Grease trap service log template

A grease trap log that holds up when the inspector asks.

One sheet per trap, one line per cleaning: when it was serviced, how deep the grease and solids were, how much came out, and where it was hauled. Restaurants keep it by the trap; haulers leave it filled in.

Grease Trap / Interceptor Service Log

Pumping frequency and record-keeping rules come from your local FOG or pretreatment program. Many programs use the 25% rule (pump when grease plus solids reach a quarter of the trap's depth) and ask you to keep records on site. Check yours.

FOG + solids % = (grease depth + solids depth) / total liquid depth x 100. At or over 25%, many programs require pumping.

How to use it

Three things that make it hold up.

  1. Measure grease and solids depth before pumping, with a sludge judge or measuring stick, and write down the total liquid depth too. Without all three the percentage means nothing.
  2. Fill one line per cleaning, every time, including the manifest number from the hauler. Gaps in the log are what an inspector notices.
  3. Keep the log at the establishment with the hauler's manifests. Many programs require records on site for a set number of years.

The FOG report, with the 25% rule measured

PortaPro's Grease Trap / FOG Compliance Service Report records FOG and solids layers against total depth, with a service-required flag, plus hauler license, disposal facility and chain-of-custody signatures, kept with the job.

Grease trap software
Every trap on its own clock

Set Service every (days) on the trap, and the next due date counts from the last service. The Days Since Last Service report shows every site's due date, overdue first.

Due dates and reports
The history is one list per customer

Each completed visit comes back as a service record with the answers, photos, signature and time on site, filed on the restaurant. When the inspector asks, it's one list, not a filing cabinet.

Questions

What should a grease trap log include?

The date of each cleaning, the grease and solids depth against the total depth, the gallons removed, the hauler, the manifest number, the disposal facility, and who did the work.

What is the 25% rule for grease traps?

Many FOG programs require a trap to be pumped when the grease and solids together reach 25% of its liquid depth. Your local program sets the actual rule and frequency.

How long should a restaurant keep grease trap records?

It depends on the local program; several years on site is common. Check your city or sewer district's FOG ordinance.
