Wastewater Treatment Systems

What is wastewater?

Wastewater is a normal part of life, with every home and business generating some form of wastewater every single day. Wastewater is actually 99% water with only 1% being the things that you’ve added as you’ve used it. For some perspective, a typical family of 4 produces 400-500 litres of wastewater a day, so it is crucial that efficient and effective systems are in place to deal with all the discharge. It is also worth noting that as the general population becomes more eco-conscious and vocal regarding environmental issues, an additional push is occurring to ensure the eco-friendly release of wastewater into ecosystems, no matter the system.

Types of Wastewater Treatment Systems

Due to the differing types of wastewater (which is a topic for another day), there are varying ways in which wastewater is required to be treated. To make things a little simpler, as the topic can get a little confusing, there are two different ways in which wastewater can be treated on your property - septic systems and home sewage treatment systems. Municipal sewerage systems will not be discussed, so check out your local Council page if you want to know about these!

So if your property isn’t connected to the Municipal sewerage system, the treatment and disposal of wastewater must occur on your property. This is achieved through these 2 main systems:

Septic Systems

Septic Systems are the old septic tanks that have been used since we first started treating wastewater. The septic system uses microorganisms in a biological process to break down the wastewater.

Home Sewage Treatment Plants (HSTP)

Home sewage treatment plants, otherwise known as HSTPs, are the other option when it comes to wastewater treatment. Unlike the septic system, the HSTP has three stages to treat the wastewater to a higher level than a septic system.

What is the best Wastewater Treatment System?

This is not an easy answer to give as every need is different. In some cases a septic system will be more than adequate and the better solution for you and other times it will be the home sewage treatment plant. But here are a few points to consider.

What’s the difference between septic systems and HSTPs?

There are a few positive and negative differences between the systems, including :

The process used

Septic systems utilise a biological process to treat wastewater which can only be released below ground once the process is complete due to the levels of contaminants still present. HSTPs however use a more complicated filtration, biological and mechanical process and the treated wastewater can be released both above and below ground.

The resulting effluent

The effluent or ‘treated wastewater’ that is released from a HSTP is non-polluting, meaning it is clean water which can be released directly into a watercourse. On the other hand, the effluent from a septic system is of a polluting nature, meaning it can only be released into a disposal area for further treatment. This therefore means that a HSTP is generally better for the environment than a septic system.

The required approvals

If you are looking at installing a septic system, this requires approval from your local council but does not require chief executive approval. If you have not obtained the required approval from council, you will not be permitted to install a septic system on your property and, if you are located in water catchment areas or coastal areas where discharge may run into waterways, you will not be permitted to install a septic system.

When it comes to HSTPs, they need both local government approval and chief executive approval (or its equivalent) in accordance with Part 5 of the Plumbing and Drainage Act 2002 before they can be installed.

Maintenance and cleaning

When it comes to cleaning and maintenance, HSTPs require servicing in accordance with their State Accreditation Approval however septic systems do not, therefore it is wise to enquire regarding servicing charges when looking at installing a 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 a little different between the systems.

Running costs

A septic system is a much cheaper and more common option than a HSTP, however both are relatively cost effective to run relative to their respective dimensions. Septic systems do not require electricity to run and HSTPs do though, with the level needed depending on the model and type.

Other types of wastewater treatment

It is not just homes and buildings that produce wastewater, commercial kitchens are known to have a lot of grease build up that can make its way into the drain. To combat this a grease trap is installed which siphons out grease from the water allowing the cleaner water to be disposed of.
