Septic systems are one of the most common ways to dispose of sewage. They are used in areas that do not have access to municipal sewer systems. A septic tank collects and treats the wastewater from your house before it is released into the soil. This blog post will discuss everything you need to know about septic systems! We will cover what they are, how they work, and how to install and maintain them!
What Is A Septic System?
A septic system is a way of disposing of wastewater from a home or business. It is a wastewater treatment system that uses a septic tank to collect and treat wastewater from your house before it is released into the soil.
The wastewater flows into the septic tank, separating into layers – solid waste settles at the bottom of the tank, heavier liquids remain in the middle, and lighter liquid (such as soapy water) floats to the top. Bacteria then break down the wastewater and helps reduce solids levels. The partly treated wastewater is then released into a drainage field or leaching bed, which filters out any remaining contaminants before releasing it back into the environment.
The United States Environmental Protection Agency (EPA) regulates septic systems and requires that they be designed and maintained properly to protect public health and the environment. They have environmental regulations in place to ensure septic systems are properly installed and maintained. These regulations are designed to ensure that septic systems don’t pollute the environment.
Why Do You Need A Septic System?
Septic systems are essential for any home or business that does not have access to a municipal sewer system.
- They provide an efficient and cost-effective way of disposing of wastewater, reducing the risk of contamination and water pollution.
- Septic tanks also reduce the amount of wastewater that would otherwise need to be transported offsite for treatment, reducing the burden on local water treatment plants.
- They also help protect the environment by preventing pollutants from entering rivers and lakes, ensuring a clean and healthy source of drinking water for everyone.
- Septic systems help reduce the risk of flooding and other water-related problems as they store wastewater until treated.
- They also reduce soil erosion and groundwater contamination, two key challenges that would otherwise be faced in areas without a septic system.
Parts Of A Septic System
Several key components of a septic system work together to treat wastewater. These include:
This is the first component of your septic system. It is a large tank that collects wastewater from your home or business and separates it into layers (solids, heavier liquids, and lighter liquids). Bacteria then break down the solids and helps reduce levels of wastewater.
The tank is made from concrete, steel, or fiberglass and holds the wastewater from your house. As the wastewater enters the tank, solids settle to the bottom and are digested by anaerobic bacteria. Grease and oils float to the top, forming a scum layer. The liquid or effluent from the septic tank flows through an outlet pipe and into the drain field or leach field.
This is a box that is connected to the septic tank. It distributes wastewater evenly among the drain field or leaching bed. This helps ensure that all parts of the field get an equal amount of wastewater and prevents clogging of any one section.
Drain Field/Leaching Bed
The drain field, also known as a leaching bed, is another part of your septic system. It is a series of pipes buried in the ground and have holes, or perforations, to allow wastewater to seep out. The drain field/leaching bed filters out any remaining contaminants before releasing them into the environment. Alternative systems use pumps or gravity to help septic tank effluent move through the system.
Risers are used to bring the septic tank and drain field above ground level. This makes it easier to access them for regular inspection, maintenance, and repair. Risers also help protect your septic system from flooding and other weather-related damage.
Types Of Septic Systems
You can choose from several types of septic systems, depending on your location, budget, and needs. These include:
Conventional Gravity Septic System
This is the most common type of septic system. It uses gravity to move wastewater from the septic tank through a drain field or leaching bed. This type of system is ideal for homes with a large drain field area.
Pressure-Dosed Septic System
This septic system uses pressurized water to move wastewater from the septic tank through the drain field or leaching bed. It is more efficient than a gravity septic system and is great for locations with limited space for a drain field.
Aerobic Treatment Unit (ATU)
This septic system uses oxygen to break down and treat wastewater before it is released into the environment. It is more efficient than other types of septic systems, requires more maintenance, and can be more expensive. This type of septic system is great for areas with high water tables or limited space for a drain field.
Tools For Installing A Septic System
Installing a septic system can be complicated and requires the use of specialized tools. Some common tools that you will need include:
- Shovel: This is an essential tool when it comes to digging the septic tank, drain field, and distribution box.
- Backhoe: This is a large piece of equipment used to dig trenches for the pipes that connect the septic system components.
- Trencher: This tool creates narrow trenches for laying pipe in hard-to-reach areas.
- Level: This tool is used to ensure the septic tank, distribution box, and drain field are level before installation.
- Compactor: Once the soil has been dug up for the installation of the septic system components, a compactor is used to compact it to support the weight of a septic system.
- Septic Tank Liner: This is used to line the septic tank, which helps protect it from any corrosion or other damage.
- Pumps And Alarms: These are used in some systems to ensure that wastewater is properly treated and pumped out.
- Drainage Pipes: Used to carry wastewater from the septic tank to the drain field or leaching bed, where it is filtered before being released into the environment.
How To Install A Septic System
Installing a properly functioning septic system requires specialized knowledge and experience. It is important that you consult with a professional before embarking on this project. Generally speaking, the steps for installing a septic system include the following:
Planning And Designing
This involves researching local regulations, determining the size of your septic system, and choosing the type that best suits your needs.
The next step is to dig a number of trenches for the pipes, septic tank, and drain field/leaching bed.
Once the trenches are dug, you can begin to install the septic tank, distribution box, and other components of your septic system.
This step involves connecting all the components of your septic system with drainage pipes.
Installing A Liner
Once the septic system’s components are in place, a liner is installed to protect against any corrosion or damage.
This is when you fill in all the trenches with soil and compact it so that they can support the weight of your septic system.
The last step is to test your septic system to ensure it is installed correctly and properly functioning.
