If your property isn’t connected to the mains sewer network, choosing the right septic system is one of the most important decisions you’ll make. Whether you’re building a new home, developing a rural property, or managing a commercial site, a well-designed wastewater system protects your investment, the environment, and the health of everyone using your property.
At Bennetts Concrete, we supply and install quality septic and wastewater solutions across the South Coast, helping property owners find systems that are reliable, compliant and built to last.
What Is a Septic System?
A septic system is an on-site wastewater treatment solution designed to safely manage household or commercial wastewater where sewer services aren’t available. Rather than sending wastewater to a municipal treatment plant, septic systems collect, treat and disperse wastewater directly on your property.
The right system depends on several factors, including:
- Property size
- Soil type
- Number of occupants
- Water usage
- Local council requirements
- Environmental conditions
Selecting the correct system ensures efficient operation while meeting Australian standards and local regulations.
Types of Wastewater Systems
Every property is different, which is why there is no one-size-fits-all solution.
Septic Tanks
Traditional septic tanks remain one of the most popular wastewater solutions for rural and residential properties. They separate solids from wastewater before partially treated water is distributed to an approved disposal area.
Modern concrete septic tanks offer exceptional durability and require minimal maintenance when properly installed and maintained.
Aerated Wastewater Treatment Systems (AWTS)
Aerated Wastewater Treatment Systems use oxygen and beneficial bacteria to further treat wastewater, producing higher quality effluent suitable for approved irrigation systems.
AWTS units are often ideal for:
- Smaller blocks
- Environmentally sensitive areas
- Properties requiring irrigation disposal
- Homes with higher wastewater demands
Commercial Wastewater Systems
Commercial developments require larger, more sophisticated wastewater solutions capable of handling higher daily volumes.
These systems are commonly used for:
- Accommodation facilities
- Schools
- Commercial buildings
- Industrial sites
- Agricultural operations
- Community facilities
Commercial systems are carefully designed to meet regulatory requirements while delivering long-term reliability.
Why Concrete Remains the Preferred Choice
Concrete septic tanks continue to be the preferred option for many property owners due to their proven strength and longevity.
Some of the benefits include:
- Exceptional durability
- Long service life
- Resistance to ground movement
- Low maintenance requirements
- Suitable for Australian conditions
- Excellent structural integrity
A quality concrete tank represents a long-term investment that can provide decades of dependable performance.
Wastewater Disposal Is Just as Important
Installing the tank is only part of the wastewater solution. Proper disposal systems ensure treated wastewater is safely distributed back into the environment.
Depending on your property’s requirements, this may include:
- Subsurface irrigation
- Semi-fixed surface irrigation
- Sprinkler irrigation
- Absorption trenches
- Pressure dosed absorption trenches
- Stormwater swales
- Upslope and downslope diversion banks
Correctly designed disposal systems help maximise efficiency while protecting surrounding land and waterways.
Why Professional Installation Matters
Even the highest quality septic system can underperform if it’s installed incorrectly.
Professional installation ensures:
- Correct sizing
- Proper site preparation
- Compliance with council requirements
- Efficient wastewater flow
- Long-term system performance
- Reduced maintenance issues
Working with experienced installers also helps avoid costly mistakes that may require rectification later.
