Commercial Grease Trap Overflowing — Emergency Fix

A grease trap overflow is an immediate FSSAI violation and slip hazard. Clethorix responds within 4 hours across Bangalore.

A grease trap overflow in a Bengaluru commercial kitchen is a simultaneous food safety emergency, FSSAI compliance failure, and slip hazard for staff. The greasy overflow contaminates surrounding floor surfaces, blocks the kitchen drain outlet, and — in an FSSAI inspection context — is visible photographic evidence of inadequate FOG (Fats, Oils, Grease) management. Clethorix's emergency response targets 4 hours from the first call.

What Causes This?

  • 1Cleaning interval has been exceeded — grease and solids have filled beyond 25% of the trap volume, the point at which the trap loses separation effectiveness
  • 2Sudden increase in kitchen volume — a catered event, seasonal spike, or extended operating hours produced more FOG than the normal schedule anticipated
  • 3Kitchen staff pouring hot grease or oil directly into the sink drain instead of the designated waste container
  • 4Trap mechanical failure — a damaged baffle or missing internal partition allows grease to bypass the trap and enter the main drain
  • 5Cold water shock — adding cold water to a trap full of hot grease causes rapid solidification of the grease layer, blocking the outlet

How Serious Is This?

A grease trap overflow is among the most serious FSSAI non-conformances for Bengaluru restaurants. It is visible evidence of FOG management failure, creates immediate slip-and-fall liability for staff, and — if grease enters the main sewer system — carries municipal violation risk under the Karnataka Municipal Corporations Act. In hotel kitchens, a grease overflow during service constitutes a food safety incident under FSSAI Schedule 4.

How Clethorix Fixes It

1

Emergency extraction: mechanical vacuum pump removal of grease, solids, and water from the trap within 4 hours of call-out

2

Trap cleaning and inspection: internal baffle, inlet, and outlet inspection to identify any mechanical failure requiring repair

3

High-pressure flushing of the drain line downstream of the trap to clear any grease that entered the main drain during the overflow

4

Same-day FSSAI compliance certificate and corrective action documentation to support any FSSAI response required

Prevention Tips

  • Establish and strictly follow a grease trap cleaning schedule — high-volume restaurants (100+ covers/day) need cleaning every 3–4 weeks
  • Install a grease level indicator or inspection port to allow kitchen staff to check the fill level without opening the trap
  • Train all kitchen staff: hot cooking oil must never be poured into any sink drain — only into designated waste containers for disposal
  • Enrol in a Preventix AMC with scheduled grease trap service so that cleaning never depends on a staff member remembering to book it

Frequently Asked Questions

How often should a restaurant grease trap be cleaned professionally in Bangalore?
High-volume restaurants (100+ covers/day): every 3–4 weeks. Moderate volume (50–100 covers): every 6–8 weeks. Clean when grease and solids fill 25% of trap volume.
Is a grease trap overflow a FSSAI violation?
Yes. A grease trap overflow is visible evidence of inadequate FOG management — a direct FSSAI non-conformance. Clethorix issues a signed FSSAI compliance certificate immediately after emergency cleaning.
Can I clean a commercial grease trap myself?
No. Commercial grease traps require mechanical extraction equipment. Manual cleaning is incomplete and creates serious health risks from hydrogen sulphide gas exposure above the grease layer.
