Frequently Asked Questions — Underground Grease Interceptors
Yes. NEMA (National Environment Management Authority) and most county councils require all commercial food service operations to install a grease trap or grease interceptor to prevent fats, oils, and grease from entering the public sewer. Non-compliance can result in fines or operating licence revocation.
Sizing is based on your daily meal count and kitchen flow rate. A restaurant serving 100 covers per day typically requires a 500–1,000 litre interceptor. We size to NEMA guidelines and local authority requirements — contact us with your daily covers figure.
