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.
Below-ground grease separators form part of grease management on suitable wastewater streams. Location, capacity, access and the rate of grease build-up all affect servicing.
Drain silt baskets catch solids before they travel further into the drainage system. Their condition and emptying interval determine how much local protection they continue to provide.
Grease capture units vary in capacity, internal arrangement and servicing needs. Identifying the installed unit is important before setting a cleaning or maintenance interval.
Sediment from site activity can enter surface-water drainage and settle in gullies, chambers or pipework. Understanding where it comes from and what lies downstream is as important as removing the deposit.
Starch separators serve drainage carrying starch-bearing wastewater. Maintenance has to reflect the separator installed, the process load and how quickly material accumulates.
