Introduction

In unsewered developments across Australia, the importance of effective wastewater management cannot be overstated. These systems are crucial for treating and disposing of sewage, ensuring that our communities remain healthy and our environments stay safe. Most of these areas rely on septic tank systems to handle their sewage needs.

The purpose of wastewater treatment systems is simple yet vital: to treat and safely dispose of sewage. Without these systems, untreated wastewater could pose serious health risks and environmental hazards. Whether you’re planning to build a new home or upgrading an existing system, understanding the different types of wastewater management systems is essential. Let’s dive deep into how these systems work and which ones are best suited for residential areas.

Understanding Wastewater Management Systems

Wastewater management systems are designed to handle the sewage from homes and businesses, treating and disposing of it in a safe manner. These systems are especially important in unsewered developments, where traditional sewerage systems are not available. The primary purpose of these systems is to treat sewage composed of faecal matter and urine. This is done so that it doesn’t harm the environment or public health.

At the heart of these systems is the septic tank, a crucial component that plays a significant role in the initial treatment of wastewater. Wastewater enters the septic tank, where it undergoes separation and initial treatment before being dispersed into the soil. This process ensures that the liquid waste, or effluent, is treated and disposed of safely.

Understanding the components of a wastewater system and how they work together is the first step in choosing the right system for your home. The following sections will break down these components and explain the process in detail, providing you with a comprehensive understanding of wastewater management.

Components of a wastewater systems

A typical wastewater system includes several key components that work together to treat and disperse wastewater. The primary component is the septic tank, which is usually made from concrete, fiberglass, or polyethylene. This tank is designed to hold wastewater long enough for solids to settle to the bottom and form sludge, while oils and grease float to the top as scum.

The next component is the drainfield, which consists of:

A shallow, covered excavation
The drainfield disperses the effluent into the unsaturated soil
This area allows the wastewater to filter through the soil
The soil undergoes further natural treatment processes

Finally, the soil absorption system ensures that the treated effluent is safely absorbed and purified by the soil, preventing contamination of groundwater and surface water.

How wastewater management systems work

When wastewater enters the septic tank, it undergoes a separation process. Heavier solids sink to the bottom, forming sludge, while oils and grease float to the top as scum. This separation is crucial as it prevents these solids from clogging the drainage system. The remaining liquid, known as effluent, flows from the tank into the drainage receptacles.

The septic tank is designed with compartments and a T-shaped outlet to prevent sludge and scum from leaving the tank and clogging the drainfield. The drainfield itself is an essential part of the system, allowing pretreated wastewater to filter through the soil, where it undergoes further treatment and dispersion.

Anaerobic bacteria present in the septic tank help break down the solids, transforming them into sludge that gradually accumulates at the bottom of the tank. This process, while effective, requires regular maintenance to ensure the system continues to operate efficiently.

As the liquid effluent flows out of the tank and into the soil, it is further treated by natural processes, ensuring that it is safe for the environment.

Types of Wastewater Management Systems

There are various types of wastewater management systems, each with unique features and applications. The most common type used in Australia is the septic tank system, which includes absorption trenches or leach field style systems. These systems rely on gravity to move wastewater from the septic tank to the drainfield, where it is treated and dispersed.

Another popular option is the aerobic treatment unit (ATU), which uses forced air to enhance bacterial decomposition of waste. These units provide better pollutant reduction compared to conventional systems but require power to operate.

Lastly, mound systems are designed for areas with high water tables or shallow soil depths, providing an elevated absorption area to ensure effective wastewater treatment. Choosing the right type of system depends on various factors, including soil conditions, site requirements, and local regulations.

The following sections will delve deeper into each type of system, providing detailed information to help you make an informed decision.

Aerobic Treatment Units

Aerobic treatment units (ATUs), also known as aerated wastewater treatment systems, offer a more advanced approach to wastewater management by using forced air to enhance bacterial decomposition of waste.
