What is a sewage treatment plant?

A sewage treatment plant is a system that helps treat domestic wastewater. There are home sewage treatment systems, otherwise known as HSTP, and the more commonly known septic system, which both treat wastewater in varying ways.

You may have also heard the following terms used for a HSTP, including :

  • On-site Sewage Facilities (OSSF)
  • Aerated Wastewater Treatment Systems (AWTS)
  • Aerobic Treatment Units (ATU)
  • Sewage Treatment Unit (STU)
  • Wastewater Treatment Plant (WWTP)
  • Aerobic Septic Systems
  • Wastewater Treatment Systems
  • Domestic Wastewater Treatment
  • Residential Wastewater Treatment System
  • BioCycle System

What does a sewage treatment plant do?

Through a series of chemical processes, a sewage treatment plant looks after the wastewater that is typically generated by a home.

Grey water

This is the water that is produced by showers, baths, washing machines, sinks and basins. This is the best water for recycling as there isn’t many additives.


This is the water that comes from the waste pipe of your toilet. This water contains a lot of infectious agents and can be broken down to be recycled to a smaller extent than grey water.

What a sewage treatment plant does is combine both blackwater and grey water and which is then processed using natural bacteria and other additives. The result is recycled water that can be used around the home and garden.

Benefits of a home sewage system

Having a sewage treatment plant for your home can help save money on your water by using the recycled wastewater on your gardens. The impact that your home has on the environment is decreased due to being more self-sufficient.

By having a treatment plant you are also minimising excessive use of groundwater thus being more environmentally friendly.
