Why Grease Trap Maintenance Is Legally Required in Singapore
Under Singapore's Environmental Public Health Act and the Sewerage and Drainage Act, every food establishment and commercial kitchen discharging wastewater into the public sewer must install and maintain a grease trap or grease interceptor. The requirement exists to prevent fats, oils, and grease (FOG) from entering the sewer network, where they solidify, cause blockages, and create public health hazards.
PUB's Code of Practice on Sewerage and Drainage (CP40) governs grease trap design, installation, and maintenance. NEA enforces compliance through inspections and can issue:
- Corrective notices requiring immediate maintenance
- Fines up to $50,000 for first offences
- Mandatory closure of food establishments until compliance is achieved
- Court orders for repeated non-compliance
PUB CP40 and NEA Trade Effluent Regulations — What F&B Operators Must Know
CP40 requirements for grease traps:
Grease trap sizing: Must be sized to handle peak flow from the kitchen. Undersized traps are a common non-compliance issue.
Cleaning frequency: At minimum every 30 days for active F&B operations; NEA can specify more frequent cleaning based on inspection.
Effluent standards: Trade effluent discharged to sewer must meet pH 6–9, FOG below 100mg/L, BOD below 400mg/L.
Maintenance records: All cleaning visits must be documented. NEA inspectors can request records for the past 12 months.
AOT follows all CP40 requirements and provides full maintenance documentation for every service visit.
