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.

Newman Waste Water Treatment Plant 
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!
















Capricorn Oval, Newman WA

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
We need your help
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 wastewater Damage caused to the wastewater system and environment Prevention options
Solid items including plastics, rubber, fibres and organic material Block wastewater pipes causing overflows.

Impacts on the efficient operation and cost of treatment processes including, removal, sorting, screening and transporting for disposal.

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.

Make sure all sinks have a sink strainer to trap solid items, like food and apple stickers.
Food waste, oil and grease, milk or other liquid leftovers Block wastewater pipes.

Increases chemical imbalances at the Newman Wastewater Treatment Plant leading to a low quality treatment process. This can cause environment impacts at surrounding creeks and rivers, harming aquatic life.
Make sure all sinks have a sink strainer fitted to trap food waste.

Dispose of oily products like food scraps, excess cooking oil, unused milk and other leftovers in sealed containers and place in your household general waste bin.
Paint and 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).

Look for non-phosphorus based solvents.
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 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.

The Newman Wastewater Treatment Plant is currently struggling to produce quality recycled water for our beautiful parks and ovals due to the amount of inappropriate materials being flushed down the drain/toilet.

The Shire requests that you DO NOT flush wet wipes, cleaning cloths, tissues, sanitary products, condoms, newspaper, paper towel, leaves, plastic or anything else!

They can block wastewater pipes, causing overflows and seriously impact the wastewater treatment process.

Chemicals, oils and cleaning products must be disposed of safety at the FREE Newman Landfill, and NOT flushed down the toilet or sink.

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.
Top tips for correct disposal
  • Keep a bin in your bathroom for:
    • wet wipes
    • cotton buds
    • sanitary items
    • condoms
    • cleaning cloths
    • tissues
    • dental floss
    • any other rubbish.
  • If you’re cleaning a bathroom, make sure you dispose of any cleaning cloths and fabrics in your household general waste bin.
  • Scrape food leftovers into the bin or compost.
  • Wipe greasy pans and dishes with a paper towel before washing up.
  • Pour any used oil, fatty liquids or old milk into a container and place it in the bin.
  • Use a sink strainer to catch small pieces of food and dispose of in your kitchen bin.
  • Dispose of used motor oil, paint or chemicals by bringing it in a sealed container to the Newman Landfill (FREE of charge for residents).
Trade Waste
Trade waste, or industrial waste, is any wastewater discharged from a business other than waste from office facilities or staff amenities.

If you're a business disposing of trade waste to the wastewater system, you need to ensure you have a Trade Waste Permit from the Water Corporation.

Apply for a Trade Permit or find out more here.
