Grease Traps for Aged Care Facilities & School Kitchens

Why Institutional Kitchens Need Grease Traps

When people think of grease traps, they typically picture busy restaurant kitchens. But institutional kitchens—in aged care facilities, schools, universities, and hospitals—are subject to exactly the same trade waste regulations as commercial food businesses in Melbourne.

If your facility prepares meals on-site and washes dishes in a commercial kitchen, you need a grease trap. This applies regardless of whether you are a for-profit business or a not-for-profit institution. The water authority requirements are based on what your kitchen does, not your business structure.

This guide covers the specific considerations for aged care facilities and educational institution kitchens. For a complete overview of requirements across all industries, see our grease trap requirements by business type guide.

Aged Care Facility Requirements

Aged care facilities across Melbourne—from large residential care homes in the eastern suburbs to smaller facilities in regional areas—typically operate full commercial kitchens that produce three meals a day, seven days a week. While individual meal portions may be smaller than in a restaurant, the cumulative FOG output from preparing hundreds of meals daily is significant.

Typical Sizing

Most aged care facility kitchens in Melbourne require grease traps in the 500 to 1,500 litre range, depending on the number of residents and the extent of on-site cooking. Facilities that prepare all meals from scratch will need larger traps than those that rely partly on pre-prepared or delivered meals.

Cleaning Frequency

Quarterly cleaning is common for aged care facilities, though larger operations or those with higher-fat menus may require bi-monthly pump-outs. Your trade waste agreement will specify the maximum interval.

Health Inspector Expectations

Aged care facilities are subject to rigorous health and safety inspections under the Aged Care Quality Standards. While grease trap compliance is technically a trade waste matter rather than a food safety matter, health inspectors will note visible issues such as:

• Overflowing or foul-smelling grease traps
• Missing or expired cleaning certificates
• Evidence of grease backing up into kitchen drains
• Inadequate record keeping

A well-maintained grease trap with up-to-date compliance documentation demonstrates professionalism and supports your facility’s overall compliance posture.

School Kitchen Requirements

Schools with on-site canteens or tuckshops that prepare food—rather than simply selling pre-packaged items—are required to have grease traps. This includes government schools, independent schools, and Catholic schools across Melbourne.

Typical Sizing

School canteen grease traps are usually at the smaller end of the scale, ranging from 100 to 500 litres for most primary and secondary school kitchens. The key factors are the number of students served and the complexity of the menu.

Operational Considerations

School kitchens present unique operational considerations for grease trap management:

• Term-time only operation: Most school kitchens operate only during school terms, with extended shutdown periods during holidays. Grease traps should be cleaned before the end of each term to prevent FOG from sitting stagnant during breaks.
• Volunteer-run canteens: Many school canteens are run by parent volunteers who may not be aware of grease trap requirements. Kitchen managers and school facilities staff should ensure that all operators understand basic grease management practices.
• Budget constraints: School budgets are tight, and grease trap maintenance can seem like a low priority. However, the cost of a compliance failure—including emergency plumbing, water authority fines, and potential kitchen shutdowns—far exceeds the cost of regular preventive cleaning.

University and TAFE Kitchens

Universities and TAFE colleges with on-campus food outlets, commercial cookery training kitchens, or staff canteens must also comply with trade waste regulations. These facilities vary enormously in size and output:

• Student union food courts: Large campus food courts with multiple outlets may require triple interceptor systems, similar to shopping centre food courts.
• Commercial cookery schools: Training kitchens that teach commercial cooking produce significant FOG during practical classes, often across multiple cooking stations.
• Staff and student canteens: Campus canteens that prepare fresh food on-site need grease traps sized to their meal volume.

Compliance Framework for Institutional Kitchens

The compliance framework for institutional kitchens mirrors that of commercial food businesses:

• Trade waste agreement: Required with your local water authority (Yarra Valley Water, South East Water, or Greater Western Water).
• Trap sizing: Must comply with AS 4674-2004 and be approved by your water authority.
• Regular cleaning: At intervals specified in your trade waste agreement, performed by an EPA-licensed waste transporter.
• Documentation: Cleaning certificates, waste manifests, and trade waste correspondence must be retained for at least three years.

Institutions should appoint a specific staff member—typically the facilities manager or head chef—as the responsible person for grease trap compliance. This ensures continuity even when other staff change.

Common Challenges in Institutional Settings

Decentralised Management

In large aged care groups or school networks, grease trap management may fall through the cracks if there is no centralised oversight. Each facility needs its own cleaning schedule and documentation, even if the organisation manages multiple sites.

Ageing Infrastructure

Many aged care facilities and older schools have grease traps that were installed decades ago and may be undersized for current operations or in poor physical condition. If your trap is cracked, corroded, or no longer meets current standards, replacement should be prioritised.

Kitchen Renovations Without Trap Upgrades

When institutional kitchens are renovated—new equipment, expanded capacity, additional cooking stations—the grease trap must be reassessed. A trap that was adequate for the old kitchen may be undersized for the upgraded one.
