A grease trap cleaning log is a dated record of inspections, cleanings, waste removal, and follow-up work for a grease trap or interceptor. Use the printable template below to document each service consistently, then adjust the fields to match your equipment, service provider, and local requirements.
What a Grease Trap Cleaning Log Tracks
A grease trap keeps fats, oils, and grease from entering plumbing and sewer lines by separating them from wastewater. Depending on the site, the device may be a small unit under a sink or a larger outdoor interceptor. A log creates a history of what happened to the equipment: when it was checked, what service was performed, who did the work, and whether anything needs attention.
The record is useful for more than remembering the last pump-out date. It can help staff notice that a trap is filling faster than usual, show a service provider what was done previously, and make it easier to answer questions from a property manager or an inspector. A log is evidence of recorded work, not proof by itself that the equipment is functioning properly or that every applicable rule has been met.

Sample entry — fictional example only:
| Date and time | Trap location or ID | Event type | Condition or observations | Work performed | Waste amount and unit | Service provider or staff | Disposal record or destination | Follow-up needed and due date | Initials or signature |
|---|---|---|---|---|---|---|---|---|---|
| May 14, 2026, 8:30 a.m. | Kitchen sink unit A | Cleaning | Visible grease buildup; lid seated | Contents removed; unit checked | 18 L | Jordan Lee, fictional staff member | Receipt R-104, fictional | Check lid seal by May 21 | JL |
Use the units and disposal details your provider supplies. Do not treat the fictional quantities, dates, or observations as recommended thresholds.
How to Fill In Each Entry
Make the entry as soon as practical after the inspection or service, while the details are fresh. Identify the equipment clearly: a business with several traps should use a location name or asset ID that staff can distinguish, such as “dish area, under sink” rather than simply “grease trap.” Record the date and time, and mark whether the visit was a routine check, a full cleaning, a repair, or another kind of service.
Describe observations in plain, factual language. For example, “odor noticed near lid” is more useful than “bad condition,” and “water visible around the access cover” is clearer than “leaking?” If a measurement is taken, write down what was measured, the value, and the unit. Avoid guessing: if the service person does not provide a quantity or measurement, write “not recorded” rather than inventing one.
In the work field, distinguish what was actually done from what was recommended. “Contents removed and baffles checked” describes work; “replace damaged seal next visit” describes a recommendation. Add the name or identifier of the person who performed or verified the work. If there is a service receipt, work order, or disposal document, note its reference and keep the document with the log or in a linked file.
What Counts as Cleaning or Inspection
People sometimes use “cleaning,” “pumping,” and “inspection” as if they mean the same thing. They do not always describe the same scope of work. An inspection may be a visual check or a review of the unit’s condition. A pump-out generally refers to removing accumulated contents. A more complete cleaning service may include additional steps, depending on the equipment and the provider’s scope. The log should name the service that was performed, not just use a general word such as “done.”
Ask the service provider to state what was included on the receipt or work order. If the provider reports a blockage, damaged part, unusual accumulation, or other concern, record the finding and whether it was repaired, referred for repair, or left unresolved. Do not assume that a pump-out included repairs or that a brief visual check means the unit was emptied. Clear descriptions prevent confusion when a different employee or contractor reviews the record later.
Choosing a Cleaning Schedule
There is no single interval that fits every grease trap. The appropriate schedule can depend on the trap’s size and design, the amount and type of food preparation, the volume of wastewater, equipment instructions, and applicable local rules or permit conditions. A small unit serving a busy kitchen may need attention on a different schedule from a larger interceptor serving a lower-volume operation.
Use the schedule required by the relevant authority or your equipment and service guidance where those requirements apply. If no interval is specified in the information available to you, ask the local wastewater or plumbing authority, property manager, or a qualified service provider what applies to your location. Keep the schedule itself in a prominent place and use the log to record actual dates, rather than relying on memory or a calendar reminder alone.
Review the record for patterns. If inspections repeatedly note heavy buildup, odors, slow drainage, or a need for unusually frequent service, raise the pattern with a qualified provider. The log can help explain what has changed, but it cannot identify the cause on its own. Likewise, a clean-looking entry is not a reason to extend a required service interval without checking the applicable instructions.
Details That Make Records More Useful
Consistent entries are easier to compare than elaborate but irregular notes. Agree on names for locations, units for quantities, and short descriptions for common event types. If your site has multiple traps, give each one a stable identifier and use it on service receipts as well as in the log. Keep a key that connects those identifiers to their physical locations.
