What is wastewater?

Wastewater is generated from households and businesses every single day. On average an individual produces almost 200-300 litres of wastewater per day! 99% of this is water and 1% is the contaminating waste. Hence, it is crucial that efficient systems are in place to treat the wastewater as it can contaminate the fresh water supplies, cause diseases, and affect the environment.

Types of wastewater treatment systems

If your property is not connected to the municipal sewage system, the treatment and disposal of the wastewater must occur on your property.

There are various ways in which wastewater can be treated - septic systems and home sewage treatment systems (HSTP).

Septic Systems

The septic systems use microorganisms to break down the wastewater from your home.

Home Sewage Treatment Plants

It treats both types of wastewater (greywater and blackwater) in one chamber in 3 stages - primary, secondary and tertiary. Each of these stages cleans water progressively and treats different types of pathogens.

Difference between Septic Systems and HSTPs


The septic systems uses a biological process to treat wastewater. The contaminants are further treated by the bacteria naturally present in the soil of the absorption trenches.

HSTPs use a 3 stage processes to treat wastewater which can then be released above or below the ground.


The effluent discharged from the septic system still has contaminants and cannot be released into a waterway or used for irrigation. However, the effluent from HSTP is non-polluting and can be released into the ground safely. HSTPs are better for the environment than septic systems as they treat the water to a higher quality.

Wastewater treatment approvals

For septic systems, approvals are needed from the local council. If your property is located in water catchment areas or coastal areas, you will not be permitted to install the septic system as the discharge might pollute the waterways.

HSTPs require approval from the local council and chief executive in accordance with Part 5 of the Plumbing and Drainage Act 2002.

Maintenance and Cleaning of wastewater treatment systems

HSTPs require professional servicing in accordance with the State Accreditation Approval, however, septic systems do not, therefore it is wise to enquire regarding servicing charges when looking at installing an HSTP.

Septic systems do however require pumping every 3-5 years, and HSTPs have emptying requirements that range depending on the model and process, making the upkeep requirements different for both.

Running Costs

A septic system is a much cheaper and more common option than an HSTP, however, both are relatively cost-effective to run.
