Grease Trap Sizing Calculator
Static · formula-only · worked example computed when this page was built · no live data
The Grease Trap Sizing Calculator finds the design flow, liquid capacity, and cleaning interval for a kitchen grease interceptor. Example: for a commercial kitchen with two 30 L/min fixtures serving 200 meals/day, at a 0.75 simultaneous-use factor, Design flow = 45 L/min, Liquid capacity = 113.6 L, Cleaning interval = 1 day (per PDI G-101 | DENR DAO 2016-08).
How it works
Computed from your inputs per PDI G-101 | DENR DAO 2016-08. Anything the worked example does not state uses this calculator's standard default; the interactive version shows every input and lets you change it.
Worked example (Plumbing & Pumps)
Inputs: a commercial kitchen with two 30 L/min fixtures serving 200 meals/day, at a 0.75 simultaneous-use factor.
| Result | Value |
|---|---|
| Design flow | 45 L/min |
| Liquid capacity | 113.6 L |
| Cleaning interval | 1 day |
Computed by WorkHive's calculation engine when this page was built; standard: PDI G-101 | DENR DAO 2016-08.
How to use this calculator
- Read the worked example. It uses a commercial kitchen with two 30 L/min fixtures serving 200 meals/day, at a 0.75 simultaneous-use factor and shows every number in the method.
- Follow the formula with your own figures: it returns Design flow, Liquid capacity, Cleaning interval, computed per PDI G-101 | DENR DAO 2016-08.
- To compute interactively, open the Grease Trap Sizing Calculator inside WorkHive's free Engineering Design suite (link below). It runs the same method with your inputs.
FAQ
What is a grease trap sizing calculator PDI?
The Grease Trap Sizing Calculator is a free online tool that finds the design flow, liquid capacity, and cleaning interval for a kitchen grease interceptor. It shows the formula and a fully worked example so you can check the method, not just the number.
How is it calculated?
The result is computed from your inputs following PDI G-101 | DENR DAO 2016-08. The worked example on this page shows a real computation with real numbers.
Is the calculator free?
Yes. WorkHive is free: this worked example is open to everyone, and the interactive calculator runs inside the free Engineering Design suite after a free sign-up (your work is saved to your account). WorkHive is a free, offline-first maintenance platform built for Philippine industrial plants.