- Date and time: Record when the visit occurred, not when someone later entered it into a spreadsheet.
- Event and scope: Identify inspection, cleaning, pump-out, repair, or another service, and briefly state what was included.
- Findings: Note observable conditions, measurements, or issues reported by the provider without speculation.
- Quantity and units: Include the amount removed only when it is supplied or measured, and label the unit.
- Responsibility: Identify the staff member or provider and the person who completed or checked the entry.
- Supporting records: Reference receipts, work orders, photographs, or disposal paperwork when available.
- Next action: Name the required follow-up and a target date or responsible person, if one is known.
Paper Logs, Digital Logs, and Record Storage
A printed sheet is simple to keep beside a maintenance binder and can be completed when service takes place. Its disadvantages are that handwriting may be difficult to read, pages can be misplaced, and a paper log may not be accessible to staff at another location. Use a consistent form, write legibly, and store completed pages in date order.
A spreadsheet or other digital record can be searched, sorted by trap ID, and backed up. It also makes it easier to attach or reference service documents. However, a digital file is only useful if staff know where it is, entries are made consistently, and the information remains available when needed. Whichever format you choose, avoid keeping the only copy on a device or in a folder that could be lost. If both paper and digital versions are used, decide which is the authoritative record and how corrections will be reflected in both.
Keep the log and supporting documents for the period required by local rules, permits, contracts, or your organization’s record policy. Requirements vary, so do not assume a universal retention period. If you are unsure what records apply to your site, ask the appropriate local authority or a qualified professional.
Common Logging Mistakes
A frequent mistake is recording only “cleaned” without saying which trap was serviced or what the visit included. Another is entering a scheduled date as though the work happened that day. If a visit is postponed, record the actual service date and note the change where useful. Never backfill an entry from memory as if it were contemporaneous; if you need to add a late note, label it as a late entry and state when it was added.
It is also easy to leave follow-up notes open indefinitely. Give each issue an owner or next step, then add a dated entry when it is resolved. Do not erase an unfavorable observation just because the problem was repaired; retain the original observation and record the corrective work separately. This preserves a clear history. Finally, avoid treating an invoice alone as a complete log: it may show that a charge occurred without identifying the trap condition, work details, or next action.
Safety and Scope of the Log
A log is a documentation tool, not a reason for untrained staff to open, enter, or service equipment beyond their role. Follow site procedures and the equipment provider’s instructions. Grease traps and interceptors can involve slippery surfaces, unpleasant or harmful exposure, heavy covers, and plumbing hazards. Do not enter a tank or confined space; such work requires appropriate training and controls. If a task appears unsafe or requires specialized service, stop and contact a qualified provider.
Record safety concerns factually, such as a damaged cover, spill, or suspected leak, and report them through the site’s normal process. Do not write that an area is safe merely because it was serviced. If the work requires protective equipment or special handling, follow the applicable workplace procedures rather than relying on this template as a safety manual.
Frequently Asked Questions
What should a grease trap cleaning log include?
At minimum, identify the trap, record the service date, describe the event and work performed, name the person or provider, and note observations and follow-up. Add quantities, units, and disposal-document references when those details are available.
How often should a grease trap be cleaned?
There is no universal interval for every site. Follow applicable local requirements, permit conditions, equipment guidance, and qualified service advice. The right schedule may depend on the equipment and how the kitchen operates.
Is a pump-out the same as a full cleaning?
Not necessarily. “Pump-out” commonly refers to removing contents, while the scope of a cleaning or inspection can vary by provider and equipment. Ask what was included and record the work in specific terms.
Can I use this template for an outdoor interceptor?
Yes. Use the location or ID field to identify the interceptor, and adapt the observations and measurement fields to the information your provider supplies. Larger systems may have service documents or site-specific requirements worth referencing in the log.
How long should I keep grease trap cleaning records?
Retention periods depend on applicable local requirements, permits, contracts, and organizational policy. Check the rules for your location and keep associated receipts or service records together for the required period.
Does keeping a log prove that my site is compliant?
No. A complete log can help document maintenance, but it does not by itself establish that equipment, service frequency, disposal, or other practices meet every applicable requirement. Confirm site-specific obligations with the appropriate authority or a qualified professional.
