Plan around risk and site use
A maintenance plan should reflect the drainage assets, occupancy, operating hours and consequence of a blockage or pump failure. The aim is to focus effort on known risks rather than applying the same frequency everywhere.
A useful drainage asset picture
Drawings, service records and previous incidents help identify recurring trouble spots, grease or silt risks, pumped systems and access constraints. CCTV evidence can be added where the condition of a run is uncertain.
Clear records and escalation
Facilities teams need findings that support a decision. Planned work can distinguish routine cleaning from defects that need a repair proposal, while urgent issues can be escalated with the affected area and operational impact clearly recorded.
