How often does Water Corporation require a grease trap pump-out in Western Australia?

There is no single fixed interval. The frequency is set per venue in your trade waste agreement, based on your trap size and how much fat, oil and grease you produce. For most food venues that works out to somewhere between monthly and quarterly.

What happens if I miss a scheduled clean in Western Australia?

You risk a fine of up to $10,000, plus the real-world risk of an overflow. An emergency call-out to clear an overflowing trap typically costs three to four times a scheduled clean.

How do I prove my grease trap is compliant?

Keep the waste transport or disposal certificate from each pump-out. It records the volume removed and the licensed facility it went to, which is what the authority asks for if your account is reviewed.

Grease trap compliance in Western Australia

If your venue runs a commercial kitchen in Western Australia, you must pump out your grease trap on a schedule set by your water authority, using a licensed transporter. Miss it and you risk a fine and, more often, an overflow that costs far more to fix than the clean would have.

Who regulates your grease trap in Western Australia

Trade waste in Western Australia is regulated by:

Water Corporation, Perth and most of WA

How often you must pump out

Water Corporation sets your pump-out frequency per venue, written into your trade waste agreement. It depends on your trap size and your fat, oil and grease load, so a busy fryer-heavy kitchen is cleaned more often than a small cafe. For most venues the interval lands between monthly and quarterly. Treat any general advice as a starting point; the figure in your agreement is the one that counts.

Figures are maximums. The bigger practical cost is usually an overflow plus an emergency call-out at three to four times a scheduled clean.

What a compliant clean includes

A proper pump-out is a full extraction of solids and liquids, a scrape and inspection of the internal baffles, a refill with clean water, and a waste transport certificate you keep on file. That certificate is your proof of compliance.
