Why this method statement is used
This method statement is used to define and communicate the approved procedure for carrying out method statement: temporary sanitation facility servicing and maintenance on site. It ensures the work is planned in advance, the correct resources and controls are in place, and all personnel understand responsibilities, sequence, quality requirements, and safety controls before work begins. It aligns site execution with the documented scope and acceptance expectations.
Who uses this method statement
This method statement is used by contractors, site supervisors, project engineers, QA/QC engineers, HSE officers, consultants, and client representatives. It serves as a shared reference for planning, execution, supervision, inspection, and approval of the activity on site.
When it is prepared and submitted
The method statement is prepared before the work activity starts and submitted as part of the pre-construction documentation package for review and approval.
Who reviews or approves it
The method statement is usually submitted to the client representative, consultant, resident engineer, or project management consultant for review and approval before the work commences.
Important approval note
This method statement is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all content must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.
For example: if your specification requires a departure from a referenced standard, that departure must be documented and approved separately — this method statement will not capture that automatically. Always verify against your applicable drawings, specifications, and regulatory requirements.

Frequently asked questions
A common benchmark is weekly servicing (pump-out, clean, disinfect) for one unit per 10 workers on a 40-hour workweek. Increase frequency for higher occupancy, hot weather, or extended shifts. Verify per project specifications and local laws.
Use disinfectants compliant with BS EN 1276 and BS EN 13697 for non-porous surfaces, following manufacturer contact times, typically 5–10 minutes.
Complete Waste Transfer Notes with licensed carrier details and obtain disposal receipts from a permitted facility. Maintain a tanker log and chain-of-custody records.
Optional ATP surface testing on touchpoints can be performed. A benchmark pass level is <100 RLU; units failing are re-cleaned and re-tested. Benchmarks must be verified per project QA plan.
Stop the source, contain with absorbents/booms, protect drains, recover waste using vacuum or absorbents, disinfect the area, dispose of contaminated materials per local regulations, and report the incident. Conduct periodic spill drills.
