Sediment in water refers to tiny particles of sand, silt, rust, and other materials that can make your water appear cloudy or discoloured. These particles typically enter Perth's water supply through ageing infrastructure, soil erosion, or disturbances in water mains, resulting in water that may look, taste, or smell unpleasant while potentially damaging your home's plumbing system.
This page is part of our comprehensive guide to water contaminants in Perth. For an overview of Perth's water sources and treatment process, see our guide to Perth's drinking water supply.
Understanding Sediment in Perth's Water
While Perth's water treatment facilities work diligently to filter out sediment, various factors can introduce these particles into your home's water supply. The most common sources include:
- Old or corroding pipes that release rust particles
- Construction activity that disturbs water mains
- Seasonal changes in water sources and flow rates
- Natural mineral deposits in groundwater
- Sudden changes in water pressure
Perth's unique water supply system, which combines groundwater and desalinated water, can sometimes lead to varying levels of sediment contamination across different suburbs. Areas with older infrastructure typically experience higher levels of sediment, particularly during times of high water demand or after nearby construction work.
When sediment enters your water system, you may notice visible particles in your drinking water, a gritty texture, or discolouration ranging from reddish-brown (indicating rust) to white or tan (indicating sand or silt).
Potential Risks of Sediment in Your Water
While most sediment in Perth's water doesn't pose direct health risks, it can cause numerous problems for both your health and home:
Health Considerations:
- Gastrointestinal discomfort in sensitive individuals
- Potential for sediment to harbour bacteria or other contaminants
- Metallic taste that may discourage proper hydration
- Skin irritation for those with sensitive skin when bathing
Home and Appliance Damage:
- Clogged water filters requiring frequent replacement
- Reduced water pressure throughout your home
- Shortened lifespan of appliances like washing machines, dishwashers, and water heaters
- Damage to internal components of taps and fixtures
- Stained sinks, tubs, and toilets requiring additional cleaning
The financial impact of sediment-related damage can add up quickly, with premature appliance replacement costs potentially running into thousands of dollars.
