Why is my water cloudy?

In Perth, residents are increasingly concerned about the appearance of cloudy water coming out of their taps. With a growing population and concerns about water supply, understanding what causes your water to become cloudy is essential to maintaining the health and well-being of residents.

Possible causes of cloudy water:

1. Air bubbles: One of the most common reasons behind cloudy tap water is trapped air bubbles. When water is pumped through the supply network, it can accumulate air as it rushes through pipes and fittings. This air dissolves into the water creating tiny bubbles that give it a cloudy appearance.
2. Hard water: Hard water contains a high concentration of dissolved minerals, like calcium and magnesium. These minerals can react with soap, forming a dense white precipitate known as limescale or “soap scum.” Consequently, hard water can cause murky or milky-coloured tap water resulting from dissolved impurities.
3. Plumbing issues: Corrosion or debris from aging plumbing systems may also contribute to cloudy tap water in Perth homes. Older pipes can break down, causing rust and sediment to flow into domestic water supplies.
4. Chlorine residuals: Chlorine is used by many water suppliers to disinfect tap water and prevent bacterial growth. However, at high levels, this chemical can react with organic substances in standing water, creating by-products that may cloud the appearance of your tap water.
5. Seasonal changes: Heavy rainfall events or changes in temperature can result in a higher concentration of dissolved minerals or organic matter within the source leading to cloudy tap water.

Addressing Cloudy Tap Water

1. Check with your local water supplier: Reach out to your local supplier and inform them about the issue so they may investigate any potential supply disruptions or quality issues.
2. Install a home filtration system: A whole of house water filtration system, such as a reverse osmosis or activated carbon filter, can help in reducing the presence of dissolved minerals, organic matter, and other impurities contributing to cloudy water.
3. Flush your pipes: Periodically flushing your pipes can help remove any trapped air, sediment or rust that may have accumulated over time.
4. Water softeners: Installing a water softener can help address hard water issues. These devices work by exchanging calcium and magnesium ions with sodium ions, reducing the mineral content and improving the clarity of your tap water.
5. Replace aging pipes: In some cases, it may be necessary to replace old or corroded pipes to resolve cloudy water problems effectively.

The appearance of cloudy tap water could be due to various factors like dissolved air bubbles, high mineral content, plumbing issues, chlorine residuals, or seasonal changes. Regardless of the cause, it is important to know that these conditions can mostly be remedied through actions like contacting your local water supplier, installing filtration systems or water softeners, flushing your pipes or replacing them if needed. Staying vigilant about the quality of your tap water will contribute to a healthier environment for you and your family.
