A stormwater drain is designed to manage runoff from rain, especially during periods of heavy rainfall. When it rains, water runs off your roof and hard surfaces, collecting natural materials like leaves, dirt, and other debris. This water is channelled through your roof gutters, downpipes, and into a network of stormwater pipes and drain openings.

A well-functioning stormwater system directs excess water into local government drainage infrastructure or nearby water bodies like rivers, lakes, or the ocean, helping to prevent flooding, water pooling, and structural damage.

In many areas of Perth, the landscape and infrastructure don’t naturally allow water to flow freely. Flat blocks, poor installation, or ageing systems can cause water to pool, back up, or even flow uphill, especially during the wet season.

If your stormwater drain is blocked, it can quickly lead to:

• Overflowing gutters and drains

• Pooling water around your foundations

• Foul odours and damp patches

• A breeding ground for mould, mosquitoes, and bacteria

This is why routine stormwater drain cleaning and preventative maintenance are so important.

A blocked stormwater drain pipe can be caused by several issues, including:

• Tree roots infiltrating cracked pipes

• Build-up of leaves, dirt, and debris particles

• Dislodged or damaged drain grates

• Sanitary towels, plastic bags, and other foreign objects

• Poor water flow due to collapsed or undersized piping

These issues often start small but can lead to serious blockages and even broken pipes if left untreated.

Some homeowners try DIY methods such as:

• Pouring hot water or boiling water down the pipe

• Using caustic soda (with caution)

• Attempting a flush using a garden hose

These methods may help with minor clogged drains, but they’re unlikely to resolve severe blockages. For long-term protection, it’s best to call in a professional plumber with the tools and expertise to properly inspect and clear the system.
