The Basics of Septic System Design
Septic systems are an essential part of many rural homes and properties. They help to safely and efficiently dispose of wastewater and prevent pollution of groundwater and nearby waterways. In this article, we will discuss the basics of septic system design, including the components of a septic system, the factors to consider when designing a system, and some common issues and maintenance tips.
Components of a Septic System
A septic system comprises three main components: the septic tank, distribution box, and drain field.
Septic Tank
The septic tank is a large, underground container made of concrete, plastic, or fiberglass. It is responsible for separating and breaking down solid waste from the liquid waste that enters the tank from the house. The solid waste settles to the bottom of the tank, while the liquid waste (also known as effluent) flows out of the tank and into the distribution box.
Distribution Box
The distribution box is a small box that is typically made of concrete or plastic. Its purpose is to evenly distribute the effluent to the drain field. The distribution box is connected to the septic tank by a pipe and has several outlets that distribute the effluent to the drain field.
Drainfield
The drain field, also known as a leach field, is a series of pipes or chambers buried in the soil. The effluent from the distribution box flows into the drain field and is slowly absorbed by the soil, where it is naturally filtered and treated. The size and design of the drain field are determined by the size of the property and the number of people using the system.
Factors to Consider in Septic System Design
Several factors must be considered when designing a septic system to ensure its effectiveness and longevity.
Soil Type and Permeability
The soil type and permeability of the property are essential factors in septic system design. The soil’s ability to absorb and filter the effluent is critical in ensuring the system’s effectiveness. Soil that is too dense or does not absorb water well can cause the system to fail and result in costly repairs.
Site Characteristics and Size of Property
The site characteristics and size of the property also play a significant role in septic system design. The location of the system on the property, distance from the home, and topography must be taken into account to ensure proper installation and functionality. Additionally, the size of the property and the number of people using the system will determine the size of the septic tank and drain field required.
Local Regulations and Codes
Local regulations and codes must be followed when designing a septic system. Each state and county has specific requirements for septic systems to protect public health and the environment. It is essential to consult with local authorities to ensure that the system meets all necessary regulations and codes.
Maintenance and Accessibility
Proper maintenance and accessibility are crucial for the longevity and effectiveness of a septic system. Regular pumping of the septic tank is necessary to remove the solid waste that accumulates in the tank over time. Conserving water and reducing waste can also help prevent overloading the system. Additionally, proper use and disposal of chemicals, such as cleaning products and pesticides, can prevent damage to the system and surrounding environment.
Common Issues with Septic Systems
Septic systems can experience various issues over time that affect their performance and effectiveness.
Clogs and Blockages
Clogs and blockages can occur in the pipes leading to and from the septic tank and distribution box. Solid waste buildup or foreign objects can cause these blockages, leading to backups and overflow of the system.
Leaks and Overflow
Leaks and overflow can occur when the system is overloaded or when there is damage to the pipes or tank. This can cause wastewater to leak onto the property or nearby waterways, resulting in environmental contamination and health hazards.
Overuse and Overloading
Overuse and overloading can occur when the system is not appropriately sized for the property or when there are too many people using the system. This can lead to excess waste entering the system and causing damage and failure.
Maintenance Tips for Septic Systems
Proper maintenance and care can help prevent issues with septic systems and ensure their longevity and effectiveness.
Regular Pumping
Regular pumping of the septic tank is necessary to remove the solid waste that accumulates over time. The pumping frequency depends on the tank’s size and the number of people using the system, but it is generally recommended to have the tank pumped every 3-5 years.
Conserving Water and Reducing Waste
Conserving water and reducing waste can help prevent the overloading of the system. Simple practices such as fixing leaky faucets, using low-flow fixtures, and reducing water usage can make a significant impact on the system’s performance.
Proper Use and Disposal of Chemicals
Proper use and disposal of chemicals can prevent damage to the system and surrounding environment. Avoid flushing non-biodegradable items and use harsh chemicals, such as bleach or drain cleaners, which can kill the bacteria responsible for breaking down waste in the septic tank.
