Wastewater Treatment

How is our wastewater treated?

The wastewater from the Town of Newman enters the Newman wastewater treatment plant (WWTP) where the main objective is to remove or break down what people have added to the water leaving their homes, businesses and schools.

The Newman WWTP treats wastewater through three stages, this includes:

Primary Treatment

Primary treatment removes the large solids entering the Newman WWTP through screen traps.

Secondary Treatment

Screened wastewater then enters a bioreactor which uses microorganisms (activated sludge) to break down nutrients (such as nitrogen) and organic solids.

The activated sludge is separated from the wastewater through a process called “wasting” which turns the activated sludge into bio-solids.

Tertiary Treatment

The wastewater flows into clarifiers which enable the removal of small particles from the water before it is chlorinated and distributed to Newman’s parks, ovals and green spaces.

How is the treated water used?

The treated water is RECYCLED locally!

It is pumped into the Town of Newman to irrigate our parks and ovals and greenspaces. The treated water is great for irrigation as it contains nitrates that plants love.

Caring for our environment!

We don't need to use drinking water to irrigate Newman’s parks, ovals and green spaces.

Treated water from our WWTP can do the job safely and reduces the stress on our drinking water sources!

The treated water is used through our Newman Recycled Water network, irrigating these places:

  • Capricorn Oval
  • Kangaroo Oval
  • Emu Oval
  • Goanna Oval
  • Boomerang Oval
  • East Newman Public Open Space
  • Shire of East Pilbara Administration Building
  • Red Sands Tavern
  • Newman High School

To Remember

We remove large quantities of unwanted solid waste from the wastewater treatment process each day like this.

Did you know?

When oil and grease hit the cool water in your wastewater pipes, they harden. They then combine with other waste like wet wipes to form a hard blockage known as a 'fatberg'.

These blockages can cause overflows which can be a health and environmental nightmare with wastewater backing up and overflowing into homes, backyards and local waterways.

What’s more, you could be looking at an expensive plumbing bill to fix a blocked drain!

This costs residents, industry and the Shire’s ability to water our greenspaces and oval with quality treated water.

The three main causes of blocked pipes and wastewater treatment problems are:

  • Flushing wet wipes, condoms, cleaning cloths, fabrics and bathroom products down the toilet.
  • Rinsing cooking fats and food scraps down the sink.
  • Pouring down chemicals, like solvents and cleaning products into the sink, drain or toilet.

While some brands of wet wipes might say that they’re flushable - they’re actually not! That's why they make up to 75% of all blockages.

Problem materials found in our wastewaterDamage caused to the wastewater system and environmentPrevention options

Solid items

  • Plastics
  • Rubber
  • Fibres 
  • Organic material​

Block wastewater pipes causing overflows.

Impacts on the efficient operation and cost of treatment.

Items can pass into treated water deposits, reducing the quality of treated water.

Never throw solid objects into the toilet.

Use a bin for unwanted or used items including disposable nappies, wet wipes, condoms, cotton-buds, tampons and cigarette butts.
  • Food waste
  • Oil & Grease
  • Milk or Liquid leftovers

Block wastewater pipes.

Increases chemical imbalances at the Newman Wastewater Treatment Plant leading to a low quality treatment process.

Make sure all sinks have a sink strainer.

Dispose of all oily products (food scraps, excess cooking oil, unused milk) in sealed containers and place in general waste bin.

Paint & Paint-Related Products Contains contaminates that affect the treatment process leading to environmental impacts for surrounding aquatic life.

Clean paint equipment in buckets instead of at drainage points. Empty buckets either in the garden or in sealed containers and dispose of in your household general waste bin.

Dispose of unwanted paint and paint-related products at the Newman Landfill (FREE of charge for residents).

Solvents and fuels

Toxic to bacteria used in wastewater treatment process. This can result in the water not being treated to a quality that is sufficient for the irrigation of Newman’s parks, ovals and public spaces.

Dispose of unwanted Solvents and fuels products at the Newman Landfill site (FREE of charge for residents).

Pesticides (including flea rinses) and chemicals

Toxic to bacteria used in wastewater treatment process. This can result in the water not being treated to a quality that is sufficient for the irrigation of Newman’s parks, ovals and public spaces.

Never pour unused pesticides, chemicals or flea rinses down the drain.

Dispose of leftover products at the Newman Landfill (FREE of charge for residents).

Think before you flush

Download the Water Corporation’s handy poster to remind your family what not to flush!

Remember to never flush anything other than the three P’s – pee, poo and (toilet) paper down the toilet. Anything other than toilet paper should go in the bin.

No one wants to see our town without our green spaces or without working sewerage systems. It’s up to everyone to help avoid blockages in our wastewater system.
