Identifying industrial drainage assets and maintenance needs
Oil separators, silt traps, catchpits and attenuation systems do different jobs. The maintenance approach depends on the asset installed, what drains to it and where the system discharges.
Asset details: manufacturer, model, capacity and drawings, where available.
Drainage duty: the area or process served and the oil, residues, sediment or other contamination it may receive.
Maintenance history: previous emptying or inspection, reported defects and recurring problems.
Access and discharge: cover locations, connected drains, outlet arrangement and known discharge destination.

The references below support the drainage, product and pollution-control information used in these guides. Manufacturer literature is specific to the product or system named and is not a specification for an unidentified installation. Regulatory guidance should be read within the jurisdiction and scope stated by the source.
Stainless steel floor gullies collect water and residues at floor level. Cleaning access depends on the installed gully and which baskets, traps or other removable parts are fitted.
Starch separators serve drainage carrying starch-bearing wastewater. Maintenance has to reflect the separator installed, the process load and how quickly material accumulates.
Surface-water pipework carries rainfall towards the site outfall, treatment or storage system. The route, pipe size and downstream assets all matter when a restriction or sediment problem is investigated.
Tray drainage channels provide linear collection across a drainage area. The installed layout, outlets and removable parts determine how the channel can be opened up and cleaned.
