and reduce contamination risks.
The Components of
a Mound Septic System
In
a mound septic system, you'll find three main components: a septic tank, a
dosing chamber, and a mound or raised drain field.
The
septic tank is where the wastewater from your home goes first. It separates the
solid waste from the liquid waste, allowing the solid waste to settle at the
bottom and the liquid waste to flow into the dosing chamber.
The
dosing chamber is responsible for evenly distributing the liquid waste to the
mound or raised drain field. This field is built above ground level to ensure
proper filtration and treatment of the wastewater.
The
mound or raised drain field consists of layers of gravel, sand, and soil, which
help to remove impurities and pathogens from the wastewater before it returns
to the environment.
Site Evaluation
and Design Considerations
To
ensure proper functionality of your mound septic system, it's important to
carefully evaluate the site and consider various design factors. Here are some
key considerations:
Site
Evaluation: - Determine the soil type and its ability to absorb and treat
wastewater. - Assess the groundwater level to ensure it's below the proposed
drain field elevation. - Evaluate the slope of the site to ensure proper
drainage.
Design
Factors: - Size the septic tank appropriately based on the number of occupants
and estimated wastewater flow. - Consider the size and configuration of the
mound to accommodate the required drain field area. - Determine the appropriate
height of the mound to raise the drain field above the groundwater level.
Construction and
Installation Process
You'll
begin the construction and installation process of your mound septic system by
preparing the site and excavating the area for the septic tank and drain field.
First,
ensure that the chosen location meets all necessary setback requirements. Once
the site is selected, mark the boundaries for the mound and mark the location
for the septic tank and drain field.
Use
a backhoe or excavator to dig a hole for the septic tank, making sure to follow
the manufacturer's specifications for dimensions and depth. Next, excavate the
area for the drain field, ensuring proper slope for wastewater flow.
Install
the septic tank according to the manufacturer's instructions and connect it to
the drain field. Finally, fill the area around the septic tank and drain field
with suitable fill material, compacting it in layers to create the mound.
Understanding the
Function of the Septic Tank
Your
understanding of the function of the septic tank is crucial for knowing how the
mound septic system operates effectively.
The
septic tank is the primary component of the system, responsible for the initial
treatment of wastewater. Here's a breakdown of its role in the mound septic
system:
•
The septic tank receives
wastewater from your house and separates it into three layers: solids, liquids,
and scum.
•
Solids settle at the bottom and
form sludge, while scum floats at the top.
•
Liquids, known as effluent, are
discharged into the drain field for further treatment.
The
septic tank's main function is to capture and hold solids, allowing them to
decompose over time. This prevents them from clogging the drain field and
ensures proper effluent distribution.
Understanding
the septic tank's role is essential for maintaining the functionality of the
mound septic system and preventing issues such as clogs and backups.
The Role of the
Distribution Box in Mound Systems
The
distribution box plays a vital role in the functionality of mound septic
systems by evenly distributing effluent to the drain field. This component is
typically made of concrete or plastic and is located between the septic tank
and the drain field.
Its
purpose is to collect and distribute the effluent from the septic tank to the
drain field pipes in a controlled and evenly distributed manner. The
distribution box contains multiple outlets or distribution lines that connect
to the drain field pipes. These outlets are equipped with baffles or weirs to
regulate the flow of effluent and ensure equal distribution across the drain
field.
How Effluent Is
Treated in Mound Systems
Effluent
in mound systems is treated through a process that involves aerobic bacteria
breaking down organic matter in the drain field. This treatment method ensures
that the wastewater is properly treated before being released into the
environment. Here is a deeper look into how this process works:
•
First, the effluent is
distributed evenly across the drain field. This helps to prevent any overload
on specific areas and promotes even treatment.
•
Once the effluent reaches the
drain field, the aerobic bacteria start their work. These bacteria thrive in
oxygen-rich environments and are responsible for breaking down the organic
matter present in the wastewater.
•
As the bacteria break down the
organic matter, they convert it into simpler compounds, such as carbon dioxide
and water. This process helps to remove harmful substances and pathogens from
the effluent.
•
The treated effluent then
percolates through the mound system's sand fill, which acts as a natural
filter, further removing any remaining impurities.
•
Finally, the treated effluent
is discharged into the surrounding soil, where it undergoes further filtration
and purification before entering the groundwater system.
