Drainage and Wastewater
Grease Traps and Interceptors
Kitchen drainage odours, slow flow, grease accumulation or a scheduled interceptor requirement can justify this service. Give the kitchen loading, unit details, cleaning history and any recurring odour, grease or downstream flow problem. A description of the symptom is useful evidence for scoping, but it is not a remote diagnosis.

Overview
Trap capacity, kitchen loading, manufacturer instructions and downstream drainage all affect performance; cleaning alone cannot correct an unsuitable arrangement.
What the work can include
The agreed scope can include inspection and cleaning of grease traps or interceptors, records of condition and actions for connected drainage. The agreed scope names the unit, cleaning record and next review interval and states what will be supplied or tested at completion. Additional repairs, specialist design, testing or replacement are separate unless expressly included.
At completion, the client receives the unit, cleaning record and next review interval; any limitation, interface and the next action are stated.
Important decisions
Set a cleaning interval from kitchen loading, capacity and previous findings. Coordinate this choice with the commercial site’s operating constraints and client approval route.
Assessment and preparation
Before arranging the work, provide unit location and capacity where known, kitchen use, previous cleaning records, access, waste arrangements and recurring symptoms. For a portfolio, identify each site and retain consistent asset or area references so findings can be compared without merging different installations.
Provide the unit location and capacity where known, kitchen loading, previous cleaning records, access and waste arrangements. Note any recurring odour or slow-flow symptom.
How the work proceeds
Identify the unit, agree cleaning and inspection tasks, arrange safe access and disposal, record condition and review the interval from findings. At handover, the client can use the unit, cleaning record and next review interval to decide the next cleaning interval and any downstream action.
Cost, timing and disruption
Scope and price are affected by unit size, load, access, disposal, cleaning frequency and whether connected pipework or drainage also needs attention. For a commercial site or portfolio, provide the operating window, access contact and shutdown constraints relevant to grease traps and interceptors.
Sector and property applications
Commercial offices, education, retail and industrial sites may require grease traps and interceptors to be coordinated around kitchen operation, hygiene controls and waste arrangements. Use the full sector directory to place the site requirement in context.

Frequently asked questions
How often should a grease trap be cleaned?
There is no single safe interval for every kitchen. Use the manufacturer guidance, unit capacity, grease loading, cleaning records and findings from previous visits to set or review the interval. For portfolio planning, track the unit, cleaning record and next review interval separately for each site so the next service decision is clear.
Does cleaning the trap clear the downstream drain?
No. The trap and downstream pipework are separate parts of the system. If slow flow remains after the trap is cleaned, the connected drainage needs investigation. Where the work affects occupants or operations, agree access, shutdowns and retained-contractor interfaces before the activity is scheduled.
What records should a kitchen keep?
Keep the unit identity and location, cleaning date, condition, waste or disposal record, findings, actions and next review basis. That record supports a defensible maintenance interval. The completion information should state what was included, what could not be completed and what follow-up is needed.
Can a trap be replaced without checking the drainage?
Not safely. The replacement scope should consider kitchen loading, unit capacity, access, connections and downstream drainage so a new trap is not fitted into an unsuitable arrangement. For planned work, use the finding to decide whether further grease traps and interceptors or related remedial work is needed.
Knowledge and guidance
Read how often grease traps should be cleaned and what causes recurring drain blockages to set a cleaning interval from kitchen loading, capacity and previous findings. Use the service assessment to apply that guidance to the property or site. For a commercial site or portfolio, use this guidance alongside operating duty, access and the client approval route.
